We view the power of a deep, engaged community of like-minded builders as our key differentiator, and work relentlessly to keep strengthening that unique fabric.
Everyone at Irregular Expressions is, first and foremost, an entrepreneur and a doer. We’ve slowly curated a group of technology executives and leaders, whose day job is to hire, grow and manage some of the most prominent engineering and product teams in the industry.
We’re moved by a shared drive to back outstanding founders, bringing cumulative decades of hard-earned engineering and product lessons to bear, both in reaching investment decisions, swiftly and with high conviction, and in working alongside founders to scale their companies, business, teams, and processes.
General Partner. Irregular Expressions was founded by Jean Sini, former CTO at Mint (sold to Intuit), Cadre (sold to YieldStreet), Fountain (sold to Porch), One Kings Lane, and angel investor in Canva, Treasure Data, FieldWire, People.ai, MindKick, Bison Trails among others. Jean launched IrregEx driven by repeated interest from founders in enrolling —early in their company's journey— the help of seasoned nerds.
