About me
They will tell you...
Marianne is a rare kind of product designer. She is strategic, user-focused, and technically fluent. She collaborates seamlessly across teams, consistently delivers high-impact work, and brings clarity to complexity. I’ve hired her twice and would do so again without hesitation.
Steven Cohn
Founder & CEO of Winware.ai
Not only is she a tremendous overall human being, but she is a fantastic designer as well. She is passionate about the problems she solves, and she also works exceptionally well with others in both receiving and giving feedback.
Christopher Fernandez
Sr. Product Designer at Validately
I hired Marianne and would definitely hire her again! She is an excellent product designer who wants feedback, takes it constructively and improves quickly. She cares deeply about user research to improve her work.
Juan Lopez
VP of Product at Validately
Marianne brought her skills as a product designer and perhaps just as importantly, an energy to the team that attracted a lot of constructive customer feedback. Her approach also made team discussions collaborative and much more successful.

About me
I’m Marianne Cobbs, a French/American Senior Product Designer and Design Strategist with 10+ years of experience turning complex problems into simple, user-centered solutions.
I’ve worked across fintech, SaaS, and AI tools, from early-stage startups to growth-stage platforms.
Huge user research advocate. Clarity, impact, and collaboration drive my design process: aligning teams around real user needs, designing thoughtful systems, and building products that actually work for and not against people.
