TheDiogen

Ad spend reconciliation for agencies

Every platform tells you a number.
We find the honest one.

TheDiogen connects to your clients' Google and Meta ad accounts, checks what was actually spent against what you budgeted and billed, and shows you exactly where the story stops matching up — automatically, every month.

Budget $12,000.00
Meta reported $11,410.32
You invoiced $12,000.00 off by $589.68

The problem

Three numbers, three sources

Budget, platform-reported spend, and what you invoiced rarely agree the first time anyone looks closely.

Found by hand, if at all

Most agencies still catch this in a spreadsheet, once a month, if there's time — and there often isn't.

Trust is the real cost

A wrong line on an invoice costs a client's confidence before it costs anyone money — even once it's explained.

How it works

  1. 1

    Connect

    Link your clients' Google Ads and Meta Ads accounts once. Nothing changes on their end.

  2. 2

    We watch

    Every day, TheDiogen pulls actual spend and checks it against budget and billing model.

  3. 3

    You get the number

    One view per client: what's owed, what's off, and why — before your client asks.

Why TheDiogen

Built for the segment nobody else prices for

Enterprise media-buying platforms are built for agencies twenty times your size, priced accordingly. Generic reporting tools show you dashboards, not invoices. TheDiogen sits exactly where you actually are: an agency with real clients, real budgets, and no time to reconcile them by hand every month.

Beta participants lock in 50% off for the first 3 months after public launch.

About

TheDiogen is an independent software company built specifically for advertising agencies, grounded in direct, hands-on experience inside the industry. The name comes from Diogenes, the philosopher who famously carried a lamp in daylight, searching for an honest man. TheDiogen does something similar with your ad spend — it searches through three numbers that rarely agree, and tells you which one is telling the truth.

We're currently in private beta, working closely with a small number of agencies to get the product right before opening it up more broadly.
