Descriptiontext

CommonStock is a private social investing platform founded in 2017 and headquartered in San Francisco that targets retail investors in stocks and crypto. The platform's core product connects users' existing brokerage accounts to enable real-time sharing of investment insights, performance transparency, and social discussion of strategies, with differentiated features including brokerage account integration, copy-trade functionality, and ranking of investment strategies. By building on top of — rather than replacing — incumbent brokerages, CommonStock positions itself as a social and analytics layer over the retail brokerage ecosystem, addressing pain points around opacity in investment performance and isolation in retail investing decisions.

The go-to-market motion is community-led and self-serve via a direct digital platform distributed globally to individual consumers. The business model is described as subscription recurring, though pricing is not publicly disclosed and no named premium-tier customers or product modules are documented in available sources. The company has raised roughly $34.7 million in cumulative disclosed funding across a 2016/2018 pre-seed, a $9.7 million round in August 2020 co-led by Floodgate and QED Investors, and a $25 million Series A in October 2021 led by Coatue with participation from Bill Ackman and a syndicate of venture firms. Founded by David McDonough (CEO) and Michael Smith (Director of Engineering), CommonStock operates with a headcount of 11-50 employees.

No AI/ML capabilities, API offerings, named enterprise customers, certifications, patents, or post-2021 funding activity are documented in the available data, which constrains visibility into current scale and product roadmap. The platform's strategic moat relies primarily on network effects among retail investors and the data advantage derived from verified brokerage-linked performance, while the absence of disclosed monetization scale or recent operating signals limits revenue and growth assessment.
