HubSpot Product Update: Knowledge Vaults Now Support Custom Objects

In an era where AI solutions like Breeze AI play a pivotal role in HubSpot, many business owners face a common frustration: "Why can’t AI answer specific questions about my unique business?"

For instance, if you run a car dealership, the AI might recognize a contact (the customer) but have no clue which cars are currently in stock. Or, if you manage a pet hotel, the AI might remember the owner’s name but fail to track a specific dog’s food allergies.

These limitations are becoming a thing of the past. HubSpot has now enabled the connection of Custom Objects to Knowledge Vaults. This allows your proprietary business data—beyond the standard CRM fields—to be fully utilized by AI Agents such as Breeze or Custom Assistants, transforming AI into an "Intelligent Specialist" with deep institutional knowledge.

What are Knowledge Vaults, and Why are Custom Objects the Missing Piece?

To understand the impact, we must first look at how Knowledge Vaults function. They act as the centralized "brain" for AI Agents, pulling data from various sources like Knowledge Bases or the CRM to answer queries. Previously, however, they were restricted to Standard Objects (e.g., Contacts, Companies, or Deals).

In reality, most businesses rely on data that doesn't fit into standard categories. Critical information is often stored in Custom Objects, such as inventory lists, booking histories, machinery specifications, or shipment details. Until now, AI was blind to this data.

This update means the specialized data structures you’ve built in HubSpot can now flow directly into Knowledge Vaults.

A Major Shift: Knowledge Vaults + Custom Objects

This HubSpot feature allows you to:

Connect Segments created from Custom Objects to Knowledge Vaults.
Sync all data, including Records, Properties, and Associations.
Receive Real-Time updates whenever data changes.
Enable AI Agents to use this information to provide immediate, accurate answers.

Simply put, your AI is no longer limited to basic CRM data; it now understands the actual structure of your business operations.

Say Goodbye to Data "Blind Spots"

Imagine if your AI Agent worked like a veteran employee with 10 years of experience. Consider the efficiency gains:

From Generic to Granular: Previously, AI could only give broad answers like "We offer maintenance services." Now, it can answer specifically: "We have 5 units of Spare Part ABC in stock and can schedule your repair immediately," because it has access to your Inventory Custom Object.
Hyper-Personalization: By analyzing Associations (how different data points relate to one another), AI can understand individual customer behaviors and provide highly tailored solutions.
Real-Time Execution: AI stays updated through Knowledge Vaults the moment a status changes in a Custom Object (e.g., a shipping update), eliminating the need to wait for overnight sync cycles.

How It Works: A Deep Dive

Connecting Custom Objects to Knowledge Vaults is a seamless process:

1. Connecting Custom Objects Instead of pulling in unorganized data, HubSpot lets you connect via Segments created from Custom Objects. This allows you to curate exactly what the AI learns—for example, only syncing products currently "In Stock" or orders marked as "In Progress."

In Knowledge Vault settings, select “Custom Object Segments” as a data source.
Choose the desired Segment from the list.
The data will begin syncing to the Vault.

2. Comprehensive Data Syncing Once a Segment is selected, the system pulls in:

Records: Every individual data entry.
Properties: The specific details and attributes.
Associations: The vital relationships between different data types.

3. Real-Time Updates Information remains current. Any change to a Record or Property is reflected instantly, ensuring your AI is always as smart as your most recent data.

Knowledge Vaults Are Levelling Up

The integration of Knowledge Vaults and Custom Objects breaks down the wall between back-office data and front-end customer experience.

If you have invested heavily in building Custom Objects, now is the time to reap the rewards. Your AI is no longer just a chatbot; it is a Business Expert capable of closing sales and solving complex problems with professional-grade accuracy—without you ever having to manually feed it the same information twice.
