Give a massive welcome to our next LevelUp mentor – Ruben Seoane, Founding Engineer at Morpheus AI!🙌🏼

Ruben brings a massive jolt of deep-tech firepower to the Puzl community. He spends his days building at the absolute cutting edge of artificial intelligence and software architecture. Ruben is the guy who knows how to translate wild, futuristic concepts into stable, high-performing code.🚀

He’s stepping into the LevelUp program to tackle a massive theme for our current cohort: “The technical side of startups.” From choosing the right tech stack to scaling an MVP without it collapsing under pressure, Ruben is here to demystify the engineering decisions that make or break an early-stage company.

✨Watching a startup’s tech evolve is incredible and we’re thrilled to have Ruben in their corner. Stay tuned to watch their transformation unfold!

Sure, working from home has its perks (pants optional👀), but it just can’t compete with the Puzl energy...

Because coworking isn’t just about finding a desk and good Wi-Fi. It’s about connection and the unexpected magic of a living, breathing ecosystem. 🌍

🚀 Introducing LevelUp Mentor Gergana Stoichkova – Founder of Fundraise Ready and VC Compass!

Yesterday, our cohort got a front-row seat to what actually happens behind the closed doors of venture funds!
Gery joined us to deliver an incredible masterclass on Pitch Decks & VC Readiness, giving our startups the insider playbook on how to think like an investor and structure a fundable story.

Having spent years on both sides of the table—as an early-stage investor at Eleven Ventures and a mentor to hundreds of startups—Gery knows exactly what it takes to get a deal over the line. She showed our founders that building an investor-ready pitch deck requires a deep understanding of investor psychology and a compelling narrative that actively de-risks your business.

If you’re ready to stop guessing what VCs look for and build a deck that actually closes rounds, Gergana is the expert you need in your corner.

🎉Bolt Food has officially wrapped up its first week in their new 2 offices. To celebrate, we hosted one of our favourite traditions: a community breakfast to welcome the them properly.

Between decorating, settling in and making the space their own, they’re already becoming part of the neighbourhood.

These are the moments we love most—when breakfast turns into conversation, neighbours become friends, and new connections happen naturally. We’re intentional about creating a place where people don’t just come to work, but where they genuinely feel they belong.

We’re so excited to have Bolt as part of the Puzle family and can’t wait to see what’s ahead. 🧡

And if you’re looking for a workspace that feels more like a community and less like an office, our doors are always open. 🤗

This next mentor introduction hits incredibly close to home for us. Meet Verginiya—our amazing Country Manager, the heartbeat of Puzl, a true friend to our members and officially a LevelUp mentor! 💙

If you’ve ever walked through our doors, you’ve experienced Verginiya’s real superpower firsthand: her unmatched ability to connect with people, read a room and command attention with pure warmth and confidence.

In the startup world, brilliant code and data will only get you so far. If you can’t pitch your vision or lead a team, things stall.

She’s here to help you conquer public speaking anxiety, master the art of the high-stakes presentation and build the communication habits that turn skeptical investors into loyal believers.

We are so proud to have our own leading the charge. 🚀 Hit the link in our bio and apply to learn from the best today!
