From founding one of the first female-led unicorns in Turkey to championing a new generation of female leaders

In 2012, Hande Cilingir founded Insider with Serhat Soyoerel, Sinan Toktay, and Arda Koterin. The Turkish AI-based marketing platform enables brands to connect cross-channel data, individualize experiences, and predict future behavior.

Insider was selected by Endeavor in 2014 and has made it into our Endeavor Outliers Program multiple times, and is one of Endeavor’s fastest-growing companies globally.

“Endeavor has always been a trusted partner helping us grow in every way,” says Hande. “From opening an office in Japan or the UK to signing our first deals with the world’s top enterprise brands, from finding the right hires in a given market to finding the right mentors for our team. Endeavor always provided invaluable support globally.”

In 2016, she was named “Microsoft’s Woman Entrepreneur of the Year,” and today, Insider helps more than 1,000 global brands in 26 countries manage their multi-channel marketing processes, including Singapore Airlines, Samsung, Uniqlo, and Estée Lauder, among others.

In March of 2022, Insider became one of the first female-founded and female-led SaaS unicorns in the world.

Their Multiplier Effect

In addition to inspiring women entrepreneurs, Hande also employs them in leadership roles. Half of Insider’s top executives are women. On top of that, nearly three dozen startups have been founded by former Insider employees.

”Endeavor’s role in the ecosystem is unprecedented,” explains Hande. “We will always work hard to pay it forward. We will prove to the world that legendary product companies can be created outside of Silicon Valley. We will inspire more entrepreneurs to start their own companies and change the destiny of their countries and communities.”
