Mosaic

Tech-enabled general contractor for build-to-rent housing

A hybrid construction-and-software company that self-performs general contracting for large-scale (50+ home) build-to-rent residential communities, using its proprietary "Mosaic Hub" platform to digitize construction plans and automate subcontractor contracting, scheduling, and payment. It is not a software product licensed to outside firms as of this research date — Mosaic uses the platform internally to run its own construction operations.

$68.75M+ total disclosed (Series A ~$24.47M in 2020; Series B $44M led by Peak State Ventures, reported as $45.85M in SEC filings, in 2021) per TechCrunch and SEC-filing-based trackers. Investor list per company site includes Andreessen Horowitz (a16z), Building Ventures, Peak State Ventures, AZ-VC, Starwood Ventures, Tekfen, Founders Fund, Greylock, Innovation Endeavors, and Thrive Capital. No public funding round has been reported since 2021 as of this research date. raisedGrowth Stage
Founded 2017 · Not a broad self-serve customer base — Mosaic contracts directly with a small number of large institutional build-to-rent developers (named partners include NexMetro Communities, Crescent Communities, Rockefeller Group, and Mandalay Homes) for 50+ unit communities. Per company statements and an October 2024 Forbes interview: ~1,000 homes completed in under 4 years (550+ built to the DOE Zero Energy Ready standard), ~2,000 homes under active construction and ~7,000 units in the pipeline (2024-2025), 13 active projects. Headcount fell from 110 to 65 employees between roughly early 2023 and mid-2024 even as revenue reportedly grew ~18x over 6 quarters — company frames this as an automation productivity gain, but it is also consistent with cost-cutting and warrants scrutiny.

WHY IT EXISTS

Why This Tool Exists

The Problem

Build-to-rent developers building large residential communities (50+ homes) rely on fragmented, manual coordination across hundreds of subcontractor trade partners for contracting, scheduling, and payment — a process that is slow to scale across markets, hard to standardize, and leaves subcontractors waiting weeks to be paid for completed work, which drives trade-partner churn.

The Solution

Mosaic acts as the general contractor itself rather than selling software: it digitizes standard construction plans, decomposes each project into granular trackable tasks, and uses its "Mosaic Hub" platform to schedule and dispatch trade partners and trigger payment shortly after verified task completion (stated goal: within 24 hours). The company describes construction coordination as "an information problem, not a physics problem" and standardizes its process (not the housing product itself) so it can repeat execution across markets in Arizona and Texas.

Exactly what this tool uses and how

Input
What it needs
Required:Architectural/structural plans for the residential community, Site and development specifications, Subcontractor/trade-partner network and scope data
Optional:Lender/developer payment terms, Zoning/permitting documents
Formats:Architectural and structural drawings (specific file formats not publicly specified), Site survey documentation
Output
What you get
Format:Constructed homes, plus granular internal construction-execution data (scheduling, payment status, trade-partner task tracking) inside Mosaic Hub
Fields:Digitized construction plan broken into granular, trackable tasks, Trade-partner scheduling and dispatch records, Payment trigger/status per verified completed task, Construction progress tracking the company describes as far more granular than typical construction modeling (exact methodology not published)
Algorithm
How it works
Model:Not publicly disclosed — proprietary internal data platform ("Mosaic Hub"); no named AI/ML model architecture published
Accuracy:Not applicable / not publicly specified. Company claims "18x" productivity improvement and construction tracking "1,000x" more granular than typical construction modeling (per an October 2024 Forbes interview); no benchmark methodology has been published for either figure.
