Three years after Lululemon discontinued the Mirror hardware she built, Brynn Putnam has raised $20 million to test a specific theory about what went wrong — and what she is deliberately keeping the same.
Three years after Lululemon discontinued the Mirror hardware she built — widely reported in 2023 — Brynn Putnam has raised $20 million to test a single, specific theory about what went wrong — and what she is deliberately keeping the same.
The Series A, announced June 2, 2026, is led by Union Square Ventures, with USV General Partner Michael Mignano joining the company's board of directors in his first investment since joining the firm. The round also brought in angels Biz Stone, Tim Ferriss, and Scott Belsky, alongside existing investors including Lerer Hippeau, First Round Capital, BoxGroup, Adjacent, Coalition Operators, IRL Ventures, Metrodora Ventures, Patron, SV Angel, Twelve Below, and individuals Nabeel Hyatt, Josh Duyan, and Kevin Twohy.
But the money is the financing of a thesis, not the news itself. The news is the argument Putnam is making — that Board, the New York–based connected board game company she founded roughly three years ago, is the working theory of what she learned from Mirror, the connected-fitness startup Lululemon acquired for $500 million in 2020 and later wound down.
The connective thread between Mirror and Board is a willingness to build consumer hardware that argues for a category the market has not yet accepted. Mirror bet that a vertical screen in the home could be a fitness surface; Board is betting that a 24-inch touchscreen in a wood-finish frame, with proprietary "PieceSense" technology that recognizes physical game pieces, can be a game surface for the living room. There are no controllers and no logins, by design.
Putnam is also keeping the founder-led, design-first instinct that defined Mirror. Her co-designer at Board is Seth Sivac, a former World of Warcraft executive, signaling that the product is being built with the same care for tactile, in-person experience that Mirror applied to at-home fitness. The product was publicly unveiled at TechCrunch Disrupt in October 2025, about eight months before the Series A announcement.
The category claim is different this time. Putnam has taken to calling Board "together tech" — a deliberate counter to solo screen time and to the smartphone-as-default. In a market that has spent the last decade optimizing for individual feeds, Board is arguing that the living room still wants shared, in-person play, and that the right kind of hardware can make that frictionless.
The retention numbers Putnam is reporting suggest the bet is landing with the customers who have found the product. According to TechCrunch, citing company figures, 85% of Board's customers are averaging more than 30 play sessions per month, and the company says the device is in "tens of thousands" of homes, schools, hospitals, and restaurants across all 50 states. Those are company-supplied figures and should be read as attributed, not independently audited — but they are the numbers Putnam is using to argue that the category exists.
The biggest structural change is the platform layer. Alongside the funding, Board announced Board Studio, an AI-powered creation platform launching later in 2026 that the company says will let users build original games via natural-language prompts, with the company claiming an idea can move to a playable prototype in under an hour. That "under an hour" figure is a company claim, not a benchmark, and the natural-language scope should be treated as roadmap until the SDK ships.
The catalog at launch is also slightly unsettled in the public record: Engadget reported 12 original titles at launch in October 2025, while Forbes later counted 11 — a small discrepancy that should be resolved against the company's current press kit. Reported pricing has also moved: TechCrunch put the device at $399 in June 2026, against Engadget's October 2025 figure of $499 at launch and $699 standard retail, suggesting either a price drop or an early-bird-versus-standard split that readers should be told about before quoting a number in print.
USV's lead is itself a signal. Michael Mignano's decision to take a board seat on his first investment since joining the firm is a vote of confidence not just in the founder, but in the category thesis. The round also extends a long-standing relationship: Lerer Hippeau led Board's prior $15 million raise, the same firm that led Mirror's $3 million seed round years earlier. Putnam is being funded, in part, by the same investors who saw the first bet through to its exit and its end.
What does success look like for Board in the next 12 to 18 months? Putnam has framed it as a platform story as much as a hardware story: the device is the surface, but the SDK and the community-built games are the moat. The company's own site positions the product as a creator platform, not just a console.
If Putnam is right, Board becomes a different kind of consumer hardware company than Mirror was — one where the long-term value lives in the software and the creator ecosystem, and the device in the living room is the on-ramp. If she is wrong, the same structural problem that ended Mirror — a beautiful piece of hardware in a market that did not scale fast enough — will repeat itself.
The bet, this time, is being made in the open light of the prior outcome. The $20 million is the test capital for that test.
