We’re excited to announce that Middleton Enterprises has backed SushiDog with an additional £1.3 million — fueling further growth across London and beyond. The investment will help to accelerate the next phase of growth as SushiDog aims to increase the rate of openings, with a view to expanding the chain to 40 sites over the next five years.

The £1.3 million investment cements a relationship that began when Middleton Enterprises led a funding round of £612,000 in 2023, followed by a direct £800,000 investment in 2024. This investment helped to finance the opening of new sites in central London, including SushiDog’s tenth, and largest store, on Warren Street, that opened in April in 2025. SushiDog has consistently delivered repeatable growth, leading to this longer-term commitment.

SushiDog’s Co-Founder, Greg Ilsen, said: “Middleton Enterprises provided the stability and finance we needed to scale quickly, to the extent that we are on track to generate over £8 million this financial year and now employ around 130 people. We’re in a good position and the latest round of funding will help us speed up our rate of growth. Middleton Enterprises have an entrepreneurial spirit and they’ve always been very supportive. When they came on board we had four sites in London, we’ve recently opened our tenth store and now we’re looking to expand nationally, perhaps even internationally further down the line”.

James Middleton, Investment Manager at Middleton Enterprises, said: “This is our third investment into SushiDog. We made the decision to invest in the business again because it has a proven rollout model, based on predictable, repeatable growth. They have constantly raised the bar, innovating and evolving with each new store, which gives us confidence in the next stage of growth that will see new sites appearing up and down the country. We have a great relationship with the founders, who know that we’re willing to invest in a longer-term project, providing the necessary finance to help them with each phase of development.”
