Research checked: 19 September 2026
London has hundreds of investors, but finding the right venture capital firm is not as simple as searching for the biggest name.
One VC may invest before a startup has made its first sale. Another may only look at companies that are already growing quickly. Some publish exactly how much they invest. Others do not. Some let founders upload a pitch deck online, while others expect founders to contact individual investors.
For this 2026 guide, Companies.London checked the current websites, investment pages, founder FAQs, portfolio pages and recent announcements of 10 venture capital firms with a London presence.
We did not rank the firms from best to worst. We also did not use estimated investment amounts where the investor does not publish one.
What Did Companies.London Find?
Our check found a useful difference between London VC firms.
Only a small number of the firms in this guide publish a clear standard or initial investment amount for founders.
For example, Octopus Ventures says its standard pre-seed investment is £100,000, while Seedcamp says its normal first cheque is between $350,000 and $1.25 million. BGF publishes ranges of £3 million to £10 million for its Early Stage team and £3 million to £30 million for its Growth team.
Other well-known investors do not publish one simple first-cheque figure because deals can vary greatly.
We also found that several firms make it easy to approach them directly. Octopus Ventures, Seedcamp, Molten Ventures and BGF all provide clear founder pitching routes on their current websites. Kindred Capital openly provides an email address and says that it is never too early for a founder to speak with the team.
That is useful information for founders because not every London VC follows the same fundraising process.
Is London Still the Centre of UK Venture Capital?
London remains the largest part of the UK equity investment market, but its share is slowly falling.
British Business Bank figures published in July 2026 show that UK smaller businesses received £12.3 billion of equity investment in 2025.
London accounted for 57% of UK equity investment, down from 60% in 2024.
One of the biggest changes is artificial intelligence. AI businesses received 44% of all smaller-business equity investment in 2025, the highest share recorded by the British Business Bank.
This means London remains important, but founders should not assume that all UK venture funding is concentrated in the capital.
10 London Venture Capital Firms at a Glance
Important: “No figure found” does not mean the investor will not invest. It means we did not find a simple current founder-facing cheque size on the official pages checked on 19 September 2026.
1. Atomico
Website: Atomico
Atomico is a London-based technology investor founded in 2006 by Skype co-founder Niklas Zennström.
That makes 2026 Atomico’s 20th year.
Atomico says it has now invested through six funds and is designed to support European technology companies from inception through to IPO and beyond.
What Does Atomico Invest In?
The important point for founders is that Atomico is not limited to one small startup stage.
Its approach is focused on ambitious technology businesses that can grow beyond their home country.
Atomico’s current messaging places particular importance on strengthening European technology and helping European companies become global businesses without having to leave Europe.
Does Atomico Publish Its Normal Investment Size?
We did not find one current standard founder-facing investment range during our check.
That is worth knowing because older articles around the web sometimes give fixed Atomico cheque ranges. Unless Atomico itself currently confirms those figures, founders should not treat them as guaranteed.
Verified London address: 29 Rathbone Street, London W1T 1NJ.
2. Index Ventures
Website: Index Ventures
Index Ventures started in Geneva in 1996 and later expanded into London. It now has offices in London, Geneva, New York and San Francisco.
Its portfolio covers many areas of technology, including financial technology, AI, business software, consumer technology and healthcare.
What Stage Does Index Ventures Invest At?
Index says clearly that it backs companies from seed to IPO.
Its Origin funds focus specifically on seed-stage businesses, while the wider Index platform can continue investing as companies grow.
That makes Index different from a fund that only writes the first cheque and then moves on.
Is Index Still Investing in 2026?
Yes.
For example, Index led a $75 million Series B for fomo in June 2026. It also participated in Wonderful’s $150 million Series B earlier in the year.
These deals also show that Index invests across very different stages and company sizes.
Can Founders Submit a Pitch Through the Contact Page?
The current Index contact page lists its offices and general company details, but we did not find a dedicated public startup pitch form on that page during our check.
Founders should therefore research the Index investors covering their particular sector instead of sending a completely untargeted approach.
3. Balderton Capital
Website: Balderton Capital
Balderton Capital has been investing in European technology companies since 2000.
The firm says it has backed more than 300 companies and raised $5.7 billion to invest from seed to IPO.
Its London office is at The Stables, 28 Britannia Street, London WC1X 9JF.
What Does Balderton Invest In?
Balderton focuses on European-founded technology companies.
Its portfolio shows that it can enter at several points. For example, it backed Revolut at seed, Wayve at Series A and other businesses at later stages.
What Is Balderton Looking at in 2026?
