The Platform
One firm. Three conversations.
Whether you built the company, back the people who buy it, or represent the owner, the conversation starts with a principal.
For Capital Partners
We work with a limited group of family offices and institutions with whom we have an established relationship. Each acquisition is capitalized on its own terms.
Existing relationshipsFor Intermediaries
Brokers, advisors, attorneys and accountants get a direct line to a decision-maker, a prompt answer and respect for the relationship you hold with the owner.
Submit an opportunityFrom the Founder
“The measure of what you build is whether it is still standing — and still growing — long after you have stepped away.”
I come from a family that measures success in generations, not quarters. Land and businesses were passed down because, at every turn, someone decided they should be. That idea shapes every decision I make as an investor.
Across America, a generation of owners is approaching the same moment. They built the companies that keep their communities running — the contractors, manufacturers, clinics and service firms people depend on every day. Too many of those companies will be sold to whoever bids highest and dismantled by whoever cares least.
Neirastream exists to be the other option. We acquire with conviction and pay fairly. We keep what makes a company special. And we bring the capital, systems and discipline to take it further.
We are not building a business to flip. We are building institutions — here, in American communities, for the long term.

Thesis
Why these companies, and why now.
Six convictions guide what we buy and how we own it.
Essential demand
We buy businesses customers cannot defer: a furnace that fails in January, a roof that leaks, a set of books that must close.
The succession gap
A generation of owners is ready to step back, and many have no family member or manager positioned to take over. A prepared buyer solves a real problem.
Fragmented markets
Our sectors are made up of thousands of independent operators. A well-run platform can add neighboring companies one careful step at a time.
Professionalize, don't strip
Value comes from better systems, reporting, pricing and recruiting — not from cutting the people and service that earned the reputation.
Conservative structures
We size debt to what a business can carry in a slow year, and we favor structures that keep sellers and managers aligned with the outcome.
Long-term ownership
We underwrite to hold. Decisions are made for the company a decade from now, not for a sale date.
Process
A clear path from first call to closing.
Owners deserve to know what happens next. Every conversation follows the same six steps.
Introduction
A confidential conversation with a principal about your company, your goals and your timeline. No documents required.
Confidential review
We sign a non-disclosure agreement before you share any financial information, then review a short set of summary materials.
Indication of interest
Within [10] business days of receiving summary financials, we tell you whether we are a fit and, if so, outline value and structure in writing.
Diligence
A focused review of financials, customers, operations and licensing, scheduled around the demands of running your business.
Agreement & closing
Definitive documents, financing and a closing timetable agreed in advance, with a transition plan written alongside them.
Transition & build
You stay as long as you and the business need. We invest in people, systems and growth from the first day of ownership.
Intelligence
Disciplined underwriting, the same way every time.
Every opportunity is examined through a fixed set of lenses before capital is committed. The discipline protects sellers, lenders and co-owners alike.
The Lenses
- Quality and durability of earnings
- Customer and supplier concentration
- Workforce depth and key-person reliance
- Licensing & regulatory review
- Capital structure and lender fit
- Integration and systems readiness
Regional Focus
American markets. Local relationships.
We start where we live and work outward through markets where we can be present, build relationships with owners and lenders, and manage what we own.
Headquarters
Colorado
Denver base for the investment team, lender relationships and portfolio operations.
Mountain West
Utah & Arizona
Fast-growing regions with deep pools of established trade and service businesses.
South Central
Texas
Scale, population growth and fragmented essential-service markets.
Southeast
Georgia & the Southeast
Owner-operated companies facing succession across a growing region.
For Owners
You built it. We intend to keep it standing.
Selling a company you spent decades building is not only a financial decision. We structure each transaction around what matters to you.
Your people stay
We buy companies for the teams that run them. Employees, managers and customer relationships are the asset.
Your name stays
The reputation on the trucks and the front door took years to earn. We keep it.
Your timeline
Step away at closing, stay for years, or anything in between. The transition plan is written with you.
A straight answer
You deal with a principal from the first call. If we are not the right buyer, we say so promptly.
Structures we use
- Full buyout
- Majority recapitalization
- Partner buyout
- Staged succession
- Retained equity
- Seller-financed acquisition
Leadership
Principals, not intermediaries.
The people you speak with are the people who decide.

Founding Advisors
Help shape it from the start.
Neirastream is a Denver-based, principal-led firm that acquires and builds founder-owned American companies across essential services: mechanical and building trades, specialty manufacturing, healthcare services, and business and infrastructure services. We are looking for seasoned operators, dealmakers and professionals who have built, run, financed or sold companies in these industries to help us source, evaluate and integrate acquisitions.
We are assembling a board of directors, supported by experienced legal and accounting counsel. Founding advisors are granted founder equity at no cost, vesting over four years, with a path to a full board seat for those who earn it.
