The choice between two B2B prospecting agencies is not just about price -- it comes down to geographical coverage, channel expertise and speed of initial results. devlo and Undersales both operate in the French-speaking market, but their scope diverges significantly as soon as you look at the Swiss, German-speaking and DACH markets.
devlo has been based in Switzerland since 2020 and has deployed more than 500 campaigns in Switzerland, Belgium, France and DACH. Our team writes and prospects natively in FR, DE, EN and NL -- a decisive advantage for companies targeting multiple markets simultaneously. According to HubSpot 2024, native-language messages generate 2.1 times more responses than translated messages.
Therefore, if your target market includes German-speaking Switzerland, DACH or the Netherlands, devlo offers integrated coverage that Undersales does not provide. Our clients get their first appointments from the 3rd week, with a real-time tracking dashboard and a dedicated weekly call.
