Kaleb Barrett (ktbarrett): Semiconductors, Skoor 35 (n=3, confidence 0.7)

What they built

Barrett owns find_libpython, a Python tool that "finds the libpython associated with the current Python environment," with 22 stars and 8 forks [source]. The evidence classifies this repo as sector "other," not semiconductors [source].

He is listed as a committer on cocotb, a Python-based chip (RTL) verification framework with 2,544 stars [source]. He is also listed as a committer on Verilator, an open-source SystemVerilog simulator and lint system with 4,017 stars [source].

No company, product or startup he founded is in the evidence.

Record

Measured signals:
  • He made 44 commits in 90 days on cocotb [source]. The whole repo had 131 commits in that window [source].
  • He made 949 commit contributions in the last year [source].
  • He committed to both Verilator and cocotb in the last 90 days [source]. His commit count on Verilator is not in the evidence. The 657 figure is the repo total [source].

    • Profile:

  • His GitHub account was created in September 2016 [source].
  • He has 63 followers [source].
  • His profile lists Hudson River Trading as his company and Denver, CO as his location [source].
  • Papers, funding, co-founders and customers are not in the evidence.

    • Inference: 44 of 131 cocotb commits is about a third of recent activity. That suggests he is a central maintainer of an open-source chip verification tool.

    Inference: His listed employer is a trading firm. His semiconductor work may be open-source work alongside a job, not a venture.

    Why now

    Not in the evidence. Both semiconductor repos were pushed in October 2026 [source] [source].

    Inference: There is current activity but no stated company formation or commercial trigger.

    Unknowns

  • Whether he intends to start a company. Not in the evidence.
  • His role at Hudson River Trading and whether it involves hardware. Not in the evidence.
  • His share of Verilator commits. Not in the evidence.
  • Commercial users of cocotb or Verilator. Not in the evidence.
  • Education or prior roles. Not in the evidence.

    • Questions for the room

  • You made 44 of cocotb's 131 commits in 90 days. Which parts of the codebase do you own, and who decides its direction?
  • What did you contribute to Verilator, and how many commits is that?
  • Your profile lists Hudson River Trading. Is your verification work part of that job, and are you planning to leave to build something?

    • What would move the Skoor

    Raise: evidence of a company, co-founder or paid users built on his cocotb or Verilator work. Lower: confirmation that this is side-project maintenance with no plan to build a company.
