Alex Pall, partner at Mantis VC and one half of Grammy-winning duo The Chainsmokers, sat down with Heather Hartnett, CEO of Human Ventures, at Global Alts New York 2026. The conversation walked through how Pall and Drew Taggart turned a music platform with 150 shows a year into a venture firm now writing checks alongside Sequoia and Founders Fund. Pall talked about the partner architecture, why founder access is the only metric that matters, and what the consumer pendulum looks like from a celebrity LP base that includes Tom Brady, Mark Wahlberg, and DJ Khaled.

The celebrity venture playbook has a credibility problem, and Mantis VC has spent eight years engineering around it. Pall told the room that he and Taggart started by asking experienced investors and founders what they wish they had known before raising a fund. The answer that kept coming back was that brand opens the first door, but founders only return calls for partners who actually help. Mantis built backwards from that. Pall and Taggart bring distribution and culture signal. Jeffrey brings six startups of operator reps. Milan brings the traditional venture training. Pall described it as putting the Avengers on a cap table.

How Mantis VC underwrites the celebrity venture playbook

The firm runs a thesis around the consumer pendulum. Pall argued that after a decade where capital chased pure software and AI, attention is rotating back to consumer brands that earn cultural relevance the slow way. The Mantis network on tour, in arenas, and across social platforms gives the partners a real-time read on which products actually break out.

The point Pall hammered is that the celebrity venture playbook only works when the celebrity is one input among several. Mantis writes concentrated checks, runs portfolio support like a platform team, and refuses deals where the founder wants a logo more than a partner. That filter cuts most of the inbound. It also explains why the firm has been able to co-invest into competitive rounds at Sequoia, a16z, and Founders Fund pricing.

What founders actually want from the celebrity venture playbook

Hartnett pressed on the access question. Pall said the most underrated value the firm delivers is talent introductions — specifically to operators who would not take a cold recruiter call but will take a meeting from someone who just played their wedding. He described a portfolio CEO who closed a head of growth in 48 hours through a Mantis intro after six months of pipeline work elsewhere.

The conversation turned to fund size. Pall said Mantis intentionally caps its funds where the math still favors concentrated bets. The team writes a small number of meaningful checks per year, doubles down on the winners with reserves, and avoids the index-fund failure mode that has caught a lot of platform-heavy firms.

The signal Mantis VC reads that other firms miss

Pall closed on what he called the only metric that matters: are you in the best deals. Everything else at Mantis works backward from that North Star, and the partners screen every internal decision against it. The deal that gets passed up because the founder is great but the market is wrong is still a pass. The deal that the partnership debates for two weeks because the founder is unproven but the product breaks something real is still a yes. That discipline is rare. It is also what separates the venture funds that compound from the ones that index.
