About Primary Venture Partners
Primary is the premier early stage venture firm working alongside founders to build unicorns like Alloy, Chief, Electric, K Health, Slice, Vestwell, and many more. The firm takes a low-volume, high-conviction approach—and devotes unreasonable resources toward making sure founders can succeed. With an Impact team that outnumbers investors 2:1,operational experts spend 100% of their time making hires, signing customers, and enabling future fundraising to supercharge growth. This partnership with top-tier founders makes companies in Primary’s portfolio 2x more likely to raise a Series A and 19x more likely to reach a billion-dollar-plus valuation—a third of Fund I companies are unicorns, less than a decade out. We’re always excited to meet 99th-percentile founders building in B2B SaaS, built world, fintech, healthcare, infrastructure, and supply chain. And while we have a home court advantage in NYC, we invest globally, at pre-seed through A.
