In the business of fast food, few London brands have grown as deliberately—or as effectively—as Yolk. Since starting life as a scrappy pop-up in 2014, the sandwich and coffee outfit has raised £3.6 million [$4.7 million]
in crowdfunding, opened nine high-performing stores across Central London, and is now entering a new phase of expansion that’s anything but casual; site number ten lands in Holborn mid-May, six more are planned for 2025 and, from 2026, the brand will begin its move beyond the M25.
The blueprint is ambitious—more than 100 sites, including international growth—but the philosophy hasn’t changed. “We’re ambitious, but we’re quality-first,” says founder Nick Philpot. With no central kitchen, no vacuum packs, and a still-hands-on approach to prep, Yolk’s steady climb feels like an antidote to the bloated, overextended rollouts that came before it. Add a newly launched coffee subscription, a punchy rebrand, and a team culture that runs deep, and the message is clear: Yolk is building something serious. They’re just having fun while doing it.
From strategy consulting to Steak Béarnaise
Philpot didn’t set out to build a sandwich empire. He was working in strategy consulting — “lots of spreadsheets and PowerPoint”—but couldn’t stop thinking about the disappointing state of London’s grab-and-go scene.
“Working long hours at my corporate desk, I couldn’t believe the lack of flavour and excitement in grab-and-go food,” he recalls. “On the weekends I was eating amazing meals at seated restaurants, but the convenient stuff was so pre-packaged and joyless. I felt like I was wasting precious meals. There was a gap for flavour-led, restaurant-quality food that was still quick and affordable. That was the mission.”
Food had always been a passion—“just as a greedy consumer and home cook”—and when the idea for Yolk took root, it stuck. But before locking in its central locations, Philpot took a crash course by setting Yolk up as a street food pop-up, and it turned out to be a decision that shaped how the business operates to this day.
“The first lesson was simplicity: we had to serve big surges of demand from tiny spaces, which forced us to design recipes and processes that were tight, efficient and resilient,” Philpot says. “We also learned the importance of brand. Other traders were telling their stories better than us—our visual identity was a bit of a mess at the time—and lastly, people love great sandwiches! The first time we served our Steak Béarnaise, everything changed. It just clicked.”
A brand built in stages
Yolk’s first major leap came with its 2017 rebrand—a sleek black-and-gold look that finally gave the business the polish to match its product. “It had a high-end visual presence that we’d been missing—and it gave us confidence to believe in the business,” Philpot says.
“It helped bridge the gap from scrappy street food stall to bricks-and-mortar credibility. It helped us raise our first investment, secure our first lease, and win over thousands of new customers.”
But the rebrands haven’t stopped there. This month’s opening in Holborn signals the start of what Philpot calls “Yolk 2.0”—complete with a full brand overhaul that hits all touchpoints: signage, menus, wall art, packaging, even the kitchen layout. “The old brand had served us well, but we’d outgrown it,” he explains. “It had started to feel a bit too polished and safe—it didn’t reflect the personality, flavour or energy of what we’d become.”
Customer research helped validate the need for change. “The big insight was that people loved the food, but didn’t fully understand what Yolk was all about. Some thought we were somehow corporate, which was mad to us. Others didn’t realise the food was made fresh in-house. That gave us the nudge to be much clearer, bolder and more joyful in how we communicate.”
The tagline? Good Bites Only. “It’s a promise and a mindset,” says Philpot. “Every bite should deliver joy and flavour—no filler. But it’s also how we approach everything: food, design, hiring, culture. If it’s not thoughtful, high quality, and made with purpose, it doesn’t make the cut.”
Fresh, always
One of Yolk’s key operational choices has remained surprisingly traditional: no central kitchen. Everything is prepped fresh on-site. “Firstly and most importantly, we think food just tastes better when it’s made fresh, from scratch, in-house,” says Philpot. “Secondly, it’s cultural—we want our teams to feel connected to what they’re making. That’s hard to do if you’re just opening vac-packed bags from a central kitchen. And thirdly, it works for us commercially: we have teams on-site throughout the day, and using quieter periods for prep makes sense.”
The store itself also plays a key role in how customers engage with the brand—especially now, as Holborn will be the company’s first full Yolk 2.0 site. The kitchen is more open, the branding is more expressive, and they’ve pushed operational flow to new heights.
Still, for Philpot, it’s not just about function, but about hospitality. “I think what’s so nice about hospitality is that it’s tangible—it’s a physical product and you experience it in a sensory way. People get to feel what Yolk is about: the busy kitchen, the smell of bacon cooking, the sound of milk steaming.”
Growth, with guardrails
Yolk’s latest £650,000 [$862,000] raise, completed in late 2024, was a big coup—funding Holborn’s build-out, expanding the team, and giving the brand room to grow without compromise, but Philpot hasn’t approached it recklessly. “We’ve seen so many brands overextend themselves with crazy rollouts,” he says. “We now feel confident opening 5–6 locations a year, but that’s only possible because of the foundations we’ve built.”
There’s a larger raise underway now, designed to support long-term scale, with plans for around 50 UK locations and early international activity on the horizon. “We’re also thinking about how to tailor the format for different settings—neighbourhood high streets, transport hubs—while staying true to our quality and identity.”
And while some brands have shifted their focus to delivery, Yolk is still betting on bricks and mortar. “Delivery is growing and we’re glad to be on those platforms, but we never want to become a ghost brand. We believe in real spaces that can become a part of people’s everyday.”
What success looks like now
For Philpot, growth only works if the standards hold — not just in the food, but in the people behind it. “My role has changed massively and I’m still learning every day,” he says. “In the early days I wore a lot of hats, and some fitted better than others. Now we have a brilliant team—people who are much better at their jobs than I ever was—and my role is to support them, while keeping an eye on the big picture and pushing us forward.”
And while he may be thinking big-picture day to day, Philpot admits he’ll always have one eye on the sandwich board. “The Steak Béarnaise is my desert island sandwich,” he says. “We haven’t changed it since we first served it from our pop-up gazebo, and I think it still holds up. One I’d love to crack is a fried chicken sandwich—spicy, crunchy, moreish. We don’t have deep-fat fryers, though, so we’d need to get creative. Air fryers maybe…”
Call it scaling. Call it strategy. At Yolk, it’s still just good bites only.
