Dennis is Co-Founder and CEO of Overten AI, where he sets the vision and leads the company in building an AI-native workspace that lets professionals generate fully formatted Word documents, Excel spreadsheets, and PowerPoint presentations from a single prompt, then groups related files into projects so AI reads across every one, catching budget mismatches, deadline conflicts, and scope discrepancies before they reach a client.

A repeat founder, he also co-founded TwinOver, reimagining how people connect through video-driven, interest-based communities, and helped build SasaPay, a payment platform licensed under the Central Bank of Kenya that advances digital financial inclusion. Before Overten, Dennis worked at the intersection of product development, technology innovation, and strategic investing, building teams, launching products, and deploying capital into ventures that push the boundaries of software.

Humphry is Co-Founder and Data Science Lead at Overten AI, building an AI-native workspace that reimagines how people analyse, create, and edit documents through intelligent agents rather than traditional tools. He owns data science strategy across the platform, overseeing the architecture behind the multi-agent system, spanning LLM orchestration (GPT, Gemini, Claude), RAG pipelines for multimodal retrieval, document understanding, and structured content generation for Word, Excel, and presentations.

His work focuses on making AI reliably grounded, context-aware, and practically useful for knowledge workers. He designs and deploys agent workflows that combine LLMs with structured document editing, builds retrieval-augmented generation systems for PDFs, images, and mixed-format documents, and owns the data science roadmap from model selection and prompt engineering to evaluation and reliability.
