Twelve years. 320+ clients. Zero excuses.
Technology That Works.
Partners Who Stay.
Most technology vendors sell you a product and move on. SolidMark operates as a long-term technology partner — accountable for outcomes, not just deliverables. Here is what that looks like in practice.
Uptime Commitment
We put our SLA in writing and back it with financial penalties. Our 99.9% uptime guarantee applies to all managed infrastructure clients. In twelve years, our actual uptime across the client base has averaged 99.94%. We are not guessing — we are measuring.
Response Time Standard
Critical issues receive a response from a qualified engineer within 2 hours, any time of day or night. Not a callback. Not a ticket number. A human being who can solve the problem. We staff our support operations around that commitment.
Ownership, Not Excuses
When something goes wrong in your technology, we do not point fingers at vendors or blame configurations from before we arrived. We own the outcome. We fix the problem. We report on what happened and how we prevented it from happening again.
Six Services. All
Measured by Outcomes.
Every service SolidMark offers is connected to a measurable business outcome and backed by a contractual SLA. We do not deliver activity — we deliver results your business can count on.
Custom Software Development
Purpose-built web applications, mobile apps, APIs, and system integrations designed around your specific business logic. We start with deep discovery — not mockups — to understand what your business actually needs before writing a line of code. Full-stack development in React, Node.js, Python, and .NET. You own every line of code from day one.
Managed IT Services
Your complete IT department under a predictable monthly fee. Helpdesk support for your team, 24/7 endpoint and network monitoring, patch management, vendor management, and infrastructure support. 99.9% uptime SLA. Sub-2-hour response on critical issues. We become your IT department — or the one you always wished you had.
Cloud Infrastructure
Cloud migration strategy, architecture, implementation, and ongoing managed operations across AWS, Azure, and Google Cloud. We design for cost efficiency from day one (most clients save 25–40% on cloud spend within 90 days of our involvement), then manage the resulting environment with the same rigor as our on-premise managed clients.
Cybersecurity
24/7 SOC monitoring, vulnerability assessment, penetration testing, incident response, and compliance program management for HIPAA, SOC 2, PCI DSS, and CMMC. We have successfully contained 12 ransomware incidents without data loss. We have guided 40+ clients to HIPAA compliance and 25+ to SOC 2 Type II. Security that actually protects you.
Data & Analytics
Data warehouse design, ETL pipelines, and business intelligence dashboards that connect your business data into a single, accurate, real-time view. We build on Snowflake, dbt, and Tableau or Power BI. Average client outcome: leadership teams replace 8–12 hours of weekly manual reporting with one live dashboard that updates automatically.
IT Consulting & Strategy
Technology roadmap development, vendor selection, IT budget planning, and fractional CTO services for businesses that need senior technology leadership. Our fractional CTO engagements have helped 35+ Midwest businesses build their first technology strategy, navigate major system selections, and prepare for acquisition or investor diligence.
We Did Not
Open an Office Here.
We Built Our Home Here.
SolidMark was founded in St. Louis in 2012. Our team lives here, our clients are here, and our reputation is built on what we deliver to businesses in this community. That is a fundamentally different accountability model than a firm headquartered elsewhere that opened a Midwest outpost.
Twelve years in one market means we know the technology landscape of St. Louis in ways that national firms cannot match. We know which vendors deliver and which oversell. We know the specific regulatory environment that affects healthcare and financial services businesses in Missouri. We know the talent market. We know the risks.
That local knowledge, combined with enterprise-grade technical capabilities, is why 320+ St. Louis businesses trust SolidMark to manage their most critical technology infrastructure.
About SolidMark →What St. Louis Businesses
Say About SolidMark.
“We had six infrastructure outages in Q1 before bringing on SolidMark. In the 14 months since, we have had zero. Their proactive monitoring caught and resolved 23 issues before they became outages. The ROI on managed IT has been 4:1 in productivity alone, not counting the business we did not lose during downtime.”
“SolidMark built our patient scheduling and intake platform in 11 months — on time, on budget, and built exactly the way our clinical team needed it. Four months after launch, we are seeing 40% faster intake processing and 28% reduction in no-shows. No off-the-shelf product could have done what they built for us.”
“A competitor suffered a ransomware attack. Two weeks later, SolidMark had completed a full security assessment of our environment, identified 14 critical vulnerabilities, and had remediation in progress on all of them. In 90 days we went from significantly exposed to having a security posture I am comfortable defending to our regulators and board.”
“Our SolidMark fractional CTO built the three-year technology roadmap that our PE investors required for our growth plan. It passed their technical due diligence review without a single follow-up question. The same person who built the roadmap is now executing it with our team. That continuity has been invaluable.”
Twelve Years of
Industry-Specific
Technology Knowledge.
Twelve years in St. Louis means we have deep knowledge of the technology challenges specific to the industries that drive this region. We have built HIPAA-compliant healthcare systems, PCI-compliant financial platforms, and OT/IT-integrated manufacturing infrastructure — not as a side capability, but as a core part of what we do.
