About

turbopuffer is a serverless vector and full-text search engine that rearchitects search around cheap cloud object storage instead of expensive RAM. By separating compute from storage and layering tiered caching on top, it lets companies index data that was previously economically unfeasible — storing data at roughly $0.02/GB versus the ~$1,600/TB/month of memory-bound databases. Founded in 2023 by former Shopify infrastructure engineers Simon Hørup Eskildsen and Justine Li, who spent eight years together scaling Shopify's database and compute layers, the company quietly became core search infrastructure for AI products like Cursor, Notion, and Anthropic. In production it handles 4T+ documents, 10M+ writes per second, and 25k+ queries per second. Famously capital-efficient, turbopuffer reached a reported $100M revenue run-rate and profitability on under $1M raised before taking an undisclosed round from Thrive Capital and angel Lachy Groom.

DailyDropout Take

turbopuffer is the rare infrastructure company that became critical plumbing for the AI era while staying profitable on less than $1M raised. By betting on object storage over RAM, Simon and Justine built search that's an order of magnitude cheaper — and quietly won Cursor, Notion, and Anthropic before most investors had heard of them.

Discovery signal: Powering search for Cursor, Notion, and Anthropic while profitable on <$1M raised; reported $100M run-rate with an undisclosed Thrive Capital round

What Makes Them Unique

turbopuffer is built natively on object storage rather than RAM, making search roughly 10x cheaper and letting customers index data that was previously too expensive to search at all — all while staying profitable on minimal funding.
