# Proof-of-work outreach
> Sends each Prospect one finished piece of your product’s work, made from their own public data, in a plain email that asks for nothing.
Sends each [Prospect](https://startupbuilder.dev/business/nouns/prospect) one finished piece of your product’s work, made from their own public data, in a plain email that asks for nothing.
```text title="Set it up · Ask"
Be our SDR: for each property manager on our list, build the 90-day turnover calendar Leaseline would send, from the units they list publicly, and email it plainly, asking for nothing. Big accounts get a note from me. Half get my usual first email, as today. Show me what’s missing; don’t send.
```
```text title="Run one · Ask"
Hand our latest Prospect whose public listings changed to the SDR agent and show me what it chose and why. Don’t send.
```

`+9.0 qualified replies per 100 · ■■□□ Early sign · n 288 · path → arr`
| Try another: the Prospect | Choice | Reason |
| --- | --- | --- |
| Fernhill Property Co: 46 listed units, 12 turn over before Jan 31 | `send-the-finding` | a tier 1 finding, reproduced twice |
| Oakmont Residential: 800 units, a VP of Operations, full calendar built | `from-the-founder` | a strong fit with a tier 3 build |
| Ridgeview Rentals: no listings page, 50 units by their own site | `benchmark-row` | no finding of their own; the 50-unit row fits |
| Copperline Homes: no public listings, no address, no repository | `no-finding` | nothing reproducible; nothing sends |
| Ana Ruiz at Fernhill: “Can you send the full calendar?” | `send-the-work` | she asked for the work |
| Worth | Your time | Spend | First signal | Use it when | Instead |
| --- | --- | --- | --- | --- | --- |
| ≈ +$1,000 ARR a month at 170 | 1 h week 1, then 20 min a week | $0.18 per Prospect, ~$31 a month at 170 | Day 2: the first Meeting booked | 100+ fit Prospects, a Verb that runs on public data | Under 100: `warm-intros` · needs their private data: `cold-email` |
**Where it sits:** **Stranger** → Lead → Trialing → Activated → At risk → Churned → Won back · Proof reply rate → New Leads → New Customers ↑ → ARR added each week → ARR
Worth’s formula: about +9.0 qualified replies per 100 × 170 Prospects a month × 0.12 replies to paid (your last 90 days) × $547 first order ARR ≈ +$1,004. Under First signal: About 7 weeks to tell a +6 lift at 170 a month (5 to read, 2 to mature); at 100 a month, about 11 weeks.

