Rockstar🎓
Top SchoolSeverin Ibarluzea is a founder and engineer with 14 years of hands-on experience building hardware-first startups and polished web interfaces from San Francisco. He cofounded and served as CTO at multiple startups including Seam (Series A) and WorkAround, and now leads tscircuit to rethink hardware development with software-like workflows. Technically versatile, he spans front-end React UI work (notably on popular tooling like Universal Data Tool’s image annotation) to backend systems and embedded electronics for low-power BLE and waveform generation. A Techstars alumnus and active open-source contributor, he brings product-focused engineering to data-labeling, storage, and grading systems. Colleagues describe him as a builder who combines product leadership with deep implementation skills across desktop, web, and embedded domains. He’s equally at home prototyping circuit-level hardware as streaming code for UI interactions, making him a rare bridge between hardware and full-stack software.
