Krisztián Stark

Founder of Sharklio and Shark Earnings

I’m Krisztián, the founder of Shark Earnings and Sharklio. Shark Earnings is a rewards site where people earn by completing offers, surveys, and tasks from offerwall partners, and building it put me on the publisher side of every problem these guides cover: integrating walls, handling postbacks and reversals, setting a fair currency rate, stopping duplicate accounts, and paying users out on time.

Sharklio grew out of that work. It is the platform I wanted as both a publisher and an advertiser: advertisers pay only for results they approve, and publishers get an offerwall that is simple to add and honest with their users. I have written more than 300 articles across the Shark Earnings Academy and the Sharklio Academy, so the lessons we learned the hard way are free for anyone to use.
