Visibl Semiconductors (YC Winter 2026). Skoor 40, n=4, confidence 0.8
What they built
Visibl describes itself as a custom-silicon design partner for hardware companies, starting with power electronics [source]. It calls itself "AI-native" and says it cuts ASIC development cost and timeline on mature nodes [source]. The pitch is to take v1 boards built from off-the-shelf parts and fold those parts into custom silicon for v2+ volume [source]. It says it manages architecture, design, verification, fabrication, packaging and production [source]. It lists target markets ranging from data-center power and motor drives to EV charging, solar, grid and appliances [source].
Whether any chip has been designed, taped out or shipped is not in the evidence.
Record
Measured signals (n=4, all from the YC directory):
Founder names, technical backgrounds and prior chip work are not in the evidence. Funding, customers and revenue are not in the evidence. No code repositories or job listings were captured.
Inference: the Skoor rests on YC acceptance and team size alone. It does not reflect any founder or technical record.
Why now
The company's stated reason is that hardware teams scaling to volume need lower cost, smaller size and fewer supply constraints than off-the-shelf parts allow [source].
Inference: the bet is that AI-assisted design lowers custom ASIC cost on mature nodes enough to reach mid-volume hardware companies that could not justify a chip team before. No market data in the evidence supports or tests this.
Unknowns
- Who the three people are, and whether any of them has taped out a power IC.
- Whether the "AI-native" claim refers to proprietary tooling or to standard EDA flows.
- Which fab and packaging partners they use.
- Which one of the many listed markets comes first.
- Any signed design engagement.
Questions for the room
- You say AI cuts ASIC cost and timeline. What is the baseline, and what has your tooling done on a real design so far?
- You claim the full path through fabrication and packaging with three people. Who on the team owns analog and power design, and who handles fab and packaging?
- You list markets from data-center power to heat pumps. Which customer has given you a v1 board to convert, and on what terms?
What would move the Skoor
It would rise with named founders who have shipped power silicon, a completed tapeout, or a signed design customer. It would fall if no silicon has been designed in-house and the AI claim describes outsourced design services.
