Great ideas rarely emerge from isolation

South Park Commons is a community of technologists ideating and validating what to build next. We believe this shouldn’t be done alone. Our members range from exited founders and highly-cited researchers to new graduates and first-time entrepreneurs.

Rebecca
I’ve lived inside the finance function my entire career - from ex-big 4er to in-house finance leader. I’ve built finance teams and systems from the ground up, led complex migrations, and battled the broken workflows that define today’s finance tech stack. I’ve seen the pain from every angle: as a service provider, a builder, and a user. Founders chase product-market fit. I am the validation of the problem, and the founder-market fit. I'm not just building software; I’m rebuilding the infrastructure I wish I had. As an ex-accountant turned founder, I’m on a mission to modernize the back office and deliver an all-in-one AI finance platform that replaces fragmentation with clarity, speed, and automation.
