About Graham Weaver
Graham Weaver is the founder and managing partner of Alpine Investors. Alpine is a San Francisco private equity firm that invests in software and services businesses. Alpine describes itself as a people-driven firm, and its site lists Weaver as founding partner.
Weaver has more than 20 years of private equity experience and is a lecturer at Stanford Graduate School of Business. Crunchbase lists him as a Stanford GSB alumnus. Alpine's site puts the firm at $18.9 billion. He writes about leadership and personal development at grahamweaver.com.
Little is public about Weaver's personal angel investing. Crunchbase shows one personal investment, Idilio. It also shows one founded organization, Alpine Investors. No other angel investments, check sizes or fund vehicles are listed publicly.
The Lounge deals desk lists Weaver in the Idilio seed round of $5.5M, announced in June 2026. Idilio is a Latin American microdrama platform that uses AI in content production. Press coverage says the round was led by Jeffrey Katzenberg's WndrCo. The coverage I found names other investors but does not name Weaver, so the Crunchbase and Lounge listings are the basis for his participation.
On AI more broadly, Alpine's summary of a My First Million podcast appearance says Weaver thinks most AI rollup strategies will fail.
Weaver's personal angel focus is not public. His Idilio investment was at seed stage, in AI-enabled consumer media. Through Alpine, he invests in software and services companies. Alpine's work is private equity, so it is a different practice from early-stage angel investing. No personal check size or geographic preference has been published.
