## Questions

### What investment stages does Waterline Ventures target?

Waterline focuses on Seed through Series B investments in healthcare technology and services companies. The firm often leads or co-leads rounds and positions itself as a first institutional check for founders building at the intersection of software and healthcare delivery. It does not invest in preclinical therapeutics, medical devices, or diagnostic hardware.

### Which sectors does Waterline explicitly avoid?

Despite its Cambridge, Massachusetts location — a global hub for biotech and life sciences — Waterline Ventures does not invest in therapeutics, drug discovery platforms, medical devices, or diagnostics. The firm draws a hard boundary around software and tech-enabled services, avoiding capital-intensive, clinical-trial-dependent business models entirely.

### Does Waterline Ventures participate in fund commitments or only direct deals?

Waterline operates as a direct investor, writing equity checks into individual companies rather than committing capital to other venture funds. There is no public evidence the firm operates a fund-of-funds program or participates as a limited partner in external vehicles.

### How does Waterline Ventures source its deals?

Deal flow derives from the firm's embedded position in the digital health ecosystem — relationships with health system innovation groups, payer executives, and a network of portfolio founders who have exited or scaled. Greenglass's dual background in finance and healthcare operations provides a referral surface that spans both the venture and provider communities.

### What is Waterline Ventures' known portfolio concentration?

Per the firm's official communications, confirmed portfolio positions include Wellframe (acquired by Virgin Pulse), Firefly Health, and Qventus. The common thread across these positions is software applied to clinical workflow, care navigation, and hospital operations — a deliberate concentration rather than a broad health-tech sweep.
