LeO

LeO is an AI-powered sales and prospecting platform for commercial insurance professionals, serving property & casualty (P&C) brokers, employee benefits advisors, and nonprofit insurance specialists. The platform pairs a commercial-lines prospect database of 25M+ US businesses and 200+ filters -- NAICS codes, revenue thresholds, workers' compensation, DOT/FMCSA records, OSHA compliance history, Form 5500 benefits and pension filings, and IRS 990 nonprofit data -- with a renewal-date (X-date) database carrying key contacts and AI-predicted renewal months. LeO generates AI-personalized email outreach, produces pre-meeting intelligence on incumbent carriers, brokers, coverage and risk gaps, and pushes qualified prospects to CRM or CSV export. Founded by CEO Liri Halperin Segal, LeO is a Techstars portfolio company and has been certified HIPAA compliant by an external auditing firm. Alongside the subscription web application it ships two programmatic surfaces: a REST "Leo Public API" at api.meetleo.com with a published OpenAPI 3.0.0 definition covering account, credits, prospect search and asynchronous contact enrichment, and a first-party, OAuth-protected MCP Connector at mcp.meetleo.com marketed for Claude, ChatGPT, Gemini and Copilot. Both are entitlement-gated to existing customers and metered in credits.

LeO publishes 4 APIs on the APIs.io network, including Public API, Health API, and 2 more. Tagged areas include Company, Insurance, Commercial Insurance, Property and Casualty, and Employee Benefits.

LeO’s developer surface includes pricing, signup flow, support, FAQ, engineering blog, documentation, API reference, and 23 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Insurance 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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

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/leo: open an issue to ask a question, or submit a pull request to add artifacts.
