Kranth — synthetic audience infrastructure

Kranth stress-tests ideas against adversarial AI personas before strangers do. You POST copy, a pricing change, a feature brief, or a policy draft. The engine seats 10 to 10,000 personas drawn from 101 archetypes and 8 voice axes. Each persona reacts independently. You get a live stream plus a verdict: sentiment from −1.0 to +1.0, a hostile / neutral / aligned breakdown, top objections, themes, and representative quotes.

Kranth is not a market forecast and not a replacement for real users. It is a pre-build, pre-spend stress test so teams find the objection while changing direction is still cheap. Four modes: Simulations (independent reactions and a scored verdict), Debate (structured formats including 1v1, panel, town hall, press, and pre-mortem), Recon (web-grounded research swarm with citations and PDF), and Interview (you are the subject).

About Kranth

Kranth AI, Inc. is a Delaware C-corporation founded 11 June 2026. The product is self-serve infrastructure for operators who ship — product, research, and strategy teams that need dissent on demand. Convictions: feedback is infrastructure, not a meeting; synthetic is not shallow and is not real users; models fail loudly rather than pretend; no outside capital narrative driving the roadmap. Registered office: 131 Continental Drive, Suite 305, Newark, Delaware 19713, United States.
