Build Your AI Chief of Staff

Samira builds products that bring people closer, not just products people use. Over 15 years, she's shipped work reaching millions: BBC iPlayer and BBC Earth, watched by 63% of the UK population weekly, and Newsela, where as Director of Product she scaled the platform to 40 million students across 90% of US schools, delivering a fourfold jump in engagement in a single month during the pandemic.

She now leads Luxo Beta, an AI product and venture studio building zero-to-one products across edtech, media, and mission-driven organisations.

Her mathematics training at Cambridge underpins every system she builds: start from first principles, not a borrowed framework.

Samira also hosts the Samira Stalks podcast, reaching 75,000 listeners across 150 countries.

Kate Marshall builds AI systems on a cybersecurity governance foundation, shaped by 18 years at SANS Institute. As a fractional CAIO, she works with HR leaders, executives, and marketing teams to translate AI from theory into day-to-day workflows and policies, with an eye on reducing risk while moving faster.

Kate is the Founder and lead AI Strategist at TheGrai (thegr.ai), partnering with executives and non-technical teams on responsible AI practices across hiring and daily productivity. Her PMP certification shapes how she works: clear builds, defined scope, and outcomes people actually use.

At SANS, she led curriculum strategy and courseware development, later serving as Director of Summits, co-chairing the AI Cybersecurity Summit and launching SANS's first AI Hackathon.
