Trusted by teams running outbound today
Cut your calling costs by 60%.
Keep your workflow simple.
No APIs, no complex integrations. Just upload your list and let our agents handle the rest.
Zero Integration Required
Forget complex APIs. Simply upload your .xlsx or .csv lead list. We handle the dialing and return an enriched file with recordings, transcripts, and lead scores.
Priced Around the Outcome
At $0.03/minute with no subscription, qualifying a thousand-lead list costs less than a single day of manual dialing, and you only pay for calls that connect.
Smart Lead Filtration
Don't waste your sales team's time on dead leads. Our AI agents qualify prospects, detect voicemails, and filter your list so you focus only on warm opportunities.
Proof, not adjectives
Hear what the agent actually said.
A quote on its own is the weakest proof on any page. Each slide pairs one campaign’s numbers with the call it produced, agent side included, so you can hear it instead of taking our word for it.
“We had a list nobody had touched in eighteen months. Kolz worked through it in three days and gave us back a shortlist our closers actually called.”
Operations lead, agency running outbound for four clients
Agent“You asked about a quote back in March. Is that still something you are looking at this quarter?”
Lead“Actually yes, we pushed it but the budget is approved now.”
Sample data, swapped for real campaigns and recordings as they clear for publishing.
