# CEO / Co-Founder

About Sisu Sisu is a founder-friendly incubator dedicated to partnering with entrepreneurs from the earliest stages, often referred to as “day minus one.” We guide founders through the first twelve to eighteen months, helping with co-founder pairings, MVP development, fundraising, and more, to establish a foundation for long-term success. Founded by Ari Mir, a serial entrepreneur with over 20 years of experience, Sisu is built on the principles of grit, humility, and an unrelenting drive to create impactful companies. Ari’s ventures include two companies generating over $100 million in annual revenue, employing more than 1,000 people. https://www.sisu.site/ The Opportunity We are seeking visionary and resourceful business leaders to become CEO co-founders. If you are accepted into Sisu, you’ll collaborate with other exceptional founders, receive mentorship directly from Ari, and work toward building your own startup. This is a rare opportunity to start something meaningful with unparalleled guidance and resources. Note: This is not a traditional job-it’s an opportunity to be the business co-founder of your own startup. About You (Business/Operational Focus) We are looking for top-t
