AlphaSights

Expert Network

CompareAdded

AlphaSights is a global expert network founded in 2008 in London by Max Cartellieri and Andrew Heath. The firm connects decision-makers at investment funds, consultancies, and Fortune 500 corporations with domain experts for primary research. Unlike competitors that emphasize static database size, AlphaSights positions its custom-sourcing model — recruiting experts fresh against each brief — as a deliberate differentiator. The firm has grown to 2,000+ employees across nine offices worldwide, raised $400 million in September 2024 at a reported $4.2 billion valuation (led by Carlyle and TA Associates), and increasingly invests in AI-augmented workflows via AlphaGPT, AlphaGraph, and AlphaNow.
