The smallest version that lets real users disprove or confirm the riskiest assumption in your product. If they pay with their attention, you have validation. If they pay with their wallet, you have product-market fit.
How do you validate a product before committing engineering budget?
Two-to-four week sprints that produce a clickable prototype plus interview synthesis from 8–12 target users. We come out with a build / kill / pivot recommendation and a written cost estimate for the build phase.
When does discovery hand off to build?
When the riskiest assumption is validated, the technical architecture is sketched, and the engineering team has read the discovery output. Discovery without that handoff is documentation theater.
Do you have product designers, or do engineers design?
Both, and they sit together. Senior product designers run discovery, information architecture and interaction design and own the design system; the engineers who will build the screens prototype alongside them, so what users react to is what ships. Splitting design into a separate studio makes sense at a 100-engineer org, not in a squad of five — which is why every Streaver engineer arrives with a product designer behind them.
02What we deliver
The shape of the work.
Capabilities
Discovery sprints (2–4 weeks, fixed scope)
Prototyping & validation
UX & interaction design
Design systems & product patterns (Tailwind, shadcn/ui, component libraries)
How it goes
1
Weeks 1–2Interview & observe
We map your users and your current product surface. Calls, screen-shares, no assumptions.
2
Week 3Synthesize & prototype
Clickable artifacts you can put in front of users — not slides, not Figma walkthroughs.
3
Week 4Validation + recommendation
Real users react to the prototype. We hand you a written build / kill / pivot recommendation with an engineering estimate.
After launch
The prototype validated. The design keeps evolving with the users.
Cadence
Design reviews run live with real users on each release; the design system grows with the product instead of drifting away from it — Prisma's founder sat in every review and live session.
Commercial shape
Fixed-scope discovery sprints, then design capacity inside the build retainer. No separate agency invoice for the design work.
Reviews
A usability check on every major release; a quarterly review of the patterns library against what shipped.
Hand-off
Design files, components and research notes are yours from the first sprint — Prisma took code, designs and knowledge together.
Product design at Streaver is a role inside the engineering team, not a studio you hand off to. Our senior product designers run discovery, set the patterns and the design system, and wire the screens up with the engineers who build them. Below: three shipped products, not mock-ups.
Senior product designers
Run the discovery interviews and information architecture, design the interactions and own the design system — embedded in the squad from kickoff to launch.
Engineers who prototype
Clickable prototypes are built in the product's own stack, so what users react to in week three is what ships in week six.
A team lead who owns the call
One named lead writes the build / kill / pivot recommendation and the engineering estimate that follows it.
