Single Family Office

401KARAT

401KARAT is Alex Baum's Miami-based family office, investing the proceeds from his 2021 exit of Cake into early-stage consumer and health-tech startups.

401KARAT

Alex Baum founded 401KARAT in 2022, directly following the 2021 sale of Cake, the sexual wellness brand he co-founded in 2018, to the Connecticut-based personal-care holding company High Ridge Brands. The exit, terms undisclosed, generated the primary capital base for the family office. Baum operates 401KARAT from Miami, Florida, maintaining the same entrepreneurial tempo that defined his operating career — board-adjacent, thesis-concentrated, and indifferent to fund-cycle convention. 401KARAT deploys capital across early-stage venture, pre-seed to Series A, with a pronounced tilt toward the consumer and health ecosystems Baum navigated as a founder. Asset classes include direct venture equity, select SPVs, and occasional fund commitments to emerging managers. Confirmed portfolio positions include sexual health platform Rosy and skincare line Dieux, alongside placements in fintech and enterprise software startups sourced through the alumni networks of Techstars and Y Combinator. Geographic focus spans the United States, predominantly coastal startup hubs, with opportunistic exposure in Latin America. The office remains lean, with Baum as the sole named investment principal and no known professional staff. In May 2024, Baum publicly co-invested alongside Serena Ventures and Will Smith’s Dreamers VC in a health-and-wellness round, signaling an active posture in the post-Dobbs femtech surge. Adjacent vehicles include Baum's ongoing role as a limited partner and mentor within the Techstars network, which functions as an informal sourcing pipeline for the family office, though no separate foundation or 501(c)(3) entity is publicly associated with the structure. The structural differentiator is the office's singular decision-making architecture — Baum is the investment committee, underwriter, and post-close advisor, making 401KARAT function more like an active angel syndicate backed by permanent capital than a conventional single-family office. No institutional capital has been raised, and the vehicle carries no external reporting obligations, allowing it to move at founder speed on deals that larger family offices or venture funds might process through multi-week diligence cycles.

Frequently asked questions

Who runs investment decisions at 401KARAT?

Alex Baum is the sole investment decision-maker. As founder and CEO, he originates, underwrites, and executes all deals without an internal investment committee. His operating background at Cake informs the office's concentration in consumer and wellness brands he can personally evaluate.

Where does the underlying wealth come from?

The capital base originated from the 2021 sale of Cake, the sexual wellness brand Baum co-founded in 2018, to High Ridge Brands. Forbes reported the transaction in 2021, though specific financial terms were not publicly disclosed.

How does 401KARAT source proprietary deal flow?

Baum sources primarily through his founder network, including the Techstars and Y Combinator alumni ecosystems where Cake was incubated. The office does not employ a formal sourcing team, relying instead on Baum's personal relationships with operators and fellow angel investors active in direct-to-consumer and health-tech.

Does 401KARAT participate in fund commitments or only direct deals?

The office prioritizes direct venture equity and SPV participations, but has made selective fund commitments, particularly to emerging managers whose deal flow overlaps with Baum's sector expertise. The balance skews heavily toward direct positions where Baum can add post-close operating value.

What investment stages does 401KARAT target?

The office invests from pre-seed through Series A, occasionally participating in later-stage rounds when a portfolio company raises follow-on capital. Baum's typical entry point aligns with his founder experience — the 12-to-18-month window where product-market fit is being established and an operator's lens is most valuable.

Is 401KARAT structured as a single family office or does it operate more like a venture firm?

401KARAT is a single family office with no external limited partners, but its investment behavior more closely resembles an active angel syndicate than a traditional family office. Baum makes decisions alone, moves at founder speed, and prioritizes the same consumer-health categories he navigated as an operator.

Does 401KARAT maintain philanthropic structures, and how are they separated?

No separate 501(c)(3) philanthropic foundation is publicly associated with 401KARAT or Alex Baum. The office's public footprint remains strictly investment-focused, with no known donor-advised fund or charitable trust structure.
