May 2026Series CSofina (lead); ICONIQ Capital; Balderton Capital; Tencent; Speedinvest; Accel; Peak XV Partners$100M-Primer raised a $100 million Series C in May 2026, led by Sofina with participation from Peak XV Partners, Accel, Balderton Capital, ICONIQ Capital, Speedinvest and Tencent. The round was described as oversubscribed, and Primer said it has raised $170 million in total funding. The company said the proceeds will fund AI product development and US expansion, with a goal of lifting the US share of revenue to more than one third by 2028. Primer is a London-based unified payments infrastructure platform founded by former Braintree and PayPal executives. Its payment orchestration software serves merchants across ecommerce, travel, fintech and digital platforms, and the company positions it as an AI-enabled operating layer for global payments and finance.
Oct 2021Series BICONIQ Capital (lead); Balderton Capital; Seedcamp; Speedinvest; RTP Global; Accel$50M$425MPrimer is a London-based fintech startup founded in early 2020 by ex-PayPal and Braintree employees Paul Anthony and Gabriel LeRoux, offering a low-code payments infrastructure platform with a drag-and-drop workflow editor and API for merchants to integrate payment methods like Apple Pay and Klarna, connect gateways such as Stripe, Checkout.com, and WorldPay, and build customized checkout experiences without extensive coding. The platform also enables third-party developers to create open integrations for services including fraud detection, data warehousing, and customer messaging, acting as an automation framework for payments across web and mobile. On October 19, 2021, Primer closed a $50 million Series B funding round led by ICONIQ Growth, with participation from existing investors Accel, Balderton Capital, Seedcamp, Speedinvest, and RTP Global, achieving a post-money valuation of $425 million—six times higher than its prior $18.7-$20 million round in November 2020. This marked the company's second raise in under a year, signaling rapid growth since launch. ICONIQ Growth partner Roy Luo joined the board, highlighting Primer's potential to disrupt payments amid rising complexity from mobile payments, digital wallets, buy-now-pay-later, and other innovations. At the time, Primer operated remotely with around 75 employees across 20 countries, planning to triple headcount to 250, and served merchants in Europe, Asia, and North America with over 45 integrations. The funds were earmarked for global expansion, product development including new operations and observability tools for payment stacks, and deepening ecosystem relationships to support e-commerce merchants and payment facilitators. Primer positions itself against fragmented payments tech by providing a unified orchestration layer, competing in a market accelerated by consumer demands and backed by high-profile investors like those supporting Adyen, Marqeta, Snowflake, and Datadog.
Nov 2020Series AAccel (lead); Balderton Capital; Seedcamp; Speedinvest; Kinled Holding; RTP Global$19M-Primer is a B2B SaaS platform providing unified infrastructure for global payments and commerce, enabling merchants to optimize performance, build efficiently, and capture revenue through intelligent routing, automatic fallbacks, and support for over 45 integrations without handling funds directly. It operates on a usage-based fees and enterprise licensing model with high gross margins due to its asset-light, cloud-based approach and fully remote operations across 26 countries. The company raised a £14 million ($18.7 million equivalent) Series A round in late 2020 led by Accel, following a £3.8 million seed round led by Balderton Capital earlier in 2020. Subsequent funding included a $50 million Series B in October 2021 led by ICONIQ Growth at a $425 million valuation, bringing total equity raised to approximately $74 million across three rounds. Later data shows £2.9 million revenue in 2023 with £15.6 million operating losses, indicating early-stage revenue concentration risks with key customers like GetYourGuide and Lime.
May 2020SeedBalderton Capital (lead); Seedcamp; Speedinvest; Taavet Hinrikus$4M-Primer is a London-based fintech company founded in early 2020 by ex-PayPal and Braintree employees Paul Anthony and Gabriel Le Roux. It provides an automation platform for payments, enabling merchants to consolidate their payments stack, connect payment service providers like Stripe, Checkout.com, and WorldPay via a unified API, and build customized checkout experiences with drag-and-drop workflows. The platform supports optimization for cost, authorization rates, fraud reduction, and expansion into new markets with local payment methods such as Klarna and GoCardless. In May 2020, Primer raised a £3.8 million seed round led by Balderton Capital, with participation from Taavet Hinrikus (co-founder of TransferWise), following a £600,000 pre-seed from Seedcamp, Speedinvest, Kima, and angels. The funds supported building the payments infrastructure and analytics tools for merchants. Primer demonstrated early traction with merchants across Europe using multiple PSPs like Stripe, Braintree, Adyen, and PayPal, plus local integrations. The company later raised a Series A in late 2020 led by Accel and a $50 million Series B in October 2021 led by ICONIQ Growth at a $425 million valuation.
