Census
The business, the turning points, and the decisions behind them.
01 / WHAT IT BUILT
What the company did
Census was a San Francisco reverse-ETL startup founded in 2018 by Boris Jabes and Anton Lazarev. Its platform let companies sync prepared, modeled data from their cloud data warehouses back into the operational tools where decisions are made — CRMs, marketing automation platforms, advertising platforms and support desks — making data available to teams without SQL or BI access. Census positioned itself as a composable customer data platform for 'data activation': syncing consistent, accurate customer data in real time to marketing, sales and product teams for personalized experiences and automated workflows. It served hundreds of customers across industries — including Canva, HubSpot and Uber — employed more than 50 people, and raised $80.3 million in venture capital from Sequoia Capital, Andreessen Horowitz and Tiger Global, including $60 million in 2022 at a reported $630 million valuation.
02 / Census FAILURE REASONS
Failure reasons
Census was not a failure in the traditional sense; it was a category pioneer that exited via a strategic acquisition. Its 'reverse ETL' category, however, faced structural headwinds that made independence harder: the value it created depended entirely on the cloud data warehouse, meaning warehouse vendors and data-integration incumbents could subsume the function. Fivetran — whose own customers had to bolt on a separate system to send data back into applications — was the natural consolidator: the companies had overlapping technology stacks, shared customers and go-to-market compatibility. Rather than fighting an expensive platform war against full-stack data vendors, Census's founders and investors chose the exit: on May 1, 2025 Fivetran announced it was acquiring Census (cash and equity, terms undisclosed) to build the first end-to-end data movement platform for the AI era. The Census brand was retired and integrated as 'Fivetran Activations.'
