Full disclosure: Zorexo wrote this list, and Zorexo is on it. I've kept the other entries to what each company says publicly about itself, and I've said when another option is a better fit than us. Check each one yourself before you sign anything.
What to look for in a client acquisition partner
Tech recruitment is a hard market to prospect into. Engineering leaders get pitched constantly, and most pitches arrive after the role is already on every job board. A good partner fixes timing and relevance, not just volume. Look for these five things.
- Signals, not static lists. Do they pick targets based on a real hiring need, like a new CTO, a funding round or a role that won't fill?
- The right person. Do they reach the hiring manager who owns the role, or the HR inbox?
- Tech fluency. Can their messages mention a stack or a team without sounding fake?
- More than email. LinkedIn and calls matter in recruitment. Email alone leaves meetings on the table.
- Ownership. When you stop working with them, do you keep the domains, the data and the workflows?
The list
Best for agencies that want signal-led outbound
1. Zorexo
Signal-led outbound for recruitment agencies, built and run by an ex-recruiter who has sat on every side of the hiring desk: in-house, agency, executive search and agency owner.
- What they do
- Weekly hiring signal lists, verified hiring managers, and email, LinkedIn and call outreach that opens on the signal. Client and candidate acquisition.
- How you work
- "We build it" (one-time setup inside your own accounts) or "We run it" (monthly, done for you).
- Free offer
- A client hit list: 10 companies hiring in your niche, the hiring manager at each one and the first message to send.
- Good to know
- A small, hands-on team. If you want thousands of emails a day, a bigger agency will suit you better.
Best for owners who want a framework and community
2. RecruiterGTM
Positions itself around a 5-pillar GTM framework for recruitment agencies, aimed at owners doing $10k to $50k a month.
- What they do
- Systems, an academy, a mastermind and a community, plus done-for-you options. Their site says they've audited 650+ recruitment agencies.
- Good to know
- A strong fit if you want to learn and build alongside other owners. Less of a fit if you just want meetings without the learning curve.
Best for larger firms that want an established provider
3. Sopro
A large, established B2B lead generation company with a dedicated page for recruitment and staffing firms.
- What they do
- A campaign team that handles strategy, data, outreach and optimisation, mainly through email. Recruitment case studies on their site include Coface, Copyhouse and On It.
- Good to know
- Strong review scores across G2, Capterra and Clutch. Their messaging covers many industries, so it's less tech-recruitment specific.
Best for staffing firms that want a fast launch
4. LeadHaste
An outbound agency with a dedicated staffing and recruiting offer built around hiring signal targeting.
- What they do
- Targets hiring managers at companies with active roles, with multi-touch outreach. Their staffing page says setup and tooling are included, the system goes live in 14 days and the infrastructure is registered to you.
- Good to know
- Covers many industries beyond staffing. Good if you want a broad outbound team.
Best for firms that want job-post-led outbound
5. KNK Outbound
A signal-driven outbound agency that uses open job postings as the main buying signal for recruiting and staffing firms.
- What they do
- Cold email, LinkedIn outreach and content. They list tools like Smartlead, HeyReach, Clay, Apollo and Trigify, and offer a free GTM audit.
- Good to know
- Job posts are a strong signal but a crowded one. Ask how they stand out when ten other agencies saw the same post.
Best if you have time and a tech-savvy team
6. Build it yourself
Clay for signals and enrichment, a sending tool like Instantly or Smartlead, HeyReach for LinkedIn and your CRM for follow-ups.
- What it takes
- Separate sending domains, a few weeks of warm-up, weekly list building and someone who keeps it running when the desk gets busy.
- Good to know
- Cheapest on paper. The hidden cost is the hours, and BD stopping every time you get busy.

Questions to ask before you sign
- Which signals do you use to pick targets, and how often is the list refreshed?
- Who exactly do you contact at each company, and how do you verify the email?
- Can I see three real first messages you'd send in my niche?
- Whose domains and inboxes do you send from, and who owns them if we stop?
- How do replies reach me, and can they be logged in my CRM?
- What happens in the first 30, 60 and 90 days?
A partner who can answer all six clearly is worth a call. If you want to see how Zorexo answers them, start with the recruitment lead generation page.
