About us

Finding customers is the hardest problem in business. And we’ve solved it. Thousands of times.

We are a global SDR Agency that works with startups and scale-ups throughout the US, UK, Europe, India, Israel and Australia to drive increased and predictable sales through SDR, sales and marketing services. Our aim is to give fast-growing companies a better chance of success in scaling global growth.

Whistle is headed by brothers David and Yonah Zeff and was founded in 2020, following 3 tech exits spanning a decade in SaaS sales. A tight-knit team that started with just 5, has quickly grown into a lean, mean sales machine consisting of more than 80 people, servicing dozens of companies around the world.

Our Culture

Creating a company culture in a 100% remote company is kinda like trying to keep the spark alive in a long distance relationship: it takes A LOT of communication and even more creativity.

We make a point of vocalizing every single win (and loss) so that the whole team is always in touch with what is happening within Whistle. We celebrate together when things go right and, when they don’t, we work together to find a solution.

We believe that innovation shouldn’t only come from “the top”, but rather it should be something that stems from the experience gained on the front-line of sales development. The only way that we can become, and remain, the #1 leader in our category is by relying on innovation, ideas and advice from all 80+ Whistlers. We don’t only encourage innovation and self-starter attitudes, we reward it.
