Frequently asked questions

Who makes investment decisions at Greenhills Ventures?

Michael Puscar, the firm's founder and Managing Partner, drives all investment decisions. Puscar brings an operator's lens as a former data-science entrepreneur who built and sold text-analytics firm Giva. He is heavily involved in technical diligence, often auditing architecture personally before committing. The firm has not publicized an investment committee or additional deal professionals.

How does Greenhills source its deals?

Sourcing flows from Puscar's deep network in applied-AI engineering communities, particularly in New York and Estonia, where he has personal ties dating to his prior startup exits. The firm does not run an outbound associate program or rely on advisor networks. Portfolio firm Pactum's expansion to Walmart-scale deployments in 2023 also creates a reference case that draws inbound founder interest.

Is Greenhills a fund or does it invest off the managing partner's personal balance sheet?

Greenhills operates as a personal investment vehicle funded by Michael Puscar's exit capital and reinvested gains. It has not disclosed any external limited partners or fund structures. This permanent-capital posture means the firm can hold positions indefinitely, without the pressure to distribute that a ten-year fund vehicle would face.

What check size and stage does Greenhills typically target?

The firm targets pre-seed and seed rounds, writing checks large enough to be a material lead or co-lead. While precise check sizes are not publicly disclosed, the portfolio concentration suggests positions designed for board influence rather than passive exposure. Investments include Pactum, an AI procurement startup, and BLOX, an energy forecaster.

Does Greenhills invest outside the United States?

Yes. While headquartered in New York, the firm invests selectively in Northern Europe, particularly Estonia, where Puscar has deep relationships and where Pactum is based. The geographic footprint is narrow — North America and the Baltic technology corridor — rather than a global mandate.

What sectors does Greenhills avoid?

The firm stays away from consumer internet, hardware-intensive deep tech, and capital-heavy sectors like industrials or real assets, consistent with its early-stage enterprise-software focus. It also has not made any publicly disclosed investments in pure biotech or pharmaceutical infrastructure.

Is Greenhills Ventures affiliated with any broader family office or parent entity?

No parent entity, multi-family platform, or philanthropic arm is publicly disclosed. Greenhills Ventures is a standalone vehicle for Michael Puscar's personal investing activity. The firm does not belong to any known co-investor clubs or family-office peer networks.
