The AI investment cycle has turned. Index Ventures cofounder Neil Rimer has said what a lot of smart money already suspects: the billions that went into AI over the past three years are starting to come back. Not someday. Now. That shift changes everything about how you should think about AI as an investor, a founder, or a builder in 2026.
Why This Moment Matters
Neil Rimer cofounded Index Ventures in 1996. The firm backed Dropbox, Figma, King, and Ramp before those bets looked obvious. When Rimer talks about where returns are coming from, people listen.
His read on AI is simple: we have moved past the faith-based investing phase. According to PitchBook, global venture investment in AI companies exceeded $110 billion in 2024, the largest single-year inflow the category has ever seen. That money had to go somewhere. Now it’s starting to find its way back through exits, acquisitions, and a growing list of enterprise contracts that actually generate revenue.
According to CB Insights, AI software deals in the enterprise segment grew 31% year over year in the first quarter of 2026. That’s not a prediction. That’s a billing cycle. The companies that survived the hype phase are now in the harvest phase. That’s exactly the kind of signal Rimer has spent 30 years learning to read.
The Contrarian Read Most People Are Missing
Most people are still asking the wrong question. They’re asking “is AI a bubble?” That question is three years too late.
The better question is: where does the money go when it comes back out?
I’ve watched this pattern play out before. The internet was “a bubble” in 2001. It was also the foundation of every business that mattered from 2005 onward. The investors who sat out the recovery while waiting for clarity are the ones who missed Google, Amazon, and Salesforce at prices that actually moved portfolios.
Rimer is telling you the AI recovery phase has started. That means the window to act like it’s still early is closing fast.
According to Bloomberg, AI-related mergers and acquisitions hit a record pace in the first half of 2026. Larger tech companies are buying AI startups not because they’re cheap but because organic development is too slow. That’s a seller’s market. And it’s a returns market for the VCs who backed the right teams early.
The rich versus poor mindset difference here is stark. Average investors are still reading headlines about AI layoffs and valuation markdowns. They’re waiting for the all clear. Operators and owners are watching the actual deal flow, seeing where Index Ventures and firms like them are moving their chips, and positioning ahead of the next confirmation.
Here’s what I find most telling about Rimer’s position: Index Ventures raised one of its largest funds ever in 2024. You don’t raise a massive fund into a dying category. You raise it when you see a long runway of deals ahead. If you’re building a startup in the AI space right now and you haven’t structured your business properly, you’re leaving money on the table. When deals start moving at the speed Rimer is describing, you need your legal documents signed and in order fast. A platform like signNow gets term sheets, investor agreements, and operating docs executed cleanly without slowing down the deal.
What This Means for You
If you’re a founder, this is your green light. Not because AI is guaranteed to work out, but because the acquisition market is active, the enterprise contract market is real, and the investor community that was burned by 2023 valuations has reset its expectations to levels that are actually fundable again.
If you’re an operator or an employee, start paying attention to where the exits are happening in your space. Your company’s next acquirer is probably shopping right now. Know your company’s value. Know what a deal would look like for you personally.
If you’re an investor with capital sitting on the sidelines, Rimer’s read is a warning shot. The window between “early” and “expensive” is shorter than it looks. The AI picks that seemed overpriced in 2023 are starting to look cheap compared to the revenue multiples they’re hitting in 2026.
For anyone thinking about starting an AI company or an AI-focused business right now: get your legal entity set up before you start signing deals or taking on partners. Inc Authority handles the LLC filing at no cost so you can spend your first dollars on the business, not on paperwork.
One practical note: the sector Rimer tends to focus on inside AI is infrastructure and vertical applications with clear unit economics. Not the broad “AI for everything” plays that burned people in 2023. Specific tools solving specific expensive problems in specific industries. That’s where the exits are happening first, and that’s where the money is coming back out fastest.
The Bottom Line
Neil Rimer has been doing this since before most AI founders were born. When he says the money is coming back out, believe him. The investors who wait for the press to confirm it will be reading about returns they could have had. The ones who move now get the positions that print. That’s how this has always worked. It’s how it’s working right now.
Frequently Asked Questions
Who is Neil Rimer and why does his take on AI matter?
Neil Rimer is the cofounder of Index Ventures, one of Europe’s top venture firms with a track record that includes Dropbox, Figma, and Ramp. He has been investing through technology cycles since the 1990s. His read on when a category shifts from inflow to outflow carries real weight because he has seen several of these cycles complete from start to finish.
What does “the AI money is coming back out” actually mean?
It means the venture capital that flooded into AI startups from 2022 to 2024 is now generating returns through acquisitions, IPOs, and enterprise revenue. The direction of capital flow has shifted from investing in AI to collecting on those investments. According to PitchBook, that $110 billion inflow in 2024 alone is now working its way back through the system.
Is it too late to invest in AI startups in 2026?
It depends entirely on the sector and stage. According to CB Insights, early-stage AI deals in vertical software are still priced at reasonable multiples in 2026. It’s late to catch the generic AI platform wave at seed prices. It’s not late to find strong vertical AI applications solving expensive problems with clear paying customers.
What kinds of AI companies are getting acquired right now?
According to Bloomberg, the most active acquisition targets in 2026 are AI companies with proven enterprise contracts and defensible data assets. Large tech firms are buying for distribution speed, not technology alone. Companies with a clear customer base and recurring revenue are the hottest targets in the current deal environment.
How should a startup founder prepare for an active AI exit market?
Get your legal and financial house in order before you need it. That means clean cap tables, signed agreements, and organized data rooms. Acquirers move fast when they want a company. Founders who aren’t ready lose deals or lose valuation during the due diligence scramble.
