Whistle

We provide a fully managed SDR team and done-for-you pipeline generation, running cold calling, cold email, and LinkedIn outreach for our clients. We also offer RevOps support for HubSpot, data on demand, conference lead generation, and vetted SDR hiring and placement. We work with B2B companies across SaaS and AI, cybersecurity, finance, marketing, EdTech, healthcare, HR and workforce, and real estate, spanning enterprise, growth-stage, and early-stage companies, with clients including Wix, Intel, Zendesk, and RingCentral. We are headquartered in London, United Kingdom, with teams operating across the United States, Israel, and Australia. We take new clients from onboarding to first outreach in 10 business days, place vetted SDR candidates within five days, and our clients typically see first meetings within 2 to 3 weeks of launch. Our case studies show over 100,000 dollars in pipeline generated and 7x to 10x return on investment.