In September 2026, members of Balderton’s investment team highlighted areas including:
AI infrastructure, enterprise AI, cybersecurity, maritime technology and technologies connected with European security and infrastructure.
Its portfolio has also remained active. Recent 2026 announcements include The Exploration Company’s $450 million Series C, Conveo’s $50 million round and Lovable’s $400 million Series C.
Does Balderton Help Founders Before They Raise?
Yes, in another way.
Balderton runs Balderton Launched, a free six-month programme at its London headquarters for people at a very early building stage.
The programme takes no equity and can include people who are still working out their idea. Applications were open for its Autumn 2026 programme when checked.
That is useful to know because it is different from applying directly for a normal VC investment.
4. LocalGlobe
Website: LocalGlobe
LocalGlobe is part of Phoenix Court and concentrates on pre-seed and seed investment.
Phoenix Court then has other investment vehicles for companies at later stages. Latitude focuses on breakout companies around Series B and beyond, while Solar covers later private and public-market stages.
How Early Does LocalGlobe Invest?
Very early.
Its current positioning describes LocalGlobe as a long-term partner for founders from pre-seed and seed.
Its portfolio has included businesses such as Monzo, Cleo, Mistral, Tide and TravelPerk.
The wider Phoenix Court portfolio page currently lists hundreds of companies across LocalGlobe, Latitude and Solar.
What Has Happened in 2026?
LocalGlobe’s 2026 activity includes early-stage businesses working across AI, biotechnology, materials and other technical fields.
Its first-quarter update highlighted companies including Anzen Industries and baCta, while Phoenix Court has continued backing companies across different growth stages.
Can Founders Apply Through the LocalGlobe Page?
Here is an important detail from our check.
The LocalGlobe pages we reviewed clearly explain the investment stage and show the portfolio, team and London office, but we did not find a simple “submit your pitch” or “apply for funding” button on the LocalGlobe page checked.
Its listed London location is 2 Brill Place, London NW1 1DX.
5. Octopus Ventures
Website: Octopus Ventures
Octopus Ventures gives founders more public information about its investment process than many VC firms.
It invests across seven areas:
B2B software, bio, climate, consumer, deep tech, fintech and health.
It says it has backed more than 180 teams and has completed 32 successful exits.
How Much Does Octopus Ventures Invest?
This is one of the clearest investment policies we found.
For pre-seed, Octopus says its standard investment is £100,000.
For seed, Series A and later rounds, investments typically start from £1 million.
Octopus says its main sweet spot runs from pre-seed to Series A, although it can also invest later.
Can You Pitch Octopus Directly?
Yes.
Its website has separate submission routes for:
pre-seed funding and seed, Series A, Series B and beyond.
For pre-seed companies, Octopus says it can sometimes invest before a product has even been developed.
It also says it usually makes its pre-seed decision within about two weeks after the first discussion.
That level of detail makes it easier for a founder to know whether it is worth applying.
6. Seedcamp
Website: Seedcamp
Seedcamp has focused on first-cheque investment in European technology startups since 2007.
Its approach is heavily centred on pre-seed and seed businesses.
How Much Does Seedcamp Invest?
Seedcamp currently publishes one of the clearest numbers in this guide.
Its normal first cheque is between $350,000 and $1.25 million.
It says companies can approach it while they are still pre-product or pre-revenue.
Seedcamp normally focuses on companies based in Europe and Israel, or businesses with a strong European connection.
What Changed at Seedcamp in 2026?
A major change came in June 2026 with Fund VII.
Seedcamp announced $320 million in new funds:
$220 million for its first-check Fund VII and $100 million for its Select fund, which can continue supporting portfolio companies through Series B and later rounds.
Its 2026 investment activity has included businesses working in voice AI, financial infrastructure, surgery technology, cybersecurity, biotechnology and other areas.
Can Founders Pitch Seedcamp?
Yes.
The current Seedcamp site includes a Pitch Us route.
Seedcamp also says that when there is a strong fit, it tries to run the investment process within about two weeks of meeting the founder.
7. Kindred Capital
Website: Kindred Capital
Kindred Capital is a London early-stage venture investor founded in 2016.
One thing makes its investment model unusual.
Founders backed by Kindred receive a share in the wider success of the investment fund through what Kindred calls Equitable Venture.
How Many Businesses Does Kindred Back?
Kindred says it has normally invested in around six to eight early-stage startups each year since 2016.
Its current investment areas include:
health and bio, computing, industrial technology, robotics, security, energy, applied AI, financial infrastructure and space.
Its portfolio shows new investments dated 2026, including Lithosquare and companies that remain in stealth.
How Early Can You Contact Kindred?
