Value proposition
Prompt-to-silicon: agents handle chip design end to end, from architecture discovery through verification to tapeout. The company targets a GDS file in weeks rather than years by 2028.
Products and solutions
Autonomous chip-design agent infrastructure: a closed-loop system in which agents design, evaluate and revise computational systems using physical feedback, plus EDA tooling built for agents rather than humans.
Unique value
Claims verified designs about an order of magnitude faster than experienced hardware engineers using frontier coding agents on the same specs, with better power, performance and area. These claims are company-reported and unverified.
Target customer
Large foundation model labs (company-reported; no customers named) and, longer term, any company that needs custom silicon.
Industries served
Semiconductors / custom silicon, AI labs and AI hardware
Technology advantage
Closed-loop agent system with physical feedback. The team trained LLMs for RTL code generation and chip design at NVIDIA, and includes a former Intel custom silicon leader, former Kepler Computing ASIC lead, and former NVIDIA architects who led multiple tapeouts.
How they differentiate
Aims at fully autonomous end-to-end design through tapeout, with agent-native EDA tooling, whereas incumbents add AI agents to existing EDA toolchains and others focus on specific stages such as verification.
Main competitors
ChipAgents, Cadence (ChipStack), Synopsys (AgentEngineer / DSO.ai)
Key partnerships
Works with some of the largest foundation model labs (unnamed). Backed by Pear VC through PearX.
Major milestones
Founded 2025, PearX S25 batch with a Pear-led pre-seed (amount undisclosed), emerged from stealth with a $5.2M seed in Oct 2026.
Growth metrics
Company-reported eight-figure annualized run rate reached in under three months (unverified). Team of roughly 8-11 people.
Market positioning
Seed-stage challenger positioning itself as the next-generation chip design layer for AI labs building custom silicon.
Geographic focus
United States / global
