Investment Satisfaction Surveys

Gather structured feedback from investment clients on advisor performance, portfolio satisfaction, and likelihood to recommend — with branching follow-ups.

Why this matters

PCI-compliant, fully auditable voice automation for loans, collections, onboarding, and fraud prevention. This example shows you how to automate investment satisfaction surveys calls end-to-end with Guava's SDK — no telephony plumbing, no prompt engineering, just Python.

Step 01

Installation

Install from Guava's private PyPI index. A public package is coming soon — the install command will simplify to pip install guava.

terminal
# Step 1: Install Guava
pip install gridspace-guava --extra-index-url https://guava-pypi.gridspace.com

# Public PyPI package coming soon — the install command will simplify to:
# pip install guava

# Step 2: Set your credentials
export GUAVA_API_KEY="..."
export GUAVA_AGENT_NUMBER="..."
Step 02

How it's built

Every Guava agent is a Python class. Walk through the key sections below, then grab the complete file at the end.

01

Imports

Import the Guava SDK and any helpers you need. guava.CallController is the base class for every voice agent.

example.py
# Install: pip install gridspace-guava --extra-index-url https://guava-pypi.gridspace.com
import guava
import os

Agent setup

set_persona() defines how the agent presents itself. set_task() gives it its mission in plain English. The checklist drives the conversation — Guava works through it top-to-bottom, collecting Field values and speaking Say items as it goes.

example.py
class InvestmentSurveyBot(guava.CallController):
    def __init__(self, client_name: str, advisor_name: str):
        super().__init__()
        self.set_persona(
            organization_name="Vantage Wealth Management",
            agent_name="Jordan",
        )
        self.set_task(
            objective=f"Conduct a satisfaction survey with {client_name} about their experience with advisor {advisor_name}",
            checklist=[
                f"Introduce yourself and explain this is a brief satisfaction survey — estimated 2 minutes.",
                guava.Field(
                    key="overall_satisfaction",
                    field_type="rating",
                    description="Overall satisfaction with wealth management services (1-10)",
                ),
                guava.Field(
                    key="advisor_satisfaction",
                    field_type="rating",
                    description=f"Satisfaction with advisor {advisor_name} specifically (1-10)",
                ),
                guava.Field(
                    key="nps_score",
                    field_type="rating",
                    description="How likely to recommend Vantage to a friend or colleague (0-10)",
                ),
                guava.Field(
                    key="improvement_feedback",
                    field_type="text",
                    description="One thing the client would most like to see improved",
                    required=False,
                ),
                guava.Field(
                    key="ok_to_contact",
                    field_type="bool",
                    description="Can an advisor follow up on this feedback?",
                ),
                "Thank the client for their time.",
            ],
            on_complete=lambda fields: print(f"Survey complete: {client_name} NPS={fields.get('nps_score')}"),
        )

    controller=InvestmentSurveyBot,
