Kater.ai is a data analytics platform founded in 2023 by Yvonne Chou and Robin Seitz through Y Combinator's Winter 2024 batch, based in San Francisco. Chou previously built data infrastructure from scratch as a data engineer at commercial real estate marketplace CREXi, while Seitz led engineering teams at Microsoft.
Instead of routing every ad hoc question to a data team's backlog, Kater's AI agent (branded Butler) auto-documents a company's tribal data knowledge into a searchable data map, then generates hypotheses about a business question, writes SQL queries to test them, and extracts insights from the results without a human writing the query by hand. The company reports reaching $330,000 in annual revenue while remaining self-funded outside its Y Combinator investment, a detail that signals real paying customers rather than a pre-revenue prototype.
Kater is built for company-wide use beyond a dedicated data team: any employee can ask a 'why did this happen' business question in plain English and get a validated answer. There is no published self-serve pricing; the product requires direct contact, positioning it as an enterprise data tool rather than a self-checkout SaaS product.
