What Our Clients Say
Founders and product teams describe what changed after working with Leeonex — in their words, not ours.
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.”

FAQ
Questions about this service.
Choosing chart types that match the question, building interactive filters and drill-downs, and shipping a consistent visual system that stays readable on desktop and tablet.
Yes. Embedded product charts are a common deliverable. Performance and empty states are treated as product UX, not BI afterthoughts.
By using honest scales, clear units, and chart types suited to the comparison. Decorative chart junk is avoided.
Yes. Survey and research results can be turned into scannable visual summaries for stakeholders.
Choices follow the product stack and interaction needs. The library is a means; clarity of the visual answer is the goal.
Interactive filters and guided drill-downs help. For audiences who will not explore, static narrative visuals may be better.
Empty and partial states are designed explicitly so missing data is not mistaken for zero.
