# Silimate

> Silimate is a Mountain View startup building an AI copilot for chip designers. Its AI-native tools find and fix functional bugs and power, performance and area (PPA) issues in digital chip designs, aiming to make hardware development move closer to the speed of software. Founded in 2023 by Ann Wu and Akash Levy, Silimate was the first EDA company Y Combinator backed (S23) and runs on-premise for Fortune 500 enterprises and chip unicorns building GPUs, CPUs and AI accelerators.

- **Founded:** 2023
- **Headquarters:** Mountain View, California, United States
- **Founders:** Ann Wu (Co-founder & CEO), Akash Levy (Co-founder & CTO)
- **Team size:** ~7-8
- **Products:** Silimate Copilot, On-premise / self-hosted deployment, Custom ML models for circuit characteristics
- **Notable:** First EDA company ever funded by Y Combinator (S23)., Reached profitability within roughly two years of founding., In production with multiple Fortune 500 semiconductor companies and chip unicorns.

## Products & services

- **Silimate Copilot** — An AI-native copilot for frontend digital chip designers that identifies bugs, traces root causes, generates patches, and analyzes RTL to improve power, performance and area (PPA). Integrates into existing design flows (including a VS Code / command-line interface) in under a day.
- **On-premise / self-hosted deployment** — Enterprise-grade, self-hosted deployment that keeps customer chip IP on their own infrastructure with no data egress, addressing semiconductor security and IP-protection requirements.
- **Custom ML models for circuit characteristics** — Machine-learning models trained to predict and analyze circuit characteristics, flagging inefficient logic paths and design tradeoffs for faster design convergence and closure.

## Achievements

- First EDA company ever funded by Y Combinator (S23).
- Reached profitability within roughly two years of founding.
- In production with multiple Fortune 500 semiconductor companies and chip unicorns.
- Reports 11x faster bug resolution and 70x faster PPA optimization for design teams.
- Founding CTO Akash Levy has taped out multiple chips, published 14 papers on circuit design, and holds pending EDA patents.

## Latest updates
