# Validate before you commit a sprint. > Bixlow for product teams is an AI agent that builds working versions of an idea as code injected into the live site, so you can roll them out by percentage or audience and measure their impact before they reach the engineering roadmap. - Source: https://bixlow.com/en/solutions/product - Language: en - Publisher: Bixlow Before engineering spends two weeks on a feature, test it with real users. The agent builds a working version on your site, you roll it out to part of your traffic, and you know whether it belongs on the roadmap. - **Build:** Injected code, codebase untouched - **Rollout:** Gradual, by percentage or audience - **Backend:** Bixlow Functions, hosted by Bixlow - **Rollback:** Deactivate the workflow and it's gone ## Every sprint is a bet The roadmap fills up with features someone believes will work. You find out once they're built. ### You build to find out whether to build The only way to validate an idea is to put it in a sprint. If it fails, the cost is already paid. ### Engineering is the bottleneck Small experiments compete with tech debt and big features. They almost always lose. ### Ship to everyone or no one Without a gradual rollout, every launch is a leap of faith for 100% of your users. ### Opinions instead of data Priority debates are settled by gut feeling, because there's no real usage data for something that doesn't exist yet. ## How a product team validates with Bixlow The idea is tested on the live site, with real users, before anyone touches the codebase. 1. **Write the hypothesis.** A guided brief: problem, change, audience and metric. Attach whatever evidence you have and get a priority score. 2. **The agent builds a working version.** Components, logic and state as injected code. If it needs a backend, the agent writes a Bixlow Function. 3. **Roll it out to some users.** A percentage of traffic, a specific audience or an A/B test against the Original. You review it in the preview first. 4. **Decide with data.** If it moves the metric, it goes on the roadmap with evidence. If not, deactivate it and it's gone on the next page load. ## What a product team does with Bixlow Three ways to de-risk every sprint without asking engineering for time. ### Prototypes in production: A real feature, codebase untouched The agent builds the feature as a workflow: variables, actions, bindings and triggers injected into the page. - State in session, storage or the URL, plus derived variables. - Triggers on load, click, submit, variable change or action finished. - Version history with restore. ### Gradual rollout: From 5% to 100%, when you say so Serve the new version to a share of traffic or to an audience, and widen it once you're confident. - By percentage, by audience or as an A/B test against the Original. - Your own site attributes via window.bixlow.identify, like plan or logged-in status. - One click deactivates the published version and its tests. ### Bixlow Functions: Backend for the experiment, not the roadmap Server-side code that Bixlow deploys and runs, with encrypted secrets, called from your workflows. - Check stock or validate a coupon. - Send a lead to the CRM or talk to a payments or email API. - The agent writes it; you review it before publishing. ## The agent builds the test; product decides what makes the cut Describe the feature like a ticket. The agent builds the real thing, not a mockup. ### You decide - Which idea deserves validation before the sprint. - Who sees it, and what share of traffic. - The metric that confirms or kills the idea. - Publishing: nothing reaches your site without your approval. ### The agent does - Drafts the brief and the hypothesis. - Builds the feature with logic and state. - Writes the Function when a backend is needed. - Reads the results and sums up what you learned. ### A validation in Bixlow - **Idea:** Validate the coupon in the cart, before checkout - **Build:** Coupon field + a Function that validates it - **Audience:** Returning visitors - **Rollout:** A/B test ยท 20% of traffic - **Metric:** Checkout started ## Bixlow Studio: Need something bigger than an experiment? Bixlow Studio has engineers and designers who build on Bixlow when a test needs more than the agent. - Custom builds: components and product features. - CRM, payments or email integrations through Functions. - Goal setup for checkouts on an external domain. ## FAQ ### Does this replace our engineering team? No. It's for validating ideas before engineering builds them properly. What works goes on the roadmap with data; what doesn't is switched off without costing a sprint. ### What happens to the code when the test ends? Nothing is written into your codebase. Deactivate the workflow and the change disappears on the next page load. ### Can I target by plan or logged-in users? Yes, if your site passes that data with window.bixlow.identify. You can then use it as an attribute in any audience. ### Which plan includes Functions and A/B tests? Bixlow Functions and A/B tests are part of the Premium plan. Goals and analytics are on every plan; see pricing for the rest of the details. ## Validate your next feature this week Install the script, describe the idea to the agent and roll it out to part of your traffic.
