MSA celebrates six straight appearances among America’s fastest-growing private companies in its 10th year of business.
For the sixth consecutive year, Market Square Architects (MSA) has earned a place on the Inc. 5000 list of America’s fastest-growing private companies.
The annual ranking measures three-year revenue growth among privately held businesses across all industries nationwide. MSA has appeared on the list every year since 2021, an achievement that reflects sustained growth through changing economic conditions and development markets.
Founded in Portsmouth, New Hampshire, in 2016, MSA has spent the past decade building long-term client relationships, expanding its geographic reach, and strengthening its expertise across residential and commercial architecture. Today, the firm serves projects nationwide from offices in Portsmouth, Nashville, and Austin.
For MSA, growth isn’t simply about becoming a larger company. It’s about building the people, experience, and resources to support our clients as their projects and businesses evolve, while preserving the responsiveness and personal relationships they value.
Six consecutive years on the Inc. 5000 is a milestone we’re proud of, and one we’re fortunate to share with the clients, partners, and employees who continue to make our growth possible.
