Born from Real Experience, Validated by Real Feedback

Years of market research and countless founder conversations revealed the same pattern: great ideas were failing not from lack of effort, but from lack of validation. Double-Check was created to change that

Iryna Iakhno

With over 15 years of experience as a marketing and venture manager, Iryna has built her reputation by helping founders navigate the uncertain path from start to market fit, working directly with startups across Europe and Asia since 2017. She saw the pattern clearly: entrepreneurs were spending months (and often their entire runway) building solutions without truly validating demand. Expert feedback was either too expensive, too slow, or filtered through biased networks. Double-Check.io is Iryna's solution to this challenge - a platform that democratizes access to unbiased validation, putting real feedback in founders' hands in hours, not months.
