Turning What You Sell Into a List of US Companies That Need It

To find US companies that need your product, write a buyer profile before you search. A buyer profile names the industries that use your product, the NAICS codes for those industries, the company sizes that buy in useful volumes, and the signals on a company's website that prove the need. With that profile, any directory or data tool gives you a short, relevant list instead of a long, random one.

This guide shows how to build that profile from a plain description of what you sell, how to test it, and how to avoid the most common targeting mistakes.

What is a buyer profile?

A buyer profile, sometimes called an ideal customer profile, is a short written description of the companies most likely to buy from you. For B2B suppliers it has five parts:

• Product in plain words: what it does and for whom, without catalog jargon.
• Industries: the sectors that use it, mapped to industry codes.
• Company size: employee range, number of sites or production volume.
• Signals: facts on a company's website that show a likely need.
• Exclusions: companies that look similar but will not buy.

The profile is a working document. You will change it after your first batch of outreach shows who actually replies.

Takeaway: if two people on your team would build different lists from your profile, it is not specific enough yet.

How do you describe your product in plain words?

Start with the job the product does, not its name. Answer three questions in one or two sentences each:

1. What problem does it solve? For example, "reduces downtime on packaging lines caused by worn conveyor chain".
2. Where is it used? "In food and beverage plants and contract packagers."
3. Who notices when it is missing or failing? "Maintenance managers and line supervisors."

Compare "We manufacture high-quality stainless steel chains" with "We make stainless conveyor chain that lasts longer in wash-down areas of food plants". The second sentence already names an industry, a setting and a buyer.

How do you turn a product into industries and NAICS codes?

NAICS, the North American Industry Classification System, groups US businesses by what they do. Codes run from two digits for a broad sector to six digits for a specific industry. Manufacturing is sectors 31 to 33, construction is 23, and wholesale trade is 42.

Map your product to the industries that use it, then find their codes. Here are illustrative examples, not real customers:

Codes are a starting point, not the final list. Companies choose or are assigned codes that may not match everything they do, so always confirm the signal on the website.

Which company sizes should you target?

Size changes how a company buys. A useful rule is to match company size to your order size and your ability to support the customer.

• Small companies (roughly 10 to 50 employees): owner decides, fast decisions, small orders, little process.
• Mid-sized companies (roughly 51 to 500 employees): a few decision makers, more regular orders, basic supplier approval.
• Large companies (500 employees and up): buying groups, formal supplier approval, longer cycles, bigger volume.

Secwyn's manufacturing directory and construction directory show employee size bands for the companies in its verified data, as of 2026-10-06. Most companies on those pages fall in the 51 to 200 employee band, which is a common sweet spot for suppliers: big enough to buy steadily, small enough to reach the decision maker.

Which signals prove a company needs your product?

Signals turn a list of possible companies into a list of likely buyers. Good signals are specific and can be checked on the company's own website.

• Process signals: "in-house powder coating", "5-axis machining", "blow molding".
• Channel signals: "sold through authorized dealers", "find a distributor".
• Market signals: "serving aerospace and defense", "SQF certified facility".
• Activity signals: trade-show booths, new product launches, expansion news, open jobs.
• Ownership signals: "family-owned since 1978" or "a division of" a larger group, which changes who decides.

Weak signals are generic phrases like "quality products" or "customer focused". They appear on nearly every website and tell you nothing.

Qualifying B2B leads from company websites explains how to turn these signals into a simple fit score.

Step by step: building and testing your buyer profile

1. Write the plain-words description of your product using the three questions above.
2. List three to five buyer industries and find their NAICS codes.
3. Set a size range that matches your order size and support capacity.
4. Write three to six signals a company website would show if the company needs you.
5. Write exclusions, such as "importers only" or "retail stores".
6. Pull 20 sample companies and check each against the signals by hand.
7. Count the hits. If fewer than half fit, tighten the industries or signals. If almost all fit but the list is tiny, loosen one rule.
8. Run a small outreach test and update the profile based on who replies.

Secwyn does steps 1 to 6 for you. You describe what you sell in plain words, and it drafts a buyer profile with industries, company size and signals such as running its own plants, selling through dealers or exhibiting at trade shows. You review and edit the profile, then it ranks US companies as Strong, Good or Possible fits, each with reasons and quotes from the company's website.

Common targeting mistakes to avoid

• Targeting a whole sector. "Manufacturing" is not a buyer profile.
• Trusting the industry code alone. A company coded as a machinery maker may now only distribute.
• Ignoring the channel. If your product is usually bought through distributors, end users may simply refer you to their supplier.
• Skipping exclusions. Without them, competitors and importers fill your list.
• Never updating. The first profile is a guess. Replies and objections tell you how to fix it.

Once your list is ready, the next challenge is reaching the right person. See finding decision makers at US companies, and for the full process from profile to first order, how to find buyers in the USA. The company directory home page shows all the industries Secwyn covers.

Frequently Asked Questions

What is the difference between a buyer profile and a buyer persona?

A buyer profile describes the companies most likely to buy: industry, size and signals. A buyer persona describes the people inside those companies: their role, goals and daily problems. You need the profile first to build the company list, then personas to decide who to contact and what to say to each role.

How specific should my NAICS codes be?

Use six-digit codes when your product serves a narrow industry, such as machine shops, and broader four-digit groups when it serves several related industries. Always test a sample of companies from each code by hand, because codes are assigned imperfectly and some companies do more or less than their code suggests.

What if my product fits almost every industry?

Pick the two or three industries where you have the strongest proof, such as existing customers, certifications or a clear cost saving. Start there and expand later. A focused start lets you write specific messages and learn quickly, while a broad start usually produces generic outreach and few replies.

How do I find signals if a company's website is thin?

Check its news page, careers page, certifications and any trade-show listings. Look at photos of the shop floor and product pages for clues about processes. If the evidence is still missing, mark the signal "not confirmed" rather than guessing, and decide whether the company is worth a short question by email.

How many companies should a good buyer profile produce?

Enough to keep your outreach busy for a few months, but not so many that you cannot check fit. For many suppliers that means a few hundred well-matched US companies to start. If your profile returns tens of thousands, it is probably too broad to be useful.

Can I have more than one buyer profile?

Yes. Many suppliers sell to end users, distributors and OEMs, and each needs its own profile because the industries, signals and decision makers differ. Keep them separate, run outreach for each one separately, and compare reply rates so you know where to focus your time.
