Independent literary studio — San Francisco

A studio for readers, writers, and books.

Verb Foundry builds Vesper, an agentic-AI book recommendation app, alongside original fiction and the Write on Track newsletter — three ways of paying close attention to books and literature.

The flagship — Vesper

A reader's taste, read back to them.

Vesper is an agentic AI that powers Verb Foundry's book recommendation app. Instead of leaning on bestseller lists or star averages, Vesper evaluates books across more than a dozen characteristics — the qualities that shape how immersive, lasting, and accessible a book really is — and matches readers based on their preferences across those axes.

The studio

One roof over fiction, writing, and software.

Verb Foundry is an independent literary studio based in San Francisco, founded by Noor Rahman, a former litigator who left law practice to write and build things for readers.

We keep our fiction, our newsletter, and our software in one place because they're really one question asked three ways: what makes a book worth a reader's time — and how do you help the right book find the right person?
