# David Bild

> David Bild is a technical co-founder and engineering leader at Resourcely, the cloud-security startup acquired by Anysphere (maker of Cursor) in July 2025. A Ph.D. computer engineer who once designed censorship-resistant networks, he has spent his career turning gnarly security problems into guardrails developers actually want to use - from overlay networking for IoT at Xaptum to secure-by-design Terraform blueprints at Resourcely. Post-acquisition he works on Fraim, an open-source, genAI-based application- and cloud-security tool. He builds from a cabin-adjacent base in Southwest Harbor, Maine, on the doorstep of Acadia.
