Lessons from Building a Fintech in Romania | Sebastian Piu, 123credit.ro
n this episode, I sit down with Sebastian Piu, Co-Founder and Managing Partner of 123credit.ro (http://123credit.ro), a digital credit brokerage platform that's reshaping how individuals and companies access financing in Romania.
Sebastian shares the raw story of building a fintech from scratch during the pandemic — from a soft launch that overwhelmed a 4-person team with 150 applications in one afternoon, to financing over €205 million in credits by 2025.
We talk about the mistakes he made early on, why having a great product isn't enough, how trust is actual infrastructure in fintech (not just a marketing label), the burnout he nearly experienced, and why founders should never try to be the smartest person in the room.
Whether you're building a fintech, scaling a startup, or just thinking about making the leap into entrepreneurship — this conversation is packed with hard-won lessons.
Topics we cover:
→ How 123credit.ro (http://123credit.ro) was born during the pandemic and the recent launch of 123leasing.ro (http://123leasing.ro)
→ Why distribution outlasts the product
→ The difference between generating leads vs. generating clients
→ Bootstrapping, raising a €3M round, and the financial sacrifices of founding
→ Near-burnout and the discipline that pulled him through
→ Why culture alignment transformed their dev team's output
→ His advice to anyone in their 20s thinking about starting a business

Trust, Data, and Finding Joy in the Startup Grind with Mircea Serediuc - CPO @ Narrio
In this episode of Lesson Learned, I sit down with Mircea Serediuc, Co-founder and CPO at Narrio.app, to talk about what happens when your "hallucinations" meet the reality of the market.
Mircea and I dive deep into why you should actually choose your team before your idea. We explore the pivot from employee advocacy to fixing the "bad data" problem that keeps revenue leaders up at night, and why most CRMs are failing to give real insights.
We also get real about the "struggling moments"—the anxiety a sales leader feels before a board meeting and why people don't buy features, they buy the emotion of being in control. From rejecting the wrong clients to finding the "joy" in the middle of the startup grind, this conversation is a reminder that we rise by lifting others.
In this episode, we discuss:
The Power of the Pivot: Moving from sales enablement to the semantic layer of data.
Outbound as a "Quest": Why I’m testing small, hyper-personalized campaigns instead of "spray and pray."
The Emotional Job: How Narrio helps leaders take decisions without chasing their teams for info.
Startup Survival: Dealing with the fear of failure and the importance of a "safety net" made of people, not just money.
Whether you're a lone wolf trying to become part of a pack or a founder struggling to find the joy in the chaos, Mircea’s insights on Jobs to be Done will change how you look at your product.

We dive deep into why high-quality, structured data is the only way to actually make the "AI hype" work for your marketing. Julia also gets real about the "lessons" (not mistakes!) they learned along the way. like the struggle of transitioning from a lifetime pricing model to subscriptions and the weight of supporting "grandfathered" users for years.

Go-to-Market Evolution: How they moved from organic forum growth to a powerhouse strategy focused on partnerships and affiliate referrals.
The "Hidden" Acquisition Channels: Why Julia regrets not starting educational content from day one and how content compounds over time.

Actionable Lessons: Why you need to get your face out from behind the logo, talk to your customers more than you think is necessary, and turn your best users into your best salespeople.
