Key takeaways:
- Successful food startups begin by solving a genuine problem, but long-term success depends on adapting when product development, packaging and commercial realities don’t go according to plan.
- Startup competitions, accelerators and mentoring programmes can offer far more value through industry feedback, networks and validation than through prizes alone.
- Sustainability may attract initial interest, but repeat purchases are ultimately driven by products that deliver on taste, nutrition and value.
Universities have become one of the food industry’s most productive innovation hubs. Every year, students develop products designed to tackle everything from food waste and sugar reduction to functional nutrition, yet relatively few of those ideas survive beyond graduation. It’s rarely because the products lack potential. More often, the realities of manufacturing, regulation, product development, supply chains and commercialisation prove considerably more demanding than the original business plan ever suggested.
That raises an important question for aspiring entrepreneurs. What actually separates the handful of student startups that become genuine businesses from the countless ideas that quietly disappear once the coursework has been marked?
Four students from Harper Adams University in Shropshire believe they’ve begun to find the answer. What started in late 2025 as part of the university’s Young Enterprise programme has evolved into Riff, a registered snack business that will represent the UK at the Young Enterprise European Finals in Athens, Greece, this July. The company is still at the beginning of its journey, but its founders have already encountered many of the challenges that confront far more established food manufacturers.
Co-founder Lucie Campbell doesn’t romanticise the startup journey. Failed formulations, packaging redesigns, company registration delays and the realities of building a supply chain around rescued ingredients have all forced the team to rethink its original assumptions about what it takes to build a successful food business.
Start with the problem, not the product

Like many startups, Riff began with a simple observation rather than a carefully researched market opportunity.
“We noticed an enormous surplus of perfectly good bananas constantly left behind in our community fridge,” Campbell explains. “When we started the Young Enterprise programme, we asked ourselves, ‘What can we do with all this surplus fruit?’”
At first glance, the idea sounds straightforward, but the founders quickly realised they had stumbled across a much larger issue. According to climate action NGO WRAP, around 10.7 million tonnes of food are wasted every year across the UK after the farm gate, while globally around one-third of all food produced is either lost or wasted. Campbell says discovering that around 71% of food surplus remains perfectly edible convinced the team they were looking at a genuine commercial opportunity rather than simply an environmental concern.
However, many startups become so focused on developing a product that they lose sight of the problem they’re trying to solve. Riff approached the challenge from the opposite direction, asking how surplus food could be given a commercial purpose before developing a snack bar around the answer.
They eventually developed a range of minimally processed bars made using rescued fruit, freeze-dried ingredients and overlooked components such as cocoa husks and banana peel. Delivering around 10g of protein and 10g of fibre per bar, the products reflect growing consumer interest in functional nutrition, but Campbell says the business only began to feel real after receiving honest feedback from experienced industry professionals.
“The turning point came during our journey to the UK Young Enterprise Final,” she says. “Presenting our concept and speaking directly with industry professionals changed everything. They told us flat out that this shouldn’t just remain a competition project – Riff had the legs to become a viable commercial brand. That was the moment we realised Riff needed to become a real business.”
The judges’ feedback may have provided the confidence to continue, but Campbell believes the programme itself delivered something even more valuable. “Riff simply wouldn’t exist without the Young Enterprise programme. It provided the initial framework, a massive safety net and an invaluable network of mentors. It gives young entrepreneurs the backing to try something ambitious without feeling entirely alone, while still holding you completely accountable.”
That experience also changed Campbell’s view of startup competitions. Rather than focusing on winning, she believes founders should treat them as opportunities to build relationships, seek advice and expose their business to people capable of opening doors.
“Don’t view it just as a competition to win. View it as a platform for exposure. Tap into every mentor, ask for help constantly and use the stage to get your brand in front of industry eyes you’d otherwise never have access to.”
Honest, experienced feedback is often far harder for startups to find than funding, which is why accelerators, incubators and startup programmes can prove invaluable long after the pitch has finished or the prizes have been awarded.
When things go wrong

