Wei-Wei Wu

Wei-Wei Wu is co-founder and CEO of Momentic, an agentic quality platform for web and mobile tests. With Jeff An he started the company after watching engineering teams trade velocity for brittle Selenium and Playwright suites.

Nashi, Density, and hating tests

Wu was founding engineer at Nashi (acquired by Density) and later a staff engineer on product reliability. An came from testing leadership at Robinhood and quality work at Retool. Their YC Winter 2024 Launch post jokes that they "dreaded testing so much we founded a company to do it for us," then describes plain-English steps, self-healing selectors, and CI integration.

Seed to Series A

Momentic raised a $3.7M seed with FundersClub, General Catalyst, and YC, then a $15M Series A led by Standard Capital in 2025. Customers listed in public materials include Notion, Bilt, Quora, and Webflow. Product marketing leans on triage agents that explain failures, not only record-and-replay.

On quality as a shipping unlock

Wu frames QA as something that should accelerate releases rather than throttle them. The company's Series A posts talk about a "verification layer" for software - agents that keep coverage alive as UIs move - which matches the founder pair's reliability backgrounds.
