How do recruitment agencies get clients? Business development that hiring managers answer

Recruitment agencies find new clients in four places: companies they have placed people with before, candidates they placed who now hire, referrals from those people, and companies that are hiring right now in the agency’s specialism. The first three grow with time. The fourth is what keeps a new desk or a new agency alive in its first year.

The market is crowded. The American Staffing Association counts around 27,000 staffing and recruiting companies operating close to 54,000 offices in the US (2021 figures, read on its statistics page on Oct 19, 2026). A hiring manager with an open role often hears from several agencies in the same week, so the agency that wins is the one with a reason to call that the others do not have.

Contingency agencies are paid only when a candidate they present is hired, so their business development is about speed and the number of live roles; retained agencies are paid to run a search, so theirs is about access and timing.

• Contingency: you often compete with other agencies and the company’s own recruiters on the same role. Win more by being first with a strong candidate, and by choosing roles you can actually fill.
• Exclusive or engaged contingency: the company gives you the role alone for a period. Win this by showing a short, credible view of the market before you ask for exclusivity.
• Retained: the company commits before the search starts. Win this months earlier, with a relationship and a point of view; see executive search business development for the leadership events that start those searches.

Many agencies do all three. The mistake is running one playbook for all of them, such as cold-calling for retained work or waiting months for a relationship on a contingency role that will be filled next week.

A recruitment agency should specialize, because a hiring manager chooses the recruiter who already knows the candidates, the pay and the competitors for the role.

A specialism is a role family plus a market: maintenance and reliability engineers for food plants in the Midwest, or controllers and finance managers for private-equity-backed companies. It is narrow enough that you can name 50 strong candidates from memory, and wide enough that the companies hiring them open roles every month.

1. Start where you have already placed people. Your first clients will come from the market where your candidates and references are.
2. Check the demand: are companies in that market posting these roles often, and do the roles stay open?
3. Check the fee: will companies in that market pay an agency for this role, or do they fill it themselves?
4. Write it down as a short profile of the client you want, with the roles, the industries, the sizes and the regions.

The hiring signals that show a company needs a recruiter are the ones that mean its own team cannot keep up: a burst of posts in one function, roles left open or reposted, and the events that create many roles at once.

Open roles alone do not pick a client. The US had 7.1 million job openings in August 2026, according to the Bureau of Labor Statistics’ Job Openings and Labor Turnover Summary released Sep 29, 2026. Most of them will be filled without an agency. What you are looking for is the subset in your specialism where something about the company makes the hiring hard.

Check every signal on the day you reach out. A role filled last week is not a reason to call, and a hiring manager can tell when an agency is working from an old list.

Recruiters should pitch from open job postings only when the role is in their specialism, the post shows the company is struggling to fill it, and the pitch adds something the company’s own applicants cannot.

A post that went up yesterday is usually being handled by the company’s own team, and every agency that reads job boards will call about it. The better postings to act on are the ones other agencies skip:

• Reposted roles, or roles still live after two months: the company has tried and failed.
• Several roles in one function at once: the team cannot screen them all.
• Roles at a new site: the company has no local network there yet.
• Roles with rare requirements, such as a certification or a specific system, that match candidates you already know.

Read the post before you call. If it says the company does not accept agency submissions, respect it, and note the company for a later conversation with talent acquisition instead.

A recruiter should usually contact the hiring manager, the person who will manage the new hire, because that person feels the open role every day; talent acquisition and HR decide which agencies get to work on it.

Going around a talent acquisition team that controls its agency list can cost you the account. Reach the hiring manager with market knowledge, and be open about bringing talent acquisition in when the role becomes real.

Spec CVs or resumes sent in bulk to companies with no open role mostly get ignored, because they arrive without a role, a reason or a request the hiring manager can act on.

A spec resume works only in a narrow case: the company has a live role, the candidate is a close match, and the candidate has agreed to be put forward to that company. Outside that case, send knowledge instead of people:

• How many people with this profile are in the area, and how many are open to a move.
• What similar companies are paying, in ranges you can stand behind.
• Why the role has stayed open elsewhere, from your own recent searches.
• One anonymized example of a candidate you could present, offered rather than attached.

The business development tactics that work for agency recruiters are steady and specific: a short named list of target companies, regular contact with past clients and placed candidates, and outreach timed to a hiring signal.

1. Keep a named list of a few dozen target companies in your specialism, each with the reason it is on the list. Review it every month.
2. Go back to past clients and dormant accounts. A hiring manager who used you two years ago may have new roles, or may have moved to a company that does.
3. Stay in touch with every candidate you placed. They are your best source of references, referrals and future roles.
4. Book business development time on the calendar every week, including the weeks you are busy filling roles. That is when the pipeline usually runs dry.
5. Lead with the market: pay ranges, candidate availability and why similar roles stay open. It is the reason a hiring manager takes the call.
6. Write down why each company said no or not now, and when to try again. A dated “not this quarter” is a lead for next quarter.

A recruiter should write a business development email about the company’s own hiring, with the dated post or event that shows it, one thing the hiring manager does not know about the market, and one easy question.

A sample email from a recruitment agency

Fictional sample. Halvorsen Castings is a fictional manufacturer in Toledo, Ohio. A county permit dated Sep 12, 2026 approves a 140,000 sq ft foundry expansion in Dayton, and on Oct 6, 2026 the company posted four supply chain roles for the new site. Mark Delacroix is its VP of supply chain. The sender works at a fictional agency that places supply chain people in metals.

Subject: Dayton buyer and planner roles. Hi Mark, I saw the four supply chain roles for Dayton posted on Oct 6, including two senior buyers and a materials planner. Buyers with foundry experience within an hour of Dayton are a short list, and roles like these tend to stay open when the search starts after construction does. I keep a current map of supply chain people in castings and forgings in the region, with typical pay ranges; I would be glad to send it. Are you hiring these yourself, or is your talent team running them? Jordan Lee, [Agency name], [street address, city, state ZIP]. If this isn’t relevant, just reply and I won’t follow up.

Fictional sample: company, people and agency are fictional.

• Subject: names his roles, not your agency.
• Opening: the dated posts, which he can check in a second.
• Point of view: what is hard about this hire in this market, from your own searches.
• Offer: a market map he can use even if he never hires you. No resumes attached.
• Question: tells you who owns the hire, which is useful either way.

SalesOne is AI account research and qualification. It finds the companies in your specialism where a dated event makes hiring hard, and your recruiters keep every conversation. See how SalesOne works for professional services firms and what S1 agents research on each account.

S1 deep research agents keep or turn down each company they check against your client profile, with the reason, and find the hiring manager and the talent lead for each company they keep. Current clients and companies you have agreed not to recruit from go on an exclusion list. A person approves every message, and every approval is recorded with who gave it.

Because hiring signals go stale fast, the dates matter. In SalesOne’s own runs, four production runs in October 2026, all 375 buying signals link their source and 98% are dated to the day, and S1 agents ran about 31 searches and read about 7 pages for each account kept. The method is on how we measure S1 research.
