Accel

Accel is a leading venture capital firm that has invested in over 300 companies, including Facebook, Slack, and Dropbox. Founded in 1983 by Arthur Patterson and Jim Swartz, it's headquartered in Palo Alto and San Francisco, with additional offices in London and India. Accel's founders developed the firm's "prepared mind" investment philosophy — a disciplined, informed approach requiring deep domain focus. In 2000, it formed Accel-KKR with Kohlberg Kravis Roberts, an independently operated private equity firm targeting middle-market tech buyouts, alongside IDG-Accel, a China-focused joint venture with IDG Capital. The firm invests in enterprise, SaaS, and consumer companies across seed, early, and growth stages worldwide, with recent funds emphasizing AI and cybersecurity in Europe/Israel and expansion across India and Southeast Asia. Notable investments include Facebook, Atlassian, UiPath, Spotify, Cloudera, Tenable, 1Password, and Tailscale. Accel has raised substantial recent funds, including $650 million for early-stage Europe/Israel investing (2024) and another $650 million for India and Southeast Asia (2025). Its approach centers on identifying category-defining founders early and backing them with disciplined, long-term conviction.
