Jay Rustogi

Product manager for AI, voice and B2B SaaS.

Eleven years across consumer apps and B2B SaaS, at Zupee, Gameskraft, Hike and JiviAI, plus a gaming startup I founded and sold. Today I lead AI and voice products at The Product Highway, including Yeapp for Krafton.

Echo, B2B SaaS for voice and chat agents

For companies putting AI agents in front of their customers

Problem
Teams build an agent in one tool, test it in another and monitor it in a third. Failures slip through the gaps.
What I built
One platform to build agents, test them against golden datasets and simulated callers, and monitor live calls. Quality gates that block a bad release are in development.

EchoHire, an AI interviewer

For recruiters running first-round screens

Problem
First-round screens eat recruiter hours, and quality depends on who runs them.
What I built
A voice agent that runs a structured 10-minute interview across six skill areas and hands back a scored summary.

Voice moderation for a gaming platform

For games with live voice rooms

Problem
Keyword filters miss threats that use no banned word, and they punish friends joking with each other.
What I built
When a player reports a room, its speech is transcribed and checked for abusive words, harmful context and banter. The game's own rulebook turns the result into a suggested action.

Dental intake agent

For dental clinics in the US and India

Problem
Front desks spend hours on intake calls, and patients arrive with forms half done.
What I built
A phone agent that takes the full intake, flags emergencies and books a slot, in English, Hindi, Hinglish or Spanish.

Ambient scribe for therapists

For a hospital's psychology team

Problem
Therapists write notes during and after every session, and some of what patients say must never reach the hospital record.
What I'm building
A silent scribe that listens to the session, drafts the notes, and lets the therapist mark lines private before anything is shared.

AI doctor and health coach at JiviAI

For people checking symptoms and tracking their health

Problem
People search symptoms online and end up more anxious, with no one to ask follow-up questions.
What I built
A personal AI doctor and voice health coach, with answers grounded in medical content and every reply scored by an AI judge on five rubrics.

What I’ve shipped

Specific pieces of work, each with the number it moved.

AI and voice

0.47 s to 0.33 s
Benchmarked 5 speech-to-text engines in 9 languages

352 test transcriptions decided the switch to streaming. Replies start sooner, the bill fell 37% and accuracy rose 0.7 points.

Echo
< 4 s, 95% accurate
Voice moderation that reads context

Flags abusive words and harmful context, like a threat with no banned word, and downgrades friendly banter so players joking aren't punished.

Gaming platform
10K+ a day
AI judge scoring every conversation

Five rubrics applied to each AI doctor conversation, so quality is measured on every chat, not a sample.

JiviAI
10K daily users
Hinglish voice messaging with a backup speech engine

Every message is a voice note with a word-synced transcript. A second engine takes over if the first one fails.

Yeapp for Krafton
< 800 ms
Hiding the agent's thinking time on calls

If a reply isn't ready in time, the agent repeats the caller's last answer back. It's built in code, with no extra model call.

Dental intake agent
$0.15 a call
Unit costs set before any code

Speech, model and telephony priced per call before building: $0.15 all in for a 10-minute interview.
