What they do

fast program verification that checks code written by AI

How close to us

2, near

checks only: verifies code correctness, does not write the work; touches trust in AI code

Wedges

  • W1 Trusted 24/7 coding for small startup teams adjacent
L1 Company brain (knows the organisation) 0, none
L2 Agent team (runs agents, tools, approvals) 0, none
L3 Does and learns (finishes, checks, measures, updates the brain) 1, light

Their own description (from YC)

Theorem is training models that make program verification 10,000 times faster. Using verification as a feedback loop, developers have found zero-days in GPU accelerated code and cryptography implementations, and sped up code migration in legacy systems. If you have complicated code that needs to be correct and secure, sign up for our beta!
