About Atomic
Atomic is a venture studio that co-founds companies rather than only funding them. Founded in 2012 by Jack Abraham, the firm generates ideas internally, tests them with its own research and operating staff, then recruits founding executives to run each business while retaining a large founding stake. A shared team supplies engineering, design, recruiting, growth marketing, finance and legal support, so a new company can reach a first product and first customers without assembling those functions itself. That model produces a small number of company starts each year, with Atomic involved from incorporation through the first institutional rounds rather than entering at a priced seed. Companies built or co-founded through the studio include Hims & Hers in consumer health and telehealth, Bungalow in residential rentals and co-living, Found in banking and bookkeeping for self-employed workers, Homebase, Replicant in voice automation, and Exowatt in energy hardware. The firm invests through its Atomic Labs funds; commitments disclosed across Funds II through IV total roughly $728 million, capital used both to seed internally created companies and to follow them into later rounds. Atomic began in San Francisco and filed its 2022 Atomic Labs IV offering from Miami, Florida, reflecting the move of its base to South Florida while it keeps Bay Area staff and companies. Because Atomic originates the companies it backs, its process screens ideas and operator candidates rather than inbound pitch decks, and the people it recruits are typically operators who want to run a company without originating the concept. Its concentration is in consumer health, fintech, marketplaces and software categories where a founding team can be staffed quickly and incumbents are slow to respond.
Investment Thesis
“Co-founds companies by pairing entrepreneurs with ideas, resources, and capital to build startups from inception.”
Leadership Team
Jack Abraham is managing partner and chief executive, and he is the named executive officer on every Atomic Labs fund filing from 2017 onward. He is the constant in a studio model where the firm supplies the idea, the capital and part of the founding team rather than buying into rounds others assemble.
Chester Ng is general partner, first appearing on the Atomic Labs III filing in 2021, and Nat Disston is partner. The leadership group is deliberately weighted toward operating functions rather than deal flow: Justin Rubbo is chief financial officer and operating partner, Atticus Honore is chief legal officer and operating partner, Luke Sophinos is an operating partner, Phillip Liu is principal and head of healthcare, and Sharon Winter and Michael Stenclik are principals. Atomic describes everyone on the team as a builder, working in wireframes, code or ideas, which is the staffing consequence of co-founding companies instead of only funding them.

Fund History
Atomic raises against its Atomic Labs entities, and the filings show a firm that consistently oversubscribes its own targets. Atomic Labs II, L.P. filed a $100 million offering in October 2017 from San Francisco and amended a year later to $148.4 million sold, with Jack Abraham named as executive officer. Atomic Labs III, L.P. filed a $250 million offering in November 2019 and amended in March 2021 to $262.5 million sold, adding Chester Ng as a named officer. Atomic Labs IV, L.P. filed a $300 million offering in April 2022, this time from a Miami address, and amended in May 2023 to $317.2 million sold. Across the three vehicles that is roughly $728 million in disclosed commitments.
Two parallel vehicles run alongside the main funds, Atomic Labs Partners III, L.P. registered in California in 2021 and Atomic Labs Partners IV, L.P. registered in Florida in 2023, the standard structure for carrying co-investment and affiliated capital next to a flagship. The registered address migration from San Francisco on Funds II and III to Miami on Fund IV tracks the firm's move of its principal office.
