Understanding the Inc 5000 List
The Inc 5000 is more than a ranking—it celebrates entrepreneurial spirit. Launched to spotlight the fastest-growing private businesses in America, the list provides a snapshot of which companies are breaking through barriers and achieving extraordinary results.
What makes the list unique is its focus on three-year revenue growth. While many business awards recognize size, profit, or innovation, the Inc 5000 looks at momentum—how quickly a company can expand while still maintaining independence and agility. Companies on the Inc 5000 list are not public; they are privately held and not publicly traded.
Being included is a mark of prestige and recognition. For companies, it shows investors, partners, and customers that the business has not only achieved success but has sustained it over multiple years.
Criteria to Qualify
Not every business can make the Inc 5000. To qualify, companies must:
- Be generating a minimum revenue of at least $100,000 in 2021 and $2 million by 2024.
- Be U.S.-based, privately held, for-profit, and independent.
- Have been operational by March 31 of the baseline year.
Companies that are divisions or subsidiaries of larger corporations are not eligible.
These requirements ensure the rankings highlight businesses with significant, sustainable growth—not just short-term spikes in operations or revenue.
Some companies achieve the distinction of being listed multiple years in a row, demonstrating sustained growth.

The Journey of Mechanical One
Mechanical One was founded in July 2021 by CEO Jason James during an uncertain economic climate.

Keys to Success: Thinking Ahead
Mechanical One’s rise wasn’t luck—it was the result of strategic foresight and disciplined execution. Several key factors set the company apart:
- Proactive Supply Planning: Anticipating industry-wide shortages in parts and refrigerant, Mechanical One invested early in procurement strategies. This foresight kept projects moving when competitors faced costly delays.
- Marketing Innovation: Rather than relying solely on traditional word-of-mouth, the company invested deeply in creative marketing campaigns. From digital outreach to local sponsorships, these efforts boosted visibility and built strong brand recognition.
- Employee Investment: Recognizing that its team is its greatest asset, Mechanical One developed leadership training programs alongside advanced technical training. This approach sharpened skills, enhanced operations, and created clear career paths for employees, improving retention and morale.
- Partnerships: The company formed lasting partnerships with manufacturers, home builders, and local communities. These collaborations provided steady work pipelines, reliable resources, and a strong reputation within Florida’s construction sector.
By combining preparation with innovation and a long-term vision, Mechanical One avoided many pitfalls that slow growing businesses and positioned itself for sustainable success.
The Role of Services and Subsidiaries
Mechanical One provides a broad range of services, including HVAC, plumbing, electrical, and gas. Offering these under one roof makes the company a one-stop solution for homeowners and builders.
This strategy increases customer loyalty, creates cross-selling opportunities, and strengthens the company’s position in an increasingly competitive market.
The Broader Economic Impact
The Inc 5000 list does more than spotlight individual companies—it illustrates broader trends in the U.S. economy.
The median growth rate for the 2025 list was 169%, highlighting how small and mid-sized businesses are driving job creation and innovation nationwide. Many companies are expanding beyond their local roots, contributing to regional development and reshaping industries. Some companies on the Inc 5000 list are even making an impact across the world, demonstrating a global reach and influence beyond the U.S.
Mechanical One itself is an example of this impact. By planning ahead for supply shortages, building strong partnerships, and investing in training, it not only grew its own business but also created opportunities for vendors, employees, and communities. This ripple effect is exactly what the Inc 5000 list celebrates—businesses that strengthen the American economy from the ground up.
The company’s forward-thinking operations and long-term vision ensure it continues to drive value for stakeholders, from clients to employees, and contributes to economic growth at both local and state levels.
