About Nat Turner

Nat Turner built Flatiron Health after his cousin's leukemia journey led him to focus on fixing how oncology data is collected and used, developing a distinctive data-first approach that structured real-world clinical data from cancer centers to power both patient care and drug development. He maintains an unusual dual identity as both a leading health-tech founder (Flatiron's $1.9B acquisition by Roche) and CEO of Collectors (parent of PSA), making him a genuine power user of grading and marketplace products while serving as an active early-stage investor at Operator Partners.

Nat Turner's Interests

What they've been talking about across their social media accounts
  • Deep engagement with the business mechanics of the collectibles industry, particularly the infrastructure of grading and authentication. Frequently analyzes operational data from companies like PSA, such as citing specific submission numbers and counterfeit rates for high-profile assets like Michael Jordan rookie cards to illustrate market trends.
  • A focus on market data, asset valuation, and liquidity within alternative asset classes. Routinely tracks and broadcasts auction results for rare items, discussing price movements and population reports for vintage memorabilia like high-grade Mickey Mantle magazine covers.
  • Enthusiasm for 1990s sports nostalgia and the history of the trading card hobby. Often connects with the community by sharing personal experiences of opening vintage packs, referencing specific athletes like Vince Carter, or revisiting old industry publications to compare past market sentiments with the current landscape.
  • Attention to software quality and user experience in daily productivity tools. Highlights specific performance issues and bugs in popular email platforms, suggesting a founder-like focus on product reliability and a low tolerance for friction in workflow software.
  • Support for physical retail and community hubs within the hobby space. Actively promotes local card shops and gaming stores, such as praising a specific Pokemon-dedicated shop in New York City or a GameStop in a remote North Carolina town for their selection and atmosphere.

Avg Check Size

Operator Partners is a self-funded $40M-$70M venture fund run entirely on the partners' own money without outside investors, led by founders with billion-dollar exits including Flatiron Health (acquired by Roche) and the first investor in fintech unicorn Plaid. They deliberately avoid leading rounds or taking board seats, instead writing $250K-$1M checks alongside lead investors while offering on-demand operator support to founders who can go months without contact or request intensive help as needed.
