Ann Arbor's PE Sponsor and Portfolio IT Partner
Supporting a lower-middle-market PE sponsor headquartered in Ann Arbor with active add-on diligence and portfolio-company operations. Managed IT, cybersecurity diligence and post-close MSP services for Washtenaw County and the greater Detroit metro.
Atticus Rowan is the managed IT and cybersecurity partner for a lower-middle-market PE sponsor headquartered in Ann Arbor. Our practice spans sponsor-side IT due diligence on add-on acquisitions, post-close carve-out execution and ongoing MSP operations for the sponsor's portfolio companies. That combination is an uncommon fit for a regional MSP and reflects the compliance-first, sponsor-ready posture we bring to every Ann Arbor engagement.
Why Ann Arbor-area employers choose us
Ann Arbor is a distinctive mid-market: a dense concentration of lower-middle-market private equity sponsors, a significant technology and biotech cluster anchored by the University of Michigan commercialization ecosystem, and manufacturing operators across Washtenaw County that face the same cyber insurance and customer-audit expectations as their Detroit-metro peers. The combination produces IT and cybersecurity needs that are both sponsor-side (diligence, 100-day planning, post-close standardization) and portfolio-side (operational MSP, audit readiness, incident preparedness).
Response time in Ann Arbor: Remote response within 15 minutes during business hours. On-site support in the Ann Arbor / Detroit metro coordinated through the sponsor engagement and regional support partners.
The Ann Arbor market
Ann Arbor is home to a lower-middle-market PE sponsor we support, the sponsor relationship spans diligence on add-on acquisitions, portfolio-company carve-out and ongoing MSP operations.
The University of Michigan ecosystem anchors a significant technology and biotech commercialization cluster where SOC 2 readiness and enterprise customer audits arrive earlier than most mid-market firms expect.
Washtenaw County manufacturing includes automotive Tier 2 and Tier 3 suppliers, precision manufacturers and specialty industrial producers facing OEM security cascade and cyber insurance pressure.
Ann Arbor sits approximately 40 miles west of Detroit and 45 miles south of Flint, within practical range of the broader Detroit-metro corporate and sponsor footprint.
Atticus Rowan operates as a remote-first MSP with on-site coverage coordinated through the sponsor engagement and regional support partners cultivated for the Detroit-metro geography.
How we work with Ann Arbor industries
Private-equity portfolio companies
We support a lower-middle-market PE sponsor based in Ann Arbor across the full engagement lifecycle: pre-close cybersecurity diligence on add-on acquisitions, post-close carve-out execution, 100-day cybersecurity standardization and ongoing MSP operations for portfolio companies. That engagement is our anchor in Ann Arbor. For sponsors, operating partners and portfolio company leadership, our experience is lived rather than theoretical, we know what a modern PE buyer examines, what a sponsor's operating-partner team reports on and what the 100-day plan actually delivers post-close.
Technology and SaaS
Ann Arbor's technology ecosystem, University of Michigan spinouts, commercialization-stage biotechs and product-led software companies, faces enterprise-customer security reviews and SOC 2 readiness expectations earlier in their growth arc than most mid-market operators. We build the control environment that satisfies enterprise customer audits, guide companies through SOC 2 Type I and Type II readiness and produce the evidence library that scales past the first hundred customers.
Manufacturing
Washtenaw County and the broader Detroit-metro manufacturing base, including Tier 2 and Tier 3 automotive suppliers, precision manufacturers and specialty industrial producers, face cyber insurance renewal and OEM security cascade expectations that have climbed every year. We separate production systems from corporate IT, monitor the boundary and document the control environment carriers and customers expect.
Professional services (legal, accounting)
Law firms, accounting practices and consulting firms serving the Ann Arbor PE and technology ecosystem hold sensitive client data under professional obligations where accidental disclosure is a malpractice or bar-grievance event. Our work emphasizes matter-level access segregation, phishing-resistant authentication and the documented evidence professional-liability carriers increasingly ask for at renewal.

Common questions, Ann Arbor
Do you work with Ann Arbor private-equity sponsors?
Yes. Our Ann Arbor practice is anchored by a lower-middle-market PE sponsor we support across diligence, carve-out and ongoing portfolio MSP work. We welcome conversations with similarly-profiled sponsors evaluating IT due diligence support, post-close cybersecurity standardization or ongoing portfolio-company MSP coverage.
What does sponsor-side IT due diligence actually cover?
Pre-close cybersecurity and IT assessment of a target company. Typical scope: framework-aligned control environment review (usually NIST CSF 2.0), cyber insurance posture review, incident history, vendor-risk inventory, backup and recovery tested-restore evidence, regulatory posture (HIPAA, NIST 800-171, SEC examination expectations where applicable) and a prioritized roadmap for any identified gaps. The deliverable is a diligence memo the sponsor's operating partner and investment committee can rely on to size post-close investment or flag material issues before close.
We're evaluating an add-on to an existing portfolio company. Can you scope diligence on a compressed timeline?
Yes. Add-on diligence often runs on shorter windows than platform diligence. We scope the work against the specific LOI timeline, prioritize the highest-impact questions first (tested backup, cyber insurance posture, incident history, regulatory exposure) and produce a tiered memo that distinguishes must-address findings from can-address-post-close findings. Our experience with a PE carve-out from a publicly-traded industrial-services parent operator directly informs how we structure these engagements.
How do you support Ann Arbor technology and biotech companies?
Technology and biotech companies typically hit enterprise customer security reviews and SOC 2 requirements earlier than general mid-market firms. We build the control environment, guide the firm through SOC 2 Type I and Type II readiness (we are not a SOC 2 audit firm ourselves; we are the MSP that makes the audit reach a clean opinion) and produce the evidence library that scales past the first hundred enterprise customers. For University of Michigan commercialization spinouts specifically, we address the research-data handling obligations that carry over from academic context to commercial context.
Do you have an Ann Arbor office?
Not currently. We operate from our Tiffin, Ohio headquarters and serve Ann Arbor clients through a remote-first model with on-site coverage coordinated through the sponsor engagement and regional partners. For Advantage and Alpha tier engagements, on-site cadence is established during scoping.
Can you name your Ann Arbor sponsor client publicly?
We reference the engagement anonymously on public content. Named references are available under NDA or with the sponsor's explicit approval. This is the discipline we apply to every client and it is part of how we operate as a trusted partner to sponsor-backed operators.
