A single database stops at its own coverage. A waterfall keeps looking until it finds a line that picks up.





"We were averaging 4 or 5 meaningful conversations a day before Sonik. Now we're at 12 per hour. The parallel dialer alone changed everything — but what really made the difference is showing up to every call with context. Our reps stopped sounding like they were reading from a script and started having real conversations. There is no turning back."


"As an agency, our entire business model depends on how efficiently we can prospect for clients. Sonik fundamentally changed that equation. We identify warm leads before we even pick up the phone, and every call is prepared by the AI. Our conversion rate doubled in the first month. This isn't just a tool — it's a competitive advantage we're not giving up."

"I was skeptical at first — we'd tried other dialers and they all felt like brute force tools. Sonik is different. The intent signals actually work. We're not just calling more people, we're calling the right people at the right time. My team hit quota three months in a row since we switched, and onboarding took less than a week."






Sonik uses waterfall enrichment. For each contact, we query several specialised data providers one after the other, starting with those strongest for the contact's country, and stop as soon as a mobile line is found. One provider alone covers a minority of contacts; the cascade is what brings coverage to 72%.
On average, Sonik finds a verified mobile number for 72% of the B2B contacts submitted by our customers. Coverage varies by country, seniority and industry: Europe is where our providers are strongest. We can run a free test on a sample of your contacts so you see your own find rate before committing.
Yes. Before a number reaches your reps we check that it is an active mobile line, that it matches the contact, and that it is not already in your CRM. Landlines and switchboards are filtered out. If a number turns out to be wrong during a call, Sonik flags it and looks for a replacement automatically.
Mobile numbers are part of Data & Signals and are billed per contact found, from €0.5 per mobile number. When we do not find a number, you pay nothing. Numbers are delivered into your CRM and your Sonik dialer, with no extra seat or platform fee.
Yes. Sonik only works with GDPR-compliant providers, limits the data to professional contact information, hosts it in the EU and lets every contact object at any time. Sonik acts as data processor for your campaigns and a DPA is available on request.
