Build fast. Build right. A Vibe Coding Sprint that holds up past the demo.

You have a board meeting, a fundraising round, or an internal sign-off to win. You need something your audience can use – not a deck they have to interpret. We run focused 5-day sprints that deliver interactive prototypes built with AI and grounded in product thinking.

You need a working prototype. Here's what's getting in the way.

Most founders and CPOs hit the same wall before a major pitch or board review – the idea is clear internally, but translating it into something an external audience can actually experience takes longer than anyone budgeted for.
  • Your pitch is next month and you're still showing slides

    Investors and board members have seen hundreds of decks. A static presentation no longer communicates confidence in your product – it communicates that you haven't built anything yet.

  • Your internal dev team can't drop everything for a prototype

    Pulling engineers off the roadmap to build a demo is a trade-off most teams can't afford. And hiring externally for a short sprint feels like too much overhead for something that should take days.

  • You've seen AI-generated demos that fell apart under the first real question

    Vibe coding is fast. But without product thinking and design system discipline behind it, what you get is a prototype that looks impressive in a recording and breaks the moment someone goes off-script.

  • You don't have a clear path from prototype to actual product

    Building something fast is one problem. Knowing what happens after the demo – how the prototype connects to the real development track – is another. Most rapid prototyping shops hand you a file and disappear.

EXPLORE YOUR OPTIONS

One sprint. Three stages. Your call how far you take it

Some teams come in with a fully scoped idea and need five days to build it. Others need half a day of structured framing first. And some arrive at the sprint already knowing they want to take the prototype further. All three paths start here.

ASSESS

Problem Framing Session

Before writing a single line of code, we align on scope, user stories, and the exact goal of the prototype. Half a day of structured framing saves days of misdirected building.
Half dayFixed price

WHAT YOU GET:

  • Defined prototype scope

    A written agreement on what the sprint will and won't cover, so there are no surprises on day five.

  • User story map

    A structured view of who uses the prototype and what they need to accomplish, used as the build reference throughout the sprint.

  • Clear prototype goal and success criteria

    Concrete answers to "what does a good demo look like?" before anyone opens a code editor.

Wondering what scope alignment actually prevents during a sprint? Ask AI to walk you through it

BUILD

Vibe Coding Sprint

AI-driven development with Claude Code, real interaction flows, and design system alignment from day one. The result is a prototype that behaves like a real product – not a demo that needs a guided tour to make sense.
1 weekFixed price

WHAT YOU GET:

  • Working interactive prototype

    A clickable, tapable artifact your audience can explore without someone narrating what they're looking at.

  • Design system–aligned UI

    Every screen follows consistent components and tokens, so the prototype looks production-grade from the first click.

  • Documented AI workfloW

    A record of how the prototype was built, which prompts and tools were used, and how the setup can be extended.

  • Handover documentation

    Structured notes your development team can pick up immediately if the sprint moves into a full build.

SCALE

Prototype to MVP

A sprint is a starting point, not a dead end. If the prototype lands well, we have a clear path to move it into full AI product development – same team, same codebase, no handoff friction.
1-2 daysFixed price

WHAT YOU GET:

  • Sprint retrospective and build assessment

    An honest review of what the prototype validated, what it didn't, and what that means for the next phase.

  • Recommended next steps and scope

    A concrete proposal for moving from prototype to MVP, with timeline and team structure.

  • Direct path to AI Product Development track

    No re-onboarding, no knowledge transfer overhead. The same team that built the sprint continues the build.

Curious how the transition from sprint to full AI product development works in practice? Talk it through with AI

Got a deadline and an idea? That's enough to start.

If you have a pitch, a board review, or an internal demo coming up and nothing tangible to show yet – this is the right moment to reach out.

Vibe coding alone vs vibe coding with a team that's done it before

The gap between a vibe-coded demo and a vibe-coded prototype your investors can actually use is smaller than you think – and larger than it looks on screen.

ALONE

  • You ship something fast and it looks great – then someone goes off-script and the whole thing unravels

  • Every screen is slightly different because there's no design system keeping the AI output consistent

  • The prototype lives in a repo nobody else knows how to navigate

  • You spend day three rebuilding what you built on day one because the scope wasn't locked before you started

  • The demo lands well but there's no documented workflow, no handover notes, and no clear next step toward a real build

WITH A TEAM

  • Scope is locked in a half-day framing session before a single line of code is written

  • Design system alignment from day one means every screen looks and behaves like it belongs to the same product

  • Claude Code integration is documented so your team can extend the prototype after the sprint ends

  • You walk into the pitch with a prototype your audience can tap, click and explore without a guided tour

  • The sprint ends with a retrospective, a build assessment, and a direct path to MVP if the prototype lands

COMMUNITY

Where product teams figure out the AI era together

Product Builders | AI-Native is a community for practitioners building digital products in the AI era – run by Boldare, powered by 20 years and 350+ products of hands-on experience.

We regularly go live with guests from product, design, and engineering for honest conversations about what building AI-native actually looks like in practice. Written recaps, articles, and show notes from every session live on Substack.

What a decade of product building adds to a vibe coding sprint

Vibe coding is a method. What determines the outcome is the product thinking, design discipline, and delivery experience behind it. Boldare brings all three – and the evidence to back it up.
  • Production-grade AI evidence

    Boldare has 40+ live AI tools in production from internal and external engagements. When we say we know how AI-assisted development behaves under real conditions, we have the codebase to prove it.

  • Design system discipline built in

    Most rapid prototyping agencies skip design system alignment because it slows things down. We build it in from day one – because a prototype that looks inconsistent under investor scrutiny costs more than the time it would have saved.

  • A clear path from prototype to product

    A sprint with Boldare doesn't end with a handover file and a goodbye. If the prototype lands well, the same team moves it into full AI product development. No re-onboarding, no knowledge transfer overhead.

  • 300+ products built

    Every sprint is run by a team with deep product delivery experience behind it. That means better scoping decisions, faster problem recognition, and a prototype grounded in how real products actually behave.

Your prototype starts with one conversation

You don't need a fully defined brief to reach out. A deadline, a rough idea of what the prototype needs to do, and a sense of who needs to see it is enough to start scoping a sprint together.

Frequently asked questions about vibe coding

Technical and commercial questions about how the engagement works, who it's for, and what to expect at each phase.

What is vibe coding – and why does it matter for prototyping?

Vibe coding is an AI-first development approach where the primary driver of the build is a large language model – in our case Claude Code – guided by a developer who shapes direction, reviews output, and makes product decisions. The result is dramatically faster prototyping: what used to take weeks of traditional development can be done in days. The risk is consistency and quality control – which is why design system alignment and structured scoping are non-negotiable parts of how we run sprints.

What exactly does a "working prototype" mean at the end of the sprint?

What's the difference between a prototype and an MVP – and how do I know which one I need?
