Alloovium, a five-person startup in Y Combinator's Summer 2026 batch, has launched an AI document layer for construction that reads contracts, specifications and drawings and returns answers cited to the exact clause. In its July 13, 2026 YC Launch post, the company said it was deploying across $400 million in active projects, a self-reported figure that has not been independently verified.
Builders run on paperwork scattered through SharePoint folders, email threads and requests for information, or RFIs. Alloovium's pitch is that an AI tool earns trust only if it can point back to where an answer came from.
What the product does
On its Y Combinator profile, Alloovium calls itself "the company brain for construction companies." Its About page goes further, describing "the intelligence layer for the built world" and promising that "every answer links back to the exact drawing, page or clause it came from."
According to the company's documentation, the core product answers questions over project files: contracts, specs, drawings, emails and RFIs. A separate "conflict scan" compares those documents against one another and surfaces contradictions, each with a citation. A demo on the product page drafts an RFI directly from a flagged conflict.
For builders that maintain a formal management system, the company said it runs "continual compliance sweeps" against the builder's Integrated Management System, or IMS. In its July 13 YC Launch post, Alloovium said the first end-to-end sweep produced 39 cited findings on a single project. Anything the AI drafts requires human approval, the company said.
Running site operations by phone
The company also markets voice-based site operations. A user calls an AI "project line," and Alloovium prepares site update forms, checks requirements against project documents and drafts follow-up messages for approval. The site pairs this with a workflow builder and a "requirement checks" interface.
RuntimeWire profiled the approach on Oct. 25 in a piece headlined "Startup Spotlight: Alloovium turns construction calls into AI-checked workflows."
Developer pages describe further use cases. One is a contract intelligence pipeline that extracts obligations and milestones and pushes them to ERP or project-management tools by webhook, meaning an automated message sent between software systems. Another is a payment-claim cross-reference engine built around Australia's security-of-payment law, known as SOPA. The pages also list a checker for "flow-down" terms between head contracts and subcontracts, an extension-of-time and delay analysis engine, and a variation quantum assessor, which values changes to the scope of work.
Sitting on top of existing systems
Alloovium does not ask customers to abandon their software. Its documentation lists integrations with SharePoint, Outlook, Procore, Google Drive and Autodesk, plus "15+ other systems," and the company stresses that syncing is read-only.
Data handling is a sensitive point in a trade where contracts carry commercial secrets. The company's Data Handling Commitments state: "We do not use your documents to train AI models." The page says documents are not shared across customers and that customer data is deleted within 30 days of disconnect or closure. It lists AES-256 encryption at rest, TLS 1.2+ in transit, AWS hosting and SOC 2 Type II controls. Large language models are used at inference time only, the company said, and that restriction is contractually binding under its data processing agreement.
Traction and team
The $400 million figure comes from the July 13 YC Launch post, which said the company was deploying across that value of active projects, "including a subsidiary of BMD." No other customer is named, and as of October the public site carried no logos or case studies. The number is the company's own, dates to July and August, and could not be independently verified.
An ISO compliance product was in beta in July with a 30-year auditor as design partner, according to the same post.
Cielo Nicolosi wrote on LinkedIn in August: "We're already live across $400M in active projects and expanding into the US." She also described a US Innovation Partner Program kicking off. Mitchell Harmer, who said he joined as chief commercial officer, wrote: "Construction doesn't struggle because people don't care. It struggles because the paperwork isn't a pile. It's a web."
Omar Elloumi is co-founder and chief product officer. His YC profile says he spent three years at LexisNexis turning machine-learning research into production systems for regulated legal data. The profile lists a team of five and a San Francisco location, while the company's site references both Sydney and San Francisco time zones. Crunchbase lists the legal entity as Alloovium Pty Ltd.
Funding
The sources reviewed do not describe a priced equity round. Nicolosi's LinkedIn profile says the company "raised over $1M pre-seed, first from Startmate, then Y Combinator," a self-reported figure. CB Insights lists a $0.5 million convertible note dated June 2, 2026. Crunchbase shows YC and Startmate as investors but does not disclose amounts.
A crowded field
The category is filling quickly. Trimble agreed on April 2 to acquire Document Crunch, and an SEC 10-Q confirmed a $246.4 million close. Document Crunch launched a project-level AI risk platform on June 9, and on Oct. 21 Trimble announced drawing-review risk intelligence.
Procore announced its AI Experience on May 21, including a Deep Search Agent that covers specs, drawings and RFIs and sits inside its system of record. Autodesk offers AutoSpecs, which generates submittal logs from specifications, and an Assistant for conversational search. Trunk Tools launched Cortex on June 17, and UpCodes added AI plan review on June 3.
Alloovium's counter is the overlay: it works across Procore, SharePoint and Autodesk rather than inside any one of them.
The company said it is seeking introductions to ENR Top 400 contractors, the trade publication's ranking of the largest US builders, as it builds out its American push.
