One Madison Group
Investment firm that co-led Anello Photonics' Series B and participated in its Series B-2 round.
One Madison Group is a New York-based permanent-capital investment firm, founded in 2016 by Omar Asali. In 2024 it combined with Jonathan Soros and Salil Seshadri's JS Capital, with all three now co-leading the firm as partners. It deploys long-duration, flexible capital across public and private markets — acquiring controlling or significant ownership positions in cash-generative companies, alongside public-equities investments, private transactions, and minority co-investments — rather than running a traditional fixed-life VC fund. Its four-person Advisory Board includes Brad Gerstner (Altimeter), Ross Laser (Magnetar Capital), Narv Narvekar (Harvard Management Company), and Ravi Yadav (Newlight Partners).
