Most people saw AI startups. The real shift? AI as infrastructure.
~160 companies accepted. The signal was clear:
Agentic AI (~30%+) Not wrappers. Systems executing multi-step workflows autonomously. Replacing humans, not assisting them.
The vibe-coding edge (~25%) 1 in 4 companies had ~95% AI-generated codebases. AI wasn t just a tool; it was the development process. Speed became the moat.
Vertical > Horizontal Generic productivity lost to domain automation. Tighter workflows. Clear ROI. Stronger defensibility.
A lot of people read YC RFS Spring 2026 as a trend list. It s not. It s a signal of where work inside companies is quietly breaking.
Here s how this shows up in real teams:
Product teams YC references @Cursor , but the opportunity isn t coding faster. It s helping PMs synthesize interviews, metrics, and feedback to decide what to build next.
Finance and hedge funds Firms like Renaissance, Bridgewater, and D.E. Shaw won by systematising decisions. AI-native hedge funds push this further with continuous, machine-driven strategies.
This debate often gets framed as Should researchers use AI for literature reviews?
I think the real question is different.
Is it ethical to spend hundreds of researcher hours on mechanical work when that time could be spent advancing actual knowledge?
Think about a researcher spending an entire weekend searching papers, skimming irrelevant abstracts, copying citations, and fixing references. That s not insight or discovery. That s overhead.
As more teams build AI agents, search, and personalized feeds, one problem keeps surfacing. Not generation. Not model quality.
It s retrieval and ranking. Deciding what information should show up and in what order.
Most teams solve this by stitching together systems. Vector search for meaning. Keyword search for precision. Custom logic for business rules. Over time, relevance logic spreads everywhere and becomes hard to change.
