Hello world!

Hi folks, this is Dilla, co-founder & CPO of SPUN.

Welcome to The SPUN Stack.

We’re building SPUN to modernize how people discover, apply for, and manage visas, starting in Indonesia with global ambition. Behind that mission is a small but deeply thoughtful team of engineers, designers, operators, and problem-solvers who spend their days untangling complex regulations, structuring messy data, and turning bureaucracy into software.

This blog is where we’ll share more of that work.

You’ll hear directly from the people building SPUN, what they are shipping, how they think, the trade-offs they make, and the lessons they learn along the way. We will break down product decisions, architecture choices, experiments, internal tools, and the systems we are designing to make cross-border mobility simpler and more reliable.

Our hope is that by sharing openly, both the wins and the mistakes, our learnings can be useful for other builders working on complex, real-world problems.

If you are curious about how mobility infrastructure gets built from scratch, you are in the right place.

Let’s build.
