Build & Software
Custom Software Development in Singapore
We build bespoke software for the problems off-the-shelf tools can't solve, from full SaaS products to system integrations and workflow automation. Senior engineers own the architecture, and we work AI-native so the software is genuinely smarter where it counts. One accountable partner takes you from concept to a running, maintained system.
💡 Custom work may be up to 50% EDG-supported, subject to Enterprise Singapore approval — check your eligibility.
For companies held back by manual processes, disconnected systems, or software that no longer fits how they work. Ideal if you have a SaaS idea to launch or an operation that needs its own engine.
Everything you get, handled by one team.
Bespoke business software
Systems designed around your exact process, replacing spreadsheets and workarounds.
SaaS & MVP development
Launch a market-ready product, from first release to multi-tenant, billing-ready platform.
Systems integration
Connect ERP, CRM, accounting and other tools so data moves without manual re-entry.
API design & development
Robust, documented APIs that let your systems and partners talk to each other securely.
RPA & workflow automation
Automate repetitive, rules-based tasks to cut cost, delay and human error.
AI-native features
Practical AI such as search, extraction and assistants built into the software where it adds real value.
Outcomes, not just deliverables.
- Reclaim hours lost to manual, repetitive work through targeted automation
- One connected system of record instead of data trapped in disconnected tools
- Software that fits your process exactly, giving you an edge competitors can't buy off the shelf
- A senior-led build you can maintain and extend, not a black box you're locked out of
The GDI Build Loop.
Discover
A free scoping call and short discovery to pin down the goal, the scope and how we'll measure success.
Prototype
We shape the solution and put a working prototype or clear plan in front of you — not a slide deck.
Build
Senior, AI-native engineers build fast, with working progress you review as we go.
Launch
We deploy, test and hand over — documented, secure, and fully owned by you.
Support
Ongoing support, iteration and optimisation as your needs grow.
Engagement & pricing
Fixed-scope projects or ongoing retainers — your choice. Retainers cover scheduled maintenance and changes, not round-the-clock monitoring. We give a clear fixed quote after a free scoping call, and you own everything we build. Eligible custom work may be up to 50% EDG-supported, subject to Enterprise Singapore approval. PSG funds only listed vendors' pre-approved products, and GDI is not listed.

Why choose custom software over an off-the-shelf product?
Off-the-shelf is faster and cheaper when it fits. Custom makes sense when the tool shapes your business rather than the other way around, when you need to connect systems that don't talk, or when the workflow is your competitive advantage. We tell you honestly which path fits.
Can GDI actually deliver complex software?
Yes, and we prove it with our own products. We built and operate PropAce, TenderSG and Destiny Compass, a live AI SaaS. The same senior engineering that runs those products builds your project.
How do you price a custom build?
We scope the work into phases and give a fixed quote after a free scoping call, so you can start with a focused first release and expand with confidence rather than sign a blank cheque.
Is custom software eligible for EDG?
Bespoke software that drives productivity or business transformation may qualify for the Enterprise Development Grant, subject to Enterprise Singapore's prevailing criteria and approval. We structure the engagement so it fits your intended funding route.
