ECentury Capital Partners

Susan Heffern, the firm's founder and managing partner, chairs the investment committee and makes all final allocation decisions. She built ECentury after a career at Riggs Bank, where she advised institutional and family-office clients in the Washington, D.C. region. The firm does not publicly list additional investment committee members, suggesting a centralized decision structure (per public record).

ECentury leans on a geographic advantage: a three-decade network in the Mid-Atlantic's intelligence-community, defense-contractor, and enterprise-technology clusters. The firm's presence in Vienna, Virginia puts it near the NSA, defense agencies, and the dense formation of cybersecurity startups that spin out of government service. Heffern's board seats at portfolio companies and relationships with co-investing family offices create a referral loop that coastal firms rarely replicate at early stages.

Both. ECentury started as a fund-of-funds — writing commitments to early-stage venture managers — and used that vantage to identify GPs worth co-investing alongside. Over time, the firm layered on direct seed and Series A checks, opportunistic secondary purchases, and special-purpose vehicles. The fund-of-funds portfolio still functions as a research pipeline: ECentury sees which managers are winning deals in enterprise and cyber, then writes direct checks into those managers' portfolio companies.

The firm concentrates on enterprise software, cybersecurity, artificial intelligence and machine learning, digital health, and industrial technology. Its early exits — Sourcefire and NetWitness — set a cybersecurity thesis that still defines the portfolio. ECentury does not publicly disclose real estate, consumer internet, biotechnology, or hardware as active areas of investment.

ECentury writes primary fund commitments to early-stage venture managers, directly co-invests at seed and Series A alongside those managers, and opportunistically acquires secondary positions in venture portfolios. The firm also makes a limited number of direct investments from seed through growth equity. The common thread across all four lanes is enterprise-technology exposure concentrated in the East Coast market.

While ECentury's LP base includes Mid-Atlantic family offices — making it a multi-family office in structure — the firm operates more like a venture capital fund. It raises blind-pool vehicles with outside institutional capital, not just family money, and it competes for allocations as a GP rather than serving as a concierge investment office for families. Susan Heffern maintains personal advisory relationships with co-investing families, but the firm's primary business is fund management.

No. ECentury does not publicly disclose assets under management, fund-level returns, or deployment totals. The firm's last publicly known fundraising target was $125 million for ECentury VI in 2022, but final close figures were not reported. The firm maintains the privacy posture typical of family-office-adjacent vehicles in the Mid-Atlantic market.
