Profile
Stemma built a managed data catalog to help organizations discover, trust, and use their data assets.
Stemma, founded in 2020 and based in the United States, initially developed a managed data catalog to help organizations maintain a single source of truth for their data. The company raised a $4.8 million seed round in June 2021, led by Sequoia Capital, to build out its product. However, by June 2026, Stemma's corporate website (stemma.ai) is listed for sale on Afternic, indicating the company is no longer operating under that brand or has ceased operations.
No recent funding rounds, revenue figures, headcount, or customer names beyond the 2021 seed round are publicly available. The domain's sale listing suggests the company did not achieve sustained commercial traction or was acquired and its assets dissolved. The product portfolio appears to have been limited to the data catalog, with no evidence of pivots or new offerings.
Market position is unclear, as no competitors, market share data, or analyst mentions surface in current records. The company's trajectory appears to have stalled after its initial launch, with no public updates on product development, partnerships, or customer adoption since 2021. What is notable is the complete absence of any operational or financial disclosures after the seed round, contrasting with typical startup transparency.
The domain sale implies the intellectual property or brand may have been monetized, but no acquisition announcements exist. For a directory profile, Stemma represents a cautionary case of an early-stage infrastructure startup that failed to scale beyond its founding narrative.
