Tier C
Early: a small team.
How much stands behind a tier: usage, who backs it, a confirmed line from its own site or paper, and a clear read on X. High with three of the four, medium with two, low otherwise.
- team 1-10
- went through Y Combinator Spring 2025
- in curated RL directories (3 pts)
How we got to tier C
- Adoption: team 1-10; went through Y Combinator Spring 2025. Tier C.
- On X: unclear, none buzz No move.
- In curated RL directories: 3 points, a floor of none.
- Confirmed: a line from its own site or paper places it.
A clear view on X moves a tier one step up or down; most entries don't move. How tiers work.
