I Built an AI Startup Radar: 1100+ YC Companies on One Screen (2025 Trends Included)
I spent the last 2 months of evenings scraping and analyzing every Y Combinator AI startup from W22 to W25.

Why I built it
YC has become almost a pure AI incubator:
- 2023: 44% AI startups
- 2024: 72% AI startups
- 2025: around 80% AI startups
Everyone keeps asking the same questions:
- Which niches are already overcrowded?
- Where is YC actually betting money in 2025?
- Where should I definitely NOT build to avoid becoming the 152nd clone?
Most solutions out there are Excel files, random tweets, or hours of manual digging. I wanted one single place that shows the real, normalized picture of the market.
What the tool does
Explore page – 1100+ startups with smart filters
• Categories (Agents, DevTools, Healthcare, Legal, Infra, etc.)
• Crowdedness level (Few / Some / Many players)
• Batch filters (W22 – W25)
• B2B vs B2C
• One-liner + direct link for every companyTrends page – market share growth instead of raw counts
YC changes batch sizes every season, so absolute numbers lie.
Example:
S24: 10 crypto out of 200 = 5%
W25: 8 crypto out of 100 = 8%
Raw count looks like decline → actually +60% market share growth.
- Opportunities page – gap analysis + high-barrier warnings
Legal, Healthcare, Finance look empty from afar… until you remember 12-18 month sales cycles, FDA approvals, heavy regulation, etc.
Biggest 2025 insights I found
- AI Agents: from 7% (W22) to 29.2% (W25) = +157% market share
- Education exploded: +371% market share
- Enterprise Ops is dying: –54%
- Legal cooled off hard: –60% (looks like YC finally felt the barriers)
- B2B dominates completely: 85% of all AI startups (B2C only 11%)
Tech stack & key decisions
- Python for scraping and analytics
- Rule-based categorization (yes, not LLM – reason below)
- React + Tailwind + Vercel frontend
- Currently moving from CSV to PostgreSQL
Why rule-based instead of LLM:
- 100% deterministic (same input = same output forever)
- Fully explainable
- Processes 1100+ startups in under 1 second
- Zero hallucinations or drift
Who this is for
- Founders & indie hackers → validate your idea in 30 seconds
- Investors → instantly see where YC is putting money right now
- Job seekers → find the fastest-growing companies
