Our story
B2B outbound specialists since 2020
devlo was founded in Lausanne in 2020 with a simple conviction: outsourced B2B prospecting should produce measurable results, not vague promises. Since then, we've deployed over 1,000 campaigns for clients in Switzerland, Belgium, France, DACH and North America.
Our team has mastered the three outbound channels that convert best in B2B: cold email, LinkedIn outreach and cold calling. We're not a full-service agency - we're outbound specialists, and only outbound specialists.
Our method combines Swiss rigour with in-depth knowledge of local markets. Each campaign starts with an ICP workshop, followed by a two-week test phase and then a full-scale roll-out. The results are measurable from the third week onwards.
