For the last 6 months, I've been experimenting with building, validating and launching micro startups alone.

But I've just discovered a strategy that may increase the chances of your startup succeeding.

Reader, in this email, I'll break down why you should consider finding a co-founder for your SaaS and how you can do it.

The best way to build a SaaS

When you've read the subject of this email, you've probably thought that I'll be talking about another AI tool.

But no, in the AI era, you don't need another AI tool, but you may need another human 😁.

Yes, the best way to build a SaaS is to do it with your buddy.

For the last year, I didn't want to collaborate with anyone as I was scared to give away 50% of my startup.

I was thinking:

But then I've realised:

50% of $5k / month startup is WAY WAY WAY better than 100% of $0 / month startup.

And your chance to succeed is WAY higher if you work on something together, here's why:

• Speed doubles - you simply spend more time, so you have more resources to ship faster and try more things.
• Less likely to burn out - even when you don't feel like working, there will be a person who will push you and motivate you to keep going
• Complementary skills - an ideal combination is one technical co-founder (who can build a cool product) and a marketing co-founder (who can market your product well). That's the ideal combination, but even if your co-founder has some skills that you don't have, you can complement each other.
• Less overwhelming - building solo means you have to DO EVERYTHING and think about EVERYTHING, but when you have a co-founder, you can give away 50% of responsibilities, and it'll be way easier.

Pros of having a co-founder significantly outweigh the cons, so in most cases it's worth giving away 50% of potential income.

Plus, if you find someone with whom you vibe, it'll be SO MUCH FUN!

How to find a co-founder?

Last week, as part of my YouTube challenge, I started posting on X.​

I didn't expect to get any results from it.

BUT THIS PLATFORM JUST BLEW MY MIND.

In just 12 days, I managed to grow to 120 followers, connected with BIGGEST names in my niche (5k, 7k and even 200k followers 🤯) and found a few potential partnerships.

I could have given you a long list of places where you can find a co-founder (like meetups, your university, Facebook groups), but honestly, connecting with people on X seems to be THE BEST WAY RIGHT NOW.

So follow this simple framework, and I guarantee you'll find someone with whom you can build together:

1. Start posting on X about your startup journey (just simple updates, learnings and so on, you can literally copy my style).
2. Reply to people whom you like and to people who post in the Build In Public community for at least 30 minutes every day.
3. DM other founders who match your vibe and offer them to build something together.

That's exactly what I did for 10 days, and managed to grow to 120 followers and find a co-founder for my next SaaS idea.

Last week I was travelling, but still managed to build and launch a SaaS in 7 days, and of course, documented it in this YouTube video:

Okay, it's time to work on building some foundations for the strong start of 2026.

See you next week 👋!

Always yours,
