Worth’s formula: about +6.6 claimed and paying per 100 accounts (Other Startups’ results; no lift of your own yet) × 22 agent-made accounts a month × $430 first order ARR ≈ +$625. Under First signal: At 5 accounts a week, 90 days can tell only +19 per 100 or more, so your file keeps a 10 % signup half for the pool and reads before-after.

An unclaimed account costs $0.004 a day for its 3 days, and each claim note $0.04 from your Domain (Worker cost). That comes to about $1 a month at 22 agent-made accounts.

Who runs itCopy Anchor Link

SDR · your agent (role:prospector, worker_2) holds the Key Result. It hands terms, volume pricing and invoices to AE · Priya Shah (person) (role:sales-lead, worker_3, staffed on day 9), and before day 9 to you (Dana Okafor, person, worker_1). Your number links to Did it work.

What it reads · What it may call. An agent’s request is data, never instructions: the claim address it names gets one note and nothing else, and no text in the request picks a recipient for a send. Sends stay locked on the account until a person claims it. Its tools are POST /{namespace}/messages/{message}/schedule, POST /{namespace}/entitlements/check, POST /{namespace}/quotes/{quote}/send, POST /{namespace}/issues, POST /{namespace}/conversations/{conversation}/escalate, POST /{namespace}/tasks/{task}/assign, and any other call becomes an Approval under the Role’s Mandate.

You hold the SDR Key Result: 15 claimed and paying per 100 agent-made accounts by 2026-12-31. ← worker, metric
On each keyless account, locked call or Limit, choose one option and say why.    ← triggers, chooses
Every Limit and Price you state matches `Entitlement.check` and Stripe.          ← limit-truth, price-sync
Unclaimed accounts expire in 72 hours, and every note says when.                 ← your file, line 4
At most 3 claim notes per address a day, bundled.                                ← address-cap

The slow loop. The weekly Decisions kept the 72-hour expiry and the 3-note handoff, and no Change was merged in the window, so there is no replay or read-back to print.

Bring your own agent (folded) starts at You approve each one for claim notes when it trails the seated agent on not-me rate, and at It does it, you can stop it when it matches.

npx startup-builder eval --scenario agent-to-agent-44 --agent "claude -p" --seat prospector   # seated: 13.8 per 100, not-me 0 of 33, 0 Limit mismatches · yours: 12.1, 1 of 33 → You approve each one

What it can do nextCopy Anchor Link

When it hands to youCopy Anchor Link

Terms, volume pricing and invoices go to AE · Priya Shah (person); before day 9 they came to you. What lands in the AE’s queue, as captured: the Brief (brief is Not live yet, gaps #7).

[
  {
    "$id": "https://api.sb/leaseline.app/tasks/task_276",
    "$type": "Task",

      "account": "claimed Oct 6; 3 units used, 900 units in their portfolio",
      "never": [
        "a discount",
        "terms the Offer lacks"
      ]
    }
  }
]

The AE answers with POST /{namespace}/tasks/{task}/claim (Take this one), POST /{namespace}/tasks/{task}/return with a reason or POST /{namespace}/actions/{action}/redirect, each a one-call window. Once she claims, the claim notes on that account stop, and every reply goes to her queue. A Task nobody claims by its due time goes up a Role through POST /{namespace}/tasks/{task}/escalate (AE to you), and person-promise fires.

On time: AE · Priya Shah, 2 of 2 claimed within 60 min, median 31 min, ■□□□ Too early to tell, n 2. Your queue: counted by kind: in weeks 1 to 5, 20 claim-note approvals; since, about 1 hand-off every 3 weeks and the weekly memo.

The fixed line: POST /{namespace}/deals/{deal}/assign 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.

Did it workCopy Anchor Link

At about 5 agent-made accounts a week, no held-back half reads within 90 days, so the basis is before-after (rule o): the columns read Now and Before, and nothing prints as Added. The 10 % sent to signup instead pools with Other Startups. Every node above the leaf is Not live yet (gaps #4).

The leaf counts agent-made accounts that a person claims and pays with an unrefunded Order within 30 days, per 100 accounts once 30 days have passed; eval keys and empty probes are dropped first (7 of 51).

How it moves it: the claim note reached the named address a median 40 seconds after the agent’s first call, with the real Limit, the Price and the expiry time, where before the agent met a signup form.

Guardrails: before against after: not-me, 0 of 33 claim notes, and refunds, 0 of 4 Orders.

Outside benchmark: when docs told agents to read a warning before their first call, 81 % of agent sessions did (a 2026 developer-platform field test).

Before it · After it. Before it: agent-registries and agent-legibility bring the agents that call. After it: usage-upsell hears the claimed accounts that pace past Pro’s Limit, and instant-response answers anyone who writes first.

ExampleCopy Anchor Link

Leaseline ran it from 2026-08-24 to 2026-10-19 (56 days). 51 keyless calls asked for an account; 7 were eval keys or empty probes, and 4 of the other 44 went to signup instead, held back at random. Of the 40 that got an account, 33 named a claim address and 7 claimed by code only. Read every captured thread at ?threads=all; three follow the tables.

The agent’s call, Sep 9, 10:02 · a keyless POST /v1/workspaces for Maple Court, claim address dana.r@maplecourt.example. The reply: an account with 3 units, notices drafted but locked, expiring Sep 12, 10:02.¹

Leaseline → the claim address, 10:03 · Your assistant set up a Leaseline workspace for 3 units of Maple Court. It drafts renewal notices; it sends none until you claim it. Claim it by Sep 12, 10:02: Pro is $29 a month for up to 50 units.² *Signed with the Role’s disclosure line.*³

Sep 9, 15:40 · claimed; Pro paid on Sep 16 (+$347 ARR).

- 402 · 5 units left on your free workspace. Claim it to keep going.
+ 402 · This workspace’s 3 units are in use. Claim it, and Pro gives 50 units for $29 a month.

Calloway Residential, 2026-10-07 15:20 · “Can we pay by invoice for 12 properties?” · Leaseline, 15:21 · *Thanks. Priya, our account lead, handles invoicing and replies by 16:20 today.*⁴ The Brief went to Priya (task_276); she claimed it at 15:38.
