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