Method

A 14-day cycle, and the system learns before the next one opens.

A cell is one trade in one city. It gets picked on data, audited in full, worked on whatever channel each business actually has, and closed with a measured cost per meeting. That number decides which cell opens next.

The five moments of a cycle

  1. NIGHT –1 CELL_SCORED

    01 Overnight cell scoring

    Before anything opens, every candidate cell in the market is scored and ranked by expected catch. We open the cell with the best ratio of reachable volume to cost, not the biggest one.

    • Business count and density inside the perimeter
    • Share without a website (the part reachable by phone and mail)
    • Recent saturation: cells touched within 90 days are excluded
  2. DAY 0 AUDITED + CONTACTED

    02 Audit, first touch, ads

    Every business in the cell is audited: 0–10 score, mobile load time, listing state, reviews and the three specific failures. With that, the first touch stops being an introduction and becomes a diagnosis.

    • Email to businesses with a site and a verified address
    • Geo-targeted ads over the same perimeter, from aggregate data only
    • Companies and sole proprietors separated before anything sends
  3. DAY +2 SIGNALLED → QUALIFIED

    03 Calls only on signal

    We dial the businesses that opened, clicked, scanned a QR code or visited. The call opens with their audit score, not with a script. Do-not-call registries are checked before any sole proprietor is dialed.

    • Call queue ordered by signal strength
    • Trade-specific calling windows: nobody calls a restaurant at noon
    • Every call outcome recorded as a logged transition
  4. DAY +7 POSTAL

    04 Printed mail

    The bulk of the cell, the businesses with no website, gets a letter with their own audit printed on it and a unique QR code. 100% deliverability and no competitor in that mailbox.

    • One QR per letter: replies attribute to the exact envelope
    • About €0.70 per letter, 2–4.4% reply rate
    • Print and postage handled end to end by us
  5. DAY +14 CLOSED + FEEDBACK

    05 Shut down, measure, feed back

    The cell closes. Cost per meeting and reply rate by channel are calculated, and that result becomes a weight in the next night's scoring: the system learns from the last cell before opening the next.

    • Real cost per meeting, by channel and by trade
    • Opt-outs and deferrals consolidated into global suppression
    • Cell archived with its full history
The five milestones of a cell cycle: on night −1 cells are scored and one is chosen; on day 0 the cell is audited, first contact goes out and ads are switched on; on day +2 calls go only to those who signalled; on day +7 a letter reaches those email cannot; and on day +14 it stops and cost per meeting is measured, which picks the next cell.
The axis below puts the days to scale: half the campaign happens between day +7 and day +14, even though the row above gives them equal space.

Which channel each business gets

The channel is set by what that business actually has, whatever our own preference. That is the difference between working a cell and burning a list.

Business situationChannelHookReference
No website, working phone Phone + printed mail Missing listing details and no site against direct competitors 30.9% of Spain
Website with verified email Email + follow-up Audit score and the three specific site failures 32.7% have email

The sequence lives in a state machine

No step depends on a language model remembering where it was. Each business's state lives in a database, every transition is logged, and the system is re-entrant: a crash mid-cell resumes exactly where it stopped. The model writes and classifies inside a state; it never decides the next state.

  1. CELL_SCORED cell chosen, budget assigned
  2. AUDITED score and failures per business
  3. CONTACTED send logged with legal basis
  4. SIGNALLED open, click, QR scan or visit
  5. QUALIFIED call with classified outcome
  6. MEETING / SUPPRESSED booked meeting or global opt-out
State machine diagram: CELL_SCORED, AUDITED, CONTACTED, SIGNALLED and QUALIFIED chained together, with two final exits branching from the last one: MEETING, a booked meeting, and SUPPRESSED, a global opt-out.
Both exits are legitimate endings. An opt-out, far from being a system failure, is the system complying with the rules, and it is recorded just like a meeting.

What you get during the cycle

D1

Meetings on your calendar

With the business name, its audit score, the channel it came in on, and what was said. No context-free leads.

D2

Live cell status

How many audited, contacted per channel, how many signals, how many opt-outs. One board, no jargon.

D3

Cost per meeting

Calculated on the week's real spend, channel by channel. It's the number you use to decide whether to scale or switch trade.

D4

Compliance record

Every send with its legal basis and data origin, plus the suppression list. Exportable if you get audited.

Questions that always come up

How many meetings does one cell produce?

It depends on cell size and trade. In continuous operation the target is 8–12 meetings a month with a new cell opened daily. A small cell of 150 businesses books fewer meetings but usually at a better cost per meeting, because the audit is sharper.

Why 14 days instead of an endless sequence?

Because past two weeks the marginal return on chasing drops below the return on opening a fresh cell, and because outreach that keeps calling after that stops being prospecting and starts being a nuisance. We shut it down, measure, and move.

Can you rerun a cell?

Yes, but not within 90 days, and never over businesses that opted out: suppression is global and permanent. On reopening, the audit is rebuilt from scratch, because sites and listings change.

What happens to "not right now"?

It's recorded as deferred with a date, drops out of the active campaign, and only re-enters if they named a specific time. An explicit no is treated as an opt-out.

Who talks to the business, you or us?

We do, up to the booked meeting: audit, first touch, qualifying call, confirmation. You show up to the meeting, which arrives with the business context and its audit score attached.

Shall we start with one cell?

Tell me the trade and the city and I will send back the real numbers for that cell before you commit to anything.
