I bring people, ideas and technology together – so that potential turns into real change.

I'm Lefti – entrepreneur, advisor and bridge-builder between corporates and startups, tech and people, idea and execution. I support companies, founders and teams in spotting new opportunities, putting ideas into motion and actively shaping what comes next.

Mindset

Change begins with people.

I believe in ideas that get executed. In technology that serves people. In learning that transforms organisations. And in people who often carry far more potential than they themselves can see.

I'm drawn to the spaces in between: between corporate and startup, strategy and execution, technology and humanity, experience and curiosity. That's where the most interesting change tends to happen.

Experience

Experience from several worlds.

I bring experience from international corporations, my own startup ventures and investments, digital transformation, marketing, business development, learning & development and AI-supported knowledge sharing. My strength lies in connecting different perspectives: thinking strategically, acting entrepreneurially and getting people excited about new paths.

Corporate & Brand Experience

International marketing, brand and communications experience at Mercedes-Benz, plus digital brand leadership at s.Oliver.

Startup & 0-to-1

Startup investments and hands-on founder experience with Smoope – from idea, product and go-to-market through fundraising and growth all the way to the sale to Serviceware SE.

Digital Transformation & AI

Advisory around digital transformation, social media, AI potential and the human side of technology.

Business Development & Sales

As interim manager and as co-founder I have repeatedly brought new products and services to market, built sales processes and multiplied revenue.

Collaboration

Where I can think, structure and move things forward.

Some situations don't need yet another standard process – they need honest sparring, the right questions, strategic context and the next concrete step. That's exactly what I love working on.

Personal

A little more than a CV.

I'm shaped by German and Greek roots, born in Ostfildern, with family ties to the sunny island of Rhodes and a deep curiosity about people, ideas and change. I've worked in corporates, founded startups, stood on stages, lived through hypes, processed setbacks, searched for new paths – and learned over and over again: in the end it's not just about technology, strategy or growth. It's about people and personalities.

Let's find out whether and how I can help.

If you're working on an idea, a project, a challenge or a possible collaboration, I'd love to hear from you.
