Modular Capital is a United States-based venture fund built around a single thesis: that the future of blockchain belongs to modular architectures. The firm bets on projects that separate the core functions of a blockchain – execution, settlement, consensus, and data availability – rather than bundling them into a single monolithic chain. This focus places Modular Capital squarely in the infrastructure layer of crypto, backing the picks-and-shovels of the so-called "modular blockchain" movement.
The fund was founded around 2022, when the modular thesis was gaining serious traction among protocol researchers and developers. According to Crunchbase, Modular Capital operates as an early-stage venture investor, concentrating on protocol-layer projects rather than consumer applications or centralized exchanges. Its relatively compact portfolio – approximately ten disclosed investments – reflects a high-conviction, concentrated approach rather than spray-and-pray deployment.
Notable Investments
Modular Capital's portfolio centers on infrastructure projects tied to the modular blockchain stack. The firm is publicly associated with investments in:
- Celestia (TIA) – the leading modular data availability network, widely considered the flagship project of the modular movement. Celestia allows blockchains to publish and order transaction data without executing it, reducing costs and enabling rollup sovereignty.
- Eclipse – a Solana Virtual Machine rollup settling on Ethereum, using Celestia for data availability. Eclipse combines high throughput execution with Ethereum's security, a prime example of the modular stack in practice.
- Avail – a modular data availability and consensus layer spun out from Polygon. Avail competes directly with Celestia for rollup and appchain data availability.
Public information about the full ten-project portfolio is limited. The firm has not disclosed all holdings or deal sizes publicly.
Team
James Ho is the primary public face of Modular Capital, serving as a managing partner. Ho has a background spanning traditional finance and crypto-native investing, and is a frequent commentator on modular blockchain architecture in research threads and industry panels. Public information about additional partners or analysts at the firm is limited.
Recent Activity
Through 2024 and into 2025, Modular Capital remained active as rollup infrastructure matured. The broader modular ecosystem saw significant growth: Celestia's mainnet launched in late 2023 and TIA became one of the higher-profile token launches of that cycle. Eclipse went live on mainnet in late 2024. Both events represented meaningful milestones for Modular Capital's core thesis investments.
The fund's retail ROI figure of 0.08 reflects the early-stage, infrastructure-heavy nature of its portfolio – these are long-horizon bets where tokens are typically locked for extended periods and value accrual depends on developer adoption rather than short-term price action.
Total AUM has not been publicly disclosed. With one confirmed lead investment and roughly ten total positions, Modular Capital appears to operate as a smaller, thesis-driven fund rather than a multi-hundred-million dollar generalist vehicle.
Outlook
Modular Capital's thesis has proven directionally correct: rollups, data availability layers, and modular execution environments are now central to Ethereum's scaling roadmap and beyond. The key open question is whether modular infrastructure projects can capture sufficient value at the token layer to justify their current valuations. If the modular stack becomes commodity infrastructure – widely used but poorly monetized – early investors may find returns compressed. If data availability fees and protocol revenue scale with adoption, the fund's concentrated bets stand to perform well over a multi-year horizon.
