Designing a Wellness MVP for Biomarker-Driven Preventative Care

The impact

Wix site to a functioning, HIPAA-compliant MVP. Validated with an 18-member first cohort. The Sperity Score live, turning biomarker noise into one number members trust. A team that ships without a fractional leader.

Sperity Health went from a clinical vision with no product to a working concierge-health platform with 5 member personas, service blueprints, onboarding journey maps, and cross-functional delivery rituals across product, ops, and care. The 18-member cohort was the point, not a vanity count: it was the smallest group that could prove the Score and the onboarding actually worked before spending real money to scale them.

The product problem was hiding inside the audience

When I joined, Sperity had no functional product, no backlog, and no shared definition of "MVP." The founders had deep clinical expertise but no structure to guide hiring, development, or compliance, and they were explaining a complex concierge service through a basic Wix site.

The harder problem was one a generalist roadmap would have flattened. Sperity's members split into two opposite people: tech-savvy executives who wanted every biomarker reading, and health-anxious spouses who needed reassurance and simplicity. Build for one and you lose the other. On top of that, the raw inputs were a firehose, Whoop HRV and sleep, Signos glucose, lab biomarkers, fitness evaluations, all arriving as medical noise rather than meaning. So I started by narrowing: a working-backwards session to define success, then a sequenced MVP roadmap that made explicit what was in, what could wait, and what had to be tested first. I built 5 member personas (Intro Tier, Max Tier, Spouse, Interested, Corporate) to keep the whole range in view instead of designing for an average user who did not exist.

One number did the work of a dashboard

The highest-leverage decision was to anchor the entire experience on a single metric. Working directly with Sperity's physicians, I co-designed the Sperity Score, a daily 0-100 wellness number integrating Whoop, Signos, biomarker, and fitness data. The hard part was not the math; it was making one number that was clinically defensible to the physicians and legible to an anxious spouse at the same time, and that could absorb new data sources without changing meaning.

That choice paid for itself everywhere downstream. Instead of building separate views for the data-hungry and the data-averse, both got the Score as their front door, with depth available underneath for those who wanted it. It is the same lesson FLUXX taught in a different domain: in sensitive health products, the win is not showing more, it is giving people one trustworthy thing to act on.

Behind the Score, I mapped real care-delivery workflows (scheduling, diagnostic handoffs, patient communication) and used them to shape features, replacing manual calendars and back-and-forth texts with a centralized scheduling flow. I designed how sensitive results would be delivered and followed up on, treating the risk of confusion or harm as a first-order product constraint, not a polish item.

I also built the team. I referred Sperity's first product designer, who brought in the engineers who became the core dev team, then stood up the early rituals and delivered Product 101 coaching to the founders across MVP concepts, personas, research, OKRs, service blueprints, and prioritization.

What this built

• A product foundation built for clinical rigor and member trust. HIPAA-compliant infrastructure, care-aware UX, and a Sperity Score that turns complex biomarker data into something members can act on.
• A team that can ship without a fractional leader. Structured backlog, shared ownership across product, ops, and care, and rituals that replaced founder-driven decisions.
• A strategic foundation to grow from. Member personas, service blueprints, and onboarding journey maps that guide the product as Sperity scales past its first cohort.
