## Questions

### Who makes investment decisions at VIMAC Ventures?

John Simon, the firm's co-founder and Managing Director, has made all final investment committee decisions since 1997. There is no public evidence of a distributed partnership vote structure — Simon operates as the sole decision-maker, which is unusual for a venture firm approaching three decades of operations.

### What stage does VIMAC Ventures typically target?

VIMAC targets seed and Series A rounds, with initial checks ranging from $500,000 to $3 million. The firm reserves follow-on capital for companies that hit technical and commercial milestones. It does not participate in growth-stage rounds or later-stage pre-IPO financing.

### Which sectors does VIMAC explicitly avoid?

VIMAC does not invest in consumer internet, media, entertainment, or luxury sectors. The firm has exclusively backed enterprise technology — infrastructure software, AI/ML, digital health, fintech, and industrial technology — since founding. No public record exists of a VIMAC investment in a B2C company.

### How does VIMAC differ from larger Boston venture firms?

VIMAC has not scaled beyond its lean partnership structure — unlike General Catalyst or Bessemer, which have diversified into growth equity, public markets, and international offices. Simon's firm remains a single-office, early-stage-only vehicle that has deployed capital across four technology cycles without broadening its mandate.

### What is VIMAC's most notable exit?

Nuance Communications, a speech recognition and enterprise AI company, sold to Microsoft for $19.7 billion in March 2022. VIMAC was an early backer. The firm also held a position in Endeca Technologies, an enterprise search company acquired by Oracle in 2011.

### Does VIMAC participate in fund commitments or only direct deals?

VIMAC only makes direct seed and Series A investments. There is no public record of the firm committing capital as a limited partner to other venture funds, nor does it operate a fund-of-funds program or participate in club deals with external managers.

### Is VIMAC raising a new fund?

No public fundraise has been announced since 2023. VIMAC historically raises funds on a 3- to 4-year cycle, with previous vehicles in the $50 million to $100 million range, but the firm does not disclose AUM publicly.
