## Questions

### What does the name 'Step Function VC' signify about the firm's investment strategy?

The name references the mathematical step function — a signal that jumps discontinuously from one value to another. The firm applies this concept to startup investing by targeting companies at the precise moment when a technical breakthrough, market shift, or regulatory change enables a non-linear acceleration in growth. This threshold-based approach means the partnership evaluates not just whether a company is promising, but whether it has crossed the specific catalysts required for exponential rather than incremental progress.

### What investment stages does Step Function VC typically target?

The firm focuses on seed through Series A investments, where the gap between current valuation and step-change potential is widest. Initial checks are sized for early-stage technical companies, with significant reserves held for follow-on investments in its highest-conviction positions. This concentrated approach distinguishes it from seed funds that write dozens of small checks with minimal follow-on engagement.

### Which sectors does Step Function VC concentrate on?

The firm gravitates toward enterprise software, AI/ML, and industrial technology — sectors where technical defensibility and engineering depth create durable competitive advantages. The partnership avoids sectors where network effects or brand economics dominate, preferring IP-dense businesses where a first-principles technical evaluation can produce genuine investment conviction independent of market consensus.

### Where does Step Function VC primarily source its deal flow?

Geographic sourcing concentrates on the Northeast corridor, particularly the Boston-Cambridge innovation ecosystem, where proximity to MIT, Harvard, and the region's deep-tech incubators provides a structural advantage. The firm cultivates relationships with university spinout programs, technical syndicates, and aligned seed funds that refer companies fitting its threshold-based thesis. The partnership supplements local sourcing with opportunistic investments in exceptional technical teams regardless of geography.
