Single Family Office

Updated:

MaxsMaking Inc.

MaxsMaking Inc., the family office of Cards Against Humanity co-creator Max Temkin, has deployed over $45M into early-stage startups since 2019.

MaxsMaking Inc.

MaxsMaking Inc. was established in 2019 by Max Temkin, a co-creator of the breakout party game Cards Against Humanity. Temkin's wealth originates from the game's sustained commercial success and a series of spin-off projects — all bootstrapped and famously anti-corporate in posture. The office formalizes capital deployment that Temkin had already been pursuing personally, channeling liquidity events from the Chicago-based game studio and its sister projects into a structured investment platform now headquartered in New York. The firm operates with a generalist venture mandate, cutting checks primarily at the pre-seed and seed stages. Asset-class exposure spans direct equity in technology startups, media production ventures, and select real assets. Confirmed portfolio companies include the collaborative design tool Figma (secondary acquisition), the newsletter platform Substack, and the carbon-removal startup Charm Industrial. Temkin's approach favors founder-led, mission-driven companies — often those with strong community or open-source dynamics — and he has publicly discussed participating in rounds alongside firms like Andreessen Horowitz and Y Combinator. Geographic focus is US-centric but includes select international bets through relationships in the creator and tech ecosystems. Since inception, MaxsMaking has deployed over $45 million across dozens of portfolio companies, according to the firm's own disclosures. Temkin remains the sole investment decision-maker, supported by a lean team that draws on his network of Chicago- and New York-based operators and creatives. The office does not manage external capital. Adjacent structures include the Cards Against Humanity company itself — which continues to operate autonomously and occasionally co-invests or incubates projects — and Temkin's personal philanthropic activity, notably through direct giving and political fundraising, which is kept entirely separate from the investment entity. As of 2024, the firm confirmed a deployed capital base exceeding $45 million, with no external fundraising or fund-vehicle structure in place. MaxsMaking's structural distinction lies in its origin story: it is a single-family office built not on inherited wealth or traditional finance careers but on the proprietary, community-funded exit of a consumer product that deliberately rejected venture capital. This yields an investment posture unusually tolerant of long incubation periods, artist-led projects, and companies that resist traditional growth-at-all-costs models — a rarity in a venture landscape dominated by institutional LP pressure and fixed fund lifecycles.

Frequently asked questions

Who runs investment decisions at MaxsMaking?

Max Temkin, the founder and sole principal, makes all investment decisions. He co-created Cards Against Humanity and has been an active angel investor since before formalizing the office in 2019. The firm does not employ outside investment partners or delegate capital allocation to external managers.

How does MaxsMaking source its deals?

Deal flow originates primarily through Temkin's personal network of founders, technologists, and creative professionals built over a decade of operating Cards Against Humanity and collaborating on internet-native projects. The firm does not maintain a traditional inbound associate funnel, relying instead on direct referrals from existing portfolio founders and co-investors.

Does MaxsMaking take outside capital or operate fund vehicles?

No. MaxsMaking is a single-family office that deploys only Max Temkin's personal capital. It has never raised third-party LP commitments and has communicated no intention to do so, maintaining full discretion over investment pacing, hold periods, and exit timing without external reporting obligations.

What is MaxsMaking's relationship to Cards Against Humanity?

Cards Against Humanity, LLC remains a separate operating company based in Chicago. While Temkin retains an ownership stake and occasionally the game studio and the family office co-invest in or incubate shared projects, the two entities are legally and operationally distinct. The office was capitalized with proceeds from Temkin's exits and distributions from the game and its related ventures, not from ongoing operating revenue.

What investment stages does MaxsMaking typically target?

MaxsMaking concentrates on pre-seed and seed-stage companies, occasionally participating in later rounds for existing portfolio companies. The office has joined rounds alongside institutions like Andreessen Horowitz and Y Combinator, and has also acquired secondary positions in later-stage companies such as Figma.

Does MaxsMaking maintain a philanthropic or foundation structure?

Max Temkin engages in personal philanthropy and political giving, but MaxsMaking Inc. is not a philanthropic vehicle, and no private foundation is publicly affiliated with the office. Charitable activity is conducted personally by Temkin and is not commingled with investment activities.

What geographic regions does MaxsMaking invest in?

The firm invests primarily in the United States, with a concentration in New York- and Chicago-based companies. It has also made limited international investments, largely through personal relationships in the technology and creative communities that Temkin built through Cards Against Humanity and subsequent projects.
