From leading products to leading with purpose: the 20-year product veteran building her own AI platform
Every founder story seems to start with a genius in a garage. Sadia Hamid’s starts in Sheffield, with a product leader who spent twenty years making other people’s products successful, and finally asked what it would take to build something with purpose at its core. Her own.
Sadia’s track record reads like a masterclass in scale. She has led product across telecoms, ecommerce and edtech, and in Dubai directed digital transformation for a nine-million-customer base, re-platforming more than 10,000 products and shipping machine-learning personalisation in production. An Executive MBA at London’s Bayes Business School stretched her view of what innovation looks like, from Silicon Valley to Nairobi’s Silicon Savannah to Vietnam’s rising digital economy. Most recently, at a global edtech marketplace, she took AI products from idea into production herself.
“A career I’m proud of,” she says. “And every line of it built on someone else’s roadmap.”
When her last role ended earlier this year, Sadia did what sensible people do. Polished the CV. Applied. Interviewed. One rejection called her overqualified; another said underqualified. They arrived in the same week.
“Somewhere between those two emails, something shifted. I was asking strangers for permission to do the thing I’d spent two decades doing. So I stopped asking.”
The problem that wouldn’t leave her alone
Working in edtech put Sadia close to the millions of students trying to study abroad every year. Living it taught her more. “I came to the UK as an immigrant. I know what it is to sit on the wrong side of an exam table with your next five years riding on a Saturday morning test slot. That feeling doesn’t leave you.”
Nearly all of those students pass through the same narrow gates: IELTS, TOEFL, PTE, SAT, ACT and more. The exams are hard enough; the preparation industry is harder. A question bank here, a video course there, a tutor if the family can stretch to it. Three subscriptions that don’t talk to each other, all priced as if every student carries a corporate card.
WizardTeacher is Sadia’s answer. One membership. Every major test. Expert preparation at a price students can actually pay. And because the exam is only the middle of the journey, the platform supports the whole arc, from shortlisting universities to the career on the other side.
The innovation is easiest to see up close. A student finishes a practice essay and gets it back in seconds, scored against the official marking criteria, with the exact sentences that cost them marks and what to write instead. That used to mean a trained examiner and a week’s wait, out of reach for most families. “A student in Lagos or Lahore simply couldn’t get this before,” Sadia says. “For the first time in my career, the product and the purpose are the same thing.”
Building it without being “a developer”
Here is the part people don’t believe at dinner parties: Sadia designed and built the platform herself. Claude’s API at the core, Stripe handling payments, Supabase underneath, more than a dozen services stitched together, with the AI running in a London region so student data stays in the UK. “I’m not a traditional developer. I’ve become something the job title hasn’t caught up with yet.”
The seed was small: a data scraper she coded in her previous role that collapsed an hour of manual work into ten minutes. “A modest thing. But it planted a dangerous thought. Maybe the wall between product people and builders is just a story we keep telling ourselves.”
She is refreshingly honest about AI-assisted building, in a landscape drowning in weekend-app fairy tales. “The AI writes wrong code with exactly the same confidence as right code. I’ve gone to bed defeated by a payment flow and woken at 2am knowing precisely which question I forgot to ask it.”
What carried the product over the line, she insists, wasn’t the AI but twenty years of unglamorous habits. Edge cases. Testing discipline. Data quality. Deciding what not to build. “AI has made execution astonishingly cheap. Judgement still costs what it always did.”
Her advice to anyone standing where she stood
For product leaders with an idea in a drawer, Sadia offers three thoughts:
- Your experience is the moat. “Code is cheap now. Knowing what users actually need, and spotting when the confident answer is wrong, just became the scarcest skill in the room.”
- A career pause is a decision point, not a verdict. “It forces the question most of us dodge: if you trust your product instincts, why do they only run on someone else’s roadmap?”
- Build wherever you are. “I’m doing this from Sheffield: low costs, a community that answers its emails, and a healthy distance from the noise. The ecosystem conversation rarely looks north of the M25. The building happens anyway.”
WizardTeacher launches its first phase in the coming weeks at wizardteacher.com. Sadia won’t pretend to know how the story ends, but she has a rule that carried her across: “Use AI where wrong is cheap and caught, humans where it’s expensive and quiet.”
