Rosie Hoggmascall is a growth consultant and product strategist who has spent her career helping early-stage startups grow. Her breadth of experience across activation, retention, and user research gives her a grounded, analytical perspective on how people actually use technology.
At Fyxer, Rosie is Head of Product and UX, working across the full product lifecycle from activation and retention through to product-led sales, research, and strategy. She also writes about email productivity, AI tools, and how people work, bringing the same curiosity she applies to dissecting great products every week.
Outside of Fyxer, she runs Growth Dives, a weekly newsletter where she breaks down the products of great companies through annotated, actionable breakdowns. It's built for those who learn through patterns and visuals, and want to take that inspiration back to their own teams.
Rosie is an advocate for smarter ways of working, product-led thinking, and the idea that better tools should create space for the rest of life, not just more work.
