OpAmp Capital

OpAmp concentrates on pre-seed and seed-stage companies. The firm will consider pre-revenue startups when the technology and market opportunity are compelling, but it generally looks for some form of market validation, such as early customer traction. Its typical check size falls between $250,000 and $500,000, and it prefers to co-invest alongside other established venture firms.

The firm self-identifies as a frontier-technology investor, with stated focuses on space, applied AI, drones, automation, and defense technology. Partner bios and investment activity reveal additional depth in geospatial intelligence, satellite communications, and enterprise hardware. OpAmp’s mandate is broad enough to consider market-disrupting deals outside these verticals, but its partnership’s collective expertise centers on deep-tech domains with significant engineering or government-procurement complexity.

OpAmp sources globally through a partner network that spans Los Angeles, Taipei, and Washington, D.C. The partnership’s backgrounds — spanning satellite operations, venture capital in Silicon Valley (Renovation Global Fund), and advisory roles at Seraphim Space Fund — surface deal flow from both US defense-technology ecosystems and Asian markets. The firm also benefits from connections into the Space Force enterprise community through a partner’s leadership role at the NSTXL Space Force Enterprise Consortium.

The firm does not publicly delineate a formal investment committee structure, but its investing activity centers on a small partnership group. Josephine, a former Head of Research at Seraphim Capital, leads space and geospatial-intelligence deals. Craig, the co-founder, brings satellite-operator and large-scale capital-raising experience from the ProtoStar program. The broader partnership contributes venture investing and corporate finance experience from Renovation Global Fund, Standard Foods, and ViewSonic.

OpAmp’s website and available materials describe only direct, early-stage equity investments. There is no mention of fund-of-funds commitments, LP positions in other venture funds, or secondary-market activity. The firm’s value proposition centers on writing initial checks and supporting portfolio companies with operational mentorship and follow-on capital introductions.

The firm’s co-founder Craig raised over $500 million in venture and debt financing for ProtoStar Ltd. and oversaw the construction and launch of geostationary satellites. This hands-on experience in spacecraft procurement, manufacturing, and regulatory navigation gives OpAmp a technical diligence capability that is rare for a fund writing sub-$500,000 checks. Partner Josephine’s work covering commercial spy satellites and drones for national-security applications adds a layer of intelligence-community insight into product requirements and procurement timelines for defense-adjacent startups.

OpAmp is headquartered in Vienna, Virginia, but the firm explicitly states it operates without territorial boundaries. Partner representation in Los Angeles, Taipei, and Washington, D.C., supports a pipeline that reaches across North America and Asia. The firm’s leadership has historical operating and investing experience in both the US and Asian markets, including Taiwan and Hong Kong, and it describes its mandate as globally opportunistic.
