Software development partner for US and UK businesses
Maxenius builds products, internal tools, integrations and AI automation for founders and growing businesses. An experienced team works to a focused scope, talks with you directly and uses AI tools for routine work, so you can get moving without recruiting first. We can take on the whole build or work alongside the developers you already have.
No technical specification needed. We aim to reply within one business day.
Recent work: GovBuddy’s three-brand order and CRM portal, and the options-analysis tool we built for OptionsGeek, covered by US Patent #11,004,151.
Maxenius combines two ideas: the ambition of ancient Rome and the words Maximum Genius.
Some of the companies we’ve worked with
Where we help
You don’t need to know which service you need. Pick the situation closest to yours, and each one links to the service that covers it in more detail.
01 · Launching a product
You have an idea, a customer need or a date to hit. We help you decide the smallest release worth launching, then design, build and launch it on web or mobile, so you learn from real users before paying for features they may not want.
02 · Adding development capacity
Recruiting takes time you may not have. A dedicated developer or small team joins your existing team, works in your tools and follows your priorities, so your own people stay focused on the work only they can do and keep ownership of the product.
03 · Replacing manual work
Orders, invoices, reports or customer requests are being re-entered by hand. We build the internal tools, portals and integrations that connect those systems, and add AI agents where they suit the task, so information is entered once and reaches the people who need it. The GovBuddy portal below is one example.
04 · Improving an existing system
The build may have stalled, the original developers may have moved on to other work, or a prototype now has to hold up for paying customers. We usually start by reviewing the code and infrastructure, then recommend what to fix, extend or rebuild, so you can decide with a clear view of the effort involved.
We also build mobile apps, AI features, websites and online stores. See all services
Relevant work
Each example covers the client’s problem and what we built. Where a client hasn’t shared business figures, we describe what the software does rather than estimate results.

Why Maxenius
Bringing in an outside team means trusting people you haven’t worked with yet on software your business will depend on. These are the questions worth asking, and how we set up the work to answer them.
“Who will I actually talk to?”
You talk with the engineers and designers working on your project, not only an account manager. Questions go to someone who knows the code, and if you have your own developers, ours work with them in the same channels.
“Will the budget hold?”
For defined projects we agree a written scope, timeline and price before the main work starts, and price any change before we build it, so you decide whether it’s worth doing.
“Will I know where things stand?”
On projects you review and approve the work at each milestone. Dedicated developers work in your tools, so progress shows up where your team already looks.
“Will we be tied to you?”
You own the code, designs and IP we create for you, as set out in your contract. We document the work so your own team or another vendor can carry it on.
“What happens after launch?”
You can keep us on for fixes and improvements, through a monthly allocation or follow-on projects, or take the product in-house with our documentation and handover. Support terms are agreed per engagement.
Building an in-house team means recruiting, onboarding and paying salaries before the first release exists. With us, an experienced team starts on the work itself, and you pay for a defined project or for the dedicated people you need. If you already have developers, we add capacity alongside them rather than replacing anyone.
Four working habits keep the time and cost down. We agree a focused scope, so the budget goes into what the first release has to do and the rest waits until users show it’s needed. Experienced engineers run your project, so decisions about data, architecture and integrations get made early, when they are cheapest to change. You talk directly with the people doing the work, so questions don’t wait on a go-between. And our engineers use AI tools for routine work such as setup, boilerplate and first-draft tests, then review that work before it ships.
None of this makes every project quick or inexpensive. It means your budget goes into the work itself, and on defined projects any change to the scope is priced before we build it.
Discuss your projectWays to work together
You don’t need to choose before we talk. Describe the work and how it tends to arrive, and we’ll suggest the smallest arrangement that does the job. Prices depend on scope and team size, so we confirm them before work starts rather than publishing a rate card.
Want to see how we work first? You can start with a one-week trial on real work, on terms agreed before it begins, so you can judge the people and the process before committing to more.
Ask about a trialHow it works
Each stage ends with something you can review, so you know where the work stands before deciding on the next step.
You tell us what you want to build or fix, in plain terms. We ask about your customers, timing, budget and the systems you already use, and tell you whether we think we’re the right fit.

About the name
Maxenius isn't a dictionary word, and that's intentional. Part of the name looks back to ancient Rome, an age when ambitious builders imagined cities at a scale the world had never seen. The other part is much simpler: Maximum. Genius. Maximum ambition, maximum thinking, maximum possibility.
Today the biggest things are often built from code rather than concrete. That's what we build: web, mobile, AI, cloud and automation software for businesses that want to build something bigger.
FAQ
It depends on what you need built and how you want to work, so we price once we understand the work rather than publishing a rate card. For a defined project we agree a written scope, timeline and price before the main work starts, and we price any change before building it. Dedicated developers work at a monthly rate that we confirm before they start. Compared with hiring, you avoid the time and cost of recruiting, but we won’t promise a fixed saving, because that depends on your situation.
That depends on what the first release has to do, so we don’t quote a standard timeline before we understand the scope. A focused internal tool and a multi-brand order system are very different jobs. After the first conversation we’ll tell you what a realistic first release looks like, and for a defined project the timeline is written into the scope before work starts. Keeping the first release focused is the most reliable way we know to get something live sooner.
You talk with the engineers and designers working on your project, not only an account manager, by call, chat or email. We arrange working hours that overlap with your business day in the US or UK. You don’t need to be technical: we explain decisions in terms of cost, timing and what changes for your customers or staff. Dedicated developers join your own tools, such as Slack, standups and your project board.
Experienced engineers make the architecture and quality decisions, and they review every change before it ships, including routine work such as setup, boilerplate and first-draft tests that they produce with AI tools. On defined projects you also review and approve the work at each milestone, so you see the quality for yourself before the next stage starts.
Yes. With an existing product, we usually start by reviewing the code and infrastructure, then recommend what to fix, extend or rebuild. That includes prototypes built with AI app builders that now need to hold up for paying customers. If you already have developers, we work alongside them in your tools and to your conventions, taking on the work they don’t have time for.
You own the code, designs and IP we create for you, as set out in your contract, and we document the work so your team or another vendor can carry it on. We can sign an NDA before you share details.
You can keep us on for fixes and improvements, through a monthly allocation or follow-on projects, or take the product in-house with our documentation and handover. Support terms are agreed per engagement, so you know what’s covered before you need it.
Yes. You can start with a one-week trial on real work, on terms agreed before it begins, so you can judge the people and the process before committing to more. We’ll explain how the trial would work for your project in the first conversation.
No. A few sentences on what you want to build or fix is enough to start. If you have documents, designs or an existing product, we’ll ask for them once we understand the problem.
Discuss your project
A few sentences is enough. You don’t need a technical specification, and you don’t need to know which service you want.
