Lithuanian AI orchestration platform for enterprises, nexos.ai, has emerged from stealth with $8 million in funding. The round was led by Index Ventures with participation from Creandum and Dig Ventures.
It also saw participation from a number of angels, including Olivier Pomel (CEO of Datadog), Sebastian Siemiatkowski (CEO of Klarna), through Flat Capital, Ilkka Paananen (CEO of Supercell) and Avishai Abrahami (CEO of Wix.com).
The nexos.ai platform will launch in Q1 2025, and is already being tested by several major international companies for use cases such as automated customer support.
What challenge does that resolve?
As companies race to integrate AI capabilities, they face mounting complexity in managing multiple AI models, controlling costs, and ensuring reliable performance. nexos.ai is solving one of the most pressing challenges businesses face in 2025 – how to efficiently deploy, manage, and optimise an increasingly complex ecosystem of AI models across their organisations.
How was the idea born?
nexos.ai was founded in 2014 by Tomas Okmanas and Eimantas Sabaliauskas, who is best known for co-founding Nord Security and Oxylabs. The idea emerged from his firsthand experience, where he struggled to integrate AI across several companies he was involved with despite spending over $100k per month on large language models (LLM) usage in some cases.
Conversations with other companies revealed the same pattern: businesses were eager to deploy AI, but lacked the infrastructure to create high-quality, secure, flexible and cost-effective applications at scale.
AI integration made seamless
nexus.ai solves this problem by building an AI operating system for enterprises, enabling them to harness and deploy hundreds of AI models through a single, seamless platform.
The platform provides access to over 200 AI models from leading providers including OpenAI, Anthropic, Google, and Meta. Key capabilities include smart model routing and load balancing to optimise performance and costs, intelligent caching that can significantly reduce costs for repeated queries, comprehensive monitoring and analytics for AI operations, and enterprise-grade security and compliance controls.
“nexos.ai is a critical solution for any enterprise deploying AI at scale, where managing the inherently complex ecosystem of large language models, AI agents, and applications with varying levels of autonomy becomes essential. The demand for such solutions is expected to grow exponentially in the coming months and years,” said Hannah Seal, Partner at Index Ventures. “Tomas and his team have consistently demonstrated their ability to tackle complex challenges by creating products that deliver elegant, simple solutions — and this one might be their most consequential yet.”
“Companies know that AI is an operational and competitive necessity, but they’re drowning in the challenges of managing multiple models, controlling costs and ensuring accurate and reliable performance,” said Okmanas, CEO and co-founder of nexos.ai. “At the same time, AI models are becoming increasingly autonomous and capable of handling complex tasks with minimal human intervention. We’ve built nexos.ai to be the enterprise-grade platform that makes working with AI as intuitive as working with human teams – providing the infrastructure and oversight to make sure these models perform at their best while remaining cost-effective and secure.”
