About
Stillwind builds AI tools for electrical engineers, centered on natural-language electronic-component search, cross-referencing, and simple circuitry. Its differentiator is translating requests into fine-grained specifications matched against a proprietary database of millions of parts, with Builder formalizing constraints into validated BOMs.
Market
Stillwind competes in electronic-component intelligence and AI-assisted electrical/PCB design, addressing the repetitive work of finding, comparing, cross-referencing, and validating parts. Octopart and Findchips emphasize broad component catalogs, distributor pricing, and inventory, while SiliconExpert emphasizes enterprise part intelligence, lifecycle, sourcing, and compliance; Zenode.ai is the closest AI-native comparison because it also supports natural-language, datasheet-grounded component search and alternatives. Stillwind differentiates through a proprietary datasheet-extracted database, hybrid semantic/parametric search, footprint-aware alternatives, and Builder’s constraint-based cross-referencing that aims to produce a semantically validated BOM rather than only a searchable parts or sourcing list.
Stillwind primarily serves electrical engineers, PCB designers, and hardware engineering teams in electronics and computer/electronic-product companies. The product is especially suited to lean or time-constrained design teams moving from a functional idea to component selection and a BOM; the evidence identifies engineering users directly but does not establish a specific company-size segment or procurement buyer.
At a Glance
Problem
Electrical engineers spend substantial time on repetitive, error-prone parts of hardware design, especially finding components, cross-referencing compatible alternatives, and handling simple circuitry. The core economic pain is wasted engineering time and slower design throughput: highly skilled engineers are pulled into component research and verification instead of higher-value design work. The main use case is rapidly identifying a suitable component or a footprint-matching replacement and moving from a design idea toward a bill of materials.
Product / Service
Stillwind is an AI-powered electrical-design platform that combines a ground-truth electronic-components resource with a copilot. Engineers can use natural-language prompts to discover components, find footprint-matching alternatives, or generate semantically checked boards; the workflow culminates in downloading a BOM and beginning the wiring process. Its Stillwind Builder is positioned as a design copilot that can take an idea to a BOM in minutes, and the product launched as a web-based public beta that was free during launch week.
Market
Stillwind competes in AI-assisted electrical and electronics design software, particularly component intelligence, electronic part search, BOM creation, and early-stage circuit or board design. The available company and Y Combinator materials do not name specific competitors, so the most defensible comparison set is the broader ecosystem of electronic-component databases, engineering search and cross-reference tools, and PCB or circuit-design copilots.
The company appears to be early-stage: it is listed as an active Winter 2025 Y Combinator company, with zero listed jobs, and its public beta was live and free during launch week. The available evidence does not disclose revenue, paid customers, or usage metrics, so traction is best characterized as an early product launch rather than demonstrated commercial scale.

Recent News
Stillwind announced Stillwind Builder, an AI agent that turns PCB design intent into a complete, verified bill of materials. Its public beta was live and free during launch week.
Stillwind launched Builder, a PCB design agent that uses search and mathematical constraint checking to assemble a validated bill of materials from an idea in minutes. The workflow formalizes requirements, searches component candidates, and detects violations or incompatibilities.
A December 2025 company listing identifies Stillwind as a Winter 2025 Y Combinator startup, while YC’s profile lists it as founded in 2024, active, and based in Zürich. The sources provide accelerator and seed-funding context but do not disclose a funding amount or a separate financing announcement.
