How we work
Software is easier to build when the right people are in the room
You should not have to explain your product through layers of salespeople and account managers. At Scalestack, you work with experienced engineers from the start.
We help businesses turn an idea into a working product, improve software that has become hard to live with, and add the right people to an existing team. We ask useful questions early, make the plan clear, and build with care.
Case studies
Complex work. Clear outcomes.
We work across new products, internal platforms, AI-assisted workflows and software that needs a second life. Every project starts with the same question: what would make this genuinely better for the people using it?
Gatehopper
As Gatehopper’s founding engineering team, we designed the platform to grow with the business: modular from the start, and running on infrastructure that expands with demand. Checkout stays fast through the busiest on-sales, every payment is split automatically between organizer, platform and tax, and each transaction is recorded in a ledger. New features build on that foundation rather than around it.

Project Gambit
A clearer way to work through complex business decisions. Research, financial analysis and risk assessment in one structured process, with the information behind every number easy to find and check.

Super.so
We work as an extension of Super’s engineering team from a different timezone, joining their daily standups and building to their conventions and standards. Together with their engineers, we’ve moved search from DynamoDB to Postgres and made it much faster, improved the stack so issues are quicker to trace, and helped move hosting off AWS onto Super’s own servers to cut costs.

Nexus
Our own AI intelligence hub, used every day.

Why Scalestack
A more straightforward kind of software partner
You need people who can understand a business problem, make sound technical decisions and communicate clearly while the work is happening. That is the job.
Talk to the people doing the work
You work directly with the engineers designing and building your software. Fewer handovers, clearer conversations, better decisions.
Know what you are getting into
For a defined project, we agree the scope, timeline and price upfront before development begins, so there are no surprises. If the scope changes, we offer flexible pricing to meet your needs.
Build faster, without cutting corners
We use AI tools where they genuinely help: to speed up research, reduce repetitive work and help engineers move faster. The important decisions, reviews and responsibility stay with experienced people.
Honest technical advice
We will not recommend a complicated solution because it sounds impressive. We recommend what we believe will work for the business, the users and the problem at hand.
A team that stays accountable
We take ownership of the work we agree to do. That means raising risks early, explaining choices clearly and finishing the job properly.
Built properly, not just quickly
Software has to work after the demo. We care about the parts users notice and the parts they do not: a clear experience, reliable behavior, maintainable code, sensible security decisions and a system that can change as the business changes.
Solutions and pricing
Choose the way of working that fits the job
Some work is best handled as a clearly scoped project, with the price agreed before development begins. Other work needs an ongoing team, monthly or by the hour. We will help you choose the straightforward option.

How we deliver
Clear from the first conversation
We keep the working relationship simple: you speak to the engineers doing the work, know what is happening and can make decisions with the right information in front of you.
Understand the work
We learn what you need to achieve, who it is for and what success looks like.
Make a plan
We define the work, the approach and, for scoped projects, the price before we begin.
Build in the open
You see progress regularly, speak to the people doing the work and can give feedback while it still matters.
Launch and improve
We test carefully, support the launch and keep improving where it makes sense.

What does Scalestack do?
We design, build and improve custom software: new products, AI features, and changes to systems a business already runs. Scalestack is a software engineering company in Ho Chi Minh City, Vietnam. Scoped projects, such as an MVP or an AI pilot, have their scope and price agreed before development begins. Ongoing work, extra engineers, consulting and maintenance run monthly or by the hour. There is more detail at scalestacktech.io/services.
See what we do →How do we get started?
Start with a conversation about what you are trying to achieve, what you have already tried and where you need help. If there is a fit, we will suggest a sensible next step. You can reach us at contact@scalestacktech.io.
Start a project →Will we work directly with the engineers?
Yes. You will be able to speak to the people designing and building the work. We keep communication direct so decisions do not get lost in handovers.
Meet the team →Do you offer fixed prices?
For scoped project work, yes: we agree the scope and price before development begins. If the work is ongoing or the priorities are expected to change, a dedicated team model is usually a better fit.
See packages and pricing →What happens if we need to change the scope?
Changes are normal. We discuss the impact on cost, timing and priorities before the work changes, so you can make an informed decision.
Do you only build AI products?
No. Scalestack is an engineering team. We build custom software, improve existing systems and add AI where it genuinely helps the people using the product or process.
See our work →What do you mean by AI-assisted development?
We use AI tools to help engineers work more efficiently on suitable tasks. Experienced engineers remain responsible for the design, code, review, testing and the final product.
Can you work with our existing team or software?
Yes. We can join an existing team, take on a defined project or help improve a system you already rely on. We start by understanding what is there and where we can add the most value.
See Maintenance and Support →How do you make sure the software is good quality?
Quality is built into the work: clear requirements, experienced engineering, regular review, appropriate testing and a careful launch. The exact approach depends on the product and the risk involved.
Who owns the code and the intellectual property?
You do. Every design, every repository, and every line of code we write for you is yours. Your product vision stays yours throughout. Our role is to turn it into working software and to raise the engineering questions worth asking along the way.
What technologies do you work with?
Broadly, and deliberately so. Our work spans web and mobile development, cloud and infrastructure, data engineering, and AI and machine learning, across the major languages and ecosystems in each. We are not tied to a single stack. If you already have a codebase, we work in what it uses rather than pushing you toward what we happen to prefer, and if you are starting from scratch, we pick the technology that fits the problem and the people who will maintain it. We are happy to talk specifics for your project.
Where is your team based?
Our team is based in Ho Chi Minh City, Vietnam. Our lead engineers were educated in Canada and Singapore, and we work with companies in North America and Europe every day, joining their standups and working to their standards from a different timezone.
