Kong – a leading developer of cloud API technologies – announced it has closed a $175 million in up-round Series E financing (via mix of primary and secondary transactions) at a $2 billion valuation. This funding round was led by Tiger Global and co-led by new investor Balderton, with additional new participation from Teachers’ Venture Growth (the late-stage venture and growth investment arm of Ontario Teachers’ Pension Plan) and 137 Ventures, among others, and continued support from Andreessen Horowitz, Index Ventures, CRV, Sapphire Ventures, and Notable Capital. This brings Kong’s total raised to $345 million.
Kong will use the new funding round to accelerate its global GTM expansion, enhance product innovation with AI-infused capabilities across AI Gateway, Konnect, Insomnia, and all leading API runtimes such as Kong Gateway and Kong Mesh, and invest in the growth of its customer experience teams.
Kong’s unified API platform enables organizations to create AI applications faster while ensuring centralized API security, governance and visibility across all services. And as more companies pivot to becoming API-first, Kong provides the critical infrastructure needed to enable secure and scalable AI solutions.
With this funding round, Kong is prepared to continue transforming API management and AI integration for organizations globally, empowering businesses to stay ahead in an increasingly digital and AI-driven world.
