Top 10 HubSpot Integrations for Scaling Businesses in 2025

Introduction

Growing a business can be exciting, but it comes with its fair share of growing pains. As your business evolves, processes change, and the tools that once worked quickly become bottlenecks. Communication starts to slip, leads fall through the cracks, and teams end up working in silos. That’s when many companies turn to HubSpot, not just for its CRM, but for the entire ecosystem it offers.

HubSpot works best when paired with the right integrations. The platform is evolving rapidly, with the introduction of AI features like its Breeze AI-powered agents and ChatGPT deep research integration, designed to help your teams work faster, analyse data smarter, and make better decisions.

In this post, we’re taking a closer look at the ten best HubSpot integrations 2025 that can genuinely support scaling businesses, tools that reduce manual work, improve data visibility, and ultimately help you grow more efficiently.

Let’s begin with one that’s helping sales teams work smarter from day one.

1. Cognism. Smarter Lead Enrichment for B2B Growth

When you’re growing quickly, every minute your team spends chasing the wrong leads is time and money lost. That’s why tools like Cognism are so valuable for sales-focused businesses. It plugs straight into HubSpot and enriches your contact records with accurate, GDPR-compliant B2B data, so your team always knows who they’re talking to.

Why it’s useful

Cognism doesn’t just add more names to your database. It gives you richer information on the people and companies you’re already in touch with — like direct dials, job titles and company size — making it easier to prioritise high-value prospects. This is especially helpful for outbound sales teams looking to streamline their outreach.

A more intelligent workflow

Cognism’s filtering and intent data work well alongside HubSpot’s built-in AI features, which can now score leads, suggest next actions, and even help write personalised follow-up emails through the new ChatGPT integration. Together, they give sales teams the context they need to work more efficiently, with less guesswork.

No guesswork, just better focus

For businesses trying to scale, it’s all about focus. Integrating Cognism with HubSpot helps sales teams spend more time having meaningful conversations and less time on manual research.

2. Salesforce – Cross-CRM Synchronisation for Hybrid Enterprise Teams

For many growing businesses, especially those that have evolved through acquisitions or departmental tool choices, Salesforce remains somewhere in the tech stack. While some teams may have fully embraced HubSpot, others—often the sales or customer success teams—are still working inside Salesforce. The good news is, HubSpot’s native Salesforce integration makes it easy to keep both platforms in sync.

When two systems don’t talk, people stop talking too

As businesses scale, one of the biggest challenges is data fragmentation. Marketing might be capturing great leads in HubSpot, but if those leads aren’t syncing properly with the sales team’s system, things fall apart. Opportunities are missed, reporting becomes inconsistent, and everyone spends more time checking data than using it.

The Salesforce–HubSpot integration solves this by syncing contacts, companies, and deal records across platforms in real-time. That means both marketing and sales can work in the systems they know best, without stepping on each other’s toes.

More alignment, less admin

This integration is particularly valuable for leadership teams trying to get a clearer view of the full funnel. With data flowing both ways, marketers can finally see how their campaigns translate into closed deals, and sales teams gain better visibility into lead sources and behaviour before a conversation even begins.

Built to scale

As your team grows, the need for clean, accurate, and timely data grows with it. HubSpot’s Salesforce integration is designed to scale with your operations. Whether you’re onboarding new reps, testing a new lead scoring model, or rolling out AI-based lead routing, a stable data bridge between platforms is essential.

3. Slack – Real-Time Team Collaboration That Keeps Everyone Aligned

Scaling a business means faster decisions, tighter timelines and more people to keep in the loop. When teams grow, the cracks often start to show in communication. That’s where integrating Slack with HubSpot can make a real difference.

Slack isn’t just for internal chat. When connected with HubSpot, it becomes a powerful notification and collaboration tool that helps teams stay aligned, without relying on endless email threads or unnecessary meetings.

Bring deal updates straight to your team

With the integration in place, you can set up alerts to notify relevant Slack channels whenever something important happens in HubSpot. That might be a new lead submission, a deal moving to a new stage or a support ticket being created. This keeps sales, marketing and service teams informed and ready to act in real time.

Collaborate where your team already works

Rather than switching between tools, your team can comment on updates, tag colleagues and ask for support—all without leaving Slack. For scaling businesses where speed is critical, this kind of seamless workflow helps reduce response times and keeps momentum high.

Make onboarding smoother

Slack notifications are also helpful for onboarding new team members. Instead of waiting to learn about how deals progress or how marketing campaigns perform, they can follow the live feed in Slack and see the process in action from day one.

