Three products, one rule
Vellarin AI is the company behind three products where the AI carries the load and a person signs off: Vellarin Agents, an AI team for the everyday work of a business; BidStream, the bid workflow for specialty contractors; and Vellarin Hub, which connects your own AI agents to your team’s apps.
3
products, built and run by the same company
7
stages of a bid covered by BidStream
3
ways to run your agents: your computer, our cloud or a Vellarin Box
1
rule in all three: a person approves what matters
Products
One is for the everyday work of any business. One is for contractors who price work from drawings. One is for teams that already run their own AI agents.
Vellarin AgentsFree to start
A team of AI agents that works on your computer with the AI you already pay for. You approve what goes out.
Vellarin BidStreamLive
Seven stages of preconstruction in one workflow, from opportunity to post-bid.
Vellarin HubFree to start
Point Claude Code, Cursor, Codex or your own agent at one address with one key, and it gets the apps your team connected.
Shared principle
It is the same rule in all three products, and it is built into the software, not written in a manual.
By default a person approves money, legal commitments, customers’ personal data and outside messages.
Spending limits are checked before each run, not after it.
An activity log shows the cost of each step, and BidStream quantities trace back to their sheet.

Three products. Vellarin Agents, a team of AI agents for the everyday work of a business: create an account at agents.vellarin.ai and start free. BidStream, preconstruction software for specialty contractors: it starts with a 30-minute call on a real bid of yours. Vellarin Hub, which connects the AI agents you already run to your team’s apps under your approval: get your key at hub.vellarin.ai.
They take on the recurring work you define, each with a role, tasks and a reporting line. You see who is working on what, and a person approves anything involving money, legal commitments, customers’ personal data or messages sent outside the company.
Yes. You can create an account at agents.vellarin.ai, hire your first agent and give it a job today. It is free to start on your own computer.
AI-assisted construction takeoff software, built by Vellarin. Upload the plan set as PDF, confirm the scale, and BidStream helps you count, measure, mark up and organize quantities — with every proposed count visible on its source sheet so your team can approve or correct it.
No, and we don’t want it to. AI proposes; the estimator approves. A takeoff produces quantities — a complete estimate also depends on labor, materials, equipment, production rates, subcontractor quotes, waste, overhead and commercial judgment. BidStream speeds up the mechanical part and keeps the decisions where they belong.
One address and one key that give Claude Code, Cursor, Codex or your own agent the apps your team connected. Reading runs straight away; anything that writes waits for the workspace owner’s approval. Every key has hard caps and every call is on the record. It is free to start, at hub.vellarin.ai.
