Fifth Dimension is a London-based AI company building a decision-intelligence platform for real assets. Founded in 2023 by Dr. Kate Jarvis and Johnny Morris, its flagship AI assistant, Ellie, pulls unstructured data from leases, surveys, and deal documents, organizes it into formatted templates, and automates the document-heavy workflows that slow down real estate investors, lenders, and asset managers. In May 2026 it raised a roughly $26M (€22M) Series A led by HV Capital to scale across the UK and US.
Dr. Kate Jarvis is the CEO and co-founder of Fifth Dimension, the London-born AI company building Ellie, an agentic assistant that screens deals, drafts investment-committee memos and surfaces risk for the people who buy and manage real assets. A Stanford linguistics PhD turned backend engineer, she spent a dozen years shipping machine-learning products before GPT-3 convinced her that real estate's mountains of unstructured documents were a problem language models were born to solve. She has raised more than $40M, opened offices in London, New York and Singapore, and put firms like BXP and Realty Income on her platform.
