Your job as a founder is to be the best filter

When you’re building something, everyone has an opinion.

You’ll get advice from mentors, investors, friends, Twitter threads, Substack newsletters, strangers on the internet, your old boss, your mum’s friend’s cousin who once worked at a startup - and, of course, that guy you met once at a co-working space who’s now in your DMs with “just a thought.”

Some of it is thoughtful. Some of it’s total nonsense. Some of it sounds smart on the surface but leaves you spiralling in a pit of self-doubt, suddenly questioning whether you’re doing everything wrong because someone else said “have you thought about B2B pivot?” with enough confidence to rattle you.

It’s a lot. And it’s constant.

One minute you’re feeling clear, focused, like you’ve finally cracked it - and the next, a well-meaning comment derails your momentum completely. You find yourself rewriting your pitch deck, rethinking your pricing model, or Googling ‘should I scrap my entire business and become a fintech founder instead?’

Because when the input gets loud, your internal voice can get quiet.

And that’s where it gets dangerous - when you start thinking your job is to crowdsource your next move instead of decide it.

But here’s the truth: the better you get at filtering, the better you get at leading.

You don’t need to action every bit of advice you hear.

You don’t need to pivot because someone with a fancy job title raised an eyebrow at your idea.

You don’t need to replicate someone else’s model just because it worked for them.

Your job is not to be a sponge. Your job is to be a sieve.

Keep hold of the stuff that sharpens your thinking - the ideas that stretch you, challenge you, clarify your direction. Let everything else slide past without sticking.

Make decisions from a place of clarity, not comparison.

Because being a founder isn’t about having all the answers - it’s about knowing which noise to tune out so you can hear your own thinking again.

Don’t forget that the only thing that really matters is customer behaviour - so turn the volume up on that!

You just need to get quiet enough - and brave enough - to actually listen.

Founder cheat sheet

Here’s how to build your filter muscle - so you don’t drown in unsolicited opinions.

Start with your own lens

Before you ask for feedback, tune in to your own instinct. Write down what you actually think before you invite anyone else in. That way, you can spot when feedback adds value - or when it’s just pulling you off track.

Turn the volume up on customer behaviour

Forget hot takes and hypotheticals. The clearest feedback you’ll ever get is what your customer does (or doesn’t do). Are they clicking, buying, signing up, sticking around, telling their friends? That’s your most reliable data point. Build from that, not just opinions.

 Create your trusted filter panel

Have a small handful of people whose feedback you actually want. People who understand your context, your stage, your goals - and aren’t just projecting their own agenda. Everyone else? Smile politely and move on.

 Remember: advice is data, not gospel

Treat every bit of advice like a data point, not a directive. Useful to consider - but not something you have to implement blindly. Your job is to weigh it up against what you know, not defer your decisions to someone else’s confidence.
