Background
About Lesley Mostello
Hi, I’m Lesley. I’m a people operations leader with 15 years of experience helping high-growth startups scale intentionally, without losing the heart of their culture. I’ve built HR functions from scratch, partnered with executives to align people strategy with business goals, and developed processes that make work better for everyone. I bring clarity, empathy, and a business mindset to the table, and I’m excited about creating cultures where employees want to stay, grow, and thrive.
