● The Problem

France switched to full opt-in for telemarketing on 11 August 2026, with fines up to 375,000 euros per call for companies. Sales teams keep consent evidence in CRM notes, form screenshots, and a spreadsheet nobody trusts. When a regulator asks for proof tied to one specific call, reconstructing it takes days.

● The Solution

A consent ledger that captures each opt-in with source, timestamp, exact wording shown, and IP, then exposes a pre-dial check that returns callable or not for a given number and jurisdiction. Every call attempt writes to an append-only audit record linked back to its consent event.

Go-to-Market Strategy

Lead with a free country-by-country cold calling rules page targeting searches like whether cold calling is legal in France. Charge $199/month by contact volume. Sell to voice AI dialer vendors as a white-label compliance layer, since their customers carry the liability.

Competitive Landscape

DNC.com and Contact Center Compliance cover US do-not-call lists and have not extended to EU opt-in regimes. OneTrust handles marketing consent for email and cookies rather than telephony, and prices for enterprise. Dialer vendors like Aircall and JustCall leave consent proof entirely to the customer.

Why Now?

The France ban took effect on 11 August 2026 and per-call fines make a single non-compliant campaign existential. AI voice agents are scaling outbound call volume at the exact moment the legal basis for those calls got stricter.
