The Problem
Your Campaigns Are Leaking Money
Every unnecessary middleman in the supply chain inflates prices, slows down your bids, and reduces win rates. The result? Fewer impressions, fewer clicks, fewer conversions, for the same budget.
Inflated Prices
Indirect paths stack hidden fees. You pay more per impression than you should.
Lost Auctions
Longer paths mean slower bids. You lose premium inventory to faster buyers.
Wasted Budget
Budget that could buy 10M impressions only delivers 7M. Performance suffers.
The Solution

Business Outcomes
What Changes When You Use Alargo
We operate upstream of performance, where efficiency is determined.
Lower CAC
More efficient paths mean lower cost per acquisition across campaigns.
Higher ROAS
Same spend, more conversions. Better return on every dollar.
Win More Bids
Direct paths are faster. Faster bids win more premium inventory.
Defend Results
Show clients exactly why performance improved. Evidence, not excuses.
Example: Mortgage Campaign
Same $1M Budget. More Applications.
A bank running mortgage ads through indirect paths pays inflated prices and loses auctions to faster buyers. Fewer impressions means fewer clicks, which means fewer applications.
With Alargo: Cleaner paths → lower prices → higher win rates → more impressions → more clicks → more mortgage applications. No budget increase required.

Industry Perspective
What Agency Leaders Are Saying
"If you can show us where the inefficiency is before we commit budget, that changes everything. We need to defend performance to clients with evidence, not theories."
EVP, Investment
Global Holding Company
"Our allowlists are a black box. We inherit them, add to them, but nobody's audited the supply chain underneath. Finding inefficiencies we didn't know existed would be huge for clients."
Managing Director
Agency Trading Desk
"DSPs optimize bids, not paths. We've been asking for supply chain visibility for years. An independent layer that maps everything, that's what's been missing."
