Tier D
Very early: no disclosed funding or accelerator, and little presence on X.
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
- no disclosed funding, under 1k followers, little X discussion
- in curated RL directories (3 pts)
On X · unclear, low buzz, from 1 post about Tacit Labs in the last month
Only one modestly engaged post, essentially a recruiting pitch, mentions Tacit Labs; there is no visible discussion of its evals or customer results.
How we got to tier D
- Adoption: team 1-10; no disclosed funding, under 1k followers, little X discussion. Tier D.
- On X: unclear, low buzz. “Only one modestly engaged post, essentially a recruiting pitch, mentions Tacit Labs; there is no visible discussion of its evals or customer results.” 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.