Room for automation

You can even take things a step further with workflow automation. For example, HubSpot’s Workflows tool can trigger custom Slack messages when deals hit certain criteria, like notifying a manager if a deal over £50,000 moves to ‘negotiation’. These smart nudges can save time and help you stay on top of key moments as your pipeline grows.

4. Zapier – Multi-App Automation Made Easy

One of the biggest challenges for growing businesses is managing a growing number of tools. You might have HubSpot at the centre, but there’s probably also an invoicing platform, a project management system, perhaps a customer support tool—and they don’t always speak the same language. That’s where Zapier steps in.

Zapier acts as the glue between your apps. It allows you to create automated workflows (called “Zaps”) between HubSpot and thousands of other platforms, without needing to write a single line of code.

Save time on repetitive tasks

Scaling often means more admin, especially if your team is manually copying data between systems. With Zapier, you can automate those tasks. For example, you might automatically create a new Trello card or Slack message every time a deal is won in HubSpot. Or log customer support tickets from HubSpot form submissions straight into Zendesk.

Make your stack work harder

Zapier helps you get more value from the tools you already use. By creating connections between them, you reduce the need for duplicate data entry and manual follow-ups. That means fewer mistakes and more time for high-impact work.

Accessible automation for growing teams

What’s great about Zapier is how accessible it is. You don’t need a developer or technical lead to set it up. Most Zaps can be built in minutes using simple logic—if this happens in HubSpot, then do that in another tool. And as your processes evolve, you can easily adjust your automations to match.

Built for scale, not complexity

As your team grows, so do your needs. Zapier gives you the flexibility to build lightweight automations that scale alongside your operations, without the need to invest in heavy custom integrations or complex development projects.

5. ZoomInfo – Deep Market Intelligence to Fuel Smarter Outreach

When a business is scaling, it’s not just about finding more leads; it’s about finding the right ones. That’s where ZoomInfo comes into play. As a powerful data intelligence platform, ZoomInfo integrates with HubSpot to provide access to rich B2B contact and company data that helps you build better-targeted prospect lists and more relevant campaigns.

Know more before the first contact

With ZoomInfo plugged into HubSpot, your sales and marketing teams gain deeper insights into potential customers. This includes firmographic data like company size and industry, as well as technographic data (what software they’re already using) and intent signals that reveal buying behaviour. Having this kind of context directly inside HubSpot helps teams prioritise high-potential leads and tailor their approach from the start.

Better data, better segmentation

One of the biggest strengths of ZoomInfo is the ability to build segmented lists based on highly specific criteria. That might mean targeting decision-makers in fintech companies with over 100 employees, or accounts currently researching CRM platforms. This data feeds directly into your HubSpot campaigns, allowing for much more personalised, relevant outreach.

How it compares to other tools

You might be wondering how ZoomInfo stacks up against something like Cognism. The answer largely comes down to geography and industry focus. Cognism tends to be stronger in European markets, while ZoomInfo has more traction in North America. Both offer powerful enrichment, but ZoomInfo stands out for its vast company intelligence and intent tracking features, which can be particularly useful for account-based marketing.

AI-powered insights that scale

With HubSpot’s AI features evolving, ZoomInfo’s integration is becoming even more useful. The insights it provides can now help train lead scoring models and trigger automated nurture journeys through HubSpot’s AI assistant. It’s a smart way to let data guide your decisions, rather than relying on guesswork.

6. Mailchimp – Scalable Email Marketing Campaigns

Email marketing still plays a massive role in nurturing leads and driving conversions, especially for growing businesses. If your team is already using Mailchimp and looking to connect it with HubSpot, the integration makes it easy to create coordinated campaigns without duplicating work.

Sync your audience effortlessly

With the integration in place, your Mailchimp audience can be automatically synced with contact lists in HubSpot. That means your email lists stay clean and up to date without needing manual exports. It’s a huge time-saver and ensures that new leads from HubSpot forms are added directly to the right Mailchimp workflows.

Track performance across platforms

Once connected, HubSpot gives you visibility into how contacts are interacting with your Mailchimp campaigns—opens, clicks, unsubscribes and more. This data can feed into your lead scoring, so your sales team knows who’s engaged and ready for a conversation.

Best for startups and content-driven teams

If you’re a startup or a small business scaling through newsletters, webinars or content campaigns, Mailchimp’s design tools and automation features work well. It’s simple, effective and keeps your messaging consistent as you grow.

7. LinkedIn Sales Navigator – Smarter Social Selling for businesses

LinkedIn is a goldmine for B2B outreach, and Sales Navigator takes it to the next level. When connected, this is the perfect HubSpot integration for lead generation, which gives your sales team more visibility and context when engaging with leads on LinkedIn.

Enriched profiles within HubSpot

You can view LinkedIn profile data right inside HubSpot contact records, including mutual connections, shared interests and job changes. This makes it easier to personalise your outreach and build rapport with potential customers.

