About OneSchema

OneSchema ( enables operations teams at SaaS companies to import customer CSV data 10x faster (demo). Our product is smart spreadsheet that makes data cleansing as simple as a few clicks. By configuring a no-code data template in OneSchema, our users can run an automated set of validations and transformations on their data, instead of having to hunt for and resolve issues one at a time. Operations teams use OneSchema when they need to repeatedly upload data to a system with a known schema (for example, setting up a new customer's data in a SaaS product or uploading a supplier inventory catalogs). Our vision is to automate the “long tail of ETL” processes that are managed by operations via CSV files over email.

We are backed by top investors including General Catalyst, Sequoia Capital, and Y Combinator.

We are a rapidly growing seed-stage company. Expect talented, motivated, intense, and interesting co-workers. Must be willing to work in-person from our office in San Francisco. Compensation will include substantial equity ownership.
