The challenge
12 months stalled, and a founder on the edge.
Jacintha’s project sat frozen for over a year. A developer hired through her PR network produced nothing: no progress, no product, no path forward. She was navigating accelerator programs, fundraising pressure, personal setbacks and solo parenting at once, and the technical side of building a product had become a real source of anxiety and burnout.
I went into a deep, dark hole for about six months. You ask yourself: is this what I’m supposed to be doing? Is this where I’m supposed to be?
