I'm looking to bring on a Technical Co-Founder / CTO to help build EXRT, a health & sports-tech startup focused on ECG-driven physiological and performance analytics for athletes and teams.
EXRT's direction is now clearly defined following practitioner-led validation and recent angel funding, with a larger upcoming raise planned once key technical milestones are delivered. This next phase requires a committed technical partner to own the architecture, data pipeline, and technical roadmap alongside me.
About EXRT
EXRT is a sports performance technology company using health-grade ECG data and AI to deliver actionable physiological insight for athletes, practitioners, and teams. The platform focuses on understanding internal response to training - performance, recovery, and adaptation, rather than diagnostics or consumer wellness metrics.
The Opportunity
EXRT is not building another activity tracker or generic dashboard. The focus is on:
- Continuous ECG-derived insight
- AI-driven interpretation of physiological response (performance & recovery, not diagnostics)
- Decision-support for athletes, practitioners, and teams
- Integration with existing performance ecosystems rather than replacement
Commitment & Compensation (important)
This is an early-stage co-founder role. Cash compensation is limited at this stage. Equity is meaningful and co-founder level. Recent angel funding provides runway. Further funding is actively planned following delivery of the next technical milestones. This role is suited to someone motivated by ownership, impact, and long-term value creation rather than short-term salary.
Technical Profile
You don’t need to cover everything, but strong experience in several of the following is expected:
- Backend engineering (Python preferred)
- Data engineering and time-series / biosignal processing (ECG experience highly advantageous)
- Applied ML / AI (classification, scoring, pattern detection)
- Cloud infrastructure (AWS, GCP, or Azure)
- API design and system architecture
- Experience working with complex, imperfect datasets
- Experience in health-tech, sports-tech, or regulated environments is a plus, but not a requirement.
What’s Offered
- Co-founder-level equity and long-term ownership
- Responsibility for technical strategy and execution
- Existing angel backing and active fundraising plans
- Direct collaboration with practitioners and end users shaping the product
If this sounds relevant or you know someone it should be in front of - feel free to comment or message me directly.
