Pricing Structure & Competitor Comparison

A: Synthflow AI uses a tiered pricing model starting at $29/month for the Starter plan (50 minutes, 5 concurrent calls), scaling to $450/month for Pro (2,000 minutes, 25 concurrent calls), $900/month for Growth (4,000 minutes, 50 concurrent calls), and $1,400/month for Agency (6,000 minutes, 80 concurrent calls, white-label features).
