Sisu (sisu.site)

Sisu is a founder-friendly incubator that partners with aspiring entrepreneurs from the earliest stages, often referred to as "day minus one." Our goal is to help founders maximize their potential by providing guidance and support through crucial decisions made during the first twelve months. This includes assistance with cofounder pairings, fundraising, and establishing a solid foundation for long-term value creation.

Sisu was founded by Ari Mir, a seasoned entrepreneur with over twenty years of experience in the technology sector. Ari has successfully founded three venture-backed companies, two of which generate over $100 million in annual revenue and employ more than 1,000 people.

At Sisu, we prioritize the founders' vision and autonomy. We do not consider ourselves cofounders and will not occupy board seats. After the initial twelve-month period, Sisu transitions into a more traditional advisory role, continuing to provide valuable support and guidance for the startup's ongoing success.