Every entrepreneur expects challenges, but few anticipate quite how quickly they arrive.
Riff’s first major lesson came when laboratory testing showed the team’s carefully developed recipes failed to deliver the nutritional profile they had been aiming for. Months of product development suddenly had to be revisited.
“We had to reformulate from scratch,” says Campbell. “While frustrating, rewriting those recipes forced us to truly master our product formulation, resulting in a significantly better, healthier final snack.”
The setbacks didn’t stop there. A delay at Companies House temporarily prevented the business from progressing supplier agreements and packaging, while an entire packaging run had to be redesigned after the wrong specification was identified before printing.
Many founders would have interpreted those problems as warning signs. Campbell, however, believes they became some of the company’s greatest strengths because every obstacle forced the team to understand the business in greater detail.
“Just when you think everything is running smoothly, something will go wrong. It’s the nature of the beast. The trick is not to let it ruin your momentum. Take it as it comes, fix the problem and look for the hidden opportunities because sometimes the best breakthroughs come from mistakes.”
That philosophy extends beyond product development and into team dynamics.
“Leave your ego at the door and know your team,” Campbell advises. “Be brutally honest with yourselves and each other. When something goes wrong, be quick to put your hand up, take accountability and pivot.”
Her final piece of advice reflects another mistake many startups make: trying to appeal to everyone usually means appealing to no one. “You cannot target everyone. We received invaluable advice early on that you need to know your customer in a borderline creepy way – when they eat, sleep, go to the gym, their hobbies, likes and dislikes.”
Large food manufacturers often spend millions trying to understand consumer behaviour through research programmes, data analysis and shopper insights. Startups rarely have those resources, but they can compensate by staying much closer to their target audience and adapting far more quickly as consumer needs evolve.
Beyond the sustainability story

Food waste and upcycled ingredients have become increasingly familiar themes across the industry, making sustainability alone a difficult way to stand out. Campbell says that reality shaped the way Riff positioned itself from the outset because the founders recognised that environmental credentials might encourage consumers to try a product once, but they are unlikely to drive repeat purchases on their own.
“We don’t treat ‘wonky’ or upcycled as our sole identity,” she says. “We treat it as an integrated part of a much bigger value proposition.”
That proposition combines sustainability through rescued ingredients and compostable packaging with nutrition and flavour. In fact, in Campbell’s view, the rescued ingredients aren’t simply preventing waste; they make the bars better. “Overripe bananas are naturally sweeter, meaning we don’t need artificial additives, while cocoa husks add incredible depth of flavour. Sourcing surplus berries also allows us to include more real fruit at a competitive price point, passing that value directly to the consumer.”
The emphasis on fibre also aligns with one of the fastest-growing trends in food and nutrition. While protein has dominated snack innovation for much of the past decade, growing consumer interest in gut health and the viral rise of ‘fibremaxxing’ are encouraging producers to rethink how fibre can become a stronger commercial advantage. Campbell believes that shift presents a significant opportunity for brands prepared to move beyond protein-centric positioning while also challenging assumptions about surplus ingredients.
“We want to position Riff at the absolute forefront of the ongoing gut health and fibre revolution. As consumers become more educated on gut health, we want Riff to be the go-to high-fibre option they trust.”
The founders’ ambition is to establish Riff as a challenger brand sitting alongside established names on supermarket shelves within the next three to five years, but Campbell knows the biggest challenge will be scaling a business built around ingredients whose availability naturally fluctuates.
“Nature isn’t perfect. Instead of fighting those irregularities, we’ve embraced them, proving that whilst our ingredients might look a tad wonky, the quality and taste remain flawless.”
Those early challenges may ultimately prove to be the easy part. The next test is scaling the business without losing the agility and purpose that helped create it in the first place.
Most university assignments end with a presentation, a grade and little reason to revisit the project once the semester finishes. Riff has taken a different route. Its story isn’t really about rescued bananas or snack bars but about what happens when an idea collides with commercial reality. The founders discovered that launching a food business means constantly adapting, questioning assumptions and solving problems they never anticipated. Those may prove to be the most valuable lessons of all.
