Velt
Velt is a San Francisco developer-tools startup that ships a full-stack SDK and APIs letting product teams embed contextual comments, notifications, presence, async recordings, huddles, and CRDT-based multiplayer editing directly inside their apps in days rather than months. Founded in 2020 by ex-Google product manager Rakesh Goyal and part of Y Combinator's W22 batch, Velt has evolved from a general collaboration toolkit into a review-and-approval layer where AI and humans review work together and nothing ships until a human approves. It is developer-first, enterprise-ready (SOC 2 Type II, HIPAA), and used by companies including Google, Pendo, HeyGen, and LambdaTest.
OpenWeb
OpenWeb is a social engagement and monetization platform that helps publishers own the conversation on their own sites instead of renting their audiences to social networks. Founded in Israel in 2015 as Spot.IM and now headquartered in New York, it pairs comment sections, live blogs and polls with AI moderation and in-conversation advertising. The company works with 5,000+ publishers, reaches more than 150 million monthly active users, and reached a $1.5B valuation after a $170M Series F in 2022.
