Software your business runs on, built by people you talk to directly.
Maxenius builds websites, online stores, mobile apps, custom software and AI agents for founders and growing companies in the US and UK, then helps market them after launch. You work with the senior engineers and designers doing the work, you own everything they build, and you can judge us on a one-week trial before committing to more.
Some of the companies we’ve built for
What working with us looks like
An outside team that doesn’t need managing.
Outsourced projects usually go wrong in familiar ways: requests get relayed through people who don’t write code, nobody can say where things stand, and the finished system is hard for anyone else to maintain. We set every engagement up to avoid those problems from the first week.
Your questions go to the engineers and designers who have shipped production systems, not to an account manager who has to pass them on.
AI tools draft the scaffolding, boilerplate and first-pass tests. Our engineers make the architecture calls and review every change, which is where quality is decided.
Code, designs and IP belong to you, with documentation and a handover your own team or another vendor can pick up. You are never locked in.
Every engagement can begin with a one-week trial on real work, so you judge the people and the process before committing to anything longer.

ExploreFor complex and regulated systems
When the system handles money, patient data or audit obligations.
Some systems can’t be fixed after an audit finding. Our enterprise practice builds financial reconciliation platforms, a regulated UK pharmacy platform and other systems where every action needs a record and each user should only see the data they are entitled to. Audit trails and database-level access rules (row-level security) go in from the start, not as a later retrofit.

FAQ
What founders usually ask first
How do you move quickly without cutting corners?
Our engineers use AI tools for the repetitive parts of a build: scaffolding, boilerplate, first drafts of tests. Architecture, code review and quality decisions stay with senior people. The time saved comes from the routine work, not from skipping review.
What size of project do you take on?
Anything from a focused website or store build to a regulated enterprise platform. Most clients either scope a defined project or keep a dedicated person or team on a monthly basis. The same senior team works across both.
Can we start small to see if it’s a good fit?
Yes. Every engagement can begin with a one-week trial on real work, with the same people who would carry on afterwards. If it isn’t right, you stop there with no further obligation.
Do you work with US and UK companies?
Most of our clients are in the US and UK. Our working hours overlap with yours, and you communicate directly with the people doing the work, in clear English, by call, chat or email.
Who owns the code and the IP?
You do, on every type of engagement. All code, designs and assets belong to you, with documentation and a handover clear enough for your own team or another vendor to take over.
What happens after launch?
Many clients keep us on for fixes and new features, either through a dedicated monthly allocation or smaller follow-on projects. If you would rather take the product in-house, the documentation and handover are set up for exactly that.
Talk through what you need with someone technical.