InMail and activity tracking

The integration also allows you to send InMails directly and log LinkedIn activity to HubSpot, helping sales teams keep a full record of engagement across platforms.

A must-have for outbound strategies

For businesses relying on outbound, social selling is often more effective than cold calls or email alone. Sales Navigator helps your team identify and build relationships with key decision-makers, making it easier to land meetings and move deals forward.

8. PandaDoc – Streamlined Document Workflows

As your sales process matures, creating and managing documents like proposals, quotes, and contracts becomes more time-consuming. PandaDoc removes that friction by connecting document creation directly with HubSpot data.

Faster deal turnaround

Sales reps can pull data straight from HubSpot into PandaDoc templates—no copying and pasting required. That means fewer errors and a much faster turnaround time on proposals and contracts.

Track engagement

You’ll also be able to see when a document is opened, commented on or signed. This is useful for knowing when to follow up and helps keep deals moving through the pipeline.

Ideal for scaling sales teams

If your team is sending out multiple proposals a day, PandaDoc cuts down the admin and keeps everything consistent. It’s especially helpful when onboarding new sales reps who need to hit the ground running.

9. Typeform – Smarter Data Collection

Typeform offers an easy way to collect data through beautifully designed forms, surveys and quizzes—and it integrates seamlessly with HubSpot.

Better engagement, better data

Whether you’re collecting lead details, running a customer satisfaction survey or qualifying prospects with interactive forms, Typeform’s user-friendly design helps increase completion rates. Once submitted, the data flows straight into HubSpot.

Great for lead qualification

Many businesses use Typeform to qualify leads before they even speak to a sales rep. By scoring responses and triggering workflows in HubSpot, your team can follow up faster and more effectively.

Perfect for scaling with a personal touch

As you grow, it’s easy to lose the human side of your brand. Typeform helps maintain that personalised feel, even as you automate more of your lead capture process.

10. Gong – AI-Powered Revenue Intelligence

Gong offers conversation analytics and sales intelligence that helps teams understand what’s working in their calls and demos, and what isn’t.

Real-time insights, right in HubSpot

With the Gong integration, call recordings, transcripts and insights are automatically logged to HubSpot records. Managers can quickly review calls, identify common objections and coach reps based on real conversations.

Support for data-driven decision making

As HubSpot rolls out more AI capabilities, Gong adds another layer by surfacing trends, forecasting deal success and highlighting at-risk accounts. This information is incredibly valuable for leaders looking to make informed decisions without relying solely on instinct.

Coaching at scale

For growing teams, Gong makes it easier to maintain consistency and upskill new reps. You can identify top-performing behaviours and replicate them across the team, helping everyone hit their targets more consistently.

Bonus: HubSpot App Marketplace – Always Evolving

HubSpot’s App Marketplace is growing fast, with over 1,500 integrations available. From AI content assistants to niche industry tools, there’s always something new to explore. One recent standout is HubSpot’s native integration with ChatGPT, which is powering smarter automation, content creation and customer service across the platform.

Emerging integrations to watch

As AI becomes more embedded into day-to-day operations, expect to see more tools offering predictive analytics, intelligent routing and real-time optimisation, all designed to work directly within HubSpot.

Tailored integrations for niche needs

For businesses with unique workflows, custom-built apps using HubSpot’s API can offer the flexibility needed to scale without compromising on process.

Choosing the Right Integrations for Your Growth Stage

Not every HubSpot integration will be right for your business, and that’s okay. The key is choosing tools that match your stage of growth, and sales and marketing automation tools that match your team’s needs and your long-term goals.

For startups and early-stage companies, tools like Mailchimp, Typeform and Slack help build momentum without overcomplicating things.

For scale-ups and mid-market teams, integrations like Cognism, Salesforce and Gong support more advanced processes, data sharing and performance insights.

For enterprise-level businesses, automation and data intelligence through ZoomInfo, PandaDoc and ChatGPT-powered features can drive serious efficiency at scale.

How to Implement These HubSpot Integrations Effectively

Implementing HubSpot CRM scaling tools doesn’t have to be complicated. Most of the integrations we’ve covered can be set up directly from HubSpot’s App Marketplace with just a few clicks. However, for more complex tools like Salesforce or Gong, a bit of planning goes a long way.

Map your workflows before integrating

Set clear goals for what success looks like

Train your team on how and when to use the new tools

Review and optimise regularly

You don’t need to do it all at once. Start with one or two integrations that solve the biggest pain points, then expand as your team gets more comfortable.

Conclusion

HubSpot is a powerful platform on its own, but it becomes truly transformational when paired with the right integrations.
