How it works

A crew that works every case

Six steps from finding a business to a pitch you're proud to send.

  1. 01

    Scout

    Finds businesses by industry and city on Google Maps, and opens a case for each one.

  2. 02

    Inspector

    Audits each website: speed, search, getting calls, security, email, tracking and more.

  3. 03

    Tracer

    Finds the contact details the business publishes, and checks the email can receive mail.

  4. 04

    StrategistComing soon

    Picks the angle: which finding to lead with and which service to offer.

  5. 05

    WriterComing soon

    Drafts a short, specific email that quotes only the audit's evidence.

  6. 06

    Sign-off desk

    You read the draft beside its evidence, edit if you like, and approve.

The audit

Nine areas, measured, not guessed

Each finding becomes a numbered exhibit with its source and the time it was measured.

  • SpeedGoogle's mobile and desktop scores, real-user load times
  • Search (SEO)Titles, descriptions, headings, schema, sitemap
  • Getting callsTap-to-call phone, contact forms
  • SecurityHTTPS, certificate expiry, security headers
  • Email healthSPF and DMARC: will their emails reach inboxes?
  • TrackingAnalytics, ad tags, cookie consent
  • AccessibilityGoogle's accessibility score, image descriptions
  • AI assistantsCan AI search tools read and recommend the site?
  • TechnologyPlatform, page builder, email provider

What the draft says

“Your number can’t be tapped on a phone…”

EXH-B · Getting calls

0 tap-to-call links; phone shown as plain text

You stay in control

Evidence first. Your sign-off always.

  • Nothing goes out without you

    Every draft waits at the sign-off desk with its evidence beside it. Approve with one key, or edit first.

  • Claims can't be invented

    A draft that cites no evidence can't be approved. Findings come from measurements, not from writing.

  • Your clients stay off-limits

    Mark a business as a client and it can never be pitched: no drafts, no new cases.

  • Plain English first

    Every finding says what it costs the business, with the technical detail one click away.

Security

Built to hold sensitive work

  • Two-factor sign-in

    Password plus an authenticator app, enforced by the database as well as the app.

  • Sealed workspaces

    Each agency's cases, contacts and drafts are separated in the database itself.

  • Evidence can't be edited

    Audit findings are written only by the audit, with their source and time.

  • Encrypted secrets

    API keys and inbox access are stored encrypted and never shown again.

Outreach rules follow each prospect’s country:

  • Canada
  • United States
  • United Kingdom
  • European Union
  • Pakistan

Every pitch, backed by evidence.
