How Scale-ups Can Build Their Own Hiring System

You're growing fast but don't have a large HR team. Here's how to build a standardized, scalable hiring system.

Door Ingmar van Maurik · Founder & CEO, Making Moves


The scale-up dilemma

You're growing fast. You just closed a funding round, or your revenue is growing organically at 50-100% per year. The ambition is clear: you need to hire 50-100 people this year to hit your growth targets.

But you don't have a large HR team. Maybe 1-2 recruiters, or even no one working dedicated on recruitment. Founders do interviews between meetings, managers screen CVs based on gut feeling, and the entire process lives in a combination of spreadsheets, Slack messages, and random email threads.

The result: hiring becomes the biggest bottleneck for growth. Not the product, not the market, not the funding — but the inability to hire the right people fast enough.

This is the scale-up dilemma: you have the resources to grow, but not the infrastructure to translate that growth into people. And every month a vacancy stays open costs you revenue, productivity, and market position.

The real costs of disorganized hiring

Before we look at the solution, it's important to quantify the impact:

Direct costs

  • Long time-to-hire (average 45-60 days at scale-ups without a system) means vacancies stay open for 2-3 months
  • High cost-per-hire — without a process, scale-ups rely on expensive recruitment agencies (15-25% of annual salary per placement)
  • Bad hires — hasty decisions lead to [wrong hires costing €50,000-€150,000](/artikelen/how-much-bad-hire-costs)
  • Tool sprawl — separate subscriptions for LinkedIn Recruiter, ATS, assessment tools etc. that don't work together
  • Indirect costs

  • Founder time — every hour a founder spends on interviews is an hour not spent on product, sales, or strategy
  • Inconsistency — without a standardized process, everyone evaluates candidates differently
  • Candidate experience — slow, chaotic processes scare off top talent
  • Employer brand — bad experiences spread quickly in tech communities
  • Turnover — bad hires leave quickly, forcing you to recruit again
  • A scale-up making 80 hires per year with a 20% failure rate loses €800,000-€2,400,000 annually in direct and indirect costs from bad hires alone.

    Why standard tools don't scale

    The typical scale-up hiring stack evolves organically and usually looks like this:

    ToolCostFunction

    |------|------|----------|

    LinkedIn Recruiter€800-€1,500/monthSourcing Basic ATS (Recruitee, Homerun)€300-€800/monthCandidate management Google SpreadsheetsFreeScoring and tracking Calendly€50-€100/monthScheduling Random assessment tool€200-€500/monthIncidental testing Total€1,350-€2,900/monthFragmented

    This works up to 20-30 hires per year. After that, it's chaos:

  • Data lives in silos — candidate information spread across 5+ tools
  • No overview — nobody knows the exact status of every vacancy
  • No consistency — every hiring manager has their own process
  • No learnings — you don't learn from previous hires because data isn't combined
  • Not scalable — every new office, every new role requires manual work
  • The spreadsheet syndrome

    The most telling symptom: if your hiring data lives in Google Spreadsheets, you have a problem. Spreadsheets aren't built for:

  • Pipeline management — who is where in the process?
  • Scoring — how do you objectively compare candidates?
  • Analytics — what's your actual time-to-hire, source-of-hire, cost-per-hire?
  • Compliance — do you meet GDPR requirements for candidate data?
  • Collaboration — who is responsible for which action?
  • The solution: your own hiring system in 4 steps

    Step 1: standardize your flow

    Define one hiring flow that works for 80% of your roles. Specialist roles can have variations, but the base process is always:

    1. Job page — optimized for conversion, mobile-first

    2. Pre-assessmentvalidated tests on cognition, personality, and role-specific skills

    3. AI screening — automatic analysis and ranking of candidates

    4. AI pre-interview — automated first conversation for competency evaluation

    5. Human interview — only with the top 15-20%, structured with scoring rubrics

    6. Offer and onboarding — streamlined process

    The difference from ad-hoc hiring: every candidate goes through the same process, which guarantees comparability, consistency, and fairness.

    Step 2: automate the heavy lifting

    The biggest time savings come from automating the screening phase:

    CV screening

  • AI does the initial selection — no manual reading of hundreds of CVs
  • Skills matching at a semantic level, not just keywords
  • Automatic ranking based on fit with the job profile
  • Pre-assessments

  • Candidates are automatically invited for assessments immediately after applying
  • [Custom assessments](/artikelen/generic-assessments-dont-work) per role type — developers get a different test than sales managers
  • Results automatically processed and combined with CV data
  • Scheduling

  • Automated interview scheduling based on availability
  • No more back-and-forth emailing
  • Candidates choose their own time slot
  • Scoring

  • Objective, consistent scoring for all candidates
  • Weighted criteria based on what predicts success in your organization
  • Ranked shortlists that the hiring manager can review directly
  • Savings: the recruiter spends 70-80% less time on screening and administration, and can invest that time in relationship building and strategic work.

