Marsler is a small crew of engineers, designers and operators who ship apps, web platforms, commerce systems and AI agents for companies building things that don't exist yet — on this planet, and the next.
We turn fuzzy briefs into things that actually ship. For some clients that's a first app. For others it's quietly rebuilding the system their whole business runs on. No retainers, no theatre — we launch, then we teach your team to fly it.

A multi-brand home for the best aftermarket Tesla accessories — one curated storefront housing a collection of brands, shipping across three markets. We design, build and run it end to end: merchandising, checkout, post-purchase and the logistics behind every awkward, oversized box.

Hopeet is a Taiwanese valve manufacturer — a proud traditional-industry maker with little appetite for software. We gave them a quiet superpower: a serial-number lookup that turns a code stamped on a valve into a full PDF test report, generated and delivered to the customer in seconds. Heavy industry, finally online.

A secondary 16-inch screen that mounts below the Tesla OEM display and unlocks what the car already knows. Linken reads CANbus and third-party APIs for smart trip logging, live signal decodes and speed-camera alerts — and surfaces local third-party charging networks Tesla never shows you.
Read the full missioniOS, Android and web — from a first MVP to the platform your business runs on. Built to be handed back to your team, documented and unhaunted.
A senior set of eyes before you commit. We map the system, choose the stack, de-risk the roadmap and tell you the truth your CFO is going to ask about.
Storefronts, multi-brand commerce, point-of-sale and the fulfilment plumbing behind them. The kind of system that pays for itself in a quarter.
Support, sales and back-office agents wired into your real tools — with guardrails, a human escalation path and a tone that sounds like you, not a robot.
· lit. “a person from Mars”
A builder who works a little far from home. Patient, curious, slightly allergic to the way things have always been done. We took the name because the best work usually comes from people willing to think one planet over.
We started as operators tired of how slow it was to launch anything serious, so we rebuilt the stack we wished we'd had — then started flying missions for other people too.
We work in small, senior teams. No account managers, no offshoring, no innovation theatre. Every project has a founder on it, and we'd rather ship a rough first version in weeks than a perfect deck in months.
We run our own products and P&L — we know the questions your finance team will ask.
If the first version takes more than six weeks, we're building the wrong version.
We hand back something your team can run without us. That's the whole point.
