Our mission
Make every media dollar work harder.
Agency buyers deserve to know where their spend goes. We built Alargo to surface the truth before money changes hands, so you can buy more efficiently and defend every decision.
The challenge
Death by a thousand cuts.
No single inefficiency kills a campaign. But they add up.
What agency buyers face today
The result
You're losing 3% here, 5% there, across thousands of auctions. Indirect paths inflate CPMs. Slower bids lose auctions. Budget that could buy 10M impressions only delivers 7M.
Your $1M campaign performs like $700K, and nobody can explain why.
Neutral by design.
Alargo is not a DSP or SSP. We're the verification layer that sits outside the transaction, exposing path efficiency so you can enforce cleaner supply and improve outcomes.
The team
Built by ad tech veterans.
20+ years building the infrastructure that powers digital advertising.
AWS (Amazon Web Services)
Built initial narrative that became AWS RTB Fabric. Worked with enterprise clients like P&G, CBS, Sony Pictures, and Warner Bros Discovery on $400M+ platform evaluations.
Fox / Paramount / Disney
Oversaw $1.5 billion in programmatic ad operations. Optimized ad tech stacks and business intelligence platforms at scale.
Hulu
Led core platform engineering initiatives and managed large-scale systems at the intersection of technology and media monetization.
Omnicom / P&G / Gannett
Deep experience on both buy-side and sell-side. Multiple patents in ad tech innovation, RTB, and large-scale infrastructure.
"After 20+ years watching agency teams struggle with opaque platforms and unverifiable spend, we built the supply-path verification layer we wish had existed all along. Buyers deserve to see where money actually flows, without bias, without conflicts."
— Alargo Founders
The platform
A verification layer for media buyers.
Not another dashboard. A system that validates supply efficiency and makes it enforceable.
Supply Graph
Data sourced from verified, monetized, programmatic-eligible publisher inventory. Updated daily. Supply paths across 10,000+ SSPs, including Google, PubMatic, OpenX, Index Exchange, and more.
122,000+ verified publisher domains
Continuously refreshed
Path-level visibility
Direct + reseller chains
Path Efficiency Analysis
See which paths are direct vs. indirect. Identify where fees stack up. Separate efficient routes from wasteful ones before spend flows.
DSP-Ready Write-Back
Push verified allowlists back into the buying systems your team already uses, so "efficient supply" becomes an enforced policy, not a hope.

Continuous Monitoring
Supply changes mid-flight. Alargo detects when paths change, new resellers appear, or authorization shifts, so your rules stay true throughout the campaign.
Alert on drift
Changes to authorization, seller identities, and route composition
The result: more efficient paths, lower effective CPMs, and better outcomes you can defend to clients.
