Johannesburg-Based AI Customer Service Firm Cue Secures $5M to Advance Autonomous Agents and Scale in Africa

Johannesburg-based customer service platform Cue has successfully raised $5 million in a new funding round, co-led by venture capital firm Knife Capital and FAM Investments. The company specializes in developing autonomous AI agents designed to resolve customer inquiries comprehensively, from initial contact to resolution, without requiring human intervention. This significant investment is earmarked for advancing Cue's AI capabilities, specifically for the development of its second generation of AI agents, enhancing its voice and security infrastructure, and expanding its market reach.

The fresh capital will be strategically deployed to strengthen Cue's sales and marketing teams across its primary markets: South Africa and the United Kingdom. With a current customer base exceeding 500 companies across diverse sectors like automotive, retail, and finance, Cue already processes over 500 million messages annually. The company reports impressive annual recurring revenue growth of over 160% and states that its existing AI agents can autonomously resolve more than 60% of customer conversations, with more complex issues routed to human agents.

Cue's operational philosophy prioritizes "automation-first, but never automation only," leveraging AI for high-volume, repetitive tasks while enabling human agents to focus on intricate, sensitive, or relationship-building interactions. This approach positions Cue as a unified platform that addresses the historical fragmentation of customer service channels, offering a comprehensive solution that combines intelligent automation with human oversight. The company aims to deploy these advanced AI capabilities securely across all customer interaction channels.

This investment arrives at a pivotal moment, as advancements in large language models empower AI systems not just to respond, but to reason, make decisions, and execute multi-step tasks. For Africa, this funding highlights the continent's growing role in global AI innovation, demonstrating that startups originating from African hubs like Johannesburg are attracting substantial international investment for cutting-edge technology. It also signals continued investor confidence in the potential of African enterprise software companies, even as overall tech funding trends on the continent stabilize.

This development is particularly significant for South Africa, as Cue plans to deepen its presence and expand its go-to-market strategies within the country. It underscores the capacity of local tech firms to develop and scale sophisticated AI solutions that can compete on an international level, driving both technological advancement and economic growth within the region. The focus on end-to-end autonomous resolution places Cue at the forefront of an emerging category of agentic AI platforms, aiming to complete tasks rather than merely deflect questions.
