In this role, he gained early exposure to financial analysis, corporate strategy, and the workings of global capital markets. The experience provided him with a strong foundation in understanding complex financial systems and how institutions assess risk, value assets, and execute strategic decisions. These early lessons would later shape his approach to entrepreneurship and building financial technology solutions.

In 2013, Stern co-founded his first company, Shout Inc., a consumer-focused startup. Over two years, he led product development, business operations, and customer engagement. Reflecting in a September 2025 podcast, Stern noted that the experience taught him the value of iteration, rapid decision-making, and responding to market feedback.

Transition to Technology and Engineering

In 2016, Stern shifted to the tech sector as a forward-deployed engineer at Palantir Technologies, implementing data-driven software solutions for clients. He joined Mark43 in 2017 as a software engineer, contributing to public safety technology systems that enhance efficiency and outcomes for law enforcement.

From 2018 to 2020, Stern worked as a research scientist at Protocol Labs, focusing on decentralized systems and blockchain protocols. During this period, he contributed to research and development for the Filecoin network, exploring distributed storage, consensus mechanisms, and secure digital asset exchange. These roles allowed Stern to combine technical expertise with problem-solving skills, preparing him for the challenges of leading a blockchain-focused startup.

Founding and Growing Privy

In September 2021, Stern teamed up with Asta Li to co-found Privy, stepping in as CEO. The company started out with a simple but powerful idea: linking everyday user information, like email addresses and names, to crypto addresses on the blockchain. In doing so, Privy aimed to create a bridge between traditional identity systems and the world of blockchain applications.

The company began prioritizing things like user authentication, secure key management, and making it easier for people to get started with blockchain apps. This change highlighted Stern’s dedication to building products that not only meet developers’ needs but also stay in step with the evolving market.

Funding, Acquisition, and Industry Impact

Privy’s growth attracted notable institutional support. In November 2023, the company raised an $18 million Series A round led by Paradigm, following earlier backing from Sequoia Capital. This funding enabled the company to scale its products, strengthen security features, and expand its team.

On June 11, 2025, Stern announced that Privy had been acquired by Stripe, a move aimed at improving access to regulated crypto infrastructure for businesses such as neobanks and DeFi platforms. Despite the acquisition, Privy continues to operate independently within Stripe, maintaining its focus on user-friendly and secure blockchain solutions. Throughout his career, Stern has combined expertise in finance, engineering, and research to make a meaningful impact on the crypto and fintech ecosystem.
