• Built financial crime prevention systems protecting billions in transaction value
• Created platform enabling other fintech innovation through payment infrastructure as a service

Stripe exemplifies how infrastructure start-ups, while less visible than consumer-facing companies, can create enormous value by solving fundamental problems that unlock innovation throughout entire industries. The company’s success enabled e-commerce expansion and democratized online business creation.

Chime: Reimagining Banking for Underserved Americans

Chime has become one of America’s largest neobanks by serving populations underserved by traditional banking—particularly those living paycheck-to-paycheck, overdrafting frequently, and unable to maintain minimum balance requirements. The company offers fee-free banking, early wage access, automatic savings tools, and overdraft protection without penalty fees.

Traditional banks profit substantially from overdraft fees, check cashing fees, and account minimums that disproportionately burden lower-income customers. Chime’s business model instead relies on interchange fees from debit card usage, eliminating incentives to extract fees from vulnerable customers. This approach resonated powerfully—Chime has grown to over 14 million accounts and achieved valuations exceeding $25 billion.

The company’s features like “SpotMe” allowing small overdrafts without fees and automatic savings programs that round up purchases have helped millions build financial resilience. While critics note Chime isn’t technically a bank (it partners with chartered banks) and its revenue model still depends on encouraging spending, it has demonstrably provided value to populations excluded or exploited by traditional banking.

Plaid: Connecting Financial Accounts

Plaid built connective tissue enabling thousands of fintech applications to access users’ bank accounts with permission. Before Plaid, apps wanting to verify account balances, initiate transfers, or analyze transaction history required users to share bank login credentials—a security nightmare. Plaid created secure APIs connecting apps to financial institutions, enabling the fintech explosion of the 2010s.

The company’s technology powers countless consumer finance apps including Venmo, Coinbase, Robinhood, and thousands of others that need to connect to bank accounts. This infrastructure role made Plaid critical to fintech ecosystem development while creating a valuable business—Visa attempted to acquire Plaid for $5.3 billion before antitrust concerns scuttled the deal.

CRISPR Therapeutics: Gene Editing Becomes Medicine

CRISPR Therapeutics, co-founded by Nobel laureate Emmanuelle Charpentier, is translating CRISPR gene editing from research tool to therapeutic reality. The company’s lead program, developed with Vertex Pharmaceuticals, treats sickle cell disease and beta thalassemia through ex vivo gene editing—extracting patients’ stem cells, correcting the genetic mutation causing disease, and reinfusing the edited cells.

Clinical trial results have been remarkable—patients with debilitating genetic blood disorders experiencing complete remission after single treatments. In late 2023, regulators approved the first CRISPR-based therapy, representing a watershed moment for gene editing medicine. While current approaches require complex procedures costing millions per patient, they demonstrate proof-of-concept for using gene editing to cure genetic diseases.

CRISPR Therapeutics is advancing next-generation approaches including in vivo gene editing (editing genes directly in the body) and more efficient delivery methods that could dramatically expand accessibility. The company’s progress transforms what once seemed like science fiction into clinical reality.

Recursion Pharmaceuticals: AI-Powered Drug Discovery

Recursion Pharmaceuticals is pioneering AI-driven drug discovery using massive datasets of cellular images. The company treats cells with thousands of compounds, images the results using high-throughput microscopy, then applies machine learning to identify cellular changes associated with disease reversal or modulation.

This approach generates extraordinary data volumes—Recursion has created one of the world’s largest biological datasets with tens of billions of cellular images. Machine learning algorithms identify patterns invisible to human observers, suggesting drug candidates and disease mechanisms that traditional research might never discover. The company can screen thousands of compounds across hundreds of disease models monthly—scale impossible with traditional laboratory approaches.

Recursion’s platform has identified clinical candidates for rare diseases, cancer, inflammation, and other conditions.
