Fifth Dimension

Fifth Dimension AI is a London-based decision intelligence platform for real-assets investors and asset managers. Its AI co-worker, Ellie, automates document-heavy real estate workflows — deal screening, underwriting, due diligence, and lease and investment analysis — by reading email bodies and PDF attachments and returning transparent, sourced, auditable reasoning rather than black-box answers. Founded in 2023 by Johnny Morris and Dr. Kate Jarvis, the platform integrates with existing property management, CRM, data room, and financial systems and preserves each fund's institutional knowledge and investment criteria. The company is backed by HV Capital, Seedcamp, Speedinvest and Anthemis, and raised a $26M Series A in 2026.

Fifth Dimension is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Real-Estate, PropTech, and Decision Intelligence.

Fifth Dimension’s developer surface includes engineering blog, pricing, support, and 9 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/fifth-dimension: open an issue to ask a question, or submit a pull request to add artifacts.
