Census does not publish a separate category for commercial interior and office design firms; figures use NAICS 541410, Interior Design Services, the closest official industry. 93.8% of establishments have fewer than 10 employees, so most firms in the industry run outbound with a founder or a very small sales team. The 1,041 firms with 10 to 249 employees are the ones most likely to be building a repeatable outbound process.
The five largest states hold 49.7% of all establishments. Among states with at least 100 establishments, the fastest growth between 2022 and 2023 was in Oklahoma (+14.0%), Tennessee (+11.6%) and Oregon (+11.5%). Growing markets bring new competitors and new buyers at the same time, which rewards outreach that is specific rather than volume-driven.

How office design firms should run cold email
Commercial interior and office design firms sell workplace design, fit-out and furniture programmes to companies changing or expanding their space. These are the contacts, triggers and messages that make a first email relevant rather than generic.
Who to email
- COO or head of operations
- Facilities or workplace manager
- Managing partner at professional firms
- HR lead for workplace experience
Signals worth researching
- Office moves, new leases or new regional offices
- Rapid hiring that strains current space
- Return-to-office or hybrid policy changes
- Rebrands that extend to the physical workspace
What to say
- Reference the move, expansion or policy change you found
- Talk about how people will use the space, not furniture specifications
- Offer a short planning conversation before decisions lock in
What to avoid
- Product catalogue attachments
- Assuming a move is happening without a public signal
Cold email for office design firms, answered
How many office design firms are there in the US?
There were 16,797 establishments in NAICS 541410 (Interior Design Services) in 2023, employing 55,286 people. Source: U.S. Census Bureau, County Business Patterns 2023.
Which states have the most office design firms?

When is the right time to contact a company about office design?
Early in a space decision: when a company announces a move, signs a new lease, opens an office or changes its work policy. Reaching out before the layout is decided is far more effective than contacting them after a contractor is chosen.
Who decides on office design projects?
Operations leaders, facilities or workplace managers, and at professional firms the managing partner. Larger projects often involve the CFO and HR as well.
Is cold email legal in the United States?
Yes. The federal CAN-SPAM Act permits commercial email to business contacts without prior consent, provided the message identifies the sender accurately, uses a truthful subject line, includes a valid physical postal address and a working opt-out, and honours opt-out requests promptly. CAN-SPAM applies in every state and preempts most state commercial email laws, except provisions aimed at falsity or deception. This is general information, not legal advice.
