At what point does a startup need HR? 20 employees? 50? 100?

There is no magic number.

For some companies, HR becomes a priority at 15 employees. For others, they can operate without dedicated HR support for much longer.

Headcount isn’t the best way to decide when you need HR. Time is.

More specifically,how much time are your founders and managers spending dealing with people issues instead of growing the business?

If your leadership team is spending hours figuring out compensation, handling employee conflicts, writing policies, training new managers or trying to understand why people are leaving, you may already need HR support.

Here are five signs it’s time to stop treating HR as something you’ll “figure out later.”

1. Your managers are becoming people managers without training

Your best individual contributor gets promoted to manager.

Congratulations! And then you give them a team of five people and expect them to know how to manage performance, give feedback, handle conflict, run one-on-ones and have difficult conversations.

Because they were great at their previous job.

Sound familiar? This is one of the most common growing pains in startups.

Being a great engineer doesn’t automatically make someone a great IT manager.

Being an excellent salesperson doesn’t automatically teach someone how to manage performance.

As your startup grows, your managers become a critical part of your employee experience. But many first-time managers receive little or no training before taking on the role.

The result can be inconsistent management across teams.

One manager gives regular feedback, another avoids difficult conversations.

One has clear expectations for their team, another assumes everyone knows what “good performance” looks like.

One handles conflict quickly, another lets it become a much bigger problem.

What we can do

HR doesn’t need to manage your managers for them.

Instead, HR can give managers the tools and structure to do their jobs well:

• Manager training
• Clear performance expectations
• One-on-one frameworks
• Feedback and coaching tools
• Performance management processes
• Support for difficult conversations
• Clear escalation guidelines

If your managers are learning people management through trial and error, it’s probably time to bring in some HR expertise.

2. Employees are leaving sooner than expected

Turnover is not always a problem. People leave companies. Careers change. Life happens.

But if you’re consistently losing employees shortly after hiring them, it’s worth paying attention.

Especially if you’re losing people you expected to stay.

Early-stage companies often focus heavily on hiring.

“We need to hire faster.”

“We need more people.”

“We need to fill this role.”

But hiring is only half of the equation.

Can you keep the people that you hired?

If employees are leaving after six months or a year, you need to understand why. Is the job different from what they expected? Are managers struggling? Do we have favoritism? Is compensation no longer competitive? Is there no clear path for growth? Are employees burning out? 

What we can do

Hoom can help you move from guessing to understanding.

That might include:

• Exit interviews
• Employee surveys
• Stay interviews
• Manager feedback
• Retention analysis
• Career development frameworks
• Compensation reviews
• Employee experience improvements

The goal isn’t to prevent every resignation.

It’s to understand which departures are normal and which ones are telling you something about the organization.

If you’re repeatedly replacing the same roles, the cost isn’t just recruitment. It’s lost productivity, lost knowledge and more pressure on the people who remain.

3. Founders are still approving every people decision

This one is a big one.

A founder is approving every salary increase, involved in every performance issue, needs to approve every promotion, gets pulled into every employee conflict.

A founder is answering questions about vacation, benefits and policies.

At 10 employees, this might be manageable. At 30 employees, it becomes a bottleneck. At 50 employees, it can become a serious organizational problem.

Your founders should be building the company, not acting as the company’s unofficial HR department.

The issue isn’t that founders shouldn’t be involved in people’s decisions.They absolutely should be involved in the decisions that matter. 

What we can do?

A good HR function creates clarity around:

• Who can make which decisions
• How promotions are evaluated
• How compensation changes are handled
• How performance issues are managed
• When HR needs to be involved
• When managers can make decisions independently
• Which decisions require leadership approval

The goal is not to remove founders from the people’s side of the business. It’s to give them their time back while making the organization more consistent.

4. You create policies only after something goes wrong

“Do we have a policy for that?” Usually asked after something happens.

Someone takes an extended leave. Someone asks to work remotely from another country.A manager wants to fire someone. An employee requests a salary adjustment. Suddenly, everyone realizes there isn’t actually a process for handling the situation. So the company creates a policy.

Then another situation happens. Another policy. Then another.

This is what we call reactive HR.

And it’s completely normal in the early days of a startup. The problem is when it becomes the way your company operates.

What we can do

Hoom helps you anticipate the situations you’re likely to encounter as you grow.

That might include creating clear frameworks for:

• Vacation and time off
• Remote and hybrid work
• Performance management
• Workplace conduct
• Compensation
• Promotions
• Leave management
• Recruitment
• Onboarding
• Terminations
• Employee complaints

Not every startup needs a 100-page employee handbook. In fact, more policies don’t necessarily mean better HR. The goal is to have the right policies and processes for your stage of growth  before you desperately need them.

5. You’re making compensation decisions on the fly

What we can do

You don’t necessarily need a sophisticated compensation philosophy from day one.

But you do need some consistency.

At Hoom, we can help establish:

• Salary ranges
• Job levels
• Compensation benchmarks
• Promotion criteria
• Salary review processes
• Bonus structures
• Total rewards principles

The best time to build HR isn’t when you have an HR problem. The best time to build your people’s infrastructure is before growth exposes the cracks.

So if your startup is growing and you’re starting to recognize yourself in these five signs, don’t wait for the next employee issue to force the conversation.

Your company may not need a full HR department yet. But it might be time for HR.
