Why Every Founder Needs a Mentor Who Will Challenge Them, Not Just Back Them Up

When I started building my consultancy, most people around me were supportive.

My team believed in the vision. The people I worked with wanted me to succeed. Everyone nodded along in strategy meetings.

But here was the problem: nobody was questioning my assumptions.

Nobody pushed back when I said "we'll just keep doing founder-led sales for now." Nobody asked the hard question: what happens when you become the bottleneck?

That's why the best founders — and I include myself in this — don't just look for mentors who back them up. They find mentors who challenge them.

In the early stages, I got a lot of encouragement.

But encouragement didn't help me spot the gap in my go-to-market strategy. It didn't tell me my sales process wouldn't scale past ten customers. It didn't warn me that my current approach might cost me later.

A mentor who only validated my ideas felt good in the moment. But six months later, when I was still the only person closing deals and my pipeline was a mess, that validation didn't mean much.

The mentors who actually moved the needle for me were the ones who made me uncomfortable. They asked why I was avoiding hiring a salesperson. They told me my messaging was too vague. They said my GTM strategy wasn't a strategy at all.

That's not negativity. That's clarity.

When I was deep in the day-to-day, it was hard to see what wasn't working.

I was busy. Solving problems. Talking to clients. But I wasn't seeing that:

• You're spending 80% of your time on sales calls instead of building the company
• Your team doesn't have a repeatable process to close deals without you
• Your revenue is growing, but it's not predictable enough to attract Series A investors

A good mentor spots these patterns before they become critical problems.

They've seen other founders hit the same walls. They know what happens when you delay building a real GTM engine. They've watched companies miss their targets because the founder couldn't let go of sales.

And they're not afraid to say it.

Founder-led sales works at the start. I knew the proposition better than anyone. I could answer every objection. I could adapt on the fly.

But it doesn't scale.

The mentor who challenged me most pushed me to think beyond the next deal. He asked:

• What happens when you need to hire a sales team?
• Can someone else replicate your sales process?
• Do you have a go-to-market engine that works without you?

Those questions were uncomfortable because they forced me to admit that what got me here wouldn't get me to the next stage.

The best mentors I've had didn't just help me close more deals. They helped me build the systems that let my team close deals while I focused on strategy and growth.

When a mentor backed me up no matter what, there was no pressure to change.

But when one challenged me, they created accountability. They set expectations. They checked in on whether I'd actually done the work.

If they told me three months ago that I needed to document my sales process, they'd ask to see it. If they said I needed to start interviewing salespeople, they'd want to know who I'd talked to.

That accountability is what separates mentors who sound helpful from mentors who actually help.

It's also what separates founders who stay stuck from founders who break through to the next level.

Cheerleaders are great when you're feeling burned out or doubting yourself.

But if you're a European B2B SaaS founder trying to hit your targets and secure your next funding round, you don't need more people telling you you're doing fine.

You need someone who will tell you the truth.

Someone who will point out that your pipeline is a mess. Someone who will push you to stop being the only person who can close deals. Someone who will help you build a repeatable, scalable go-to-market engine before it's too late.

That's the kind of mentor who actually helps you grow.

The best mentors don't just support you. They challenge you.

They push you to see the blind spots you've been ignoring. They hold you accountable for building the systems your company needs to scale. They tell you the hard truths that nobody else will.

If you're still doing all the sales yourself, if your GTM process is held together with duct tape, if you're not sure you'll hit the targets you need for Series A, you don't need a mentor who will tell you everything's fine.

You need one who will tell you what needs to change.
