Arthur Patterson

Arthur Patterson is a co-founder of Accel Partners and one of the most senior figures in Silicon Valley venture capital, writing $250k+ checks at seed and Series A in digital health and health IT software, with no AI flag. His personal angel activity at this stage of his career is highly selective and tends to follow conviction-led personal relationships rather than programmatic deal flow. A personal check from Patterson is a category-defining signal that pulls top-tier institutional capital and brings deep, multi-decade enterprise software pattern recognition. Founders building B2B healthcare software with category-defining ambition, platforms targeting multi-billion-dollar enterprise outcomes, or companies where his Accel-era network and senior credibility add meaningful value are the only realistic fit. He is the wrong audience for biotech, devices, consumer wellness, AI-heavy plays where the AI is the entire thesis, or anything that doesn’t credibly target multi-billion-dollar outcomes. Cold outreach is essentially non-viable; founders should invest in warm introductions through Accel portfolio CEOs, senior Sand Hill Road investors, or the broader enterprise SaaS founder community. LinkedIn is a viable channel only with a credible mutual connection. Diligence will be metrics-fluent and senior-investor-style, so come with a clear product, traction story, and articulated category-defining narrative. Founders without obvious access should redirect energy.
