Our tools

An engine that keeps our team on top of the data.

We build our own optimisation engine because we do not want to depend on whatever the platforms choose to show us. It is a working tool, not a decision maker: the engine computes, a senior strategist decides, and puts their name to the outcome.

  • Google, Meta and TikTok data in one place, in real time
  • Predicted customer value, not just the click
  • Incremental profit as the goal, not the last click
  • Every change in the account is signed by a person

What we do

Three layers of growth. One team.

Performance advertising, premium websites and custom automation. We design and build them ourselves, and because one team holds all three, results add up instead of scattering across vendors.

How we work

From audit to growth in four steps

A transparent process with clear milestones and data at every step.

01

Audit & strategy

We analyse your data, competitors and potential. We set the goals and the plan.

02

Setup & build

We connect the AI engine, build the website or app, and prepare the campaigns.

03

Launch & learn

We launch, measure, and the AI learns from your data.

04

Scaling

What works, we multiply. Regular reporting and optimisation.

Why Roneby

People stand behind the performance, not a tool

Premium, provable, no hand-waving.

A senior team on the account

Your account is run by someone who knows the craft, not a junior with a template. Every decision has a name attached to it.

Tools we build ourselves

We develop the optimisation engine in house, so we know what it computes and why. It is a tool in a strategist’s hands, like Adobe or Excel.

Three layers under one roof

Ads, website and automation are designed and built by one team, so results compound and nobody points at the other vendor.

Numbers with a denominator

Every figure we show comes with its period, its source and the spend it came from. We do not use percentages without context.
