Safe failures, scaling in different markets & "aha" moments

I’ve just published a new episode of the From 0 to 100M podcast, and I am particularly excited about this one. It features an amazing entrepreneur who’s also a dear friend of mine - Gabriela Constantinescu, Co-founder and & CPO at Chambr.

Chamber is a Techstars-backed AI Sales Roleplay and Coaching Platform that helps teams ramp twice as fast, close more deals, and build real-world selling confidence. 

In this conversation, we dive into the learning experiences that shaped Chambr’s founders and the pivotal “aha” moments that set them on their entrepreneurial path.

We explore the origins of Chambr, the core beliefs behind the product, and how they’ve intentionally designed a tech solution that enhances, not replaces, the human element in training. From rapid prototyping to expanding from Europe to the U.S., we talk about the cultural and operational differences of building in two distinct markets.

You’ll also hear their take on decision-making under uncertainty, what to do when things don’t go as planned, and the philosophy of “safe failure”.

Finally, we explore AI’s growing role in learning: the benefits, the risks, and what they’d build if they had unlimited AI capacity. And, of course, we talk about how they balance performance with play along the way.

If you’re curious about the future of learning, founder journeys, or building products that truly empower people, this episode is for you.

Together with Relm, we are launching In The Built World: a curated community for the founders, operators, and investors shaping the next decade of real estate and PropTech.

It’s the group that will help define the culture, the conversations, and the collaborations that will follow. And because of that, Relm x VAUNT are keeping the list curated.

If you want in, this is the moment. When the first batch opens, you will get access to exclusive things. Sign up now to be one of the first builders in the room: https://inthebuiltworld.com/join-us
