One AI Layer Behind WhatsApp and Voice

An AI layer that lets Fundly's fintech customers get answers and take actions over WhatsApp and voice — and frees relationship managers from routine conversations to focus on what actually needs a human.

The Challenge

A hardcoded bot that broke the moment customers went off-script

Fundly's engagement team handled a large volume of similar conversations — product questions, status checks, onboarding help, reminders and follow-ups. The first WhatsApp bot was hardcoded, with fixed menus, keyword rules and scripted replies. It broke when customers used their own words, mixed languages, or changed topic, and every new use case meant new code. Voice had no automation at all, so every call needed a person.

What We Built

An agentic conversation platform, in three parts

Agentic WhatsApp Bot

Refactored from a hardcoded, menu-driven bot into an agent that reads the message, plans the next step, uses tools to fetch or update information, and keeps context.

Voice Agent

Designed and built from scratch — a real-time agent that answers calls, understands speech, responds naturally, and completes the same tasks as the WhatsApp agent.

Shared AI Platform

Agent orchestration (fundly-ai-spine), an MCP data and tool server (fundly_mart_mcp), and the RM-facing AI service (fundly-ai-rm) — one layer behind every channel.

Problems it solves

Rigid conversations

The agent interprets free-form messages and decides the next step, instead of matching fixed keywords.

Slow to extend

New abilities are added as tools, not new hardcoded menu branches.

No voice automation

The voice agent handles calls end to end and hands off when needed.

Scattered data

One MCP layer gives consistent, governed access across systems.

RM time on routine work

Routine queries are automated; RMs get AI support where it matters.

Limited availability

Instant responses on WhatsApp and voice at any hour.

A typical conversation

  1. 1Customer reaches out on WhatsApp or by phone
  2. 2Agent understands intent and pulls relevant history
  3. 3It plans next steps and calls the right tools via MCP
  4. 4It replies as text or speech, grounded in systems of record
  5. 5Sensitive or unresolved cases go to an RM with full context
  6. 6Every conversation is logged so quality can be reviewed

Trust and safety

  • Grounded answers from systems of record, not from the model's memory
  • Human handover for anything sensitive, high-value, or unresolved
  • Logged conversations and tool calls for review
  • Access controlled by the MCP data layer

Status: the WhatsApp bot has been refactored into an agentic system, and the voice agent is built from scratch with core conversational capabilities. Use-case coverage, voice languages, usage numbers and roadmap are still being confirmed.
