◆ CASE STUDY · 12 — MULTICHANNEL AGENT
One thread. Three channels.
An AI agent that picks up an email, finishes it on SMS, and closes the deal over a phone call — without losing context. Identity-aware, voice-first, human one click away.

— 01 / THE HAND-OFF
Same conversation. Different channel.
Customers don't pick a channel and stay. Our agent picks up wherever they last left off — with full memory of the thread.

Yes — interested. Can you ping me here? Easier than email.
Of course, Priya. Pricing depends on volume — what's your current monthly?
~ 8k API calls/day.
At that scale we're ~40% under your current provider. Want me to call and walk through it?

"What's the catch?"
"No annual lock-in. Cancel monthly. Same SLA."
"OK. Send me the contract."

— 02 / IDENTITY STITCHING
One person. Many touchpoints.
Email address. Phone number. Browser cookie. Postgres stitches them into a single conversation thread — so the agent never re-introduces itself.