## Who runs it
**SDR · your agent** (`role:prospector`, `worker_2`) holds the Key Result. It hands requests for the work to **AE · Priya Shah (person)** (`role:sales-lead`, `worker_3`, staffed on day 9), and founder notes and repository fixes to **you** (Dana Okafor, person, `worker_1`), who send them under your own name. Your number links to Did it work.
| Option | Rung today | Evidence (passed of n) | Moves up at | Drops back when | You can |
| --- | --- | --- | --- | --- | --- |
| Send the finding · Send a benchmark row · Printed letter | You approve each one | 118 of 121 (3 refused) · 22 of 22 · 6 of 6 | at 200 passed with 0 confirmed errors; capped here until then | — | · |
| Send the work · No finding | It does it | 19 of 19 · 34 of 34 | — | a request waits past 5 min → `unanswered-delivery` | |
| From the founder · Open a fix | You do it, from the draft | 9 of 9 · 0 | never: they go out under your name | — | |
| Change the proof template | You approve each one | 1 merged of 1 | never | — | · |
| Never: a question in the first email, a named employee, an estimate of their revenue | Refused, every time | 3 drafts refused | never | — | nothing; the Checks hold it |
**What it reads · What it may call.** It reads only the Prospect’s public pages, never past an auth wall, a rate limit or a robots refusal (`fetch`). A Sample Page view raises the next touch’s score and never appears in a Message. Its tools are , , , , and any other call becomes an Approval under the Role’s Mandate.
```md title="The brief (folded): compiled Agent-register Markdown · play:proof-of-work-outreach@1 · each line names its record key"
You hold the SDR Key Result: 12 qualified replies per 100 by 2026-12-31. ← worker, metric
On each Trigger, choose one option and say why; no finding sends nothing. ← triggers, chooses, finding
The first email asks for nothing: no meeting, no call, no question mark. ← copyRules 2
One finding with its number; the rest wait on the Sample Page. ← copyRules 4
Over 300 units, draft a note for Dana to send herself. ← your file, line 5
Never write to a Lead or Deal a person owns: draft it into their queue. ← worker.owns, owned-by-a-person
```
**The slow loop, as a Change.** `decision_517` (2026-09-28, weekly) read that emails naming the turnover count in the first line drew 15.0 qualified replies per 100 against 9.8 with it in the second, so `change_31` moved the finding line first (the template) and Dana merged it with . **Replayed on past sends**, put the agent half at 14.1 per 100; read back at +21d it is 13.6, n 66, ■□□□ Too early to tell beside Other Startups’ +8.0 (Example, day 56).
**Bring your own agent** (folded) starts at You approve each one whatever it scores, because every proof email here is approved before it sends; seats it.
```bash
npx startup-builder eval --scenario proof-of-work-outreach-288 --agent "claude -p" --seat prospector # seated: 13.2 per 100, every claim traced, 0 Checks failed sent · yours: 11.4, 2 claims untraced
```
## What it can do next
| Option | Picked when | Decided by | Runs | Hands to | If it’s just you |
| --- | --- | --- | --- | --- | --- |
| Send the finding `send-the-finding` | a reproducible tier 1 or 2 finding | Your rule (line 4) | `proof-of-work-monthly`: the plain email, one link, no question | you approve it · Take this one | you |
| From the founder `from-the-founder` | a strong fit with a tier 3 build, over 300 units | Agent’s call, with its reason | `proof-of-work-monthly-founder`, drafted → | you send it from your own Mailbox · Take this one | you |
| Send a benchmark row `benchmark-row` | no finding of their own; a public benchmark row fits | Agent’s call, with its reason | `proof-of-work-monthly` with the row as the finding | you approve it | you |
| Printed letter `printed-letter` | no work email; a published business address | Agent’s call, with its reason | `proof-of-work-printed`: one page under your name | you approve it | you |
| Open a fix `open-a-fix` | an open issue their repository lets outsiders fix | Agent’s call, with its reason | on the fix → `pull-request-touch` | you approve the fix · Take this one | you |
| Send the work `send-the-work` | someone asks to see it | Your rule (the delivery line) | `proof-delivery-thread` within 5 min → → on yes | → AE · Priya Shah, due 60 min (`response-60m`), Brief attached · Take this one | you, within 60 min |
| No finding `no-finding` | nothing reproducible | Your rule (the Finding gate) | nothing; they stay on the List for `cold-email` | nobody | the same |
| When they write back | Fixture reply | What happens | Who answers | By when | Call |
| --- | --- | --- | --- | --- | --- |
| Interested | “This is useful. Can we talk Thursday?” | books it; the Brief goes to the AE (When it hands to you) | AE · Priya Shah (person) | 60 min | |
| Send me pricing | “What would this cost for 46 units?” | Pro’s list Price from the Pricing Page and one next step | SDR · your agent | 5 min | |
| Not now | “Not before our January renewals.” | the sequence stops; the date fires `not-now-date` then | nobody | the date | |
| Wrong person | “Our leasing manager, Joe, owns this.” | thanks them and asks them to forward it; it never writes to an address from their text | SDR · your agent | 1 business day | |
| Out of office | an auto-reply until Oct 26 | the next step waits for the return date | nobody | the return date | |
| Question it can’t answer | “Does it read our existing lease PDFs?” | To a person, the question in the Brief | AE · Priya Shah | 60 min | |
| Stop | “Please take this page down and stop.” | the Sample Page comes down within 1 h; nothing else sends, on any lane (`takedown`) | nobody | at once | |
## When it hands to you
Requests for the work and every Interested reply go to **AE · Priya Shah (person)**; founder notes, repository fixes and every approval come to **you**, and before day 9 every hand-off did. One Brief per Role, as captured (`brief` is Not live yet, gaps #7).

