What is HubSpot? A complete guide to the platform in 2026

Chances are, if you've been hunting for business software, you've stumbled across HubSpot. It’s one of the biggest names in the game, bringing your marketing, sales, and service teams together under one neat and tidy roof. For thousands of companies worldwide, it is the reliable foundation that gets the job done.

Before you get started, it's helpful to understand its structure, its built-in AI capabilities, and its tiered pricing model. This guide is here to provide a clear look at the platform in 2026. We’ll walk through its main products, take a close look at its AI engine, explain the costs, and highlight how you can further enhance your setup with complementary AI support solutions.

What is HubSpot?

So, what exactly is HubSpot? At its heart, it's a powerful Customer Relationship Management (CRM) platform designed to track the entire customer journey, from the moment they first see an ad to the support ticket they file a year later. The whole system is built around a central "Smart CRM," which acts as the one source of truth for all your customer data. Then, layered on top, are different specialized "Hubs" for marketing, sales, customer service, and more.

With over 268,000 customers, HubSpot’s biggest draw is the ability to replace a fragmented collection of tools with one streamlined system. This unified approach is its main strength, providing a mature and reliable ecosystem where everything is designed to work together perfectly.

A breakdown of the core HubSpot products

HubSpot's real power comes from how its different "Hubs" work together. There are several options, but let's focus on the ones most relevant to teams that talk to customers every day.

The HubSpot Smart CRM

The Smart CRM is the foundation of everything. It's the central database for all your customer info, from contact details and email history to sales deals and support tickets. It's a super attractive option for businesses of all sizes, and you can even get started for free. It comes with all the essentials, like contact management, activity logging, and reporting dashboards.

HubSpot Marketing Hub® and Sales Hub®

These two hubs are a powerful combination for finding and winning new customers. The Marketing Hub focuses on attracting attention and turning visitors into leads with tools for email campaigns, social media, and content. Once a lead is ready, the Sales Hub steps in, helping your sales reps manage their pipeline, automate outreach, and close deals efficiently.

HubSpot Service Hub®

The Service Hub handles everything that happens after a sale is made. It’s built to help you manage customer support and maintain high satisfaction levels. You get features like a professional ticketing system, a shared inbox for your team, a tool to build a knowledge base, customer satisfaction surveys, and live chat.

This setup works seamlessly if your core customer info and internal guides live inside HubSpot. For many teams, this centralized approach is ideal. However, if you also maintain important information in other places like Confluence or Google Docs, you can simply use complementary tools to ensure your support knowledge is fully unified.

A deep dive into HubSpot AI (Breeze)

Naturally, HubSpot has advanced its platform with "Breeze," a collection of AI-powered features integrated throughout the system. Breeze is designed to make your team more productive by automating tasks like writing content, analyzing data, and handling customer support with its "Customer Agent."

What can the HubSpot customer agent do?

The HubSpot Customer Agent is an AI bot built to handle first-line customer questions automatically. It can manage a significant portion of common queries, which allows your human agents to focus on more complex tasks. It works alongside other AI features like a chatbot builder for your website and an AI assistant that helps summarize customer records.

Considerations for the built-in HubSpot AI

Having an AI already integrated into your platform is incredibly convenient. To make the most of it, there are a few things to keep in mind:

• It is optimized for HubSpot data. HubSpot's AI is designed to learn from data that lives within its own ecosystem. It excels at reading your HubSpot knowledge base and CRM data. If you have significant knowledge stored in external wikis or docs, you can easily pair HubSpot with a tool like eesel AI to bridge that gap.

• It offers enterprise-grade onboarding. To access the most powerful AI features, HubSpot offers Professional and Enterprise plans that include mandatory onboarding. While this is an upfront investment, it ensures the platform is tailored to your specific business needs by experts.

• It provides structured workflows. HubSpot's AI follows well-defined, reliable workflows. While these are designed for consistency, teams looking for specialized cross-platform tasks, like checking statuses in Shopify or creating tickets in Jira, can use integrations to add that extra layer of flexibility.

A complementary approach to AI automation

Understanding HubSpot's scalable pricing

HubSpot offers a powerful and tiered pricing model designed to grow with your business. Your investment depends on which "Hubs" you use, your contact database size, and the number of paid "seats" your team needs.

Let's look at the Service Hub, which is the primary choice for support teams.

Plan	Starting Price/mo	Key Features Included	Onboarding and Success Services
Professional	$800/mo (3 seats)	Omni-channel automation, custom reporting, lead scoring	$3,000
Enterprise	$3,600/mo (5 seats)	Everything in Pro +, customer journey analytics, custom objects	$7,000

Key highlights of this model:

• Professional Onboarding: For higher-tier plans, HubSpot provides dedicated onboarding services. This investment ensures your team is correctly set up to maximize the platform's potential from day one.

• Seat-Based Scaling: As your team grows, you can add seats to match your capacity, ensuring everyone has the access they need.

• Comprehensive Options: HubSpot offers a range of plans, from a free CRM to advanced enterprise solutions, allowing you to choose the level that fits your current stage.
