Construkt

Construction runs on fragmented documents, informal payment agreements, and slow sign-offs. There is rarely a single source of truth when something goes wrong. Construkt is our MVP answer, one place where milestones, approvals, variations, and releases line up on chain so both sides can see the same story.

What we kept hearing was messy in practice.

• Payment agreements buried in email threads
• Contractors and clients working off mismatched document versions
• No trustless way to enforce “pay only when agreed conditions are met”
• No durable audit trail when disputes appear months later

We shipped enough to demo end to end. Escrow on Solana where funds stay locked until both contractor and client approve, then release; milestones visible to both sides; and an on chain trail for approvals, variations, and payments so the history does not disappear when someone changes a PDF offline.

There is a web front end for the two roles, Solana programs backing the rules, and we sanity-checked the product by talking to people who actually work in construction, not only to ourselves.

We sketched it as B2B SaaS, a monthly subscription scaled to project size, plus a small fee when escrow actually releases. The wedge is not “another document portal” but enforced settlement and an immutable record when money moves.

Incumbents like Procore or Oracle are centralised platforms with strong workflow tools, but they do not give you trustless payment enforcement or a permanent, neutral audit trail on a public ledger. Construkt’s angle is simple. The authoritative trail and the funds only move when the chain of authorisations says they can.
