About BigIn
The team behind startups that reached $10M+ before seed
BigIn is a software development company in Ho Chi Minh City, Vietnam, with an office in Dallas, Texas. Since 2016 we have built custom SaaS, mobile apps and AI features for startups, including several in the US, Belgium and the UK that reached $10M+ valuations before their seed round.
Every project runs in Agile sprints, with AI at each stage and engineers making the calls.

Core values
The more trust and value we earn for our clients, the more success we get
We treat every project as one that could change the client's business, combining technical expertise with an understanding of your specific needs.
01
Proactive changes
We listen to feedback and act on new ideas, in our own workplace and in the work we deliver. However ambitious your idea, we hold the work to the standard you would set yourself.
02
Balance
We balance what clients need with what our people need to do good work. We stay close through regular, direct communication and grow alongside your business.
03
Long-term target
One successful project is where a long working relationship starts. With every product we raise the bar for ourselves and look for ways to add real value.
“We have small teams spending short time building small things, but integrating regularly to see the whole.”
We run projects in short Scrum sprints. Each sprint ends with working software you can review, and your feedback shapes the next one. Small teams own their part and integrate often, so the whole product stays visible as it grows.
Inside each sprint, AI does the groundwork: research synthesized in hours during planning, design options explored in parallel, tests generated from the spec, release checks written from the diff. Engineers review every draft and make every decision.

Why our customers and employees love working with BigIn
At BigIn we do not just code rigidly, we get to bring our own ideas. The coolest thing I have learned is how a product goes from an initial idea to worldwide service.
We’ve been working with BigIn for two years and they’ve turned our vision into reality. They are one of the reasons ARC has won awards for our technology and innovation.
