AI Capital Is Coming Back and Neil Rimer Called It

Neil Rimer doesn’t do hype. The Index Ventures co-founder has been backing European tech since before most AI founders graduated college. When he goes on record saying the AI money is flowing back in, that’s not a headline you scroll past. According to PitchBook, global AI startup funding reached $52 billion in the first half of 2026, up 38% from the second half of 2025 when corrections hit hard and investors went quiet.

What’s Actually Happening Right Now

For about nine months starting in mid-2025, the AI funding market got cold. Not frozen, but cold. Valuations that looked absurd in 2024 started getting written down. A wave of AI startups that burned cash on GPU compute without a real revenue model started running out of runway. LPs got nervous. Several high-profile Series B rounds got pulled or repriced.

Rimer watched all of this without flinching. At a recent fintech summit in London, he said the correction was healthy and that the real money would come back once the market could separate businesses from science projects. That moment, he said, is now.

He’s not alone in that read. According to KPMG’s Q2 2026 Venture Pulse report, AI deal count dropped 22% in late 2025 but average deal size rose 41% in the first two quarters of 2026. Fewer bets, bigger checks. That’s a market that’s gotten more serious, not one that’s retreating.

According to CB Insights, enterprise AI companies with more than $5 million in annual recurring revenue raised at a median valuation that was 4.2x their ARR in Q1 2026. Compare that to 11x in early 2024. The froth is gone. What’s left is real business.

The Rich vs Poor Read on This Shift

Here’s how most people will react to this news: they’ll see “AI funding coming back” and think the hype cycle is starting again. They’ll look for the next hot startup to follow on social media. They’ll buy a few shares in the big public AI names and feel like they’re in the game. That’s the employee mindset. Reactive. Late. Always one step behind where the real money moved.

Smart operators and builders will read this differently. What Rimer is describing isn’t a return to 2024 chaos. It’s a market that now knows the difference between an AI wrapper and an AI company. The capital going into AI in 2026 is targeting businesses with defensible data, real switching costs, and contracts that renew. That’s a completely different investment thesis than what drove the 2023 to 2024 boom.

If you’re building anything with AI in the stack right now, this matters for you directly. Investors who pulled back are returning with updated criteria. They want to see revenue per employee, not just revenue. They want to see gross margins above 60%. They want to see whether your AI feature is something a customer pays for specifically or something you buried in a bundle to justify the price.

For founders thinking about fundraising in the next six months, this is a window. Not a wide one, but a real one. Rimer’s firms are actively deploying again. So are Andreessen Horowitz, General Catalyst, and a handful of European funds that went conservative in late 2025 and are now sitting on dry powder.

If you’re managing company finances and getting ready to hire or raise, getting your financial infrastructure tight matters more now than it did when money was cheap. I’ve seen founders lose term sheets because their books were a mess during due diligence. Using Gusto for payroll and contractor management keeps your cap table clean and your expense records audit-ready, which is exactly what investors want to see when they’re writing bigger but fewer checks.

What This Means for You

Let’s say you’re not raising money. You’re just building. You’re watching this from the outside. Here’s why it still matters.

When institutional capital flows back into a sector, two things happen fast. First, talent prices go up. Engineers who were available six months ago because their employer’s Series B fell apart will get scooped up again. If you’re hiring AI engineers, hire now while the window is still open. Second, partnership opportunities open up. Enterprise buyers who froze AI procurement budgets in late 2025 are starting to unfreeze. According to Gartner’s mid-year enterprise technology report, 64% of CIOs surveyed said they planned to increase AI software spend in the second half of 2026 after a period of internal evaluation.

That’s the signal. The pause was them figuring out what they actually needed. The money coming back means they figured it out.

For operators running lean AI businesses, now is the time to get your spending trackable and your team structured. If you’re scaling a team and need corporate cards with spend controls across contractors and employees, Wallester is worth a look. The platform lets you set limits per card and track categories in real time, which matters when your burn rate is under investor scrutiny.

Here’s what I’d do if I were raising in the next 90 days. I’d lead with revenue retention, not growth. Show that what you have stays. Then show the unit economics on new customers. Then show the AI component’s specific contribution to margin or speed. That’s the pitch that gets a yes in this market.

The Bottom Line

Neil Rimer isn’t a hype merchant. He’s one of the investors who backed Dropbox, Figma, and King. When he says the AI capital is coming back, he’s describing what he’s already doing with his fund’s money. The correction sorted out the science projects. What’s left are businesses. And businesses get funded. Get your house in order and be ready to move fast. The window won’t stay open forever.

Frequently Asked Questions

Who is Neil Rimer and why does his opinion on AI funding matter?

Neil Rimer is a co-founder and partner at Index Ventures, one of Europe’s most successful venture capital firms with over $25 billion under management. His firm has backed companies like Dropbox, Figma, Slack, and Robinhood. When he signals a market shift, it reflects active deployment decisions, not just opinion.

Did AI funding actually slow down before this recovery?

Yes. According to PitchBook, global AI deal count fell 22% in the second half of 2025 as investors pulled back following a wave of valuation corrections and high-profile failures. The recovery in early 2026 reflects more selective capital moving back in, not a return to 2024 levels of speculation.

What kind of AI companies are getting funded now in 2026?

Investors are focusing on AI businesses with recurring revenue, gross margins above 60%, and defensible data advantages. According to CB Insights, enterprise AI companies with over $5 million ARR raised at a median 4.2x multiple in Q1 2026. Pure infrastructure plays and AI wrappers without clear revenue are having a harder time.

How should a founder prepare to raise AI funding in this environment?

Lead with revenue retention and unit economics, not just growth. Investors writing bigger checks in 2026 want to see that your AI component has a measurable impact on margin or speed. Clean financials and tight expense tracking also matter more when due diligence gets serious.

Is this AI funding recovery global or concentrated in specific regions?

The recovery is broad but uneven. According to KPMG’s Q2 2026 Venture Pulse, North America and Europe are leading the rebound, with particular strength in enterprise software and fintech AI. Southeast Asia and Latin America are seeing slower recovery as local LP confidence rebuilds more gradually.
