RapidSpike

What RapidSpike does

RapidSpike Limited is a UK-based SaaS company headquartered in Leeds that has operated since 2015 as a digital experience monitoring platform specialised in eCommerce websites. The platform delivers synthetic user journey monitoring (Synthetics), real user and third-party script monitoring, performance monitoring keyed to Core Web Vitals and automated Google Lighthouse scoring, uptime and API HTTP monitoring, and a dedicated cybersecurity sub-brand called CartShark that targets client-side Magecart/web skimming attacks at checkout. Underlying technology includes a Selenium WebDriver-based synthetic scripting engine, a distributed check infrastructure hosted on AWS (the company is an AWS Partner Network member), an AI/ML-driven detection engine scanning 125M+ endpoints daily, and PCI DSS v4.0 tooling aligned to requirements 6.4.3 and 11.6.1. A REST API documented for journey submission and reporting, plus a native JSON-based data model, supports both direct and partner integrations.

The company makes money primarily through recurring SaaS subscriptions billed monthly or annually, with fees varying by plan scope, feature tier, and usage limits; CartShark is additionally distributed through the Shopify App Store and WordPress Plugin Directory as a self-serve subscription on top of the direct-sales motion used for the full platform. Optional professional and managed services, including a new DigitalOps 'operations as a service' package targeted at agencies, supplement subscription revenue. Go-to-market spans three motions: product-led growth via CartShark on app stores for SMB merchants; enterprise field sales for global multi-site brands such as JD Sports, Kurt Geiger, Revlon, Hydro Flask, Braun, Sofology, and Sweaty Betty; and an agency partner/reseller channel that delivers monitoring as a managed service to merchant clients. Travel, gaming, and public-sector verticals are additionally addressed. Revenue, pricing tiers, and customer concentration beyond disclosed logo names are not publicly disclosed; the company has raised disclosed equity of approximately $2.0M cumulatively (a 2015 seed round and a 2020 Praetura Ventures-led round of $1.30M) and was awarded a non-dilutive Innovate UK Smart Grant in July 2024 to develop an AI-driven website monitoring platform.