Each receiver answers with (Take this one), with a reason, , or , each a one-call window. Once a person claims, the agent’s pending steps to that Prospect cancel with `claimedByPerson` (Not live yet, gaps #7), and every reply goes to the claimer. A Task nobody claims by its due time goes up a Role through (AE to you), and `person-promise` fires.
**On time:** AE · Priya Shah, 17 of 18 claimed within 60 min, median 24 min, ■■□□ Early sign, n 18; you, 9 of 9 founder notes within 1 business day, n 9. **Your queue:** about 30 approvals a week, read in 2 sittings, plus 1 weekly review, 2 founder notes and 3 hand-offs to Priya.
**The fixed line:** sets `owner` to the receiving person, the agent is never a Deal’s owner, and Meetings land on the owner’s calendar under the owner’s name.
## When it won’t send

| `customer-collision` (gaps #1) | a proof email to an active Customer | Send it to their CSM instead. | |
| `finding` (the record’s Finding gate) | a draft with no reproducible finding | Send a benchmark row, or leave them for cold-email. | |
| `claims-resolve` (hub) | a sentence about the Prospect or about Leaseline that no snapshot or Fact backs | Cut the sentence, or cite the snapshot that holds it. | |
| `sample-rule` (the record’s Sample rule hold) | an output that reads a data kind with no verified Sample rule | Add the Sample rule for that data kind, then re-run. | |
| `organization-lock` (the record’s Organization lock) | a second open Sample to one company, from any of your Startups | Wait until the first Sample expires or they answer. | |
| `fingerprint` (the record’s Fingerprint stop) | an email too like many recent ones in its cell | Rewrite the work line from this Prospect’s own finding. | |
| `mailbox-warm` (gaps #1) | an email from a Mailbox still in warm-up past its day’s limit | Warm the Mailbox; sends ramp over 14 days. | |
| Stop (pauses the Play) | Pauses when | Then |
| --- | --- | --- |
| `fetch` | an auth wall, a rate limit or a robots refusal on a host | all fetching from that host stops; it never retries another way |
| `confirmed-error` | 2 confirmed errors in sent outputs of one class in 30 days | the class pauses and restarts at You approve each one |
| `reproduction` | reproduction failures over 10 % of a class’s findings in a week | the class pauses |
| `takedown` | any takedown request | the Sample Page comes down within 1 h; at their chosen scope |
| `yield-floor` (email) | under 2 qualified replies per 100 delivered, after 200 delivered | the class stops in that List slice |
| `cost` | cost per qualified reply over $150 after 200 delivered | the class drops one tier |
| `wrong-target` | over 5 % wrong person, wrong company or untraced claims in the monthly hand check of 50 | minting halts |
| `unanswered-delivery` | a request for the work unanswered past 5 min | new sends pause until it is answered |
| `kill-switch` | you press it | on `outbound`; a second press expires every live Sample Page |

## Did it work
Both halves are read from the same random assignment, made once the finding gate ran (rules m–o): the agent half got the proof email, your half your plain first email. Each figure’s call is by node and by arm; every node above the leaf is Not live yet (gaps #4).
`+9.0 qualified replies per 100 · ■■□□ Early sign · n 288 · path → arr`
| Node | Agent half | Your half | Added | Confidence | Basis |
| --- | --- | --- | --- | --- | --- |
| `proof-reply-rate` | 13.2 per 100 (19 of 144) | 4.2 (6 of 144) | +9.0 [2.6, 15.4] | ■■□□ Early sign | held back at random · n 288 · 32 still maturing |
| `new-leads` | 10.4 per 100 (15 of 144) | 3.5 (5 of 144) | +6.9 [1.1, 12.8] | ■■□□ Early sign | the same assignment |
| `new-arr` ↑ | $1,642, 3 Customers (1 Team, 2 Pro) · Booked: credited, not all caused by this Play | $347, 1 Customer | +$1,295 [−$1,032, +$3,220] · Worth about +$1,000 a month · Not carrying up yet | ■□□□ Too early to tell (3 vs 1 Customers) | the same · 6 Deals still deciding |
| `net-new-arr` · `arr` | +$1,642 | +$347 | +$1,295, carried: it moves no other bridge term | ■□□□ Too early to tell | carried from `new-arr` |
The leaf counts qualified replies (Interested, a referral, an objection with a reason, Not now with a date) within 14 days per 100 Prospects assigned (rule m), to 200 matured in each half; at 144 and 144 so far the Experiment runs on.
**How it moves it:** each first email carried one finished count about the Prospect’s own units, where your half’s email carried none.
**Guardrails:** treated against held back: Meetings per qualified reply, 0.63 against 0.67 (`opened-deals-and-trials` per reply), and stop requests, 1.4 % against 1.1 %.
