What is -1 to 0?

We coined the term -1 to 0 to describe our community's niche. -1 to 0 is both a time and a process. It's when you've left or are leaving your last major project but haven't fully launched what you're working on next. And it's the process of taming all the possible options you could pursue into the clarity of a single purpose. Whatever your next purpose turns out to be, the SPC community is here to help you get there.

Member Stories

Anurag Goel

How did Anurag Goel turn side-projects into a company?

A graduate of IIT in India and employee #8 at Stripe, Anurag joined SPC knowing only that he wanted to take on big problems. He built apps around healthcare, deep learning, and real-time communication, while helping other members with their projects. All this building and feedback revealed the opportunity for Render, a zero DevOps cloud platform Anurag founded out of SPC that has raised $26.75M and become one of the fastest growing tools in the developer ecosystem.

Ashton Eaten

A 2x Olympic gold medalist joined to figure out what to conquer next.

Kathy Qian

From the World Bank & ACLU to protecting democracy.

A Penn grad who did computational social science for the World Bank and ACLU while running a successful algorithmic trading side-gig, Kathy came to SPC to develop Code for Democracy. What started as a side project became a non-profit that provides tooling for journalists, researchers, and open-government advocates to automate political watchdogging.

Grey Nguyen & Ben Yang
Grey & Ben

SPC gave them the idea. Now they’re serving the community.

Part of the second Founder Fellowship cohort, Grey and Ben didn’t enter SPC with crypto in mind. But they kept hearing from SPC members how difficult it was for companies to deal with cryptocurrency. So they built Starlight, a one-stop-shop for companies to get started using crypto in minutes. Their first customers: the third Founder Fellowship cohort, which focused on web3.

Bilal Mahmood

A founder and policy wonk takes first principles to politics.

After serving as a policy staffer in the Obama Administration and later successfully exiting a startup he founded, Bilal joined us to explore how he could put his experiences to use for his community.

Jaclyn Rice Nelson & Noah Gale
Jaclyn & Noah

How community produces more communities.

When Jaclyn, an experienced operator and investor, and Noah, the founding sales hire at Gigster, met at SPC, they decided to start a company together.

This led to Tribe AI, a collective that connects independent AI experts with companies in search of AI talent.

These second-time founders knew: go slow to go fast.

Second-time co-founders Andrew and Praveen knew how hard the idea phase is after their previous company was acquired.

Gavin & Michael

Taking on a monopoly by making tax-prep less awful.

When they left Waymo to start a company together, Gavin and Michael had a core guiding principle: find a problem where consumers were being utterly failed and fix it. After joining the Founder Fellowship, they followed this principle right to tax prep. Column Tax was their solution.
