Oh, that’s pretty cool. Still not a fan.

Founders: what’s one thing you believed about your product before launching that your users proved completely wrong?

[Nathaniel Greef @nategreef]

Every person who tests Twirl reveals something we couldn’t have learned by building in isolation.

Beta isn’t just about finding bugs. It’s about learning what users actually value before going live.

[Nathaniel Greef @nategreef]

Building a startup is basically solving one problem, celebrating for five minutes, then discovering three more. Somehow, you still wake up excited to do it again.

Consistency isn’t a straight line. It’s full of wins, setbacks, momentum and doubt. The goal isn’t to feel motivated every day, it’s to keep building through all of it. That’s the founder journey.

@Kadotttt Internet. Not even lying.

[Nathaniel Greef @nategreef]

@Niakx_ Exactly. That’s been one of our biggest beta lessons, if the value isn’t obvious within seconds, every detail after that has to work harder. We’re tightening the message alongside the product.

[Nathaniel Greef @nategreef]

Halfway through the week.

Building a startup is a constant cycle of ship → test → listen → iterate.

We’re deep in beta feedback with Twirl right now, tightening the product one update at a time.

Still a lot of work to do. That’s the fun part.

[Nathaniel Greef @nategreef]

If you’re building a product right now, what’s been the hardest part: building it, finding your first users or knowing which feedback to act on?

The Twirl beta is going well 🌀

Users are testing, launching markets and helping us improve the experience with every round of feedback.

We’re preparing to go live soon. Stay close.

[Twirl @Twirlmarkets]

The Twirl beta is going well. We’re learning from every test, fixing what matters and sharpening the experience.

Next stop: going live. Soon. 🌀

Does anyone here genuinely know how to build and grow an active Telegram community?

Not vanity numbers a real, engaged audience. We’d love to connect with people who’ve done it successfully. Drop a reply or DM me 🤝

The hype around Jev is interesting.

AI doesn’t always need to generate paragraphs. Sometimes it just needs to make a fast, structured decision with an honest probability.

For prediction markets, that opens up some serious possibilities. Who’s testing it?
