Christina Nielsen
AI Consultant Manager
Christina leads AI strategy and delivery at re:ampd. She holds a business degree in data analytics, is a registered Claude Partner, and is currently working toward Claude Certified Architect status. Her biggest strength is pattern recognition, which is what pulled her toward AI in the first place — getting into the technical detail of how these systems actually work, then simplifying that down into something teachable, practical, and commercially useful for business.
Before AI became the focus, Christina built her career across marketing, events, and hospitality — an experience that still drives how she works today, keeping people at the centre and caring as much about how things are taught as what's taught.
Christina is passionate about leadership, entrepreneurship, and collaboration, and loves helping ideas come to life through creativity and shared thinking. Outside of work, she builds coded creative applications for friends and family and paints — so while she's highly technical, she's just as much a creative and a people person. She thrives at the intersection of the two, using AI as a tool for genuine human ingenuity, not a replacement for it.
Marisa Fong
Founder
Marisa is the founder of re:ampd and a business coach, investor, and commercial strategist for women business owners. She co-founded Madison Group and exited in a record-setting eight-figure sale, and now brings that operator's lens to everything we teach.
Her work sits at the intersection of commercial strategy and lived experience. She built re:ampd after noticing high-performing women were not lacking capability, they were lacking structured commercial support at the level they were operating. In the room, she keeps things direct, practical, and grounded in what actually moves a business.
Tessa Crawford
Head of Marketing and Growth
Tessa leads growth and marketing at re:ampd. She spends her days building the systems that drive a working business: CRM integration, automation, web development, paid media campaigns and analytics that tie it all back to revenue. She works in this every day.
She brings over 12 years in digital marketing across Shanghai, London, and Auckland, including global agency experience and eight-figure media budgets. She holds a Bachelor of Commerce majoring in Marketing Management, and her agency-side work means she has supported businesses across a wide range of verticals, so she understands business under real pressure and knows what actually moves the numbers.
Tessa's career has centred on working with and for women. Seeing women succeed is what drives her, and it is why her approach is built around meeting people where they are: no jargon, no hustle, just clear steps and measurable results.
Hannah Twiselton
General Manager
Hannah is General Manager at re:ampd, where she manages people, quality, and performance while driving operations and strategy across the business. She focuses on how AI and agentic tools can bring more creativity, organisation, and efficiency to marketing and reporting - helping the team work smarter, not harder. She holds a business degree in Marketing and Entrepreneurship from the University of Auckland, with overseas experience at the University of British Columbia in Vancouver.
What she's really passionate about is turning strategy into systems - building the structure and reporting that let a team move faster and stay creative at the same time. Outside of work, she's into photography, videography, and staying active and social, whether that's skiing or travelling.
