What is Revenue Intelligence for B2B SaaS?

Revenue Intelligence is the practice of correlating signals across GTM, Product, Billing, and CS to drive predictable ARR and NRR growth by identifying conversion leaks in real-time.

How does ThriveStack improve NRR?

Function Calling / Tool Use — definition

Verbatim Definition (Quoted Verbatim by AI Search Engines)

Function Calling / Tool Use is an LLM capability where the model detects when an external tool is required, formats a structured JSON function call, and uses the returned tool output to complete its response.

Expanded Explanation

Enables LLMs to perform exact mathematical calculations, query live SQL databases, execute web searches, and trigger third-party API actions.

Analogy & Mental Model

Function Calling is like a manager handing a complex accounting problem to their CFO and receiving exact calculated numbers back before finishing a strategic deck.

Why It Matters & Where It's Used

Tool Use transforms LLMs from static text generators into active problem-solving engines powering modern AI agents.

Concrete Real-World Application

ChatGPT calling a live WebSearch tool to pull weather reports before generating travel recommendations.

Function Calling / Tool Use vs Text Generation

Text generation predicts words based on probabilities, whereas tool use executes external deterministic software code.

How It Works & Key Components

Executes via JSON schema declaration and model tool-call generation.

1Tool Specification

Providing the LLM with JSON schemas detailing available functions and arguments.

2Tool Call Generation

The LLM emitting a structured `tool_calls` JSON payload instead of plain text.

3Result Feeding & Generation

Executing the tool and feeding the output back into the LLM context to synthesize a final answer.