Kindred’s answer is unusually clear:
there is no stage that is too early for a founder to start talking to the firm.
The company publicly lists hello@kindredcapital.vc for contact.
Kindred does not currently publish one standard investment amount on the pages we checked, so founders should not rely on third-party websites claiming a fixed cheque size.
8. Notion Capital
Website: Notion Capital
Notion Capital has a much narrower investment focus than many firms in this guide.
It describes itself as an early-stage European business software investor.
This makes it easier for founders to decide whether the fund is relevant.
A consumer fashion startup, for example, would probably not start its VC search with a specialist business-software fund.
What Type of Software Interests Notion?
Notion currently divides its focus into four broad areas:
Software as a Service, AI-based services as software, software that works with the physical world, and fintech.
The firm’s portfolio includes businesses such as Mews, GoCardless, Paddle, Aikido Security, Upvest and Quantum Systems.
How Large Is Notion Capital?
Notion currently reports:
$1 billion in assets under management and more than 200 companies invested in.
Its main website says it focuses on helping business-software companies make the journey from around $1 million to $100 million in revenue.
Is Notion Investing in 2026?
Yes.
In March, Notion led Origin’s $30 million Series A+.
In May, it co-led Pivot’s $40 million Series B. Its 2026 news also shows investments and follow-on activity involving several other software companies.
The current website also provides a “Get in touch” route for people looking to connect with the firm.
9. Molten Ventures
Website: Molten Ventures
Molten Ventures needs a careful explanation because older information about the firm can be confusing.
Molten acquired Forward Partners, but that does not mean Molten Ventures should simply be described as Forward Partners or given old Forward Partners contact information.
Today, Molten invests in high-growth private technology businesses across the UK and Europe.
What Does Molten Ventures Look For?
Molten says it focuses on businesses with strong technology, intellectual property, barriers to competition and potential to grow internationally.
Its four main areas are:
consumer technology, digital health and wellness, AI/deep tech/hardware, and cloud/enterprise software/SaaS.
Its core direct business is focused heavily on growth-stage companies, while the wider Molten structure also has access to earlier-stage businesses through other investment vehicles.
How Large Is Molten’s Portfolio?
As of 31 March 2026, Molten said it had a portfolio of more than 100 companies.
It also reported more than £1 billion deployed and more than £800 million realised from exits since IPO.
Can Founders Pitch Molten Directly?
Yes.
Molten’s current contact page specifically asks companies looking for investment to send a pitch deck.
Its London office is at 20 Garrick Street, London WC2E 9BT.
10. BGF
Website: BGF
BGF is different from a normal seed-only VC because it invests at both early stage and growth stage.
Its Early Stage team focuses specifically on deep tech and life sciences.
What Does BGF’s Early Stage Team Invest In?
To qualify for its published Early Stage criteria, a company should normally be:
headquartered in the UK or Ireland, privately owned, working in deep tech or life sciences, protected by intellectual property and at late-seed to Series B stage.
BGF says its normal initial Early Stage investment is £3 million to £10 million.
Its Early Stage team says it has deployed more than £325 million, backed more than 70 companies and completed over 140 transactions since 2019.
What About More Established Businesses?
BGF’s Growth team is different.
It generally looks for established UK or Irish businesses with a strong track record. Technology businesses normally need around £3 million or more in annual recurring revenue under its published criteria.
Growth investments start from £3 million and can reach £30 million initially.
Is BGF Active in 2026?
Very much so.
Its 2026 Early Stage activity includes investments in circuit-simulation company Mach42, AI business Luffy AI, battery technology company Gaussion, TRIMTECH Therapeutics and medical-device company CroíValve.
BGF also provides a direct Pitch us route for Early Stage companies and a separate registration route for Growth businesses.
Which London VCs Accept Very Early Startups?
If your company is only at idea, pre-product or pre-revenue stage, do not approach every VC in this article.
Based on their current published information, some of the clearest early-stage options are Octopus Ventures, Seedcamp, LocalGlobe and Kindred Capital.
Octopus says it can occasionally invest before a product has been developed. Seedcamp accepts companies from pre-product and pre-revenue stage. LocalGlobe focuses on pre-seed and seed, while Kindred says it is never too early to start a conversation.
That does not mean they will fund every early idea. Founders still need a strong problem, a believable solution and a team capable of building the business.
Which London VCs Publish Their Investment Size?
One of the clearest findings from our research is that many major VC firms do not publish a fixed cheque size.
Among the companies checked, three make their main founder-facing investment ranges especially clear.
Molten Ventures also publishes investment information for individual investment vehicles. For example, its EIS strategy says the majority of that vehicle’s funds are targeted at later-stage growth rounds of £5 million to £20 million or more. That figure should not be confused with a universal Molten first-cheque size.
