The market for B2B prospecting agencies has grown considerably since 2020: there are now dozens of players in France, Switzerland, Belgium and the DACH. When it comes to choosing the right partner, there are five key criteria: expertise in outbound channels, language coverage, speed of initial results, transparent reporting and verifiable customer proof.
devlo stands out on these five criteria: a Swiss agency specialising exclusively in B2B outbound since 2020, our team has mastered cold email, LinkedIn outreach and cold calling in FR, DE, EN and native NL. According to a Gartner 2024 study, specialist outbound agencies generate 2.8 times more appointments than full-service agencies that treat prospecting as a secondary service. In fact, our average interest rate of 7% over 1,000+ campaigns confirms this.
So before selecting an agency, ask yourself these questions: Do you have public case studies with precise metrics? How long before the first meetings? Do you prospect natively in my target languages? At devlo, the answers are : 14 public cases, first appointments as early as D+15, and native FR/DE/EN/NL teams.
In summary:
Key points
- Outbound specialist only: not a full-service agency that does everything - exclusive focus on cold email, LinkedIn and calling.
- 14 public case studies with precise metrics: appointments, pipeline, sales - all verifiable before signing.
- First results in 3 weeks: 2-week test phase, then full-scale roll-out with measurable results.
- Native FR/DE/EN/NL: coverage of Switzerland, Belgium, France, DACH and BeNeLux without intermediary partners.
