Swell Partners

New York preseed and seed venture firm that helps portfolio start-ups recruit strong teams

Swell Partners cover

About Swell Partners

Early hires often decide whether a young company survives, and Swell Partners builds its whole investment approach around that idea. It is a New York City firm that invests at the pre-seed and seed stages, and it describes its aim as helping portfolio companies assemble strong teams that give them an edge over rivals. The firm's older material called itself a next-generation venture firm with the character of a talent agency.

Investing and recruiting as one job

The firm's philosophy, as it states it, is that companies are won by people. It has built a network of sales, business development, product and marketing executives who have taken start-ups from their first days through to an acquisition or public listing. When a portfolio company needs a key hire, Swell draws on that network, including candidates who are not looking for work and would never answer a job advert. In its own words, it acts as an extension of the founding team in the area where founders most often need help, which is finding people.

How the founders came to this

The two founders, Rusty Ralston and Jay Patil, met in 2008 as early employees at a venture-backed start-up working on machine learning for talent assessment. That experience taught them how much a winning culture and the right recruits shape outcomes. The firm says they have been working together for more than fifteen years, starting with an early angel investment in the ad technology company Tapad, and that they helped grow the New York technology scene through investing and start-up recruiting.

A newer, narrower thesis

The current website describes a fund focused on four areas where founders are rebuilding critical systems with artificial intelligence: enterprise software that runs or secures important operations, space and defense, biology, and industrial work covering energy, robotics and manufacturing. The firm says it has invested in critical infrastructure since 2018. It looks for founders who have inside knowledge of an industry but think like outsiders, who move ahead of consensus, and who combine technical depth with commercial instinct.

Portfolio

The portfolio listed on the site covers a wide field. It includes space infrastructure, food waste reduction using data, remote-work and employment software, biomedical data, immigration software, security for companies adopting AI, night vision, three-dimensional mapping, therapeutics, defense systems, industrial AI models, warehouse robots, nuclear fuel recycling, financial guidance, marketing middleware, product subscriptions, corporate travel and access to medication. Older write-ups also name co-investors such as FirstMark, Union Square Ventures and Y Combinator alongside the founders it backed.
