How Fast proof works

You publish a landing page per smoke test, then bring the audience: social posts, ads, communities, and outreach from email lists you already run elsewhere. This app is the destination and the in-funnel email—not your list software.

Workflow

Start with your idea.
Tack on the questions you'd kill to know.
Publish and share.
Read the proof and move forward or not.

Questions and answers

That turns a simple waitlist into lightweight discovery: pricing bounds, must-have features, use cases, or objections—signal you can use to decide what to build, what to deprioritize, or who to interview next—without spinning up a separate survey tool.

What we do not do

We do not manage subscriber lists as a marketing platform: no list hygiene UI, segmentation, or a general-purpose composer for campaigns to your whole database. Building the list, storing it long term, and broadcasting outreach stay in the tools you already use; we are not a replacement for those.

What we store

For each test we keep signup email and related funnel data for the lifetime of that test so you can see who came in, who finished the continuation step, and how they answered your questions. That supports reporting and the private links in your transactional messages—not ongoing list management after the test ends.
