Juno

Juno (juno.co), operated by Juno Technology, Inc., is a San Francisco-based owner's representation, development-consulting and construction-management firm for prefabricated, modular and mass-timber multifamily development, working with developers from site feasibility and entitlement through delivery across North America. Juno owns the rights to the Juno Mass Timber System, a field-tested kit-of-parts building system of roughly 33 components configurable into 25+ unit types, proven on the 24-unit Juno East Austin project at 400 Comal St, Austin TX. The current company is the 2024 relaunch ("Juno 2.0") of the venture-funded Juno / Juno Residential founded in 2019 by Jonathan Scherr, BJ Siegel and Chester Chipperfield, which raised roughly $32M from Comcast Ventures, Khosla Ventures and RET Ventures before running out of money; the relaunched firm is led by co-founders Emily Mills Marineau and Jen Canchola. Juno sells professional services and a physical building system, not software: as of this enrichment pass it publishes a marketing site, a mass-timber system page, a contact form, a newsletter signup, terms of service and a privacy policy, and no public API, developer portal, OpenAPI specification, SDK, or machine-readable contract of any kind.

Juno is profiled on the APIs.io network. Tagged areas include Company, Construction, Construction Management, Real Estate, and Multifamily.

Juno’s developer surface includes support and 12 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) 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/.

Agent readiness — checks not met, largest first (exact, from this profile):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document Ask about this →
MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship Ask about this →
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author Ask about this →
Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey) Ask about this →