If a fund does not publish its ticket size, founders should ask rather than rely on estimates copied from directories.
How Should You Choose a Venture Capital Firm?
Start with stage, not brand name.
If you have only an idea, a growth-stage fund is unlikely to be the right first call.
Next, look at the investor’s sector.
Notion is heavily focused on business software. BGF’s Early Stage team focuses on deep tech and life sciences. Octopus has seven clearly stated sectors. Other firms such as Index and Balderton have a wider technology focus.
Then look at the firm’s recent investments.
A portfolio from five years ago tells you what an investor liked five years ago.
A deal announced in 2026 tells you much more about what the investment team is looking at now.
What Should You Check Before Sending a Pitch?
A founder should answer a few simple questions before contacting a VC.
Does this investor fund companies at my stage?
Does it invest in my industry?
Does it invest in my country?
Does it publish a minimum investment size?
Has it backed a direct competitor?
Who on the investment team works in my sector?
Is there an official pitch form, or should I contact an investor directly?
Doing this research takes longer than sending the same pitch deck to 100 investors, but it can make each approach much more relevant.
What Should a Simple VC Pitch Explain?
A good pitch should be easy to understand.
Start with the problem.
Explain who has the problem and why it matters.
Then explain your solution.
Show what you have built, what makes it different and why customers would choose it.
Investors will also want to understand your market, your competitors, your team, any early customer results and how you plan to use the money.
Octopus Ventures says the first things it wants to understand are the problem, the proposed solution and why the founding team is the right team to solve it.
Do You Need a London Office to Raise Money From a London VC?
Not always.
Many London-based venture capital companies invest across Europe or further abroad.
Octopus Ventures says it has a pan-European focus. Seedcamp mainly focuses on Europe, Israel and companies with a strong European connection. Atomico is focused on helping European technology companies grow globally, while Index operates across both Europe and the United States.
So a founder should check the investor’s geography rather than assume a London address is required.
What Is Changing in Venture Capital in 2026?
AI is the clearest change.
British Business Bank data shows that AI companies received 44% of smaller-business equity investment during 2025. AI represented 26% of all deals, and AI-related investment value increased 48% year on year.
We can also see the change in the portfolios of the VC firms themselves.
Balderton is discussing frontier AI and AI infrastructure. Notion is investing in AI-driven business software. Kindred’s portfolio includes applied AI and compute infrastructure. Seedcamp’s recent investments include AI companies in finance, security, healthcare and chip design.
At the same time, deep technology, biotechnology, defence technology, robotics, energy and advanced computing are receiving more attention.
Another change is geography.
London still received most UK equity investment in 2025, but its share fell to 57%. The North West, Scotland and South West recorded strong increases.
The UK Government also announced another £100 million phase of the Investor Pathways Capital Initiative in August 2026, with plans that could support up to 10 new venture funds around the country.
Are These the “Best” Venture Capital Companies in London?
There is no honest way to name one venture capital company as the best for every founder.
A £100,000 pre-seed investor and a £10 million growth investor are solving completely different funding problems.
That is why Companies.London has not given these firms star ratings or ranked them from first to tenth.
Instead, this guide focuses on information a founder can check:
investment stage, sector, published cheque size, geographical focus, founder contact route and recent activity.
That gives founders a better starting point for making their own shortlist.
Final Thoughts
London remains the UK’s biggest venture capital centre, but founders now have a much wider range of investors, stages and funding routes to understand.
The biggest lesson from our 2026 research is simple:
do not choose a VC because its name is famous. Choose investors whose current strategy matches your company.
If you are at pre-seed, look for investors that actually say they invest that early.
If you need £5 million, do not spend weeks pitching a fund whose normal first cheque is £350,000.
If you are building business software, look for investors with experience in business software. If you are developing biotechnology or advanced hardware, search for investors that understand those industries.
And always check the VC firm’s own website immediately before pitching.
Investment teams, funds, cheque sizes and sector priorities can change.
Our Research Method
Companies.London reviewed publicly available information from the official websites of Atomico, Index Ventures, Balderton Capital, Phoenix Court/LocalGlobe, Octopus Ventures, Seedcamp, Kindred Capital, Notion Capital, Molten Ventures and BGF.
We checked investment-stage information, published investment amounts, portfolio pages, founder contact routes and recent 2026 announcements.
Where a company did not publish a clear investment amount, we have said so rather than estimating one.
Where we did not find a dedicated pitch form on the pages checked, we have described that as our finding rather than claiming that no contact route exists anywhere.
