Commonstock is a social network that amplifies the knowledge of the best investors, verified by actual track records for signal over noise. Community members can link their existing brokerage accounts and share their real time portfolio, performance, and trades (by percent only, dollar amounts never shared). Commonstock is not a brokerage, but a social layer on top of existing brokerages helping to create more engaged and informed investors.

We've focused 100% of our effort so far on organic network effects and value-prop. As a result, a cult-like community has formed and is rapidly expanding itself thanks to finding product-market fit in beta. We're well capitalized and looking for teammates to help us harness the amazing energy of the self-directed investor.

Tech stack

Working at CommonStock

We are curious coders and builders who love investing and markets. We think we can change the world of investing using the APIs we're building. We geek out on markets/business and the tech behind all of it. If this sounds fun, you should join us.

Diversity and Inclusion

We actively support a variety of initiatives that aim at increasing workplace diversity. From external organizations to goals around the interview process, the only way to build a truly unique product is to have it built by a diverse group of individuals. That is our goal.

During each onboarding of a new coworker we have special orientations with different leaders within the organization. At the end of every sprint we host a Retroactive to talk about what went well and what could be improved. We also regularly host town halls and distribute surveys for feedback.

Employees at Commonstock are offered learning stipends and coaching from external parties to help further their careers.
