Digital health startup Geneva, Switzerland

The CTO a startup couldn’t hire just yet

This digital-health startup had a great idea, early customers and a small junior tech team — but no senior technical leadership at the helm. For twelve months, we played the role of CTO: architecture, hiring, health-data security, and fundraising preparation.

The context

Fast growth, no technical compass

The founders came from healthcare, not technology. The product was growing fast, but every major technical decision kept being postponed — and the debt piled up, threatening to slow everything down.

  • Non-technical founders, architecture decisions postponed.
  • Technical debt slowing down every new feature.
  • Sensitive health data, high compliance requirements.
  • Investors demanding serious technical due diligence.

The role

A CTO on every front

Rather than one-off advice, we took on the responsibilities of a technical director, at the pace the startup needed.

Architecture & scalability

Re-architecting the platform to absorb growth.

Hiring & team

Defining roles, technical interviews and upskilling.

Security & compliance

Protecting health data and applying best practices.

Product roadmap

Technical prioritization aligned with business strategy.

Reliability & performance

Monitoring, CI/CD and platform stability.

Investor due diligence

Preparation and support during fundraising.
