We build software like we're going to run it ourselves.
Founded by engineers who got tired of watching agencies ship and disappear, Dev Luma exists to be the technology partner businesses actually want to keep.
From a two-person team to a global delivery partner.
Dev Luma started with a simple frustration: too many software agencies optimize for the next contract instead of the client's next milestone. We set out to build differently — senior engineers only, transparent process, and a partnership model that rewards us for your long-term success, not billable hours.
Today we work with founders building their first product and enterprises modernizing systems that run their business — across the UK, US, EU, Canada, Australia, South Africa, and the Middle East.

Years in business
The principles behind every engagement.
Ownership over output
We measure success by outcomes for your business, not lines of code shipped or hours billed.
Radical transparency
Weekly demos, shared roadmaps, and honest timelines — even when the news isn't what you want to hear.
Engineering craft
We build software the way we'd want to inherit it: documented, tested, and built to be extended.
Long-term thinking
We optimize for a five-year relationship, not a single invoice.
Nearly a decade of building.

A global team serving founders and enterprises across seven regions.
The founders.
Dev Luma was founded by an engineer and an operator, and both are still involved in the work day to day.
Krystal Tamayo
CEO & Co-Founder
Evergreen, Colorado, USA
Krystal co-founded Dev Luma and leads the company as CEO from Evergreen, Colorado. She runs the commercial side of the business: client relationships, how engagements are structured, and the company's growth across its US and international markets.
She is usually the first person a prospective client speaks to, and the one who decides — with the engineering team — whether Dev Luma is genuinely the right fit for a piece of work.
Arslan Matloob
Founder & CTO
Remote
Arslan founded Dev Luma and leads its engineering. He owns technical strategy across the company's work — architecture decisions, the standards delivery teams build to, and the technical side of every co-founder partnership.
He works closest to the AI and platform engineering practice, and is typically the person clients talk to when the hardest question on a project is a technical one.
A senior team, disciplines that cover the full build.
Every engagement is staffed by senior practitioners across these disciplines — not a rotating cast of juniors.