    Step 3: build for scalability

    Your own system grows with your organization — without costs rising proportionally:

  • New role? Add an assessment template and configure the criteria. The system runs
  • New office? Add a location with local job pages. The flow is the same
  • More volume? From 50 to 200 hires per year? The system scales — AI doesn't get tired
  • New department? Copy the base flow, adjust the assessments
  • International? Multilingual job pages and assessments, centralized dashboard
  • Step 4: learn from every hire

    This is what makes your own system unique: it gets smarter over time.

    After every hire, you collect data:

  • Assessment scores vs. actual performance (at 6, 12 months)
  • Which sources deliver the best candidates?
  • Which assessment components best predict success?
  • Where in the funnel do we lose the most good candidates?
  • With continuous validation, your model becomes increasingly accurate. After 50-100 hires, you have a predictive system that significantly outperforms any generic tool.

    What it costs vs. what it saves

    The investment

    A custom hiring system for a scale-up is a one-time investment. The exact costs depend on complexity and features, but the components are:

  • Platform development and configuration
  • Assessment flow setup per role type
  • AI model training based on your existing data
  • Integration with your tech stack (HR system, Slack, etc.)
  • Training and onboarding of the team
  • The savings (annual, at 80 hires/year)

    Savings itemAmount

    |-------------|--------|

    1-2 fewer FTEs in recruitment€60,000-€120,000 Fewer recruitment agencies€100,000-€200,000 Fewer bad hires (5 fewer x €80,000)€400,000 SaaS tool consolidation€15,000-€30,000 Less founder/manager time€50,000-€100,000 Total annual savings€625,000-€850,000

    The ROI is typically 3-6 months — after which the system delivers pure savings.

    Practical example: a SaaS scale-up

    A Dutch SaaS scale-up (Series B, 120 employees) needed to hire 80 people in 2025. Their situation:

    Before their own system:

  • 3 recruiters (2 externally hired via RPO)
  • Average time-to-hire: 47 days
  • Cost-per-hire: €8,500 (including agency fees)
  • Failure rate: 18%
  • Hiring was the #1 bottleneck for growth
  • After implementing their own hiring system:

  • 1.5 recruiters (1 internal + 1 part-time)
  • Time-to-hire: 22 days
  • Cost-per-hire: €3,200
  • Failure rate: 9%
  • Hiring is no longer a bottleneck
  • The impact:

  • €424,000 saved on cost-per-hire (80 x €5,300 difference)
  • 7 fewer bad hires = approximately €560,000 saved
  • 50% faster growth through faster time-to-hire
  • Better quality because every candidate is objectively evaluated
  • Common mistakes scale-ups make

    Starting too late

    Most scale-ups only start building a hiring system when the chaos is already unmanageable — at 60-80 employees. Start earlier: at 30-40 employees, you have enough data to start and still enough time to set up the system before volume peaks.

    Over-investing in separate tools

    Every new tool you add creates a new silo. Instead of buying 5 separate tools, invest in one integrated system that combines everything.

    Not collecting data

    Start from day 1 collecting hiring data: assessment scores, interview evaluations, and — crucially — performance data of hires. Without this data, you can't train models later.

    Unstructured interviews

    Even with the best AI screening: if the human interview is unstructured, you lose all objectivity in the final phase. Use scoring rubrics and standardized questions for every interview.

    Key takeaways

    Scale-ups that wait to build a hiring system pay the price in slow growth, expensive recruitment agencies, and bad hires. The cost of delay is higher than the investment.

    The core points:

  • Standardize your hiring flow for consistency and comparability
  • Automate screening with [AI](/artikelen/ai-replacing-cv-screening) and [validated assessments](/artikelen/valid-reliable-assessment) — save 70-80% of screening time
  • Build for scalability — the system grows without proportional cost increases
  • Learn from every hire — [continuous validation](/artikelen/continuous-validation-hiring) makes your system smarter over time
  • Start early — at 30-40 employees, not at 100
  • The scale-ups that grow fastest and best are those that treat hiring as a system, not an ad-hoc activity.
