Nicole Kelner
Product Manager
Indie developer who has built 2 apps and instrumented them end-to-end in Mixpanel, running onboarding conversion experiments to find the flow that turns installs into paying users. Before that, nine years of product work as a cofounder, COO, and chief of staff, scaling new and existing products, including a K-12 education company I helped grow from one location to five nationwide, 1,000 students, and $1M in revenue before it was acquired.

Zero to One
From communicating the complex topics within the IRA to building apps, I am passionate about creating products that provide people with real value in their daily lives. I specialize in taking products from zero to one, working in ambiguous environments and bringing structure.

Case 01
The IRA guide
Every home electrification incentive, drawn onto the part of the house it pays for. 250,000 impressions, adopted by local governments.

Case 02
Free Time
iOS, live on the App Store at 4.8 stars. Instrumented end to end, then iterated on what the data said.

Case 03
Unplug OS
iOS, in beta and launching 2026. Device access gated on charging state, specified across 24 screens.

Case 04
So You Want to Work in Climate

Case 05
The Coding Space
K-12 company plus an open-source IDE. One location to five and $1M in revenue, then acquired. The one I built with a team.
