# Maggie Armstrong > Staff / Principal Product Designer | 0→1 & Growth | Two-Sided Marketplaces | Health, Community & Trust-Driven Products Location: San Francisco, California, United States Profile: https://flows.cv/maggiearmstrong I’m a Staff / Principal Product Designer with 10+ years of experience designing two-sided marketplaces and consumer platforms that drive real-world impact. My work sits at the intersection of 0→1 product thinking, growth, and high-craft execution—helping teams turn ambiguous problem spaces into clear, shipped experiences that improve activation, engagement, and retention. Most recently, I’ve been leading design for a caregiving and health platform, where I: - Increased onboarding completion by 31%, unlocking $2M+ in revenue - Improved engagement (+35% increase in provider messaging) by building trust and redefining how we deliver personalized value - Built and scaled a design system that reduced costs by $650K annually What I’m known for: - Designing two-sided ecosystems: Balancing the needs of multiple user groups and creating meaningful value exchange between them - Turning ambiguity into strategy: Framing the right problems, defining opportunities, and aligning teams around a clear direction - Shipping and learning quickly: Using prototyping, A/B testing, and data to validate ideas and drive decisions - Raising the bar for quality: Strong interaction design, systems thinking, and attention to detail - Designing for trust and emotional context: Especially in health, caregiving, and relationship-driven products What I care about: I’m most motivated by products that sit in high-stakes, human moments—where design can help someone feel more confident asking for help, more supported navigating a challenge, and more connected to others. I believe great product design doesn’t just solve problems—it creates clarity, trust, and forward momentum. ## Work Experience ### Principal Product Designer @ Cleo Jan 2024 – Present ### Senior Product Designer @ Cleo Jan 2021 – Jan 2024 Cleo is a family benefits platform offered by major employers, helping working families thrive.
