Senior🎓
Top SchoolCesar Toscano is a founder and seasoned software leader with 15 years of experience building high-impact web and digital health products from startup to acquisition. Based in San Francisco, he currently leads Weller Labs to simplify creation and distribution of digital behavioral treatments, drawing on a track record that includes two FDA-cleared therapeutics. He combines hands-on engineering (full-stack TypeScript, React, NestJS, Postgres, GraphQL) with product and regulatory expertise—having defined quality processes for GDPR/HIPAA and software in a quality management system. Previously he scaled analytics and engineering teams at AVG, helped drive acquisitions at StackLead and Bitmatica, and led engineering for consumer health at Mahana Therapeutics. Cesar’s background in entrepreneurial finance from MIT and history of shipping production systems at scale reveal a blend of product-minded leadership and technical rigor. Less obvious: he repeatedly operates at the intersection of clinical compliance and rapid product iteration, preserving IP ownership while enabling clinical teams to iterate.
