Why rapid headcount growth after funding can backfire – and how to get your HR strategy right from the start for scaling success.

Delaying HR strategy until after Series A funding can create serious challenges. Treating HR as a reactive tool – like a fire extinguisher you only break glass on when things go wrong – can seriously jeopardize a startup’s ability to scale effectively and attract investor confidence. By the time the fires are blazing, the cost of repair is exponentially higher.

However, the smartest startups embed HR into their business from early stages. Building solid HR foundations – culture, hiring, compliance – not only prevents costly problems but also builds trust with investors. Here are my 3 reasons why early HR investment is critical for startups aiming to scale and how to do it right.

1. Culture is your growth framework, not just fluff

Founders often delay defining company values and culture and startup culture is often dismissed as “soft” or “nice to have,” but it’s actually the backbone of your company’s ability to grow sustainably. Your startup’s culture defines how your team collaborates, innovates and navigates uncertainty. It’s what keeps your people aligned and motivated when the pace accelerates.

According to a 2023 report by Deloitte, 94% of executives and 88% of employees believe a distinct workplace culture is important to business success, yet only 12% of companies believe they are driving the “right culture.”

VCs don’t just back great products – they back people and teams that can grow together through challenges. A clearly defined and lived culture signals to investors that your startup has the resilience and cohesion to scale.

Advice: Define your core values early and embed them in every process – from hiring to performance reviews. Celebrate wins and milestones to reinforce these values and build trust. Use employee surveys and feedback loops to continuously refine your culture as you grow.

2. Hiring speed ≠ hiring smart

After a funding round, there’s a rush to scale headcount. But without a clear hiring strategy, this growth can backfire.

The U.S. Department of Labor estimates that the cost of a bad hire can be up to 30% of that employee’s first-year earnings. However, the ripple effects – on morale, productivity and culture – can be far more damaging. In contrast, a 2024 LinkedIn Talent Solutions report found that 83% of successfully scaling startups have structured hiring processes, including clear role definitions, objective scorecards and strong employer branding.

Without defined roles, structured interview processes and scorecards, startups fall into the trap of “fast and familiar” hiring – bringing in friends or rushed referrals without aligning skills to strategy.

Advice: Create clear role descriptions and scorecards to evaluate candidates objectively. Standardise interview questions to reduce bias and focus on cultural and skills fit. Benchmark salaries and offer perks like flexible work to compete with established companies.

Implement applicant tracking systems (ATS) to streamline recruitment and analyse sourcing channels to optimise your hiring funnel.

3. Compliance debt is a quiet killer

In the early days, many founders juggle equity promises, contractor agreements and HR documentation informally. It works – until it doesn’t.

One in five startups faces compliance issues during funding rounds that delay or derail deals. Due diligence will expose these issues – and investors are far less forgiving when “easy-to-prevent” mistakes surface late.

Moreover, misclassification of contractors versus employees can lead to hefty fines; for example, the U.S. Internal Revenue Service (IRS) has levied penalties exceeding $1 billion annually for misclassification. On the positive side, startups with structured onboarding see 50% greater new hire retention and 54% higher productivity (Glassdoor). Ignoring compliance early on builds up “compliance debt” that becomes exponentially more expensive to fix later.

Advice: Establish clear HR policies and employee handbooks that cover compliance, workplace conduct and performance management. Regularly audit your contracts and equity agreements to ensure legal compliance and transparency.

Final word

Early-stage HR isn’t about bureaucracy. It’s about building trust – with your team and your investors. It tells everyone that you’re not just chasing a round – you’re building a company.

Don’t wait for Series A to start thinking about HR. Build your culture, hiring processes, compliance and technology infrastructure now. This foundation not only prevents costly mistakes but signals to investors that you are serious about scaling sustainably.
