Design Partner to a first-time founder. I took a raw "Tinder for motivation" idea to a validated, defined AI-product MVP.

DoPamp started as a "Tinder for motivation" idea from a first-time founder. I came in as his design partner, and together we validated the concept from scratch: I ran a 300-person research study across three user segments, built behavioral personas, and we pivoted the product model twice (from peer matching to community to AI agent) before defining an MVP ready for development. Along the way I stopped three high-risk directions before they cost time and money. The project is currently paused, but the strategic foundation and product direction are solid.
The founder's original vision: People want to work out but lack motivation. The solution: connect "Ups" (people who'd been through the same struggle and overcome it) with "Downs" (people who need a push right now). Like Tinder, but for finding a motivation buddy. Community-driven, with gym partnerships for revenue later.
What was actually broken about this:
The concept was emotionally compelling but had critical product problems:
What research revealed: 300 people surveyed across 3 segments:
The key finding: motivation doesn't fail because people lack a buddy. It fails in a specific moment, usually post-work, at home, when willpower is lowest.
They don't need a person. They need an immediate intervention at the right time.
My role: Design Partner. Not just designing screens. Co-defining the product, challenging the founder's assumptions with data, and making strategic decisions together about what to build and what to kill.
The team:
The dynamic: This was a first-time founder who was cautious about spending on a process that might not deliver. My job was to earn trust in the process by being transparent: showing the data, making decisions together, and being honest when an idea needed to change.
No wireframes, no screens, no brand. First question: is this idea real? I designed and ran surveys for 3 user segments with different question sets. 300 responses total. This was the foundation for everything.
From the survey results I built behavioral personas that mapped motivation patterns, barriers, and what actually helps. The personas told a different story than the founder expected.

The data showed the original Tinder-matching model had problems. I brought this to the founder with specific evidence, not opinion. Together we iterated on the model.
Every major decision was made together. I proposed, he challenged, we decided. This wasn't me delivering a brief. It was a partnership.
When the developer joined, I handed off generic screens first (registration, login, profile, messaging) so building could start while I worked on the core feature. That kept development moving without blocking on the hardest design problems.
The founder was attached to the Tinder-style matching. It was his original vision. Telling him "this won't work" required more than opinion. I showed him:
We explored alternatives together: small profile photos instead of full-screen, gender-separated feeds, even narrowing to a single tight-knit community as a beachhead. But ultimately the Tinder model didn't survive the data.
The founder wanted an animated avatar or character as the AI interface. I pushed back: it feels childish and reminds people of WhatsApp sales bots. I argued for a clean, minimal chat interface inspired by ChatGPT and Claude. People already know how to interact with those. Just adapt the colors and tone for fitness and motivation.
This was a real disagreement. He felt the avatar would create personality and connection. I felt it would undermine credibility. We discussed it, I showed references, and he came around.
The founder had big ideas: nutrition tips, psychological matching, community challenges, trigger detection near fast-food spots, gym-proximity notifications, integration with gym check-in chips. Each idea was valid on its own. My job was to say "yes, but not now." We scoped to the core: SOS button, AI diagnosis, 3 micro-solutions, verify, reward. Everything else was Phase 2 and beyond.
The project paused for personal and budget reasons. It was self-funded, and runway got tight mid-build. This is a real risk with early-stage founders, and it's part of the story. The work we did (validation, personas, product architecture, MVP definition) is still valid and waiting.
The pivot: from peer matching to AI agent.
As AI matured during the project, we realized the technology could deliver what the community model couldn't: immediate, personalized intervention without needing other users.

The core flow (SOS model):

Smart features (designed, not yet built):

What was deliberately cut from the MVP:
The honest result: The project is paused, but the strategic work (validation, personas, product definition) is intact and waiting. Sometimes the most valuable thing a design partner does is prevent expensive mistakes before they happen.
Three bad ideas were stopped before a single line of code was wasted on them.
Working with a first-time founder who is spending carefully requires a particular kind of trust. You can't just show up with a pretty deck. You have to show the work, share the data, make decisions together, and be honest when a beloved idea needs to die. That is what "design partner" actually means. Not "here's your mockup." It's "here's why we're not building that."
