KEC Ventures
KEC Ventures was established in 2011 as the single-family office for Jeffrey Citron. Citron built the underlying wealth through Datek Online and Vonage. The office also supports Suzanne Citron’s work with the Charles Lafitte Foundation. The firm invests in pre-seed, seed and Series A rounds. Asset classes include enterprise software, fintech, digital health, proptech and insurtech. It operates exclusively in North America and favors direct equity positions in startups. Confirmed holdings and co-investors are not publicly detailed beyond the general strategy. Team size and additional offices remain undisclosed. The firm lists residential assets in Middletown, New Jersey and Riviera Beach, Florida, plus a Gulfstream G-IV. No operational events from the last 24 months appear in available records. KEC’s structure keeps investment decisions inside the family office rather than through external fund vehicles. This setup allows direct, long-duration ownership without limited-partner reporting cycles.
