Choosing a software development partner in Singapore usually comes down to a trade-off between local presence and an offshore engineering bench. This guide covers firms that publish a Singapore office and offer custom software work or dedicated-team outsourcing, from global consultancies to regional software houses. We focused on web platforms, backend services and enterprise systems, and left out shops that only build mobile apps. Every write-up draws on the firm's own site, and claims about size, certifications or projects are attributed to the firm. Use the list to shortlist two or three, then request a paid discovery phase and references before signing a larger contract.

1. Thoughtworks

Thoughtworks is a global technology consultancy that lists a Singapore office, operated by Thoughtworks Pte. Ltd., on its own office-locations page. Its Singapore site describes software engineering services built around an agentic development platform it calls AI/works, aimed at helping client engineering teams modernise legacy systems and shorten delivery cycles. The examples it cites involve a commercial bank and a business management platform, so the work shown skews towards large, complex estates rather than small one-off builds. That makes it a fit when you want a consultancy to shape architecture and ways of working alongside coding. Before committing, ask who from the Singapore team would sit on your project and how knowledge is handed back to your in-house developers.

2. Adamo APAC

Adamo APAC describes itself on its site as the Singapore office of Adamo Software, pairing Singapore-based engagement leadership with senior engineering teams in Vietnam. It lists three service lines: software development, AI and data services, and a dedicated development team model. The software development page covers custom web applications, mobile apps, MVPs for startups, and system integration and API work, using stacks it names as React, Node.js, Python, .NET and Flutter. The firm says it was founded in 2018 and has delivered more than 300 projects, figures it publishes itself and which you should test against references. Industries it highlights include travel, healthcare, fintech, e-commerce and logistics. Ask which parts of a project would be managed locally and which offshore.

3. Saigon Technology

Saigon Technology is a Vietnam-headquartered software house whose contact page lists a Singapore office alongside offices in the United States and Australia. Its site describes custom software development, dedicated development teams, staff augmentation, and web, backend and enterprise software work, with fixed-price engagements also mentioned among its models. The company says it runs development centres in Vietnam and publishes engineer profiles, which lets a buyer see who might join a team before signing. It reports recognition as a top workplace in Southeast Asian technology for 2026, a claim from its own pages rather than something we have checked. Because most engineering is offshore, ask how time-zone overlap, security controls and code ownership are handled for Singapore clients.

4. Genic Solutions

Genic Solutions is a Singapore software company whose site gives its address within Ubi Techpark and describes a team of developers based there. Its custom software page says it builds bespoke web, mobile and enterprise applications for small firms and large organisations, and claims more than 150 projects across healthcare, logistics, retail and finance. The site also covers field service management software and a Singapore project office that handles requirements, integration and compliance planning before development begins. It references alignment with Singapore PDPA expectations, which is a self-description rather than an audit result. A locally based team can suit buyers who want face-to-face workshops and an on-shore contact, so ask who writes the code and what documentation and source handover you receive at launch.

5. Xantec

Xantec Solutions publishes a Singapore office on its contact page, alongside a second office in Johor Bahru, Malaysia. Its software pages list custom development for complex enterprise workflows, plus industry systems such as customer relationship tools, wholesale ordering, restaurant procurement and student management. It also offers API and system integration, naming connections to AutoCount, Xero and the WhatsApp Business API. The firm describes a Singapore-led project governance model paired with nearshore development, and it also sells web design, so the software team sits within a broader agency. That mix suits small and mid-sized companies that need back-office systems joined up rather than a large platform build. Ask which engineers do the integration work and how ongoing maintenance is handled after go-live.

6. Kaopiz

Kaopiz is a Japan- and Vietnam-based software company whose site lists a Singapore office in One Raffles Place Tower 2. Its English homepage describes web app development, mobile app development, cloud services as an AWS partner, AI development, blockchain development and IT staff augmentation, all framed around enterprise-grade delivery. The firm says it serves clients across Japan, Singapore, Hong Kong, Australia, the US and Europe, and its news feed shows posts dated September 2026, including a guide to time-and-materials contracts. Delivery is largely offshore, so the Singapore office is best treated as a business contact rather than the engineering team itself. Ask how requirements are translated across locations, who owns the source code, and whether you can interview the developers proposed for your project.

How to choose

Decide the engagement model first. A fixed scope suits a well-defined build, while a dedicated team or staff augmentation suits evolving products. Ask each firm to explain, in writing, how scope changes are priced and approved, who manages the developers day to day, and what happens if a team member leaves mid-project.
Find out where the engineers actually sit. Many firms with a Singapore office run most development in Vietnam, India or elsewhere. That can work well, but ask about time-zone overlap, who attends your meetings, which staff are on-shore, and whether you can interview the proposed developers before you sign.
Insist on clear ownership terms. Your contract should say that you own the source code, designs and data, with repositories you can access during the build rather than only at the end. Ask about documentation standards, handover support and escrow options so you are not locked into one vendor.
Check security and data handling against Singapore expectations. Ask how the firm applies PDPA obligations, where code and customer data are hosted, who has access, and whether certifications such as ISO 27001 are current. Treat any badge on a website as a claim to verify, and request the certificate or audit summary.
Test the firm with a small first step. A paid discovery workshop or short pilot reveals communication style, estimating discipline and code quality at low risk. Ask for references from projects of similar size and stack, and speak to one client directly before committing to a long contract or large budget.
