AI & Machine Learning: write the cheque.
AI/ML is the most expensive thing to build and the fastest thing to fund.
Scope: Foundation models, post-training infrastructure, inference, evals, agents, copilots, retrieval, fine-tuning, applied AI verticals.
TL;DR, AI & Machine Learning
AI/ML is the most expensive thing to build and the fastest thing to fund.
Quadrant: Write the cheque , High cost-to-build, high deal-velocity. The market rewards capital and rewards it fast, sourcing inside the pre-fundraise window matters more than picking the right sub-niche.. Data refreshed weekly.
Build-vs-invest scoring measures engineering cost-to-velocity ratio across GitHub organizations: a sector where high commit velocity co-occurs with low cost-per-commit is a build signal (founder-addressable); high velocity with high cost is a fund signal (capital-intensive, institutional). All scores are derived from the SSRN panel dataset and update with each weekly data refresh.
Cost-to-build
78/100
Even a wedge AI product now carries a meaningful compute bill, a token budget, and a hire-fast pressure that turns indie-mode plans into Series A pitches inside one quarter.
Deal-velocity
96/100
Pre-fundraise signal-to-announcement lag in AI/ML is the shortest of any sector we track, usually 4-8 weeks rather than the cross-site median of 6-12.

The honest version
What the score is really saying.
Engineering acceleration in AI/ML is so loud it pre-empts almost every other signal on the site. Velocity is the highest of any tracked sector, rounds compress to days once the right curve is visible, but the capital required to keep up with frontier costs makes this a category where most founders should be writing cheques, not code. The buildable wedge here is the niche eval, the niche tool, the niche agent, never the base model.
If you are building
The indie playbook.
Fits when: You have unfair distribution (an existing audience, an existing customer base, or proprietary domain data).
- 1Pick a single workflow inside one vertical, not a horizontal copilot.
- 2Ship against the cheapest viable model and an obvious eval; defer fine-tuning until usage proves a moat exists.
- 3Lock in a paid pilot before raising, AI/ML rounds without revenue evidence increasingly stall.
If you are funding
The investor playbook.
Fits when: You can underwrite frontier-cost burn and you have follow-on capital for the bridge nobody talks about at seed.
- 1Use the engineering-acceleration signal as a pre-news watchlist; respond inside 14 days of the trigger.
- 2Underwrite the post-training infra layer and the eval layer separately, different moats, different multiples.
- 3Avoid generic chat wrappers; verify a domain-data or distribution moat exists before the cheque clears.
Frequently asked questions.
Why is AI/ML in the fund quadrant if everyone says it is bubbly?▾
Bubbliness is a price story. The build-vs-invest framework is about velocity and cost: AI/ML deals genuinely close faster than any other sector we track, and the indie cost-to-build is higher than it looks once compute and salaries are honest. Both facts can be true even if entry valuations are stretched.
Can a solo founder still ship a useful AI product?▾
Yes, but only in narrow, distribution-anchored wedges. The mistake is reading 'fund quadrant' as 'do not ship'. It means 'do not ship horizontally without capital'. Vertical, distribution-led wedges remain the highest indie hit-rate inside this sector.
Same quadrant, different sectors.
Fintech
Fintech rewards capital and patience, not weekend builders.
Climate Tech
Climate tech is finally fundable software, but only the software half.
Cybersecurity
Cyber is the most reliable mid-velocity fund quadrant on the site.
Data Infrastructure
Data infrastructure is fund quadrant, but the indie wedge inside it is the best on the site.

When the verdict isn’t enough
You read the quadrant. Now you want the names.
The free Monday email tells you which way the wind is blowing. If ai & machine learningis the call you’re weighing this quarter, two faster moves: pull the live teardown on this one sector, or watch every sector week over week so you see the team pulling ahead before it shows up in someone’s deck.
Pressure-test one sector
€7
One sector, one teardown, one sitting. The same read your analyst would spend an afternoon on, who’s shipping like they’re about to raise, and who just looks busy. Cheaper than the coffee you’d buy to ask around.
Test one sector, €7 →Watch it move every week
€49/mo
The standing dashboard across every sector we track, so the team that quietly doubled overnight lands in front of you, not in front of the partner who beat you to the term sheet. The deck lags the work by 21 to 47 days; this is where you spend that head start.
