Starting point
Ben Nevile (CTO) and Julien Smith (CEO), approached me with a vision: to develop a service facilitating asynchronous connections between students and teachers, providing accountability partnerships and support for personal goal pursuits.

As former leaders at Breather, we secured $2M in initial funding, with Nicolas Bichon joining as our iOS leader. Six months of strategic experimentation led to a pivot that captured A16z's attention.
