Built to Level the
Technology Playing Field
SeynoGroup was founded on a simple belief: small and mid-size businesses deserve the same quality of IT as the largest enterprises in the world. For 15+ years, that belief has driven everything we do.
A Technology Partner,
Not Just a Vendor
SeynoGroup was founded in 2009 by Marcus Seyno after watching too many small businesses struggle with reactive, break-fix IT that cost more in downtime than it saved in fees. He set out to build something different — a firm that thinks like a business partner, not a repair shop.
Today, we're a team of 40+ engineers, strategists, and security specialists serving over 200 SMBs across the United States. Our clients span healthcare, financial services, legal, and technology — industries where IT isn't optional, it's existential.
We stay small on purpose. Every client gets a dedicated account manager, a named engineer, and direct access to senior leadership. That's not a sales pitch — it's how we've maintained a 97% client retention rate for over a decade.
The Principles Behind
Every Engagement
Precision Over Volume
We take on fewer clients so we can go deeper on each one. You get a partner who knows your environment, your goals, and your team — not a ticket number.
Radical Transparency
No jargon, no hidden fees, no surprises. We communicate clearly about what we're doing, why we're doing it, and what it costs.
Long-Term Thinking
We build relationships, not transactions. Our goal is to be your technology partner for the next decade — not just the next contract cycle.
Accountability at Every Level
We own our outcomes. If something goes wrong, we fix it — fast, without excuses. Our SLAs aren't aspirational; they're contractual commitments.
The People Behind the Work
Senior engineers and strategists who've spent careers solving the exact problems your business faces.
