Founder & Operator, CallHush
Founder and operator of CallHush. The offer is one sentence: you run a webinar, and we increase your show-up rate and your post-webinar sales with an AI voice and SMS system. CallHush has no closed clients yet — the first engagement is a pilot run as a split of the client’s own registrant list, and nothing on this site is presented as a client result.
What the work is
The sequence around a webinar
A two-way text when someone registers that asks why they signed up. A call and a text before the session. A run of calls, texts and email afterwards while the offer is still open. None of it needs an event from the webinar platform — it runs off the registration record and our own timer.
An assistant that says it is one
The voice identifies itself as an assistant at the start of the call, before anything else happens. It is not softened and it is not held back for whoever thinks to ask. The mechanism does not need the listener to believe they are talking to a person: the registrant is persuading themselves, not the caller.
Consent, revocation and calling rules
Prior express written consent captured on the registration form in the client’s own name, never pooled across clients. Revocation by any reasonable means, processed inside the ten business days the FCC allows. Calling hours enforced in the registrant’s local time, not the operator’s.
Knowing why every registrant signed up
The thread that opens at registration produces something no reminder sequence produces: each registrant’s own words about why they are coming. That is a working asset — for the pitch, for objection handling afterwards, and for the next round of ads.
What there is no proof of yet
- No closed clients. Not one. So there is no case study, no logo, no testimonial and no result on this site, and there will not be an invented one.
- No published call recordings. The recordings on hand are from other projects and have not been cleared for publication, so none is published — including the good ones.
- No claim that a disclosed AI caller performs like a human one. The research this offer is built on used live human callers. Whether the effect survives at full strength when the caller announces itself as an assistant is unestablished — which is exactly what a split of your own registrant list would measure.

The "40-45% Webinar Show-Up Rate" Benchmark Everyone Cites Is Fake
The only paid-traffic webinar show-up-rate benchmark on the open web launders a nonexistent "12,400 webinars analyzed by ON24, GoTo, and BrightTALK" study. Traced step by step, checked against what those three companies actually publish, and replaced with the sourced 21-36% range.
Why a Phone Call Beats a Reminder — and Why a Reminder Alone Won't Fix Your Show-Up Rate
A generic reminder call moved nothing in the largest field experiment ever run on this question (N=287,228). A call that got people to state a specific plan moved attendance by 4.1 percentage points among those reached. The difference is the micro-commitment, not the channel.
