UX fixes that ship as fast as you do.

Point Buildbox at your software product. It finds the UX friction across every user flow, tests the fix before your users hit it, and hands your engineers a reviewed PR.

High impact382 users affected

New users reach the dashboard in its zero state with no content and no clear action, so they are left guessing what to do next. Most stall here and drop before completing a single meaningful action.

Proposed fix

Give the zero state a primary CTA and a sample project, so new users always see a clear next step.

Say hello to Buildbox

Every product and growth team knows there's friction somewhere in its flows. But finding it, building alternatives, and reading the results rarely beats the rest of the roadmap.

Buildbox runs that loop nonstop across the flows that matter most, and hands your engineers a reviewed PR when a change wins.

Ship the winner your way. A test-backed PR your engineers approve, or a ticket routed to Linear, Jira, or Slack.

Find the friction in hours,
not weeks.

Each agent carries a real user's intent, like the enterprise admin wiring up SSO or the trial user rushing to first value, and moves through your product the way that person would.

They stall where your users stall. So you catch the friction the day you ship, not the week the data finally trickles in.

Analytics are reactive and A/B tests are inefficient. Buildbox catches friction before either, without waiting on data to make product decisions.

Catch it before your users do.

Buildbox surfaces friction the moment it appears, before it costs you a single signup.

Your questions, answered.

Who is Buildbox for?

Buildbox is for product and growth teams improving important user journeys, from signup and onboarding to checkout, upgrade, and activation.

If improving those flows still means manually reviewing sessions, guessing at fixes, and waiting on engineering cycles, Buildbox is built for you.

What does Buildbox actually do?

Buildbox crawls your product, maps the important flows, and runs vision-based agents through them to find where users are likely to stall.

Then it tests better versions and turns the best fix into a reviewed pull request, ticket, or Slack-ready report with the evidence your team needs to act.

How is this different from PostHog, Amplitude, or Mixpanel?

Analytics tools show where users dropped off after real users hit the flow. Buildbox can test flows before or alongside live traffic, explain the product friction behind the drop-off, test better versions, and turn the best fix into something your team can review and ship.

How is this different from Pendo or Appcues?

Pendo and Appcues help you add guidance on top of your product: tooltips, tours, banners, and onboarding layers.

Buildbox focuses on fixing the product itself. If a user needs a walkthrough to complete a core flow, we would rather find the confusing screen, test a clearer version, and ship the fix.

Are the tests run with real users or agents?

Agents first, users when it matters.

Buildbox runs vision-based agents grounded in UX research and your product's user-intent data. They inspect each screen with specific goals and personas, decide what to do next, and flag moments where real users are likely to stall.

When a fix is ready, you can validate it with real users, an experiment, or a controlled rollout.

What access does Buildbox need?

For an audit, Buildbox can start with a URL and test credentials if the flow is behind login.

For deeper use, Buildbox can connect to analytics, feedback, issue trackers, and a scoped GitHub app. Code changes are opened as pull requests for review. Buildbox does not merge or deploy changes unless your team explicitly configures that.

Is our data used for training?

No. Your data is not used to train foundation models. Audit access is read-only, and pilots run on scoped permissions with subprocessors you approve.
