Fio · Apr 2026 to Jul 2026
I took an AI audio product to TestFlight, then ended it when demand did not justify the next investment.
I built the iOS experience and generation pipeline end to end. The beta worked technically, but did not validate urgency, retention, or willingness to pay.

Context
Fio turned saved articles, PDFs, newsletters, links, and screenshots into private podcast episodes grounded in the source material.
Mandate
As a solo founder and product builder, I was responsible for the product thesis, iOS experience, AI generation system, beta, and the decision to keep investing or stop.
Decision
The technical beta worked. The business case did not. A small waitlist and user conversations did not validate enough urgency or willingness to pay, free alternatives raised the bar, and the weekly format did not prove meaningful differentiation. I ended Fio in July 2026.
Execution
- 01
Designed and built the iOS journey from saved item to episode, including the home, player, and feedback flows.
- 02
Built and operated the generation pipeline across retrieval, scripting, evaluation, retries, and text-to-speech.
- 03
Created the landing page, waitlist, and beta feedback loop to test demand before investing further.
Outcome
Fio reached TestFlight and produced source-grounded episodes reliably enough for a technical beta. It did not produce sufficient evidence of demand, retention, or willingness to pay, so I stopped the product instead of treating a working demo as validation.
Scope note
I owned the product and assembled the system as a solo builder, using third-party models and services for parts of the infrastructure. The beta supports claims about hands-on execution and judgment, not product-market fit.
