Autonomous cross-channel ad buyer

Stays on the budget.
Stays on the brief.
Shows its work.

Plumbmark is always on — it watches Google, Meta, and TikTok around the clock and reallocates spend toward the highest-returning initiatives within the guardrails your team sets. Every move is recorded to a reversible ledger — timestamp, inputs, the threshold that triggered it, and the reasoning behind it. And every move is fully reversible: one click from the audit view, the rest of the day stays intact for finance to attest.

What Plumbmark does

Three things, every cycle.

The agent reallocates within rails your team sets, logs everything to a ledger your team can audit, and writes the morning brief before finance has opened the file.

Audit trail

Every move timestamped at write time, exported as a finance-grade CSV from the same store the on-screen audit view reads.

Guardrails

Floor ROAS, daily-change cap, allowed channels, kill threshold — each enforced as a hard constraint, with the declined decision logged.

Daily digest

Tomorrow's planned reallocations, scored, with the declines noted — the morning brief your team opens before finance does.
