The thing I would tell 25-year-old me
When I started my first company, I thought advice was the answer to everything I didn't know yet.
When I started my first company, I thought advice was the answer to everything I didn't know yet.
I listened to every podcast on my commute, read every founder book I could get my hands on, and saved every LinkedIn post that promised the secret to growth, fundraising, or hiring the right people. My notes app became a graveyard of frameworks I never actually used, and my browser had 40 tabs open at all times because I was convinced the next piece of wisdom was going to be the one that changed everything.
But here's what nobody tells you when you're starting out and hungry for someone to hand you the playbook. Most advice is really just someone describing what worked for them in their specific market at their specific stage with their specific team on a specific Tuesday in 2019, and by the time it reaches you, it has been stripped of all the context that actually made it useful.
Raise fast, stay lean, hire for culture, hire for skill, niche down, stay broad, go enterprise, go self-serve. It all sounds smart when you hear it in isolation from someone you admire, but when you try to hold all of it in your head at once, you end up in a kind of paralysis where every decision feels like it might be the wrong one.
The thing I would tell 25-year-old me, if I could go back and sit her down, is pretty simple:
Stop collecting advice like Pokemon cards. Start questioning if it actually applies to you.
Who said it, what were they selling when they said it, what stage was their company at, did it work once or did it work ten times, would it still work in your market with your customers at your price point with your team of three people running on fumes?
Advice without context is just noise dressed up as wisdom, and the sooner you learn to interrogate it, the sooner you stop executing on someone else's playbook and start building your own.
The second time around, I listen to way fewer people, I ask way more questions, and I trust my own pattern recognition more than I trust a viral post from someone who raised a Series B in a zero-interest-rate environment.
Turns out that was the real lesson the whole time.

🇷🇴 The first ITBW event in Bucharest

This month, we hosted our first "In the Built World" event in Bucharest, Romania, together with INVOX Call Tracking and Digital Partners
It was a curated gathering that brought together some of the most important real estate developers in Bucharest.
