Karolis Kosas Portfolio
Designer currently at OpenAI (formerly Stripe) whose portfolio spans consumer security (CUJO), an acquired events platform (YPlan, acquired by TimeOut Group), and an App Store-featured film app (Cinema Club).
What makes it work
A breakdown of the choices that make this portfolio stand out.
Career trajectory through recognizable acquisitions
YPlan's acquisition by TimeOut Group is a verifiable, dated business event that anchors the case study in something bigger than the design work alone.
App Store/Google Play featuring as external validation
Being featured on both platforms is a form of third-party curation validation, distinct from self-reported quality claims.
Progression from startup design work to Stripe/OpenAI
The visible arc through increasingly selective companies implicitly signals a hiring bar his work has repeatedly cleared.
What UX Designers can take from this
Specific, actionable tips to apply to your own portfolio — no generic advice.
If a company you worked at was acquired, name the acquirer and date.
App Store/platform featuring is real external curation — mention it explicitly.
When your career has moved through increasingly selective companies, let that progression be visible in how you order your work history.
