From the first meeting with YL Ventures’ team we realized we’re dealing with true professionals, but we couldn’t imagine how great their support and involvement would be in such a short period of time. Right from the start Yoav & Ofer acted as part of the founding team, providing invaluable support in all aspects of our business - from giving us strategic advice through connecting us with their broad business network and helping with marketing efforts. We couldn’t ask for better partners!"

YL Ventures has been an invaluable ally to Seculert at every step of the company's evolution. Yoav shares our vision of Seculert providing the world’s most advanced cloud-based malware detection service. His financial support is obvious: the first dollar invested in the company, more capital each subsequent round and spearheading our securing additional financing at the optimal point thereafter. Beyond that, he provides the type of sage advice, insights and hands-on involvement critical to growing the company to be strategically well-positioned as a leader in this exciting and dynamic market."
Yoav's personal commitment to us was strong from investment to exit. He rolled up his sleeves and worked hard for AcceloWeb. He was responsive and efficient – getting back to us quickly, prioritizing our needs at the top."
