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 16 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the AI & Biometrics regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
RPA and Document AI (RPA marketplaces, intelligent document processing)	undeclared	-	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
