Thirty years ago, we built Index around one conviction: great founders can come from anywhere, and our job is to find them early and stay with them.
Today we're announcing new funds — $3.5B across seed, venture, and growth.
The best is yet to come.

It’s been an absolute privilege partnering with @spectorb @amspector100 @aidanmantine and the rest of the incredible @flappyairplanes team.
We’re thrilled to double down and colead another round and I’m honored to join the board.
Efficiency in compute + data will unlock massive new opportunities, and there’s no better team to solve it than this one.
We’ve spent the past year developing new primitives for GPUs. We believe this enables new algorithms to change how machines learn, open new markets, and dramatically reshape AI’s cost structure.
We have raised a $1 billion Series A, co-led by Index and Lux.

Duvo is one platform where people and AI agents run operations together, and has already unlocked $100M+ for customers.
We’re proud to back @TomasCupr & @Duvoai again with today’s $32M Series A.
We've raised $32M in Series A funding to become the one platform enterprises run their operations on. 🚀
Led by @balderton, with participation from @IndexVentures, @northzoneVC and @CredoVentures, this brings our total funding to $48M and fuels our global expansion.
McKinsey sizes the long-term potential of generative AI at $4.4 trillion a year in added productivity. Most of it sits in the same place: every enterprise has hidden money trapped in broken processes, disconnected systems and manual work.
We're building the Enterprise Execution OS to release it. One platform where people and AI agents run operations together. We map how work actually happens, improve it, and automate it across existing systems. In weeks, not years.
And we've already delivered over $100M in annualized impact across dozens of enterprises.
Our mission is simple: raise the GDP of every employee. Unlock every business's working intelligence and empower people to create more value.
A huge thank you to our customers, investors, partners and the entire Duvo team who got us here.
The next chapter starts now. And we're just getting started. 🌎

1/ Today we’re launching an open letter calling on the government to end unfair restrictions that stop Britain’s best switching jobs or starting companies.
UK AI companies that have raised $5bn agree: our best should be free to start and scale. 🧵

We're excited to back @andocorporation's $20M Seed as @saradu and her team work to reinvent team messaging as agents increasingly work alongside humans.
Ando rebuilds the experience from scratch: agents as first-class teammates, not bots bolted on.

Is the old cybersecurity model breaking?
Our partner @shardul_shah joined @RebeccaBellan on @TechCrunch’s Equity podcast to discuss the permanent, resilient need for cybersecurity, and how enterprises should be thinking about it in the AI era.
Is the next era of cybersecurity machine vs. machine?
@shardul_shah of @IndexVentures tells @EquityPod that as AI-powered attacks get faster and cheaper, human-in-the-loop defense won’t be enough. The result could be an entirely new security stack.

Today I'm excited to share that @usefootprint has raised a $25M Series B, bringing our total funding to $45M.
Financial institutions are in an arms race with cartels and oligarchs.
The movement of illicit money globally has grown by $1.3 trillion since 2023, now sitting at $4.4 trillion. And bad actors have taken full advantage of AI’s capabilities: generating fake identities and shell companies faster than any team can manually review.
Yet, the work to combat financial crimes is still being done the old way - risk teams sifting through spreadsheets, PDFs, and disconnected tools one case at a time.
AI lets us reimagine this sector.
We're solving for this at @usefootprint by focusing on two things: time and memory.
→ Time: Percy runs your compliance program end-to-end in 1/10th the time, so your institution has extra eyes on every case, and your human analysts dedicate their time to the ones that truly matter.
→ Memory: Trust Fabric makes sure the grey area is removed and learnings are universal so your team (whether 5 or 500 people) catches more true positives and identifies fraud rings before they form.
With this raise, we're doubling down on the thesis that risk operations will be re-envisioned for the AI-native era. As AI increases financial crime in the global economy, we're building the defense system that can expand to meet and defeat it.
We're honored @QEDInvestors doubled down on their conviction, leading our Series B two years after leading our Series A. The same goes for those who have invested since day one: @lererhippeau, @indexventures, @BoxGroup, Operator Partners, Definition, and @animalcapitalco. And for new investors @am_mufg_jp, @commercevc, @lightbank, and @alumniventures.
To the Footprint team: this company would be nowhere without your belief in building a digital world full of trust. I thank you from the bottom of my heart for being on this journey with us.
To our customers: thank you for trusting us with your most important decisions. Your partnership is helping us build a better future for financial crime compliance.

Two years ago, Chris Ellis and Adam Stevenson sold us on their vision of replacing one-size-fits all group plans with individual health budgets.
With 5K+ employers now using @thatch_ai, we’re excited to partner again as they announce their $108M Series C!
Today, we're announcing @thatch_ai raised a $108M Series C at a $1B valuation from @thegp, @IndexVentures, @generalcatalyst, @a16z.
The idea we're betting on: healthcare serves whoever controls the dollar. For 80 years that's been the employer. We think it should be you.
Employers typically choose one health plan for everyone. We think there's a better model: give people a health budget and let them choose the insurance and care that fits their life. That is the idea behind Thatch.
ARR has grown nearly 7x in the last twelve months, and more than 5,000 employers now use Thatch. None of this happens without our team, or without the employers who believe that their people know what their families need better than they ever could.
We're building a healthcare system people love by changing how we fund it.

Europe doesn't have an energy shortage. It has a coordination problem.
Millions of homes generate and store power that mostly sits idle. We're proud to lead @nomosenergy's €20M round – backing the team building the operating system for Europe's energy transition, one home at a time.
