Founder & CEO, Bookyourdata

More than 20 years building the data that helps companies find the right people to talk to.

I am Baris Zeren. I founded Bookyourdata in 2015 to fix a broken model for B2B contact data: stale lists sold on subscription. Today the platform verifies every email in real time at the moment of download and serves more than 20,000 clients in 200+ countries.

About

Who is Baris Zeren?

Baris Zeren is a B2B data entrepreneur with 2 exits and more than 20 years in sales intelligence. He founded Bookyourdata in 2015 around one idea: nobody should pay a subscription for contact data that goes stale before they use it.

That idea became the pay-as-you-go model for B2B contact data. Buyers filter a pool of 500M+ profiles, pay only for the records they select, and every email address passes real-time verification at the moment of download, backed by a 97% deliverability guarantee.

Bookyourdata now serves more than 20,000 clients in over 200 countries, from solo recruiters to teams at the largest companies in tech, consulting, and finance. G2 reviewers rate it 4.9 out of 5 across 348 reviews.

Baris writes and speaks about email deliverability, data quality, and how AI changes B2B selling. He studied Material and Metallurgical Engineering at Istanbul Technical University, where an early pull toward math, data, and marketing set the direction for everything since.

Earlier ventures

Before Bookyourdata, Baris built and sold 2 companies, the foundation of 20+ years spent on one problem: connecting businesses with accurate information about the people they need to reach. His first datasets, built solo in 2004, were the world's first car and mobile phone specification databases.
