When does a climate start-up or scale-up need a recruitment partner? Rarely because of one dramatic moment. It's usually a combination of signals: the company is growing, hiring the old way is starting to break down, and something external makes the timing obvious. A funding round, a regulation, a certification. Here are the eight signals we see most often at climate tech and other impact-driven companies, grouped into three categories: organisational, market, and sector or funding related.
1. Your first People or HR hire just started
When an organisation makes its first dedicated People or HR hire, recruitment is often the first thing on their plate, and the thing they have the least experience with. A new People hire inheriting 4 or 5 open roles with no structured process behind them is a common, and avoidable, way to start.
2. You've announced a funding round
A funding round typically comes with a hiring plan attached: new roles across finance, operations, and commercial functions, often needed within a specific runway window. This is exactly the kind of concentrated, time-pressured hiring a pre-purchased vacancy package is built for, since the price per vacancy is agreed upfront and doesn't escalate the way a per-placement agency fee does.
3. Your own recruiter vacancy has been open for 2+ months
If an organisation is trying to hire its own in-house recruiter and that vacancy itself has been open for months, that's a strong signal the hiring need has outgrown ad hoc solutions, but the volume may still not justify a full-time hire. A structural partner can fill the gap in between.
4. You, the founder, are still posting vacancies on LinkedIn yourself
A founder who is still personally posting job ads and screening CVs is spending time on a repeatable process that could be handled structurally. This is less about the time cost of any single vacancy, and more about the opportunity cost of the founder's attention across a growing number of them.
5. You're switching recruitment agencies
Organisations that switch agencies are usually reacting to one of two problems: inconsistent quality, or an escalating per-placement fee as hiring volume increases. A pre-purchased package with a fixed price per vacancy addresses both: predictable cost known upfront, and one consistent process across every hire.
6. You have multiple vacancies open across several platforms at once
Multiple concurrent vacancies scattered across different job boards or agencies is a sign that hiring has outgrown a single-vacancy mindset, without yet having a structural process behind it. Consolidating that volume with one recruitment partner, rather than juggling several parallel processes, tends to reduce both cost and management overhead.
7. You've secured national or EU funding, or won a public tender
Funding and grant schemes such as SDE++, RVO, or the Nationaal Groeifonds in the Netherlands, the EU Horizon and Innovation Fund, InvestNL, or comparable schemes elsewhere in Europe, often come with delivery timelines that require a specific team to be in place by a certain date. The same applies to winning a public tender: the award frequently comes with a staffing commitment attached. Both create sudden, deadline-driven hiring pressure.
8. You're preparing for CSRD reporting, or B-Corp or EcoVadis certification
Sustainability reporting and certification requirements are, indirectly, a hiring driver. Preparing for CSRD reporting, or working towards B-Corp or EcoVadis certification, often surfaces gaps in finance, compliance, and sustainability roles that need to be filled alongside the reporting work itself, not after it.
What these signals have in common
None of these signals, on their own, means an organisation needs a full-time in-house recruiter. Most of the organisations we work with hire enough roles a year to make ad hoc hiring expensive and slow, but not enough to justify a full-time recruitment hire of their own. That's the specific gap a pre-purchased vacancy package is built to fill: structural hiring capacity, without the fixed cost of an employee, and without the escalating cost of a per-placement agency.
If two or three of these signals sound familiar, it's worth a conversation. We'll tell you honestly whether a recruitment partner makes sense for where you are, and if it doesn't yet, we'll say so.
