About

Leni is an AI platform for investment professionals, underwriters, portfolio managers, and analysts, who need verifiable answers rather than confident hallucinations on large decisions.

It draws on a context graph of more than 21,000 decision traces, processes over 100 million rows of financial data a day, and grounds every response in source links, timestamps, and reconciled comps that can be audited.

It is used by teams at firms like Bozzuto, Greystar, and CBRE for portfolio analysis, underwriting, market research, and investment memos, and routes across multiple models to keep answers honest. It is aimed at real-estate and investment teams who need an auditable AI back office for high-stakes analysis.

Why we picked it

Leni stood out for citing sources on every answer rather than confident-sounding prose — for investment decisions specifically, a wrong hallucinated number is expensive, so grounding every response in a timestamped source is the feature that actually matters here.
