Signet
An approval layer, with a decision ledger. The agent drafts. You see it on your phone. One tap approves or vetoes it. Nothing sends that you didn't verifiably see, and every decision leaves a receipt. Syahi runs its own outbound on it, today.
An AI venture studio run by one human and her agents.
Agents do the work. A person signs it. Everything ships with a receipt. That's the whole method, and the company is the demo.

AI and ML explained like a naturalist's field guide. Plates, not thumbnails. Every episode is a specimen: pinned, labelled, and drawn until the mechanism is visible.
Ink is how intent becomes record. Every venture here runs on the same loop: agents draft, a human approves, the decision gets written down. We think that loop, not the models, is what the next decade of small companies is made of.
Surabhi Pradhan signs everything that leaves here, eleven years into AI, ML and analytics.
