Software that makes the hard parts disappear.
Lessier builds custom software and fixes the systems that aren't working anymore. Less manual work. Fewer workarounds. Tools that fit how your team actually operates.
Start today. You can have working custom software by March 1st.
For teams running on spreadsheets, inbox threads, and "did anyone do this yet?" checks.
You already know what's broken.
Your team works around it every day — the manual steps, the tools that almost fit, the things everyone knows need fixing but nobody has time to touch.
“You don't need more tools. You need less in the way.”
5 people, 1 spreadsheet
Everyone edits. Nobody trusts it.
Too fragile to touch
It works — until someone changes anything.
Off-the-shelf, off-target
Almost fits. Never quite right.
What we build
Modernization
Old systems slow everything down. We refactor, untangle, and upgrade the foundation so your team can move again. No big-bang rewrites unless that's truly the right call.
Custom applications
Internal tools, portals, dashboards, mobile apps. Designed for how your team works, built clean enough for your team to maintain after handoff.
Integrations and automation
Your tools should talk to each other without a person in the middle. We connect systems, automate the repetitive stuff, and make sure data lands where it needs to.
AI where it earns its keep
Search, summarization, routing, assistive features. We add AI when it genuinely reduces work, and we test it like engineers, not enthusiasts.
How a project works
Map the real workflow
Not the ideal one. The actual one, with all its edge cases and "oh, and also" moments. We figure out what matters before we write any code.
Design the smallest useful version
Something you can ship and benefit from quickly. Not a six-month plan with a demo at the end.
Build in short cycles
Weekly demos. Clear progress. You always know what's done and what's next. No surprises at the finish line.
Ship, measure, improve
Launch is the starting line. We instrument, monitor, and keep refining so the system gets better with use.
Selected work
Operations dashboard
A team was checking four different systems every morning to figure out what needed attention. We built a single dashboard with role-based views and an alert pipeline. Morning checks went from 45 minutes to five.
Legacy system migration
Core product was stuck on a stack nobody wanted to touch. We migrated it incrementally — feature by feature, with parity checks at every step. Release velocity tripled. Production incidents dropped.
Intake and routing automation
Requests came in by email, got triaged in a spreadsheet, and were assigned over chat. We replaced the whole chain: structured intake, automatic validation, smart routing, and status notifications. The team got hours back every week.
