Your existing customers are your biggest untapped revenue channel
We build AI-driven customer engagement infrastructure for consumer businesses - so you can drive revenue from the base you already have, without agencies or additional headcount.
The problem
Most consumer businesses are leaking revenue from their own customer base.
Your open rates are under 30%, meaning 7 in 10 of your customers never even see what you're sending them
You're over-investing in acquisition and underinvesting in the customers you already paid for
Your CRM is full of warm contacts going cold with no repeatable engagement strategy
Generic agency campaigns and batch-and-blast emails aren't moving the needle
There's a better way.

About
Built by an operator, not an agency.
Stackd was built by Ludo Martin - a growth operator with 10 years experience scaling consumer businesses including Deliveroo, Gorillas and launching an incubator backed delivery business in London, where he drove 600%+ revenue growth and built the commercial infrastructure from scratch across UK and US markets.
The customer engagement framework behind Stackd was developed and proven across real consumer businesses - not in theory, but under commercial pressure with real P&Ls and real retention problems to solve.
This isn't an agency. This is a defined process proven to work at some of the biggest consumer businesses in Europe.
Who it's for
Consumer businesses with a retention problem.
We work with consumer businesses that have an existing customer base and a retention problem. If you're running a consumer business and you know your customers aren't coming back as often as they should - this was built for you.
