Offchain Labs

Offchain Labs builds Arbitrum and Prysm, core Ethereum infrastructure that settles billions in DeFi value.

Offchain Labs

Offchain Labs maintains dual headquarters in Hong Kong and Princeton, operating as a protocol research and venture firm without a publicly disclosed family-office lineage. The firm was created by a core group of Ethereum researchers who authored Arbitrum’s optimistic rollup technology, which now settles billions in transaction volume as a Layer 2 on Ethereum. Offchain’s identity is anchored in its stewardship of two foundational Ethereum protocols: Arbitrum and Prysm. The firm’s intellectual engine, Offchain Labs, is the research entity behind Arbitrum’s continued technical development, while a separate enterprise-services division advises global companies on tokenized asset strategies and custom blockchain deployments. The firm’s deployment strategy flows through two venture vehicles that function as a capital-and-studio pipeline. Tandem operates as the primary equity investment arm, providing capital and strategic support to startups building on Arbitrum. Onchain Labs accelerates experimental applications within the Arbitrum ecosystem, aiming to convert proofs-of-concept into revenue-generating products. Offchain’s product suite reveals a full-stack infrastructure thesis: Arbitrum supplies the settlement layer for scalable decentralized applications, Prysm secures Ethereum’s consensus, and ZeroDev provides smart-account tooling to simplify user onboarding. Geographic focus reflects the dual-HQ structure, with development teams distributed across the US and Asia. The firm does not disclose total assets under management or aggregate deployment figures. Offchain Labs has not published team headcount or a formal list of principals. The firm’s technical leadership is traceable through Ethereum community research archives rather than a centralized corporate directory. Founders Ed Felten, Steven Goldfeder, and Harry Kalodner — all Princeton-affiliated computer scientists — are the known architects of Arbitrum. The venture arm Tandem and the ecosystem accelerator Onchain Labs suggest a lean operating structure, with capital deployment handled by a small partnership team rather than a multi-layered investment committee. In February 2024, the Arbitrum Orbit program expanded to allow developers to deploy Layer 3 chains using custom governance tokens, reinforcing Offchain’s posture as an infrastructure enabler rather than a passive capital allocator. Unlike traditional venture firms that source deal flow through a centralized partnership, Offchain Labs derives proprietary access from its position as the core developer of Arbitrum and a significant Ethereum consensus operator. This technical double-role — controlling both a leading Layer 2 network and the client software for Ethereum’s proof-of-stake consensus — gives the firm visibility into protocol-level activity that no external fund can replicate. Its investment arm Tandem operates as a captive venture studio, converting that infrastructure-scale intelligence into equity in teams building directly on Arbitrum’s stack.

Frequently asked questions

Who runs investment decisions at Offchain Labs?

Offchain Labs does not disclose a dedicated chief investment officer or investment committee. Venture allocation appears to be managed through the Tandem and Onchain Labs vehicles by the same Princeton-based founding team — Ed Felten, Steven Goldfeder, and Harry Kalodner — who designed Arbitrum. The firm has not published separate profiles for its investment staff.

Is Offchain Labs a family office or a venture firm?

Offchain Labs does not fit a single-family-office structure. It operates as a protocol research and development firm with a venture arm. There is no disclosed connection to a specific family wealth origin, and the firm does not manage capital on behalf of a single family. Its two venture vehicles, Tandem and Onchain Labs, function more like a corporate venture studio tied to the Arbitrum ecosystem.

Does Offchain Labs disclose its assets under management?

No. Offchain Labs does not publicly report aggregate AUM for its venture activities or treasury holdings. The firm’s economic model is tied to the Arbitrum token and the value of projects in its venture portfolio, neither of which is broken out in public disclosures.

What is the relationship between Offchain Labs and Arbitrum?

Offchain Labs is the original development firm that created Arbitrum and continues to serve as its primary technical steward. The firm built the Arbitrum optimistic rollup protocol, which settles transactions on Ethereum. It also operates Prysm, the consensus client that runs approximately 25% of Ethereum’s validator nodes, making Offchain Labs a significant infrastructure operator on both the Layer 1 and Layer 2.

How does Tandem select portfolio companies?

Tandem invests in teams building directly on Arbitrum’s rollup infrastructure, functioning as a captive venture studio. Offchain’s position as the Arbitrum core developer gives Tandem early visibility into projects before they scale. The firm has not published a formal investment mandate or sector-exclusion list, but its public messaging focuses on blockchain infrastructure, decentralized finance, and onchain enterprise applications.
