Garbage.

We know what DSPs are really looking for when they come to a low-CPM SSP. Let's not pretend otherwise. LowBid is honest inventory with honest economics.

Remnant & long-tail inventory

Thousands of publishers selling what the premium networks ignore. Undervalued, consistent, available.

What LowBid
Actually Gives You

No enterprise feature theatre. Six things that matter for a DSP buying low-CPM supply at scale.

OpenRTB 2.6 Endpoint

Standard bid request structure. Your bidder connects in under a day. We don't reinvent the protocol.

Domain-level control

Block lists, allowlists, category filters. You decide which domains get through to your budget.

Live bid analytics

Win rate, timeout rate, bid density — all real-time. No 24-hour lag on data you act on today.

Floor price optimizer

Dynamic floor prices per placement based on historical win data. Not static. Not guesswork.

Multi-DSP arbitrage

Run multiple demand sources against the same inventory. Best price wins, always. No preferential routing.

Billing transparency

Line-item invoices. No mystery fees. Revenue share spelled out in plain text in the contract.

Who Actually
Uses LowBid

Predominantly in-app and SmartTV inventory. Built for buyers who optimise on post-view metrics.

Performance buyers

You optimise on post-view conversions and ROAS, not clicks. In-app and SmartTV placements — your bidder scores on impressions and downstream signals.

Primary audience

Arbitrage teams

You buy cheap in-app and CTV supply, add targeting layers, then resell at margin. Scale and low floors matter more than brand safety labels.

Best fit

Reach maximisers

Reach and frequency campaigns on in-app and SmartTV. GEO coverage and impression volume at minimal CPM.

Good fit

How It Works

From zero to running bids in under 48 hours. No sales call required.

01
Step one

Submit your DSP endpoint

Send us your OpenRTB 2.6 bid endpoint URL, supported ad formats, and GEOs. That's the start of the integration form. Takes 3 minutes.

02
Step two

Set your floor tolerance and blocklists

Tell us your hard limits — domains you won't touch, verticals you avoid, minimum quality signals you need. We configure the filter layer.

Step three

Test traffic slice

We route 5% of available inventory to your bidder first. You check win rates, logs, and domain distribution. No spend until you're comfortable.

04
