I believe the best partnerships with founders are built on trust, transparency, and shared ambition. Having worked across private equity, M&A, and high-growth companies, I bring financial discipline and a practical perspective to complex decisions. I value working alongside founders to anticipate challenges, strengthen the foundations of the business, and turn ambitious visions into enduring companies.

Great companies are built by great people, full stop. I love helping founders find, win over, and keep the ones who will define their next chapter.

Get the team right and everything else starts to fall into place.

I want founders to feel like they’ve got a real teammate on the other side, someone who actually picks up and actually follows through.

A lot of the value is in the small things: the right intro at the right moment, or one fewer thing on your plate this week. I care a lot about getting that part right.

Şafak Tüfekçi

I like getting into the substance with founders and thinking out loud until the real answer shows up.
The company is always yours, so my job is to sharpen the thinking and then get behind whatever you decide. Candor and momentum beat being right, every time.

Berkay Mollamustafaoğlu
Venture Partner, Strategy

I’ve built a company from nothing and seen it all the way through, so I know what this actually takes. That’s why I show up as an operator first.

I want to be in the details with you, thinking through the hard calls together, not handing down opinions from a distance.

Dilek Dayınlarlı
Managing Partner
Istanbul
Managing Partner at ScaleX Ventures, bringing over 13 years of venture investing experience to the firm.

I think in decades, not rounds. The founders I work with know they’ll get my honest read every time, especially when it’s the hard thing to say.

I’d rather build something real with a handful of people I believe in than chase everything that moves.
