Executive Summary
Propolis is a YC X25-backed autonomous QA testing platform that uses swarms of AI browser agents to test web applications like real users — no scripts, no setup. The core claims hold up: the product was live, had named production customers (Gumloop), and was compelling enough for Datadog (Nasdaq: DDOG) to acquire the company on January 28, 2026, within roughly one year of YC participation. The market is real and large ($450M–$857M SAM for AI-enabled testing tools today, growing at ~30% CAGR), but it is intensely crowded with at least six direct competitors pursuing nearly identical positioning. The single biggest structural fact for any investor reading this: Propolis is no longer an independent company — it has been acquired by Datadog, making this report most relevant as a retrospective on what the company was, and as context for evaluating the Datadog integration's strategic value.
