The independent layer for programmatic trading

Know what actually works. Let the busywork run itself.

PlumSignal sits above your DSPs and turns every campaign into a clear read on what really drives value — which placements, audiences and frequencies pay off, and which quietly burn budget. A trading agent takes the daily grind off your desk, so your traders spend their time on decisions. And because it's independent, what you learn stays yours as agencies and DSPs change.

Every campaign sharpens the picture of what works — and it holds, whoever's in the seat

Clicks aren't customers. Last-touch isn't truth. Most of what looks like performance isn't.

The signal that actually predicts value — which placements, audiences and frequencies grow the business — is buried under vanity metrics and scattered across DSPs, dashboards and people who move on. So the real lessons get relearned, campaign after campaign.

The programmatic playbook

Everything that's
proven to work.

The distilled record of what's actually worked for your brand — proven inventory, audiences and tactics — primed from your history and refreshed by every campaign. Decisions start from evidence, and whoever runs the account starts from proven performers, not a blank sheet.

Accumulating brand assets

Assets that compound.

The longer PlumSignal runs, the harder it is to replace. Six models sharpen with every impression — and none of them reset when the team does.

01 · Saturation curve

Where frequency stops working

The marginal lift of the nth exposure — so you find the point where reach stops converting and starts burning budget.

02 · Divergence map

Click signal vs net value

Find where the clicks point one way and true customer value points the other — by supply path, creative and audience — then bid accordingly.

03 · Time-to-conversion

Not yet, or never?

The real distribution of time from first touch to purchase — so you keep exposing the people who are still deciding, and stop wasting the rest.

04 · Purchase cycle

When to re-engage a buyer

Built from repeat buyers — so you suppress someone who just bought, and return exactly when they're ready to buy again.

05 · Incremental value

Uplift, net of the inevitable

Predict the true lift of each exposure — net of the people who would have converted anyway — using history and live holdout arms.

06 · Lookalikes

Model your best — and your worst

Prospect from your highest net-value customers, and build suppression from the toxic ones. Careful never to exclude the quiet movers.

Deterministic brand audiences

Built on first-party identity, matchable to your CRM.

Audiences modelled on hashed-email identity — including suppression lists of the refunds, fraud and low-value users you shouldn't pay to reach. Not just whether to bid on someone, but what to say when you do.

The trading agent

Give your desk a trader
that never sleeps.

It connects to your DSP over MCP, pulls campaign statistics every hour, and turns them into concrete optimisation moves your trader approves with a click. It plans campaigns against your objectives, watches pacing and performance around the clock, and flags what needs a human. The repetitive work is handled — so your traders spend their time on strategy and clients, not spreadsheets.

Pulls & proposes

Hourly, over MCP

Connects straight to your DSP and reads performance every hour, then queues specific moves — shift budget here, cap frequency there, pause that placement — each with the numbers behind it, for one-click review.

Plans & paces

Runs the daily grind

Builds media plans against your objectives, then watches pacing, supply and delivery around the clock — catching under-delivery, budget drift and broken placements between your check-ins.

Sharpens over time

Grows with your book

Every campaign sharpens the models behind it, so the agent's calls get better the longer it runs — the same playbook across every seat, and never an off day.

Human-in-the-loop by design — the agent recommends, your team decides, and nothing changes unattended. For an agency that's pure leverage: the repetitive optimisation, monitoring and reporting comes off the desk, your traders punch above their level, and every seat gets covered without cutting corners.

Beyond the models & the agent

Everything the layer does.

Supplier audit

An independent check on what you're really buying — and what each layer of the supply chain is really taking. Third-party truth injected into every buy, so you can trust the numbers your partners report.

Panels · Fraud · Take rates · SPO · Benchmarks
  • Third-party validation — inject measurement panels, fraud and viewability detection into live buys.
  • Industry benchmarks — compare performance against relevant norms, not just your own history.
  • Take-rate X-ray — estimate and visualise effective media spend: how much actually reaches inventory.
  • SPO route analysis — compare competing paths to the same impression and pick the most efficient.
  • Full audit trail — a high-level log of account activity and every action taken.

Campaign insights

Every campaign, every partner, read in one place — so you see what's actually working across the whole account, not one DSP's slice of it. Creative, media, channels and pacing, in a single view.

Incrementality · Creative · Media · Channels · Pacing
  • Incrementality & true reach — incremental-gain analysis with unique reach and real frequency.
  • Creative intelligence — fatigue by name, format and content; static vs animated; best and worst formats.
  • Media mix — deal versus open-market performance, and which deals are carrying or dragging.
  • Channel balance — web, app, CTV, in-stream, out-stream and DOOH, weighed against goals.
  • Quality — ads.txt inventory checks and fraud analysis across the buy.
  • Pacing & supply — delivery by weekday and hour of day, with geo and audience cuts.
