Sarah Guest is a core member of all the HeuristicDev: The Mentoring Hub teams, is Lead for its Tech Mentoring Haven program, and is an International Speaker.

As a career switcher herself, there's no-one better for you to talk to about getting involved in our Tech Mentoring Haven program: either as a mentee or a mentor.

Come talk to Sarah on our booth at South Coast Summit.

HeuristicDev: The Mentoring Hub

One connection can change everything. Start here.

HeuristicDev is a UK charitable organisation (CIO Foundation – registration pending) dedicated to promoting diversity and equality of opportunity in Digital Technology and STEM. We provide education, training, and mentoring programmes that empower people who are under-represented in tech to thrive.

Why is The Mentoring Hub needed?

As of 2025, women make up only around 26% of the UK tech workforce — meaning that for every woman in the industry, there are roughly three men. The Mentoring Hub’s services play a crucial role in changing this imbalance, supporting women and other under-represented groups to enter, progress, and flourish in their tech careers.

New Speaker Academy

Join us at our stand to learn about the New Speaker Academy — a structured programme designed to build confidence and help aspiring speakers share their voices. Participants are paired with a mentor who supports them step by step through creating sessions, crafting submissions, and presenting at lightning talks, user group events, and conferences — both online and in person. The academy also includes a comprehensive course to guide each speaker through their personal development and speaking journey.

Tech Mentoring Haven

You can also find out more about our Tech Mentoring Haven — designed to mentor career switchers moving into tech, helping them navigate change and succeed in their new roles. We’re keen to connect with career switchers to learn from your experiences and shape our programme around real journeys and needs.
