It was 1998, and Dave Monk had seen enough. Too many business owners held back by tech they didn't understand, drowning in problems instead of growing their business.
So he started ArcSource on a simple idea: technology should be a tool for progress, not a source of frustration — and the businesses using it deserve a partner, not just a vendor.
By 2002, the first hires had joined, all sharing Dave's belief that IT is a people business first.
That's still the heartbeat of ArcSource today: relationships and trust, powered by technology that protects and empowers the businesses we serve.





Behind every business is a team of people trying to grow something they care about. Four things guide how we show up for our clients every day:
Technology serves people, not the other way around. Every decision we make starts with how it impacts the humans behind the screens.
We do what we say we'll do, every time, even when it's inconvenient. Trust is earned in the small moments, not just the big wins.
We're genuinely excited about the tools that move your business forward, and we love sharing that excitement with our clients.
We never stop raising the bar, for ourselves and for our clients. What worked yesterday is not good enough for tomorrow.
We serve growing Bay Area businesses who need smart, reliable IT that keeps up with their pace and ambition.

"Fantastic! Everyone at ArcSource is very professional and takes a great deal of interest in making our computer system work properly. "

"ArcSource is knowledgeable, personable, forward thinking, thorough, and accommodating. Because of their vast IT knowledge, ArcSource implements the best fit for your IT needs. When I'm sleeping, ArcSource is monitoring my network. "

"We’ve had some ‘lone wolf’ IT people...you wouldn’t even be able to reach them because they were so busy on other projects and you might have to go a week trying to troubleshoot something yourself. That was very frustrating. But ArcSource has the bandwidth to handle stuff and if the crisis arises they can put the bodies on it to solve it. I think that’s a plus. "

"Our previous IT provider was a guy who came when it was his schedule, at his own time frame. He had no respect for our needs or any emergencies we had… always came in after hours and just never responded. It was night and day when we switched over to ArcSource. I think you guys are a very talented team. And I would say, in the IT world, often overlooked but highly essential. We always come to you when we are in a panic or in a need and you guys have always been there for us."

"Since we went on ArcSource Managed Care, we’ve been able to transition away from putting out fires and are now looking ahead, getting out in advance of things becoming obsolete. We’re happy with the minimal amount of downtime that we used to suffer from."

“ArcSource is solid and dependable. They have been around for a long time and having that consistency and knowing they will be around in the future is reassuring for an IT support company. ArcSource has a structured and disciplined approach to setting up the network and systems. They are a good resource when considering new technology investments.”
