Our case studies
Increase your sales without recruiting
Focus your team on closing
Your sales team is precious. If they're looking for leads, you're losing money. We prospect so that your team can do demos, negotiate and close deals.
Control your acquisition costs
Recruiting RDCs is expensive and risky. Training takes months. Staff turnover is high. Outsource your business development and turn fixed costs into predictable investments.
Validate new markets quickly
Growth demands rapid testing. We explore new markets and test your offerings so you can validate the product-market fit without risk.

They trust us
★★★★★
“Working with devlo was a real pleasure. Communication was very fluid and the team was always responsive. Their personalised approach enabled us to combine volume and quality, even though the target audience was difficult to reach. There were virtually no no-shows, and appointments were always qualified and effective. The lessons learned from the campaigns are also instructive and invaluable.”
★★★★★
“I recently completed an online course on B2B lead generation and making qualified appointments with potential customers, and it was a real game changer for me as a sales leader. The course provided me with practical techniques and strategies that I was able to immediately apply to my sales process. Since then, I've seen a significant increase in the number of qualified appointments I've been able to book.”
★★★★★
“I'm convinced that devlo is an ideal partner for start-ups looking to validate their product-market fit and get as many qualified appointments as possible with very little time and resources. The professionalism of its founder Charles has made the whole process, from lead generation to campaign structuring and appointment setting, a very enjoyable and efficient collaboration. To put our first campaign with devlo into perspective: 81% open rate, 54% response rate and 16% of organisations interested in an appointment with Saporo. That's remarkably effective, especially in a sector as complex as cybersecurity.”
★★★★★
“We really appreciated devlo's diligence, clear communication and dedication. Out of 285 prospects, we received 200 responses, which is over 70%. One of our challenges was to improve our prospecting methods. With devlo, we refined our targeting and our approach with lemlist. We also identified two types of Ideal Customer Profiles: private and public educational establishments. We contacted both and validated the ICP most receptive to our offer.”
★★★★★
“I was initially very attracted by the customer-centric approach, in particular the possibility of offering packages with clearly defined services and scope. This enabled me to clearly structure my campaign with a defined budget. We had dashboards showing the progress of the prospecting in real time. We then held a meeting to fully analyse the figures, understand what had gone well and what hadn't, and this enabled us to evaluate the campaign as a whole. I was very pleased.”
