How it starts
Book a consultation with a rough brief. Leeonex clarifies goals, scope, and technical direction before development starts.

The problem

Good ideas fail when the product direction is unclear.

Many businesses start with a feature list, a design reference, or an AI idea — but without clear scope, user flow, backend planning, or launch priorities, the product becomes slow, confusing, or expensive to build.

  • Clarity before development starts

    Scope, user flow, and priorities decided up front — not discovered halfway through the build.

  • The right features in the first version

    A focused first release beats a long feature list that takes months to ship.

  • Design, backend, and workflows aligned

    Interface, data model, and integrations planned together so they do not fight each other later.

  • A partner who thinks beyond code

    Technical decisions that account for how your business actually needs to operate.

How to scope a SaaS activation and retention dashboard when the numbers disagree

This educational concept turns competing product, billing, and spreadsheet numbers into one reviewable analytics scope: define activation and retention before drawing charts, join identities without inventing certainty, preserve cohort history, reconcile trusted examples, and show where the data is incomplete.

What Our Clients Say

Founders and product teams describe what changed after working with Leeonex — in their words, not ours.

Rated 5 out of 54.8 average15 client reviews
Marcus RendelFounder, Northbeam LogisticsRated 5 out of 5
Our dispatchers ran the whole depot off one shared spreadsheet that broke every Monday morning. Six weeks later they had a proper board. Nobody has opened that spreadsheet since.
Tobias LindqvistCTO, Verdal EnergyRated 5 out of 5
I have been burned by agencies before, so I kept the first contract deliberately small. We are three projects in now. The handover docs were good enough that my team took over without a call.
Daniel WeissOperations Director, Halden ManufacturingRated 5 out of 5
Eleven spreadsheets, gone. What sold me was that they spent two days on our factory floor before writing anything. The shift supervisors picked it up in an afternoon.
James OkoroEngineering Manager, Beacon FinancialRated 5 out of 5
I reviewed every pull request myself for the first month, expecting to find corners cut. I stopped after four weeks. My own team now writes tests the way theirs did.
Elena VasquezFounder, Terrace StudioRated 5 out of 5
I run a design studio and cannot read a line of code. They quoted in plain English and stuck to the number. That is the whole review, really.
Conor HylandGrowth Lead, Palladin SportsRated 5 out of 5
We were paying €6.40 a lead and the page was the bottleneck, not the ads. Same campaigns, new page, €2.90. I did not change a single keyword.
Owen MbekiHead of Demand Gen, Trestle SoftwareRated 4 out of 5
The first version underperformed our old page for about ten days. They rewrote the hero instead of arguing with me about it. It has beaten the old one every week since.
Greg TanakaVP Marketing, Ridgeway LegalRated 5 out of 5
Leads now reach our CRM and the duty solicitor's phone in the same minute. We used to find them in a shared inbox two days later. That gap was costing us real cases.

Priya RaghavanHead of Product, Cadence HealthRated 5 out of 5
I asked for a feature that would have taken three weeks. I got a call explaining why it was not worth building and what to do instead. That call saved us more than the retainer cost.
Amara OkonkwoMarketing Lead, FieldnoteRated 5 out of 5
Our old page converted at 1.2%. The rebuild sits at 3.4% on the same ad spend. I have stopped apologising for the link when I send it to press.
Sofia MarchettiCo-founder, Atlas RentalsRated 4 out of 5
We ran about a week late at the end. I heard about it the day it slipped, not the day it was due — which is more than I can say for the last two agencies we used.
Hana SatoProduct Owner, Mirai LearningRated 4 out of 5
Every Friday we got something we could actually click, not a status email. The time zone gap took a couple of weeks to settle, but after that I never had to chase anyone.
Rahul MehtaVP Engineering, QuantlyRated 5 out of 5
Eighteen months on, we are still adding to that codebase rather than working around it. Two engineers have joined since and neither needed hand-holding to ship.
Nadia BrekkeMarketing Director, Hallberg InteriorsRated 5 out of 5
Half our traffic is on phones and the old page took nine seconds to load on 4G. The new one is under two. Enquiries went up before we had touched the copy.
Isabelle FournierFounder, Maison ClairRated 5 out of 5
We had eleven days before the trade show. The page went live on day nine and we collected 340 emails at the stand. Nothing about it felt rushed.
