In this episode of Scale HER Up – The Female Entrepreneur Show, I’m joined by Fiona Duguid, co-founder of Indigo Seven Ventures, Chief Information Officer at Aurora Energy Services, and the portfolio lead for Expo Design – a business creating sustainable exhibition and display solutions using engineered fibreboard made from recycled cardboard. Fiona describes how Indigo Seven Ventures invests with a focus on sustainability and “doing good in the world,” while she splits her time between fast-growth energy services and a greener alternative to traditional MDF exhibition builds.

Fiona’s career path is anything but linear. She started in medicine, switched to mechanical engineering at the University of Cape Town, worked in the nuclear industry, then pivoted into software development and technical sales in London – eventually becoming a senior account manager at Halliburton, working across Latin America, Europe and Houston before making Aberdeen home. Through each change she’s been one of very few women in the room, learning how to negotiate pay, hold her own in male-dominated spaces and back herself.

We dive deep into the gender pay gap, why women often wait to be “noticed” while men actively negotiate, and how language, body language and “knee-capping” ourselves with constant apologies holds us back. Fiona shares why coaching, mentors and honest feedback are so powerful for women – and why we have to stop assuming good work will automatically be rewarded.

From an investor’s perspective, she explains what Indigo Seven Ventures looks for in opportunities: values-aligned people, authenticity, realistic plans and a clear understanding that things will take longer and cost more than you think. We also talk about the funding gap for women-led businesses, how to aim higher when you’re raising money, and why asking for help on LinkedIn or in your network is often the most underused strategy.

Above all, this is a conversation about self-belief. Fiona is candid about underestimating herself early on, and the mindset shift that came when she realised she was “so much more able” than she’d ever given herself credit for. Her message to younger women – and to all of us – is clear: trust yourself, reach higher, and be the master of your own destiny.
