Cem Hurturk
I'm an entrepreneur and founder with a passion for building software solutions that solve real-world problems. I've been shipping software since 1999, and along the way founded and co-founded multiple successful companies.
My journey began with a simple idea: to create tools that make digital marketing more accessible and effective. This led to the creation of several email marketing solutions that are now used by businesses worldwide.
Beyond business, I'm passionate about sharing my experiences and insights through writing. Every week, I publish articles about entrepreneurship, business strategy, personal growth, and life lessons.
My entrepreneurial journey
Co-founder at 50SAAS LLC
As co-founder of 50SAAS LLC, I've helped build and grow multiple successful products in the email marketing space, including Octeth, Sendloop, and Cleanify.io.
Founder of KAYRA LLC
KAYRA LLC is my online portfolio company that houses several SaaS products including TraceRank.com, LaunchMailbox.com, QuickTests.Email, ClickMonk.co, Helpmonk.com, and ContactWidget.com.
Values & philosophy
I believe in building sustainable businesses that provide real value to customers. My approach focuses on creating quality products with excellent customer support rather than chasing rapid growth at all costs.
Through my weekly writing, I share the lessons I've learned along the way, hoping to inspire and guide other entrepreneurs on their own journeys.
