Company Launches

Hi everyone, We're @Gideon and Chidi, founders of Rulebase.

Problem

Voice-based frauds are growing exponentially, there was a 700% increase in voice phishing and deepfake voices in 2024, largely driven by the reasons below.

  • Scammers are using voice clones for phishing, account takeovers, and identity theft. Deploying 1,000 voice agents costs less than $55.
  • Fraudulent calls extend Average handling time (AHT), leaving service teams overstretched and reducing support for genuine customers.
  • Voice phishing costs up to $14 million per incident, straining resources and directly impacting the bottom line.

Solution
