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. devlo's Swiss roots are in the canton of Vaud, and devlo LLC also has a US address. Documented programmes cover Switzerland, Belgium, France and DACH.
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, then advances through test batches whose milestones and sample sizes are agreed before launch.
Founder

Charles Perret
Founder & CEO

Why outsource B2B prospecting to a specialist agency rather than an in-house team?
Outsourcing and an in-house team have different cost structures. Compare them on the same scope: recruitment, management, tools, data, available capacity, acceptance criteria and cost per qualified conversation.
devlo was founded in 2020 on a simple belief: a specialist outbound agency should instrument every pilot, document what it learns and adapt delivery to each market instead of promising a universal average.
Rather than building outbound infrastructure alone, clients scope tools, domains, responsibilities, acceptance criteria and launch conditions with devlo. Published case studies show the methods and outcomes that can be verified for each client.
In summary:
Key points
- Scoped cost: fees, tools, data, capacity and acceptance criteria are documented before launch so buyers can compare fully loaded cost on a common scope.
- Documented launch plan: infrastructure, tools, copywriting, lists and responsibilities are scoped before activation.
- Pilot milestones agreed before launch according to ICP, offer, channels and deliverability.
- Public client cases: each page describes the context, approach and results of an individual program.
