IT Due Diligence and Integration for Acquisitions

I help search funds, business brokers, and private equity buyers find the technology risk before closing and fix it after. You get security reviews, data migrations, and system integrations from one hands-on consultant with ten years in cybersecurity.

How I Help Buyers and Sellers

Most small businesses run on a patchwork of tools, old hardware, and one IT person’s memory. I map that patchwork before the deal and move it onto the buyer’s systems after.

Pre-Close IT Due Diligence

I review the target's systems, backups, user access, licensing, and vendor contracts before you sign. You get a plain-English list of risks and what each one costs to fix.

Cybersecurity Due Diligence

I check endpoint protection, email security, backups, and breach history, then tell you what has to change before close and what can wait until after.

Post-Acquisition IT Integration

I move users, devices, and data onto your standard stack: RMM and endpoint security swaps, cloud backup and file migrations, Microsoft 365, and NetSuite.

Sell-Side IT Readiness

Selling soon? I clean up your systems before buyers look, so their diligence team finds fewer surprises and your price holds.

The two companies I put most of my time into today.

Esimplicity Technologies

Founder and Principal Consultant

My managed IT and consulting firm in Thornton, Colorado. My team runs networks, endpoint security, email security, backups, websites, and helpdesk for businesses in Colorado and California. The companies we support bring in more than $800 million a year combined.

Common Questions

What does IT due diligence cover?

I look at network and endpoint security, backups and recovery, user access, software licensing, vendor and SaaS contracts, and where the company’s data lives. You get a list of risks, what each one costs to fix, and what should happen before and after close.

When should I bring you in?

As early as the letter of intent. The sooner you see the tech picture, the fewer surprises you hit in the final weeks. I also help sellers clean up their systems before they go to market.

Who do you work with?

Search funds, independent sponsors, business brokers, small private equity firms, and owners getting ready to sell.

Can you run the migration after closing?

Yes. I have scripted RMM and security agent swaps, moved cloud backups, restructured legacy data to fit a buyer’s systems, and supported NetSuite rollouts. I can lead the work or slot in beside your IT team.

Where are you based?

Denver, Colorado. I run most engagements remotely with my own secure remote-support tools and work on-site in the Denver area when a project needs it.
