Maincode

What Maincode does

Maincode is an Australian AI research and product company headquartered in Melbourne that builds custom AI models and infrastructure, anchored by its flagship AI assistant Matilda. Matilda is designed for deep contextual understanding across long conversations, multi-step reasoning with inspectable steps, anticipatory but consent-based action, and personalised workflow learning, and is hosted entirely in Australia to align with Australian privacy and data sovereignty standards. Underlying Matilda is a proprietary stack that includes a long-context reasoning framework (context-engine), a tool-use and agentic execution layer (action-layer) with sandboxing, an internal evaluation framework covering 10K+ scenarios (eval-suite), and a custom GPU inference infrastructure (inference-cluster) running on vLLM, Kubernetes, Terraform, and GCP to deliver sub-200ms response latency globally.

Maincode's revenue model is multi-stream but largely pre-monetisation at present. Matilda is offered via a private beta with an early-access request flow and via API for developers, indicating a subscription and usage-based design. The MC-2 AI factory, a $30M sovereign AI infrastructure built on AMD Instinct MI355X GPUs, targets Australian enterprises in regulated sectors with managed, multi-year infrastructure contracts and a stated 1.5-1.8x TCO advantage over comparable NVIDIA-based solutions. Matilda is also embedded as the processing LLM within Mastercard's Agent Pay framework via IPSI, demonstrated in New Zealand's first fully authenticated agentic transactions with Westpac, Event Cinemas, and QT Hotels.

Go-to-market blends product-led growth (private beta, API, research residency) with enterprise field sales (regulated Australian accounts) and OEM/embedded distribution (Mastercard). The customer footprint spans knowledge workers via Matilda, Australian regulated enterprises via MC-2, and financial institutions and merchants via the Agent Pay ecosystem. Maincode is privately held, founder-controlled, with no disclosed external equity investors beyond the $30M corporate commitment tied to the AMD partnership.
