Tier A

A

Scaling: 51 to 250 people, or $20M+ raised.

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.

How we got to tier A
  1. Adoption: team 51-100. Tier A.
  2. On X: unclear, low buzz. “Only one low-reach post mentions Parsewave, offering vague praise with no detail on dataset quality, customers, or results.” No move.
  3. In curated RL directories: 3 points, a floor of none.
  4. 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.
