Deliveroo

Deliveroo posts the worst investor returns of any major delivery app, with its IPO losing over 50% of its value within the first year—proof that even dominant market share can't mask a broken business model. The platform's 2023 losses exceeded £200 million, despite charging customers an average 15% more per order than rivals like Just Eat Takeaway, which ranks five spots below at #8. Its gig-economy labor costs, ballooning to 40% of revenue, make profitability a distant dream.
