Clozure review: Pay-per-department AI for lead finding, cold email, sales calls and back-office work

What Clozure does

Clozure is a modular AI platform that covers lead generation, outreach, follow-ups and several back-office functions. Instead of one fixed bundle, you start with a base platform at $99/month, which includes a CEO seat, the COO AI orchestrator, multi-business management and core infrastructure. You then add the departments you need, each priced separately: Lead Generation at $49/mo, Marketing at $79/mo, Sales at $79/mo, Finance at $49/mo, and others at $47/mo to $79/mo.

On the lead side, the vendor says its AI pulls prospects from 11+ data sources and enriches them. For outreach, it drafts, sends and follows up on cold emails through a Microsoft 365 or Google mailbox you connect, or through a mailbox it sets up for you. The features page also lists AI voice calling built on Twilio, invoice generation at deal stages, DocuSeal-based e-signatures and compliance tooling. The vendor notes that SOC 2 Type II tracking is a program in progress.

You can run several businesses in separate containers, and the COO AI is described as coordinating the departments. A 14-day free trial gives access to all departments, but a card is required and is charged once the trial ends. Departments can be added or removed at any time, with prorated billing. The pages do not state supported platforms or API availability.

Our take

Clozure suits a small business or solo founder who wants to hand repetitive prospecting, outreach and follow-up to software and is happy to pay only for the departments it uses. The $99/month base plus $49 to $79 per department is clear enough to budget from. It is a weaker fit if you need a free plan, a stated API, or published platform support, none of which the official pages mention. Most claims on the site, such as savings figures and department counts, are vendor statements, and the pages even disagree on the department count. Inbox placement for cold email is explicitly not guaranteed, so check deliverability during the trial.
