Two ways to work with Lezo
Need better tools for your operations, or want to modernise an existing mobile app? Each offer has its own process and deliverables.
Business applications
Less re-entry, better tracking of your operations.
Case tracking, field data collection, reports, client portals: Lezo builds your business software, connects it to your tools and keeps improving it with you.
- Scoping with your users
- A first version focused on one use case
- Maintenance and new features after delivery
- About five times cheaper than classic development
For managers and operations leads of specialised service companies.
Expo migration
Builds and releases that are easier to manage.
Lezo analyses your React Native app, migrates it to Expo, checks the builds and hands over to your team.
- Assessment of the existing app
- Migration plan and validation
- Documentation and handover
- Maintenance about four times cheaper
For CTOs, engineering managers and mobile leads.
02AI-assisted development
The same software, for about a fifth of the cost
Business software used to cost around €100,000 to build, then €20,000 to €30,000 a year to maintain and improve. Lezo brings AI into every step of development, under the control of an experienced developer: the quality stays the same, the cost drops by about five.
- Build
- Classic development: €100,000With Lezo: €20,000
- Maintenance and improvements, per year
- Classic development: €25,000With Lezo: €5,000
Indicative orders of magnitude: the actual estimate depends on your scope.
How we use AI
- 01
AI writes, a developer decides
Architecture, technical choices and the approval of every change stay in the hands of an experienced developer.
- 02
Every change is checked
Code review, automated tests and regular demos: AI speeds up delivery, with no shortcuts on quality.
- 03
Standard code that you own
Widely used technologies, readable and documented code: another team can take it over at any time.
Your own software rather than a subscription?
At this price, having a tool built around your process costs, over a few years, about the same as a SaaS subscription designed for everyone. With one difference: the tool is made for you, and you own it.

FAQ
Before you get in touch
How much does a project cost?
The budget depends on what already exists, the use cases and the chosen scope. As a rough guide, business software that would have cost around €100,000 is now built for about €20,000, thanks to AI-assisted development. After a first conversation, the proposal states what will be delivered, the schedule and the support terms. You can contact us without a set budget.
Do we need a full specification to start?
No. Describe how you work today or what is blocking you. Scoping is precisely where we define a limited first version and its success criteria.
Doesn’t AI lower the quality?
Not when it is supervised. AI writes part of the code, but an experienced developer sets the architecture, reviews every change and validates it with tests. You receive standard, documented code that another team can take over.
What happens after delivery?
Depending on your choice, Lezo handles hosting, maintenance and improvements, or your team takes over using the documentation we deliver. Each part is priced separately.
Do we need a technical team on our side?
Not for a business application: a contact person who knows the process and can involve the users is enough. For an Expo migration, a technical contact takes part in the assessment and the handover.
What problem do you want to solve?
Describe your application or how your team works today. We’ll get back to you to talk it through.
