Vendisys

We provide a fully managed outbound infrastructure that a client's internal SDR or founder-led sales team uses to generate demos. We set up and integrate the tech stack, including Clay, Apollo, email platforms, LinkedIn automation, and calendar tools, define ideal customer profiles and enrich contact data, execute multi-channel outreach across email, LinkedIn, and calendar invites, personalize messaging with AI, and deliver reporting and ongoing optimization. We serve B2B tech companies and enterprise clients, from Fortune 500 companies to fast-growing SaaS businesses, who want outbound efficiency without hiring or outsourcing a full SDR team. We are based in San Francisco, California, in the United States. We have 23 years of pipeline-building expertise, have served over 2,200 B2B tech clients, and have generated more than 100,000 demos and influenced over $1 billion in pipeline. We are rated a G2 High Performer at 4.9 out of 5, and our approach is built to give clients the machine while they keep control, rather than replacing their team with an outsourced call center.
