aid: katerra name: Katerra description: >- Katerra was a Menlo Park, California off-site construction and building-technology company founded in 2015 by former Flextronics chief executive Michael Marks with Fritz Wolff and Jim Davidson, built on the thesis that a single vertically integrated firm could design, engineer, manufacture and assemble buildings end to end — running its own architecture practice, factories in Phoenix, Tracy and Spokane producing cross-laminated timber and prefabricated wall, floor and bathroom assemblies, and its own supply chain and general contracting arm. It raised more than $2 billion across a dozen rounds, including an $865M Series D led by the SoftBank Vision Fund in January 2018 at a valuation above $3 billion and a $200M recapitalization in December 2020 that handed SoftBank majority control. Its only software product was Katerra Apollo, announced in February 2019 as a design-to-field platform (Apollo Construct, Apollo Insight, Apollo Connect) whose launch materials promised "open API integration" with existing construction workflows — but Apollo was sold to Katerra's own construction customers and never shipped a public developer portal, API reference, SDK or machine-readable specification. The insolvency of its SoftBank-backed lender Greensill Capital cost Katerra its bonding capacity, and the company shut down and filed Chapter 11 in the Southern District of Texas on 6 June 2021. Its assets were broken up: the Apollo software went to Builders FirstSource for roughly $4.5M on 9 September 2021, and the factories were sold separately. katerra.com no longer serves a site — it answers a Cloudflare error 1001 on every path and cannot complete a TLS handshake at all. This profile is retained as a historical record; there is no API surface left to catalog. url: https://raw.githubusercontent.com/api-evangelist/katerra/refs/heads/main/apis.yml image: https://web.archive.org/web/20190712083445id_/http://katerra.com/content/dam/katerra/www/en_us/assets/images/logo/katerra.jpg/_jcr_content/renditions/cq5dam.web.1280.1280.jpeg x-type: company x-source: harvest:secondary-market x-tier: stub x-tier-reason: defunct-no-api-surface x-status: defunct x-founded: '2015' x-shutdown-date: '2021-06-06' x-shutdown-note: >- Announced its shutdown and filed for Chapter 11 bankruptcy in the Southern District of Texas on 6 June 2021 after the insolvency of its lender Greensill Capital removed its ability to procure construction bonding and no further capital could be raised. x-successor-note: >- The Katerra Apollo software assets were acquired by Builders FirstSource (NYSE: BLDR) for approximately $4.5M on 9 September 2021 and folded into that company's digital tools alongside WTS Paradigm. Apollo is not published by Builders FirstSource as a public API either, and any contract on a bldr.com host would belong to Builders FirstSource, not to Katerra, so nothing is wired here from the acquirer. x-domain-status: dead x-domain-note: >- katerra.com still resolves (Route 53 nameservers, Cloudflare edge addresses) but serves no origin: http:// returns HTTP 409 with Cloudflare "error code: 1001" on every path including all /.well-known/* and spec paths, and https:// fails the TLS handshake outright. Wayback captures show this same 409 error page continuously from April 2022 onward. api., docs., developer., apollo. and app.katerra.com do not resolve at all. It is dead, not parked, and is deliberately not wired as a Website pointer. See well-known/katerra-well-known.yml. x-github-note: >- Three GitHub organizations carry the name (github.com/Katerra, github.com/katerrainc — whose profile blog is katerra.com — and github.com/Katerra-inc). All three have zero public repositories, so no GitHubOrganization pointer is wired: the org shells exist but publish nothing. specificationVersion: '0.23' created: '2026-08-23' modified: '2026-08-23' tags: - Company - Defunct - Construction - Construction Technology - Building Materials - Modular Construction - Prefabrication - Manufacturing - Real-Estate - Supply Chain tags_raw: - Company - Defunct - Construction - Construction Technology - Building Materials - Modular Construction - Prefabrication - Manufacturing - Real Estate - Supply Chain apis: [] maintainers: - FN: Kin Lane email: kin@apievangelist.com - FN: APIs.json email: info@apis.io common: - type: SecondaryMarket url: https://forgeglobal.com/katerra_stock/ x-enrichment: date: '2026-08-23' status: minimal artifacts_added: 1 pass: local-v1 x-coverage: state: none reason: defunct detail: >- Katerra shut down and filed Chapter 11 on 6 June 2021 and its Apollo software was sold to Builders FirstSource that September; katerra.com now answers Cloudflare error 1001 (HTTP 409) on every path and refuses a TLS handshake entirely, api/docs/developer/apollo subdomains no longer resolve, and 4,068 archived katerra.com URLs contain no developer portal, OpenAPI, Swagger or SDK — only Adobe Experience Manager site JSON such as /bin/www/projects.json — so there is no API surface to profile. evidence: - url: http://katerra.com/ status: 409 - url: http://katerra.com/openapi.json status: 409 - url: http://katerra.com/.well-known/agent-card.json status: 409 - url: http://katerra.com/llms.txt status: 409 - url: https://api.github.com/orgs/katerrainc status: 200 checked: '2026-08-23'
