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.

By Charles Perret, Founder, devloWhy outsource B2B prospecting to a specialist agency rather than an in-house team?
Outsourcing B2B sales prospecting is a strategic decision based on a simple observation: recruiting, training and managing an in-house SDR team costs between CHF 80,000 and CHF 120,000 a year for a single profile, with no guarantee of results. According to Gartner 2024, 65% of in-house SDR teams do not achieve their pipeline targets within the first year.
devlo was founded in 2020 with the opposite belief: that a specialist outbound agency, with a proven infrastructure and a methodology tested on 1,000+ campaigns, can deliver measurable results from the 3rd week - at a fraction of the cost of an in-house team. Our clients in Switzerland, Belgium, France and DACH achieve an average 7% interest rate on the decision-makers they contact, which is 3 to 5 times the market average.
As a result, rather than building an outbound infrastructure from scratch - tools (Clay, LinkedIn Sales Navigator, Lemlist), dedicated domains, warm-up, copywriting - our clients start with a full operational team in less than a week. The result: 14 public case studies documenting hundreds of qualified appointments and millions of euros in pipeline generated.
In summary:
Key points
- Optimised cost: full outbound team for a fraction of the cost of an in-house SDR (CHF 2,500/month vs. CHF 80-120K/year).
- Operational in 1 week: infrastructure, tools, copywriting and prospect lists - all included.
- Results from D+15: first qualified appointments between the 2nd and 3rd week, not in 6 months.
- 14 public customer cases: Horus (80 RDV, €200K), Monizze (120 RDV), Cortexia (71 RDV) - verifiable metrics.
