About eXcelisys

Custom Software Development, Built by People Who’ve Actually Done the Work

Since 2001, eXcelisys has partnered with more than 2,000 businesses, organizations, and institutions worldwide to design, build, fix, and support custom database and web applications. We’re a 100% USA-based team specializing in FileMaker, WordPress, Airtable, and custom web application development — and we’ve built our reputation on getting complex projects right, not just fast.

Whatever the size of your project, company, or budget, our goal is the same: your complete satisfaction, delivered by a team that treats your business like it’s our own.

Who We Are

A Tight-Knit Team, Not a Call Center

eXcelisys isn’t a call center that routes you to whoever’s free. We’re a tight-knit team of solutions consultants, project managers, and developers — many of whom are partners and owners in the company — who bring decades of real-world, cross-industry experience to every engagement.

Christo, our founder and president, started the company after years of consulting, employee, and management roles across a range of computer platforms and database technologies. He built eXcelisys around a simple emphasis: customer service and quality, first. That principle still shapes how the team operates today.

Around him, a team of dedicated FileMaker, WordPress, and full-stack web developers has grown — several with FileMaker development experience stretching back to the 1990s, and backgrounds spanning industries as varied as medical manufacturing, orthopedic and nonprofit care, publishing, aviation, and enterprise IT. Our solutions consultants and project managers act as your day-to-day advisors, translating your business needs into technical plans — and holding the line on honest counsel, even when it’s not what a client wants to hear, because we’d rather be direct than deliver sub-par results.

What We Do

Three Ways We Help

Whatever the challenge, it starts with one of these — and often ends up touching all three.

Our technology proficiencies include:

Chosen not because they’re trendy, but because they’re proven tools we know how to wield well.

How We Work

Every Engagement Follows the Same Core Process

Listen → Advise → Plan → Develop → Test → Deploy → Support

Throughout, communication happens via teleconference, on-site visits when needed, and a shared project management system — so nothing gets lost between our team and yours. And when the project wraps, you retain full rights and ownership of everything we build.
