London-based Simpler raises €9 million to transform the checkout experience | EU-Startups

Simpler, a platform transforming the way merchants handle checkout by providing a unified, one-click buying experience across all channels, has raised €9 million from new and existing investors, including VentureFriends, MMC Ventures, Lamda Development, VGC, among others (lead investor undisclosed). This capital will fuel Simpler’s expansion into key European markets, including the UK, Italy, and Spain, while driving further innovation to make the checkout process faster, more seamless, and more intuitive for customers.

Merchants often struggle with integrating multiple, disjointed solutions for checkout flow, payment processing, shipping, and loyalty programmes—leading to inefficiencies, higher costs, and lower conversion rates. Simpler is addressing this problem directly with its one-click purchase solution including a fully integrated payment suite, allowing merchants to streamline the checkout process for shoppers without managing complex infrastructure. This simplified approach boosts conversions and makes it easier for customers to complete their purchases.

While platforms like Shopify claim to have the best converting checkout, Simpler is bringing an even more advanced solution to merchants on any platform. With Simpler’s Checkout as a Service (CaaS) offering, merchants can fully outsource their entire checkout infrastructure—managing everything from the checkout flow, payments, and shipping to loyalty programmes all within a single, unified system. By eliminating the need for multiple integrations and delivering a frictionless checkout experience, CaaS reduces technical complexity, boosts conversion rates, and helps merchants focus on growth.

“Our mission has always been to eliminate the complexities of managing multiple systems and provide merchants with a single, unified checkout solution,” said Rania Lamprou, Co-founder and CEO of Simpler. “This funding enables us to accelerate our expansion across Europe and build on our Checkout as a Service (CaaS) platform, empowering businesses to offer a frictionless, high-conversion shopping experience while focusing on growth rather than technical challenges.”

With the new €9 million investment, Simpler will accelerate its growth in Europe, bringing its unified checkout solution to merchants in the UK, Italy and Spain. These funds will support business development and platform enhancements, ensuring that businesses of all sizes—from independent retailers to large enterprises—can benefit from Simpler’s comprehensive checkout infrastructure.

“As we scale across Europe, our goal is to help merchants deliver a world-class checkout experience that drives conversions and builds customer loyalty,” added Lamprou. “We’re committed to simplifying every step of the transaction process, making it easier for businesses to grow and for customers to enjoy a seamless shopping experience.”
