Your business has outgrown WhatsApp and Excel.

Orders arrive on WhatsApp. Stock lives in a spreadsheet. Approvals sit in someone's inbox. Custom software puts it in one place, shaped around the way your team already works.

Software that fits your business, not the other way round.

Not sure which fits? Ask us

Websites and web apps

Fast websites, e-commerce, customer portals and booking systems that work in any browser, on any device.

Internal tools

MVP / PoC as a Service

A first working version with only the core features, tested with real users before you invest more. A focused MVP typically takes 8 to 12 weeks.

Have something like this in mind? Tell us what you need

Four steps. No surprises.

  1. 01Discover

    We map the work and agree the scope, then you get a plan.

  2. 02Design

    A clickable prototype before any code, so you see how it works first.

  3. 03Build

    Working software every two weeks, so you can try it as it grows.

  4. 04Run

    Launch, monitor and keep improving.

Work with us the way that fits.

Project
Fixed scope, fixed timeline. For a defined product or system.
Dedicated team
Your own engineers in Da Nang, managed from Singapore. For ongoing engineering work.
Forward deployed
Senior engineers inside your team until it's live. For problems still being worked out.

Before you ask.

Anything else, ask me directly at dan@heysheep.sg or on WhatsApp at .

How much does it cost?

Every project is quoted on its scope, after a short call. Tell us what you need and HeySheep's team will quote it.

How long does it take?

It depends on the scope. A focused first version (MVP) typically takes 8 to 12 weeks; larger platforms are delivered in phases. You see working software every two weeks while it's built.

Who will I be talking to?

Me, Dan. I work with HeySheep Technologies, a Singapore software company founded in 2020, and I'll stay your contact through the project.

Where is the team?

HeySheep's headquarters is in Singapore, and its own R&D centre is in Da Nang, one hour behind Singapore, so both teams work the same business day.

I only have an idea. Is that enough?

Yes. A sentence or a sketch is enough to start. We begin with Discover and a clickable prototype, before any code.

If your team does it by hand, it can probably be built.

A sentence is enough to start. I reply within one working day.
