A new AI startup launches every day, and the app store will not sort them for you. Tracker apps will. The right setup is not one app but a small stack: a searchable database for depth, alerts for speed, and a watchlist for the categories you care about. These are the five kinds worth installing in 2026, with the 513 company AIToolGuide database as the reference for what there is to track.
1. A searchable startup database app
Start with depth. The AIToolGuide app approach is a database first: 513 AI startups from the 2026 cohort, searchable by company, founder, category, batch and headquarters. When a name crosses your feed, you check it in seconds: who founded it, which batch, what it actually does. A tracker without this layer is just a news feed with better branding.
2. A launch alert app
Alerts trade depth for speed. A good launch alert app tells you the day a startup appears, grouped by category so 137 agent startups do not drown out the 8 data startups. Set alerts only for the categories you follow or the volume will train you to ignore them.
3. A category watchlist app
Watchlists are where tracking becomes research. Build one list per thesis: agents, devtools, robotics. The 2026 counts below show why the lists stay manageable: even the biggest category, vertical AI at 149, is a weekend of reading, and most categories run under 60 companies.
| Category | Startups in the 2026 database |
|---|---|
| Vertical AI Startups | 149 |
| AI Agent Startups | 137 |
| AI DevTools Startups | 58 |
| AI Robotics Startups | 51 |
| AI Infrastructure Startups | 29 |
| AI Security Startups | 25 |
| AI Voice and Audio Startups | 17 |
| AI Vision Startups | 10 |
| AI Data Startups | 8 |
| More AI Startups | 29 |
4. A batch tracker for demo days
Accelerator batches are launch events with dates. A batch tracker follows Winter, Spring, Summer and Fall intakes as they publish, which in 2026 meant 484 AI startups across four YC batches. If you only track one calendar, track that one.
5. A revenue board
The rarest and most honest signal: money. Only 12 of the 513 startups in our database report monthly revenue, all Stripe-verified. A tracker that surfaces revenue reporters separately, instead of mixing them into the launch noise, earns its place on the home screen.
One last setup note: put the database and the alerts on the phone, and keep the reading on the desktop. Tracking fails when it becomes a feed you scroll in bed; it works when it is a reference you consult with a question. Five apps, five jobs, no overlap.
