Today’s Topic

How to maximize the value of
combining SaaS with Claude

Combining Claude with a business system such as Salesforce opens up enormous possibilities. But the benefits appear only when the underlying data structure is something AI can understand.

Start with Claude Code to create
a data structure AI can work with.

What’s Happening Now

AI adoption is accelerating.
But the answers still fall short.

The problem is not that AI is not smart enough.
The information it needs is not organized.

Our Story

For 12 years since 2013,
Salesforce has grown at the heart of our operations.

At the Leave a Nest Group, we centralized sales, research, and education data in Salesforce and made it the foundation of our operations.

The more successful a business system becomes, the more complex it grows over time.

The Structural Problem

Business systems become more complex as they grow

At launch After years of use 12 years Workflows fit the standard features Anyone can see where everything belongs Every addition creates more custom data and integrations Eventually, no one sees the whole picture
12 Years of Results · Our Actual Data

Our custom data objects accumulated to 135

50 100 2014 2015 2016 2017 2018 2019 2020 2021 2022 2023 2024 2025 28 added in 2017 alone New development to support business growth 135 objects 115 objects in the first 7 years +20 over the next 5 years (growth slowed)
Added that year Prior cumulative total * Company-specific data containers called “custom objects” in Salesforce
The Turning Point

AI agents suddenly made the problem impossible to ignore

People

  • Experience tells them which information matters
  • Tacit knowledge fills in duplicates and exceptions

AI agents

  • They process large volumes of information as-is
  • Multiple similar datasets create ambiguity
  • Irrelevant data can become part of the evidence

A system held together by human tacit knowledge is unreadable to AI.

Our Choice

Project Vanilla Core

In software, “vanilla” means the unaltered standard state.

Before adding more AI,
return the business platform to a state AI can understand.

This is reform by subtraction, not addition. A simple structure built on standard features gives AI agents the foundation they need to perform.

How We Make It Happen

Claude Code × MCP, CLI, and APIs: untangling 12 years of complexity

Claude CodeAnalyze, plan, and implement
Connected through three paths
MCPA protocol connecting AI and systems
CLICommand-line tools
APIInterfaces for system integration
Read data and apply changes
Metadata (design information)
Business data

With access to both metadata and business data,
we can move continuously from understanding the AS-IS to implementing the TO-BE.

What Actually Changed

Improvements postponed for lack of time finally started moving

Before

  • We knew what needed improvement
  • Investigation alone took enormous time
  • So the work stayed on the backlog

After

  • Claude Code supports analysis and execution
  • Multiple improvements move forward in parallel
  • A continuous improvement cycle emerges

The value of generative AI is not merely saving time.
It is scaling improvements that were previously impossible.

In Your Organization

This is not just a Salesforce story

The longer a system has been used and expanded,
the more it needs to be organized for the AI era.

Closing Message

Before making AI smarter,
create a business environment
AI can understand.

Preparing for the AI era is not only about building new systems. It also means returning the systems we have nurtured to a state AI can understand. Claude Code is a powerful partner for that work.
