SaiHey

Every sales team hits the same wall: booking more appointments means hiring more setters, and the people who do it are expensive, inconsistent, and prone to burning out.

SaiHey puts two AI sales reps on the job, Natalia on chat and Romeo on the phone, that set, nurture, and book appointments around the clock, booking more of them at lower cost and never going off-brand.

The situation

For most businesses, booking sales appointments is a people problem. It takes a roster of setters, the reps whose job is turning leads into booked meetings, and that roster is expensive to hire, slow to train, inconsistent, and prone to burnout. When lead volume climbs, the only lever is more headcount, so cost scales with growth and quality drifts. The obvious answer is to automate it, but that raises a harder problem. An AI that talks to real prospects in the company's name, at scale, cannot afford to go off-script. One fabricated claim or mishandled sensitive conversation, and the tool meant to grow the business has damaged it instead.

Why it was hard

Real appointment setting is a multi-stage process, qualifying a lead, nurturing it, following up on the right cadence, confirming before the meeting, and adapting to where each prospect actually is. Doing that at the quality of a good human rep, in the company's own voice, across both chat and live phone calls, is the first hard part. The second is trust, and it is the one that usually kills autonomous sales. An agent speaking to real customers has to stay on-brand and factual every time, because one fabricated claim or off-brand promise is a real liability. It has to recognize a high-risk conversation, a legal threat, an abusive exchange, a sensitive disclosure, and hand it to a human. And it has to honor opt-outs and privacy rules on the spot, or it breaks consumer-communication law. Selling well and staying safe, at once, is the real problem.

The approach

SaiHey runs on a two-agent design that splits the job between selling and safety. A moderator agent sits over every conversation, enriching lead data, scoring the exchange, blocking anything off-brand or fabricated, honoring opt-outs, and escalating high-risk conversations to a human the moment they appear. A multi-phase sales agent does the selling, adapting to each stage of the funnel with tailored follow-ups, nurturing, and confirmations in the brand's own tone. Both run across two channels, Natalia on chat and Romeo on the phone. The system drives the stage-by-stage sales reasoning and the decision to advance, hold, or escalate. Setup runs in under 72 hours and connects to whatever CRM the business already uses.

What happened

The results show on both sides. Businesses using SaiHey have lifted booking rates by more than half and cut cost per appointment by roughly the same, with several replacing whole rosters of human setters, one of them eight setters inside 90 days. Because the moderator agent enforces safety and compliance on every conversation, that scale comes without the off-brand or non-compliant exchanges that make autonomous outreach risky. And because the reps run around the clock across chat and voice, lead volume no longer forces a matching rise in headcount. SaiHey is live and in production for hundreds of founders and businesses, where every conversation is with a real prospect and the brand is on the line.

What this means for you

If your growth depends on booked appointments, you already know the ceiling. Every increase in volume has meant more setters, more cost, and more inconsistency. The bottleneck was never the demand. It was that the work could only scale with people, and no one trusted a machine to speak to customers in their name. That is what SaiHey changes, safely and on-brand, and it is the shape of what becomes possible when sales expertise and agent infrastructure are built together.
