The intelligence layer for paid media.

Built and run by the Athens performance agency that uses it daily.

14 clients, live daily on real accounts.

The Problem

Agency growth is bottlenecked by senior judgment.

01

Every small agency runs on 1–2 senior people doing the morning account review across every client.

02

2–3 hours, every day, before any execution begins.

03

You can't hire senior media buyers fast enough to scale client load.

Why Now

Why now

01

LLMs crossed the threshold for reasoning over structured ad-account data in late 2024.

02

Generalist digital agencies are running on 10–15% margins. Only 10% of agency owners called 2024 healthy.¹

03

Senior media buyers cost €40–90K across Europe. You can't hire that judgment fast enough.

04

Every other software category got its AI-native challenger. Performance marketing has none.

The window is open for 18–24 months.

The Big-If

The big if

Every category of business software went through three stages: record what happened → orchestrate workflow → reason and act.

Code got Cursor. Legal got Harvey. Performance marketing got nothing.

Stish is that moment for paid media.

Read every ad account. Reason across platforms. Execute with the agency's client context layered in.

If this works:

  • 90% of digital marketing agencies have fewer than 50 employees¹ — they stop being throttled by senior headcount.
  • A 5-person agency manages 50 clients instead of 15.
  • The labor cost of running an agency converges toward the cost of software.
  • The agency middle layer — strategists, analysts, account managers — becomes software.

We're the agency that needs this. That's why we're building it.
