Tassia O'Callaghan is a content writer and with over a decade of experience helping brands build their blogs and blog content.
She's spent much of her career working with small businesses and startups, and that passion for small business sits at the heart of how she approaches writing about AI and workplace tools. She knows firsthand how much time founders and small teams lose to email and admin, and how little margin they have for it. At Fyxer, she writes about AI, email management, and virtual meetings with that audience front of mind: People who need tools that actually work, without the overhead.
Tassia is an advocate for realistic sustainable living, supporting small businesses, and equity across different backgrounds. These values shape how she approaches every piece she writes.
