Decima Ventures

Decima Ventures is a technology investment group founded in 2001 by Rony Zarom, a serial entrepreneur who sold Exalink for $550 million to Comverse — ticker CNSI on NASDAQ — just 14 months after establishing the company. Headquartered in Jamesburg, New Jersey with offices in New York City and Tel Aviv, the firm invests selectively in early-stage tech companies in cybersecurity, video, messaging, and social technology across Israel and the United States. Zarom's demonstrated ability to build and sell a company at high velocity gives Decima a founder-authentic perspective on the product and go-to-market decisions its portfolio companies face. The firm writes checks from $50,000 to $4 million at seed and Series A stages, taking a concentrated approach with 11 total investments and 2 exits. Portfolio companies include Axxana in data protection, Cybonet in cybersecurity, PineApp in email security, Watchitoo in interactive video, Newrow in online education, and Chatway in secure group chat. The firm's security and communications concentration reflects both the founders' backgrounds and Israel's global strength in these categories. Decima's four-member team takes a selective, deep-commitment approach — the firm invests in fewer companies to ensure that each portfolio company receives genuine attention and support. Zarom and the team engage directly in strategy and execution decisions, applying the operational experience of a successful serial founder to help portfolio companies navigate the path from early product to scalable business.
