[ 01.d / SEE IT WORKING ]

This is the outcome, not a promise of one

A worked example of exactly what this build does once it is live in your business.

Live example Real customers in, fakes out
  • 00:00Signup attempt from a number we have never seen.
  • 00:01Number checked: prepaid mobile, carrier known, not a virtual range.
  • 00:03Code sent. Rate limits applied by number, account and address.
  • 00:19Verified. Account created.
  • 00:22Second attempt, same number, third account today. Blocked.
[ WHAT YOU GET ]

Outcomes

  • Fewer no-shows because the reminder always goes out
  • Leads answered in seconds instead of hours
  • A written record of every customer conversation
[ HOW IT WORKS ]

Identity assurance

A code, push or cryptographic challenge is issued to a channel the customer controls, then checked with strict rate limits and short expiry.

  1. Pick the primary channel by delivery rate in your actual customer base
  2. Set the fallback order and the retry backoff
  3. Rate limit by number, by account and by IP
  4. Log every attempt for the audit trail without logging the code itself
[ 01.g / WHAT YOU ARE BUYING ]

Four things that are true of every build

The terms are the same whether you spend two thousand dollars with us or twenty.

[ 01 ]

A fixed price

Quoted before we start, naming what it does and what it will not do. It does not move unless you change the scope in writing.

[ 02 ]

Proof before launch

You sign off on real output from your own cases, not a demo video. If it does not convince you, it does not go live.

[ 03 ]

Everything in your name

Accounts, numbers, data, repository. Nothing switches off if you stop working with us, and there is no migration to negotiate.

[ 04 ]

30 days of fixes free

Anything that does not behave the way we said it would gets fixed at our cost for the first 30 days, whether or not you take the managed plan.
