Overview
Greylock Partners is a venture capital firm that funds and supports the creation of technology companies. It invests money in startups and then works closely with founders, offering resources, mentorship, networks, and operational help to help them grow and scale.

The firm distinguishes itself with a long track record since 1965, having funded hundreds of companies and produced more than 150 IPOs, including notable names like Facebook, LinkedIn, Red Hat, Workday, Zipcar, and many others. The goal is to help founders build market-leading, sustainable businesses that achieve lasting impact and successful exits.

Company News
Snorkel AI has raised $350 million at a $3.5 billion valuation, nearly triple its $1.3 billion valuation from May 2023. The San Francisco-based data startup's annualized revenue has surged to $350 million from roughly $20 million a year earlier, driven by its data-as-a-service business launched in September 2023. Founded in 2019 by Stanford AI lab researchers, Snorkel shifted from selling software to supplying finished datasets and reinforcement-learning environments for AI training. The company uses an "agentic data development platform" combining human experts with specialised AI models to create and verify training data across fields including coding, law and medicine. Led by Insight Partners and S32, the funding round included Addition, Greylock and Wells Fargo. Snorkel will use the capital to hire researchers and engineers whilst expanding enterprise and government operations. The company expects to reach profitability this year.
