ABOUT HELBIN RAPHEAL
Most early-stage founders I meet have the same problem: a strong product vision and zero clarity on how to turn it into something real. They waste months talking to agencies, hiring the wrong developers, or over-engineering an MVP that never ships. I partner with Seed to Series A founders as a Fractional CTO and Technical Co-Founder to turn product vision into scalable, production-ready systems without the overhead of a full-time CTO hire. 7+ years evolving from hands-on builder to equity-holding technical leader. Today I operate across HealthTech, SaaS, Real Estate Tech, and Pharma. What I bring to the table- Co-founded and architected Therapyway, a clinic management SaaS platform serving B2B and B2C therapists with secure video, appointments, and payments- Architected modular e-learning systems adopted across 25+ NHS clinical modules, accelerating course delivery by 30%- Led software engineering at Creative Capsule, improving UX metrics by 30% and reducing defects by 25%- Proven track record designing 0-to-1 architecture, design systems, and full-stack platforms (React, Next.js, TypeScript, PostgreSQL). My approach with founders is simple- Clarify: map your ICP, user journeys, and constraints into a focused product brief- Architect: design a pragmatic stack and delivery plan aligned with your runway- Ship: lead the build, manage the team, and get a testable MVP into users\' hands in 90 days. No recruiters please. If I need support hiring for my team, I will reach out. Thanks.
