Black Ore Technologies

Black Ore Technologies is an Austin, Texas AI company building AI infrastructure for tax and financial services. Founded in 2022 by Eyal Shinar (previously founder of the fintech unicorn Fundbox) and Pavel Kapovski, the company emerged from stealth in November 2023 with $60 million in funding led by Andreessen Horowitz (a16z) and Oak HC/FT. Its flagship product, Tax Autopilot, combines proprietary AI with federal and state tax codes to autonomously execute the full lifecycle of complex tax returns for Certified Public Accountants and accounting firms, spanning document ingestion, intelligent extraction, return preparation, workpaper generation, and tax software integration (UltraTax, Lacerte, ProConnect). The platform covers 1040 individual returns plus 1041, 1065, and Schedule K-1/K-3 automation, and is used by 40% of the top 20 leading firms. Black Ore does not publish a public developer API or OpenAPI at this time; its authentication is handled by an Auth0-hosted OpenID Connect tenant at auth.blackore.ai.

Black Ore Technologies is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Financial-Services, Tax, and Accounting.

Black Ore Technologies’ developer surface includes support, pricing, engineering blog, signup flow, authentication, and 12 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/black-ore-technologies: open an issue to ask a question, or submit a pull request to add artifacts.
