High-Level Overview
Proof Trading is an institutional equities broker-dealer and execution platform founded in 2019, headquartered in New York City. It operates as an execution-only broker-dealer, focusing on providing algorithmic trading solutions for institutional investors in U.S. equities. The firm’s mission centers on addressing inefficiencies and opacity in the traditional equities market by building a transparent, high-performance, cloud-native trading platform that reduces total cost of ownership (TCO) and enhances accountability. Proof Trading’s investment philosophy emphasizes scientific rigor, transparency, and unconflicted agency brokerage, aiming to optimize trading outcomes for long-term institutional clients. Its key sector is U.S. equities trading, with a broader impact on the startup and financial ecosystem by pioneering cloud-based, algorithm-driven trading infrastructure that challenges legacy market practices and promotes fairness and efficiency[1][2][3][4].
Origin Story
Proof Trading was founded in 2019 by Daniel Aisen and Allison Bishop, both bringing deep experience from the finance industry. The idea emerged from their recognition of contradictions in the U.S. equities market—where cutting-edge technology coexists with outdated manual processes and opaque pricing structures. Motivated to close this gap, they built Proof Trading from the ground up as a cloud-native platform, avoiding reliance on legacy systems or third-party solutions. Early traction included participation in Y Combinator’s Summer 2019 batch and securing partnerships such as with RBC Clearing & Custody in 2024 to scale trade processing capacity. This evolution reflects a deliberate focus on transparency, technological innovation, and client-centric execution[2][4][5].

Proof Trading rides the wave of digitization and cloud adoption in financial markets, addressing longstanding inefficiencies in equities trading. The timing is critical as institutional investors demand greater transparency, lower costs, and more sophisticated algorithmic execution amid increasing market complexity. Market forces such as regulatory scrutiny on broker-dealer conflicts and the rise of electronic trading platforms favor Proof’s model. By pioneering a cloud-native, open and accountable trading infrastructure, Proof influences the broader ecosystem by setting new standards for fairness and technological innovation in capital markets, potentially inspiring other fintech startups and institutional players to adopt similar principles[1][4].
Quick Take & Future Outlook
Looking ahead, Proof Trading is poised to expand its trading volumes and client base, leveraging partnerships like RBC Clearing & Custody to handle larger institutional trades. Trends shaping its journey include continued regulatory focus on transparency, advances in algorithmic trading, and growing institutional demand for cost-efficient, high-performance execution platforms. As Proof matures, its influence may extend beyond equities into other asset classes or geographies, and its commitment to open-sourcing technology could foster a broader community ecosystem. This trajectory aligns with its founding mission to transform the equities market into a more transparent, efficient, and client-aligned environment[1][4][5].
