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.

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.

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.

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.

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.
