E-commerce companies are amongst the fastest-growing businesses in the world, with several of the UK’s unicorn companies operating in the e-commerce space. Whilst retail e-commerce sales are still on the up, recent reports suggest that growth in the UK e-commerce sector is slowing this year. And globally, e-commerce giants like Shopify and Amazon are also facing setbacks.
But what exactly is e-commerce? Read on to find out more about the UK’s e-commerce market, and discover the 15 top e-commerce companies to watch in 2022.
What is e-commerce?
E-commerce describes the exchange of money and data for commercial transactions over the internet. The term “e-commerce” is frequently used to refer to the online sale of physical goods, but it can also refer to the sale of services and other kinds of online business transactions.
Biggest players in the e-commerce market
Amazon and Alibaba Group are two of the largest e-commerce companies today, and among the 10 most valuable brands across the globe. The world’s largest company, Walmart, is also investing in the e-commerce space; despite its huge number of brick and mortar stores, the company’s e-commerce stores now pose a threat even to Amazon.
The convenience of online shopping compared to in-store purchases has revolutionised the retail sector. And with the development of payment gateways that support secure debit or credit card payments and online wallets like PayPal, the e-commerce industry has boomed. Now, it seems the latest trend in this ever-evolving sector is live e-commerce sales, such as on social media platforms like TikTok.
B2C e-commerce companies
Led by the likes of Amazon and JD.com (Jingdong), business-to-consumer or B2C e-commerce companies operate online storefronts to sell products to consumers. This can take the form of direct sellers, like retailer ASOS, specialised e-commerce websites, such as electronics retailer Rakuten, or fee-based sites, such as Netflix and Prime Video which offer online streaming services.
B2B e-commerce companies
Business-to-business (B2B) e-commerce companies are typically wholesalers, retailers or manufacturers that transact with other businesses online. B2B e-commerce exists across the supply chain, including services marketplaces, goods marketplaces like wholesaler Alibaba, or equipment and raw materials suppliers like Knowde.
C2C e-commerce companies
Consumer-to-consumer (C2C) e-commerce has grown exponentially during the COVID-19 pandemic. C2C e-commerce websites act as a third-party platform for consumers selling to other consumers. Initially popularised by eBay, other tech giants like Amazon and Facebook have now produced their own C2C marketplaces in its image. Another prominent C2C e-commerce platform is Etsy, which focuses on handmade and vintage goods.
The latest data on the UK’s e-commerce sector
Investment into high-growth e-commerce companies soared in 2021: amount raised via announced equity deals increased from just £63.1m in Q1 2020 to a peak of £552m in Q4 2021. But the end of most COVID-19 restrictions in the UK, combined with the ongoing cost of living crisis, has seen investment into the sector fall back down. The amount invested into UK e-commerce companies in Q2 2022 is still relatively high compared to pre-pandemic levels, however, at £305m. In terms of deal volume, just 30 equity rounds were announced in Q2 2022, compared to 42 in the previous quarter and a record 44 announced in Q2 2021.
The UK is currently home to 1,611 high-growth e-commerce companies. Of these businesses, 36% are operating at the seed stage, meaning they’re young startups, with a low employee count and valuation, and few fundraisings under their belt so far. Whereas, 28% of e-commerce companies in the UK are established-stage firms, which have typically been trading for 15+ years. So the sector’s stage of evolution breakdown is fairly evenly spread at the moment, with plenty of exciting new startups likely to scale in the coming months and years.
Within the UK e-commerce market, 61% of companies have an all-male founding team, compared to 75% across the UK’s wider high-growth ecosystem—but clearly there’s still a long way to go. With regards to regional disparities, London is home to 38% of the UK’s high-growth e-commerce businesses, with other e-commerce hubs located in the South East (12%) and the North West (9%).
