Plenum by Pentane
Meta and Google get more crowded every quarter. Plenum routes your budget into the channels big brands have always had — display, video, premium CTV, audio, native and DOOH — and reports every dollar back against your real contribution profit.
$3,000/mo minimum media budget. No platform fee, no retainer.
The outcome
“Contribution-profit growth materially exceeded the increase in spend.”
Every extra dollar of ad spend came with about $2.86 of extra contribution profit. One client, one month.
Plenum ran $20,438 of that budget — 13% of total media. Every placement reported back by name.
On connected TV: The Roku Channel, Samsung TV Plus, Telly, Estrella TV, Watch Free and 53 others.
Not a separate login or another dashboard to learn. Spend, delivery and results land in the same account as your P&L.
The problem
A 3.2 ROAS means nothing if your breakeven is 3.5. Pentane exists because platform-reported numbers aren't profit.
CTV, video, native, audio and DOOH sit underused — locked behind contracts, minimums and seats most brands can't justify alone.
Fix one without the other and you've just moved the problem.
What's included
Your ad on the news and content sites your customers already read.
A recommended-story unit that matches the site it sits on.
A pre-roll spot before the videos they are already watching.
A TV spot inside the streaming they already pay for — Netflix, Disney+, Hulu, Prime Video.
A thirty-second spot on Spotify, Pandora and the podcasts they listen to.
Digital billboards, gym screens and pump-top displays near your buyers.
Ad platforms are places to buy media. Plenum is the system that decides whether buying there was worth it — then acts on the answer.
Upload emails, postal addresses or phone numbers. They are matched securely to digital IDs, then reachable on connected TV, display, mobile, audio and video — the same people, off Meta.
Optimisation runs off your actual contribution margin — order data, COGS, shipping, discounts, refunds — not off platform-reported conversions. Plus 1,000,000+ audience segments from 50+ data providers.
Beacon, our automation layer, proposes the campaign changes it thinks the numbers justify. A named person approves them. Only then do they execute — with a full audit trail of who changed what, and why.
A network optimises itself. We decide how much belongs on each one — display, CTV, audio, native, DOOH, Meta — based on which actually earned margin, and move budget accordingly.
What you can reach
Netflix. Disney+. Spotify. The inventory that normally takes an agency contract and a five-figure minimum — reachable from a $3,000 monthly budget.
Routed across 12 DSPs — Amazon DSP, DV360, Criteo, Magnite, Viant, Yahoo, Moloco, Beeswax, MediaMath, Smadex, Vistar, Broadsign. We don't own any of it, so our incentive is your best blended outcome rather than any one network's share of your wallet.
