London Demo Day 2025 showcased the diversity and brilliance of innovation emerging from our universities. All 20 ventures are tackling real-world problems with quality solutions. There really is no better place than a university to support the ideas and positivity that our students and alumni bring to the world. Universities may be competitive, but this event shows us the impact of collaboration. I am so proud of the four ventures that represented King’s and can’t wait to see what they do next.

London Demo Day 2025 spotlights King's entrepreneurs
Four entrepreneurs from King’s College London pitch their ventures to an audience of investors, alongside 16 other start-ups from London’s top universities.
London Demo Day is an annual event inviting investors to see the best and brightest innovations coming from UCL, Imperial College London, the London School of Economics (LSE) and King’s College London. This year, Queen Mary University of London joined the collaboration for the first time.
Hosted at UCL’s Institute of Education, the 20 entrepreneurs pitched to an audience of over 700 guests, including investors, partners, students and alumni, each hoping to raise between £100,000 and £2 million.
The ventures, all developed by current students or recent graduates, from the five universities, spanned diverse industries including health, digital, finance, consumer and environment.
The four ventures representing King’s were:
CarbonTag
Smart technology that taps a million-point database to deliver instant assessments with transparent sources, reliability scores, and powerful benchmarking, giving food brands the verified green claims that now drive 56% of all industry growth.
Co-founder: Leonardo Vizioli (BSc Philosophy, Politics and Economics alumnus)
Hijack Bio
Hijacking gut bacteria to make diabetes treatment obsolete.
Co-founder: Salpie Nowinski (PhD Cancer Bioinformatics)
Mozart AI
A music creation platform with AI co-production, built by musicians for musicians. Empowering every music creator with complete creative control and powerful AI assistance, enabling them to make great music, faster.
Co-founder: Sundar Arvind (BSc Computer Science alumnus)
Superfanbase
Enabling creators and creatives to raise equity-based investment from their fans.
Founder: Hannah Elsy (BA English Language & Literature alumna)
All four pitching ventures were previously part of King’s Start-up Accelerator, a 12-month programme supporting King’s entrepreneurs to grow their venture, develop as a founder and supercharge their network. Participants access a thriving community, deep dive workshops led by industry experts, 1:1 mentoring and coaching, office space in our central London co-working space and dedicated fundraising support.
London Demo Day is one of the biggest events in the university’s calendars. Since 2019, 105 innovative teams have taken to the stage as part of the annual event. To date, they have collectively raised over £121 million and employ 578 people.
London Demo Day will return in 2026 and will be hosted by Imperial College London.
