Why Young Founders Are Thriving in the AI Era — And the Challenges They Face

A new generation of entrepreneurs in their early 20s is rapidly reshaping the startup landscape, driven by fluency in artificial intelligence and the confidence to build companies before gaining long-term corporate experience. Among them are Arnau Ayerbe, Pablo Jiménez de Parga Ramos and Bergen Merey, the 24-year-old founders of Throxy, a London-based company developing AI agents for sales teams. Despite landing coveted graduate roles — including Ayerbe’s position as an AI engineer at JPMorgan — all three felt constrained by traditional corporate paths and joined forces to launch their own venture in 2023.

Their leap into entrepreneurship has paid off: Throxy has already raised nearly £5m across two funding rounds and generated £1.2m in annual sales. They are part of a larger trend in the UK, where 62% of Gen Z say they want to start their own business, according to Enterprise Nation. Data from the British Business Bank shows Start Up Loans awarded to Gen Z founders have doubled over the past five years.

But success has come with intense pressure. Ramos describes a demanding “9–9–6” culture — 9am to 9pm, six days a week — while Ayerbe admits he might not have started the company had he known how difficult the journey would be. Still, the trio credit their comfort with AI as a major advantage. Ayerbe says early access to advanced models, including early versions of ChatGPT, convinced him AI was destined to transform work and create huge opportunities for young innovators.

Their story reflects a broader shift. Research by the investment network Antler shows that the average age of founders behind AI unicorns — companies worth over $1bn — has fallen from 40 in 2020 to 29 in 2024, underscoring the momentum behind younger entrepreneurs.

Yet age can also be a barrier. Rosie Skuse, founder of Molto Music Group, says she was often mistaken for an assistant when she launched her company at 22. Some clients refused to shake her hand until they realized she was the CEO. Today, at 29, she leads a thriving music and entertainment agency with high-end clients including The Dorchester, The Savoy, Soho House and Raffles, and reported £1.6m turnover in 2025. She says youth can be a “secret weapon” — surprising people and forcing them to pay attention.

But experienced founders caution that rapid growth alone isn’t enough. Serial entrepreneur Lee Broders warns that “speed can hide fragile foundations,” noting that a business must be sustainable, not just flashy. Meanwhile, Sarah Skelton, co-founder of recruitment firm Flourish, argues that young founders sometimes miss out on critical management skills typically developed in traditional jobs. Lacking leadership experience, she says, can make scaling harder later on.

Still, for many young entrepreneurs, the mix of ambition, AI fluency and a willingness to learn through trial and error continues to drive remarkable success. As startups like Throxy rise, they highlight a generational shift toward faster innovation, new work cultures and a belief that the future belongs to those ready to build it early.
