When the current product is not enough
You may be here because...
A dashboard or workflow has grown feature by feature and users no longer know where to start.
You need senior product, design and engineering judgement without hiring a full in-house team first.
How Flat 18 helps
One route from uncertainty to a product you can move forward.
We work across the product decisions, interface and software delivery that need to join up for the next release to make sense.
01
Shape the product
Clarify the user journey, scope the release and decide what needs to be true before you build more.
02
Design the experience
Turn dense tasks, data and edge cases into calm interfaces that help people move with confidence.
03
Build for the next stage
Ship the frontend, backend, integrations and release foundations that a growing SaaS product needs.
Selected work
Product work built around real complexity.
These are not templates. Each project starts with the people, decisions and constraints that make the product difficult to get right.
Actionable analytics
SignalMap
Made privacy-limited browser data useful by turning it into clear reporting and practical next steps.
People operations
SMP
Joined attendance, documents and employee actions into a quieter workspace for small organisations.
Workflow software
Social Publisher
Turned scattered publishing checks into one product teams can operate with less manual rework.
Before we start
Useful questions, answered plainly.
If the work sounds familiar, send the current product or idea. We’ll help you find the next sensible move.
Can you work from an existing SaaS product?
Yes. We can assess what exists, find the highest-risk product and technical decisions, then improve the experience in sensible stages.
Do you handle both product design and engineering?
Yes. We can take responsibility for the user journey, interface, frontend, backend, integrations and release support.
What should we bring to the first conversation?
A product link or prototype, the audience you are trying to serve, and the part of the product that is hardest to move forward.
