Pre-seed stage. Smart contracts deployed. MVP live. $13T market with zero dominant platform. Seeking co-investors and the right co-founders to build the category.
Lost to construction disputes, defects, and unverifiable warranty claims every year. The industry has no standard, tamper-proof way to issue, track, or verify warranties.
Build Register creates an immutable, tamper-evident layer for construction warranty management — backed by smart contracts, accessible through a dashboard any stakeholder can use without knowing what a blockchain is.
Every project, vendor, and asset registered on-chain with completion dates, responsible parties, and handover references.
Structural, waterproofing, HVAC, electrical — each warranty issued as an on-chain record with a unique certificate ID and verifiable expiry.
Supporting documents hashed and anchored via IPFS — creating a tamper-evident paper trail tied to every warranty record.
File, track, and escalate warranty claims through a structured lifecycle — Logged → Submitted → Inspecting → Resolved.
Anyone can verify a warranty certificate using its ID. No login required. Built for owners, regulators, and insurers.
AccessManager contract governs who can issue warranties, log claims, and attach documents — no rogue edits, no data drift.
This isn't a whitepaper or a concept. The smart contracts are deployed, the dashboard is live at app.build-register.com, and real data is being written to the Nexus Testnet right now.
Designed to feel familiar to construction professionals, backed by immutable on-chain records.
Construction is one of the world's largest industries and one of the least digitised. Warranty and defect management alone represents a multi-billion dollar problem that no blockchain-native platform has solved at scale.
Build Register's approach — starting with the registry layer and expanding — mirrors how Stripe started with payments primitives, not a consumer product. Own the infrastructure, data flows on top.
Nexus Testnet is our proving ground. Mainnet deployment and the first enterprise pilot are the immediate next milestones.
We're at a critical moment — contracts deployed, MVP live, clear product direction. We're looking for the right people to build the category.
Full-stack or blockchain engineer who wants to own the technical direction. Solidity, React, or both. Equity-based, remote-first. Help shape what gets built next.
Someone with deep construction, real estate development, or property management networks who can open doors to pilot clients and validate the product direction.
Pre-seed capital to fund mainnet deployment, first enterprise pilot, and core team growth. Infrastructure play in a very large, very underserved market.
"I've built the contracts, the dashboard, and the deployment pipeline. The product works — you can connect a wallet and write to the chain right now. What I need are co-builders who believe that construction deserves the same trust infrastructure that finance has had for decades."— Karim, Founder of Build Register Get in Touch →
The dashboard is live. The contracts are deployed. You can connect a wallet and write to the chain right now.
