# Jamin Ball

> Jamin Ball is a Partner at Altimeter Capital and the author of Clouded Judgement, a weekly Substack newsletter with 87,000+ subscribers that tracks SaaS valuations, cloud earnings, and operating metrics for founders and investors alike. A Stanford-trained engineer who went from tech investment banking (Morgan Stanley, BofA) to venture (Redpoint Ventures) to growth-stage investing at Altimeter, Ball has built board seats at Airbyte, Clickhouse, dbt Labs, LiveKit, and Prisma, and coined the 'Rule of X' framework widely cited across SaaS finance circles. His writing bridges public market data with private company decision-making, and his 2024 essay on VC misaligned incentives prompted Bill Gurley to call it 'potentially the single most important issue for the entire venture capital landscape.'
