For agencies

Run mid-market ad spend on the same autopilot your in-house team uses.

Plumbmark is the autonomous cross-channel ad buyer performance marketing agencies use for mid-market DTC and B2B portfolios. Google, Meta, and TikTok reallocate inside the per-portfolio policy file your team writes, every fifteen minutes — built for three pillars an agency actually cares about: multi-client audit logs your finance reviewer can attest, per-client guardrails that hold your negotiated ceiling, and a white-label-ready digest export the client reads without logging into Plumbmark.

How an agency portfolio runs on Plumbmark

Two placements, the same ledger.

Placeholder scenarios from a DTC and a B2B SaaS portfolio — the same multi-client audit logs, the same per-client guardrails, and the same white-label-ready digest export your client receives on Monday morning.

DTC · placeholder case study · $1.2M / quarter · US + DE
  • Spring Lookalike US carried a 2.1× ROAS; Plumbmark reallocated 18% of spend across to the DE lookalike set the week DE passed the floor — written line-by-line to the per-client ledger.
  • Daily-change ceiling kept the TikTok retargeting set from spending more than $4k even as the afternoon return-on-spend curve looked promising — held the policy rail, missed the spike.
  • Client review CSV arrived Monday morning, six rows, one rebalance, no meeting.

B2B SaaS · placeholder case study · $680k / quarter · ABM-led
  • Floor ROAS on Google Brand Search held the bid flat across two weekly competitor eruptions while LinkedIn lead-form took the reallocatable envelope; finance asked why brand-search dipped, the ledger answered in two rows.
  • ABM pipeline narrative attached: every LinkedIn lead landed with a `source = plumbmark_reallocation` row the sales team could attribute end-to-end.
  • Whitelabel digest sent to the client CMO every Friday — same row shape as the marked-up cover-sheet the agency partner used for the kickoff.

Why this lands for the operator

One page, every morning, already read.

You used to start the week by stitching together four platform exports, cross-referencing slack threads, and re-reading the kickoff brief for what was promised. The Monday-morning standup was a recap of yesterday, built from memory.

With Plumbmark, Monday morning is one page. The agent ran the cross-channel loop every fifteen minutes overnight; the prior UTC day's moves, the channel balance, and the campaigns the buyer paused are already on a dated digest. You read what happened, you pull the levers the policy file left for you, and you walk into the client meeting with the answer already on paper.

The same cover-sheet your senior reviewer sees is the live digest — for operators who want to open it, pick a date, and read the moves behind it.

How it runs. How it compares.

The same cadence your client reviews against — and the same ledger, walked side-by-side against the alternatives the market-research brief names.
