Zero-to-one product delivery in D2C digital healthcare

How Welzo shipped a regulated D2C health MVP by cutting scope, aligning fast, and validating the core user journey before committing to build.

Zero-to-one product delivery in D2C digital healthcare

Welzo’s mission is to simplify healthcare by making testing, treatment and advice more accessible and affordable through smart, digital-first experiences.


Welzo is an early-stage D2C health startup operating in a regulated, high-trust domain, with ambitious timelines and limited capacity. The priority was to ship a credible MVP fast, without over-investing in the wrong product shape.

The challenge wasn’t a lack of ideas. It was deciding what mattered most, sequencing work under pressure, and getting something live that users could actually complete end-to-end.


The challenge

We needed to launch a minimum viable product quickly to validate demand, user behaviour and operational feasibility.

Constraints included:

  • Tight delivery deadlines
  • A large, pre-defined backlog
  • Regulatory and clinical considerations
  • High expectations around trust, clarity and conversion

The core risk was building too much, too early, without evidence.


Product approach

I stepped in with a hands-on product management role, owning prioritisation, flow definition, validation and delivery sequencing.

My focus was on:

  • Reducing scope to what was truly required for an MVP
  • Aligning the founder and team on clear trade-offs
  • Ensuring the product could support a complete, compliant user journey

Key actions:

  • Ran a prioritisation workshop using MoSCoW to cut the backlog down to a focused MVP scope
  • Mapped the critical end-to-end journey, from entry point through checkout and fulfilment
  • Defined milestones around learning and delivery, not just output

Solution

Rather than jumping straight into high-fidelity build, I created a low-fidelity prototype that mirrored a familiar eCommerce flow. This allowed us to:

  • Align quickly with the founder on product direction
  • Test assumptions around trust, clarity and progression
  • Validate the journey before committing engineering effort

The prototype became a shared artefact for:

  • Founder alignment
  • Early user testing
  • Engineering handover

This reduced rework and helped the team move faster with confidence.


Outcomes

  • A clear, prioritised MVP scope aligned to business and delivery constraints
  • A validated end-to-end user journey suitable for a regulated D2C health context
  • Faster decision-making by anchoring discussions in concrete flows, not opinions
  • A product foundation that could be iterated post-launch based on real usage

Result

Welzo launched successfully and quickly scaled to over 3.6 million customers. It was named the #1 Hottest Tech Scaleup in Europe and ranked as Forbes’ #1 Next Billion Dollar Startup in 2024.
