Bullpen

For sponsorship & partnership teams

Three agents that run the whole play on a sponsorship.

Scout finds the brand. Closer drafts the proposal. Recap proves the deal out at renewal. Every number traces to a source, every claim gets a human review before it ships.

The problem

Sponsorship sales runs on paperwork nobody has time for.

01

Prospecting takes days, not deals

Building a credible list of sponsorship prospects means hours of research per brand, and most of it is guesswork about fit and timing.

02

Proposals get generic, or slow

A tailored proposal — with real inventory, real pricing, real comps — takes a full day to build well. So teams reuse the last one instead.

03

Recaps are where trust is won or lost

The renewal conversation lives or dies on whether the numbers in the recap actually hold up. One inflated stat costs the whole account.

The roster

Three agents, same human-in-the-loop flow.

01 · Prospecting

The Scout

Turns a client profile into a ranked list of ~10–15 brand sponsorship prospects.

Every fact about a brand is researched live on the web and cited to the exact URL it came from — fit reasoning, timing, decision-maker, and a concrete first move for each one. Output is a single sendable brief.

02 · Proposals

The Closer

Turns a prospect brief, your inventory, and past-deal comps into a first-draft partnership proposal.

Every dollar figure traces to the rate card or a comp — package, valuation, activation ideas, and the timing case, ready for a rep to send with light edits.

03 · Renewals

The Recap

Turns campaign data and the original deal terms into a source-checked sponsorship recap.

Every number in the document is checked back against the model — the renewal conversation runs on numbers that actually hold up, not on what a rep hopes they'll be.

The guardrail

Three checks before anything ships.

The reason to trust a number in one of these documents isn’t that a model produced it — it’s that the run couldn’t finish if the number were wrong.

an unsourced claim can't parse

Code gate

every number recomputed, not guessed

Advisory flag

shaky claims flagged for review

Layer A

Schema

A factual sentence with no source can't parse. The model itself won't accept an unsourced claim.

Layer B

Code — the gate

Every cited source must exist. Every number in the document must equal a cited, code-computed value — not a model guess. A blocking violation stops the run before a document is written.

Layer C

Cheap model — advisory

A second, cheaper model flags shaky claims, thin evidence, or boilerplate reasoning as warnings for the human reviewer. It never passes or blocks a run on its own.

In practice, per agent

  • The ScoutEvery note URL's domain must appear in the research log the web step actually surfaced — a fabricated citation is blocked outright.
  • The CloserThe whole valuation — package, rate card, comps — survives a fresh recompute; each suggested range endpoint equals a code-computed anchor, not a model estimate.
  • The RecapEvery delivered number must equal a cited factbook value within ±0.5%, and media value must survive a fresh recompute.

How it works

Analyze. Review. Write. Every run, no exceptions.

1

Analyze

The agent builds a structured, validated model of the output — prospects, package, or recap — then stops. Nothing gets written yet.

2

You review

A plain-language review sheet with every QC flag up top. Edit the model directly, or fix the input and re-run analyze.

3

Write

Only once the model passes QC does the agent turn it into the final document — re-checking every number and citation one more time on the way out.

Human-in-the-loop by design — the agent never sends anything on its own. It hands you a document that’s already been checked, so your edit pass is about tone and judgment, not fact-checking.
