Sequoia Capital backs founders from the earliest stages of company formation through growth. Arc is its entry point for pre-seed and seed teams.
Arc is Sequoia’s twice-yearly open call for pre-seed and seed founders. The programme includes a four-day intensive focused on customer understanding, product-market fit, team building and growth strategy.
Sequoia can invest before a business has revenue or even a settled product idea. Its Arc materials describe backing NVIDIA as a founding team and Wiz before its initial idea was fixed, illustrating the company-formation stage at which a founder can engage.
