What Mantisy is built for.
We enjoy the projects with a lot going on: several kinds of users, daily operations that can’t stop, and data everyone needs to trust. That’s where we do our best work.
Retail & commerce platforms
Online stores and marketplaces where shoppers, merchants, store staff and riders each have their own app, all on one catalogue, with payments, stock and delivery connected.
Workflow systems that grow with you
Documents, approvals, permissions and audit trails set up for a team of ten or a head office. Start with what you need and add more as you grow. Our largest workflow system is used by 1,500 staff.
A lot of what we build stays behind closed doors, so we can’t show it here. Sit down with us and we’ll walk you through the projects closest to what you need.

Marketplace platformAEON Online — one storefront for every merchant.
AEON ran its own branches on a single-tenant system. We're opening it into a marketplace: one catalogue that carries outside merchants alongside AEON's own stores, across four connected apps. Two are live; the other two are still being built.

Complex platforms go wrong at the hand-offs. The people who design yours are the people who build it and keep it running.
Already built. Adjusted to you.
Custom engineering is our core. These are products we’ve already built and tested, so your project starts further along. We change it to fit how you work, put your brand on it and set it up with your team. It’s quicker than starting from zero.
Start from scratch, or from something that already works.
Whether you’re a team of five or a national chain, you probably don’t need everything built new. We’ll look at what you need first, then take the quickest honest route. Often it’s a bit of each.
If the way you work is what sets you apart, we’ll build around it.
We start with how your team actually works, then design and build the app or system to fit it. Nothing forced from a template.
If something close already exists, we won’t start from zero.
We take one of our own products and change it to fit your process and your brand. You get something working sooner.
If you already have systems that work, we’ll work with them.
We connect to what you run today, add the pieces that are missing, and bring in AI where it genuinely helps.
Four things decide how we work.
Based in Russey Keo, Phnom Penh. We work the way a small team has to — honestly, in person where it helps, and with one person you can always call.
Four ideas, one symbol.
Each part of the Mantisy mark stands for something clients ask of us. This is what each one means.
Come and tell us what you need.
Big job or small, a person here reads it and replies within two working days. Prefer to talk it through? Our door in Russey Keo is open, and we speak Khmer and English.
We only use your details to reply to this enquiry. We don’t share them or add you to a mailing list.
