Supply-path intelligence
See, control, and refine programmatic supply paths in flight.
Alargo maps live programmatic supply across publishers, SSPs, resellers, apps, and CTV, then turns that intelligence into approved buying controls for DV360, The Trade Desk, and real-time API workflows. Use it before launch to build cleaner supply plans, during flight to monitor path quality, and at bid time to help platforms make better supply decisions. The result: more Marketing Accepted Leads, higher CTR, more clicks and impressions, lower CPC, and dramatically reduced DSP warm-up time from days to a couple of hours.
Up to 40% of early-flight budget recovered from live activation: less warm-up waste, cleaner supply, faster first conversions.

DV360
The Trade DeskWhat Alargo does
The execution layer that turns programmatic supply intelligence into DV360, The Trade Desk, and API-ready controls.
-
01
Shows where your programmatic budget actually runs
-
02
Identifies inefficient, opaque, or off-brief supply paths
-
03
Recommends cleaner authorized alternatives
-
04
Writes approved controls back to DV360 and The Trade Desk
-
05
Gives DSPs and platforms API-ready supply-path decisions
The problem
Where did the money actually go?
Every supply path has different economics, transparency, and signal quality. A campaign can reach the same publisher through multiple authorized routes, but not every route delivers the same working media, visibility, or performance. The bid gets optimized; the path gets guessed.
DSPs optimize the bid. Alargo helps optimize the path.
When it works
Before launch. During flight. Before the bid.
Pre-flight
Build verified publisher, app, SSP, format, and path controls before launch.
In-flight
Monitor delivery and write approved adjustments when supply mix changes.
API
Score supply paths for DSPs, SSPs, and platforms before or during decisioning.
The graph
The ground truth of open programmatic.
Alargo maps programmatic supply across 122,000 publishers, 10,000+ SSPs, and 174M supply-path edges spanning web, app, and CTV. Reseller hops and verified direct alternatives, cross-checked from two independent sources: publisher ads.txt and SSP sellers.json. Two-sided verification, self-maintaining through continuous crawling, so it stays current.
Bi-directional DSP
Not another report. A control surface for programmatic supply.
Alargo connects to DV360 and The Trade Desk workflows to read campaign delivery, identify inefficient or risky supply paths, and write approved changes back into the platforms buyers already use. Alargo is the supply-path control layer between your media plan and your DSP: the DSP decides how much to bid, Alargo helps decide which supply paths are worth bidding on.
Pull campaign data from DV360 and The Trade Desk. See hop depth, reseller chains, MFA exposure, suspicious inventory, format concentration, and drift from the plan.
Find the publishers, app bundles, SSPs, and supply paths to keep, cut, replace, or review.
Push approved supply controls back into DV360 and The Trade Desk, including allowlists, exclusions, verified supply packages, and Blue List workflows.
Every action is human-approved, reversible, and audit-logged.
Performance
Cleaner paths create more working media.
Across live DSP campaign analysis, Alargo has identified material efficiency gains by moving spend away from inefficient, opaque, or off-brief supply paths and toward verified, higher-quality alternatives.

Results vary by campaign, DSP, supply mix, and activation method. Metrics based on live campaign analysis and/or customer pilot data.
The DSP optimizes the bid. Alargo optimizes the path.
The API
Supply-path decisioning at bid time.
The same graph, exposed to DSPs, SSPs, agencies, and platforms for verification, scoring, monitoring, and decisioning. Every incoming supply chain validated against the two-sided graph with an in-memory hot path, fast enough to sit inline in the bidding loop. Returns a clean / unauthorized / suspect verdict per node plus a completeness score. Unknown publishers enqueue for background crawling, so coverage compounds with every request. Auth per key, rate-limited, audit-logged.
{ "completeness": 1.0, "nodes": [ { "sid": "pub-3391", "verdict": "clean" }, { "sid": "ssp-0088", "verdict": "clean" }, { "sid": "rsl-4420", "verdict": "unauthorized" } ], "enqueued": [] }
The ecosystem
Built for the entire programmatic ecosystem.
Alargo is not a DSP, SSP, exchange, or media seller. It's an independent supply-path intelligence layer that helps buyers, DSPs, SSPs, and publishers understand how supply is represented, routed, and optimized.
For buyers
Better campaign control, cleaner working media, and paths you can defend to clients.
For DSPs
Real-time supply-path intelligence to enrich bidding, verification, and optimization.
For SSPs
Surface direct coverage gaps, competitive overlap, and where higher-quality supply relationships win more demand.
Tool Factory
Governed AI agents over your data, without engineering.
Describe a question in plain English. Tool Factory generates the governed tool: SQL, Python, schema, tests, against your source. You approve it, and it publishes to an MCP endpoint your chat or agent calls with one key. The agent never sees a row, query, or connection string. Per-customer key grouping, full call logging, PII-safe by design.
Who it's for
Built for the people writing the check.
Alargo gives your team the supply-path intelligence their DSP doesn't have, and the audit trail their CFO is asking for.
