The Problem

Coaches and creators get interest all day. DMs, profile visits, people asking how much they charge. And most of it goes nowhere because their link in bio is just a list of links. Visitors browse and leave and nobody knows who they were. The workaround is stitching together Linktree, Typeform, Calendly, a CRM and Stripe and then following up by hand, which almost nobody keeps up with. So leads they already earned just die.

The Solution

We make the link in bio work like a funnel instead of a menu. It asks visitors a few questions, branches depending on what they answer, captures the lead, books the call or sells the product with checkout built in. Then an AI agent does the heavy lifting. It builds the qualifying flow, scores how ready each visitor is and writes the follow ups. The user approves before anything sends. Takes minutes to set up and replaces the whole tool stack.

Why Now?

Audiences are already built, the creator economy did that part. But the monetization layer is still a static link page. Linktree has tens of millions of users and converts none of them. At the same time LLMs made lead scoring and personalized follow up cheap enough that a solo coach can now have what only sales teams could pay for.

What Makes This Hard?

The link page is the easy part. The hard part is a coach trusting an agent to talk to their leads. The scoring has to actually understand answers in context and the drafts have to sound like them or they will never hit approve. That only works if you own the funnel data underneath, which is why we built the flows, lead capture, CRM and checkout first. Anyone copying us has to start there too.
