Testimonials
"They rebuilt our entire lead pipeline in 3 weeks. We went from 40 leads a month to over 200, and every single one came with a full profile. Our close rate doubled."

Philipp Angermann
Founder of Founderstack
"We were spending 8k a month on Meta with nothing to show for it. Within 60 days we hit a 6.2x ROAS. Best investment we made all year."

Eleanor Parnell
Co-Founder of Visualise Brands
"Before CERTO our sales team was cold calling from a spreadsheet. Now they get enriched profiles with mobile numbers and company data. Revenue went up 35% in the first quarter."

Sebastian Membrez
CEO of OnnoPlus
"We went from zero pipeline to 15 qualified calls a week in under a month. The enrichment layer alone changed how we sell."

Roman Hipp
Founder and CCO of BetterContact
"Our CRM was a mess. They built the entire HubSpot pipeline, set up scoring and sequences, and within 6 weeks our team knew exactly who to call and when."

Daniel Wild
Lead Investor and Co-CEO of Vortecx
"We tested 3 agencies before. None of them enriched a single lead. CERTO gave us full profiles from day one. That was the difference."

Gregor Zange
Founder of EnrichBox
