Billy Dunn

Founder. Designs the systems, supervises the work, and looks for ways to improve the business.

Billy at work, from the rack to the bigger picture.

It started with computers at seven.

People started asking Billy for help, and they never really stopped. What began as a childhood interest became BDunn & Company in 1989.

That same curiosity still drives the work: understand how something works, find a better way to do it, and make it useful to someone else.

From individual computers to entire businesses.

Over the years, the work grew to include networks, servers and the systems businesses depend on. For about a decade, Billy single-handedly ran the entire data center for one large client, a nationwide company doing about $8 billion a year. When he left, they hired a team of eight to replace him.

Experience shaped the approach we use today. Choose proven technology, configure it carefully, document it thoroughly and keep improving it.

AI is not new here.

Billy has studied AI research and experimented on his own since the 1980s. Today that helps clients connect information across their systems, investigate difficult questions and build tools that change how work gets done.

He starts by showing what is possible, learns which problems matter most to the business, then usually builds or implements the improvement with the team.

Billy, on certifications

I've collected plenty: CISSP, CISM, CCNA and the full Microsoft engineer track, back to MCSE. At one point I was hunting for one with a Q or a Z in it, just to finish the alphabet.

I keep the ones that matter for your systems current. No client has ever asked to see one, and that's fine.

Judge us on whether your systems work and whether we answer the phone.

The clients we have come first.

We take on new clients a few at a time, so the ones we already have stay in good shape. A lot of IT companies grow by stretching the same people over more and more clients. We don’t trade our clients’ service for faster money.

When we’re busy, we pause new clients. The line next to the Book button says whether we’re taking them right now. Either way, Billy still answers questions.

We’re based in Arlington, with clients across Texas and internationally. We typically work with businesses of up to 150 people.

We work best with people who value straight advice, treat people well, and want us involved in their success. There is no contract keeping them here.

We resell nothing and receive no vendor commissions.

How we charge

Billy reads these himself. You’re welcome to ask while you’re still exploring, including before involving the owner.
