HubSpot’s marketplace offers over 1,870 apps and integrations designed to extend core functionality across sales, marketing, operations, and customer service ^[5]. These integrations connect HubSpot with popular tools like Gmail, Zoom, and Salesforce, while also providing niche solutions for automation, data management, and team collaboration. The marketplace categorizes apps by use case—such as workflow automation, analytics, and communication—with many available for free to reduce implementation barriers.

Key highlights from the available integrations:

• Most popular free apps: Gmail (415K installs), Google Calendar (246K installs), and Zapier (173K installs) dominate usage, enabling seamless email, scheduling, and multi-app automation ^[2][10].
• Native HubSpot-built apps: Includes Google Meet (58K installs), Salesforce sync (18K installs), and Slack (80K installs), ensuring deeper compatibility and support ^[4].
• Connector tools: Zapier (173K installs), Make (43K installs), and Workato (4K installs) enable no-code/low-code integrations with thousands of external platforms ^[6].
• Emerging trends: AI-powered tools and Chrome extensions (via HubSpot APIs) are expanding customization options, though development requires adherence to API rate limits and security protocols ^[8].

The marketplace emphasizes personalized recommendations and trending solutions like QuotaPath for sales prioritization and Snowflake for data activation ^[1][3]. Businesses of all sizes can leverage these integrations to reduce manual tasks, improve data accuracy, and scale operations—with selection criteria often including user reviews, ease of setup, and measurable ROI ^[5][7].

Extending HubSpot’s Core Functionality

Sales and Marketing Integrations

HubSpot’s sales and marketing integrations focus on streamlining lead management, enhancing customer insights, and automating outreach. These tools sync data bidirectionally with HubSpot’s CRM, reducing manual entry and improving campaign precision. The marketplace prioritizes solutions that integrate with existing workflows while adding layers of analytics or personalization.

Top-performing sales and marketing apps:

• LinkedIn Ads (79K installs): Provides cross-network reporting to track ad performance directly within HubSpot, enabling marketers to attribute revenue to specific campaigns ^[2]. The integration syncs lead data from LinkedIn forms, reducing the need for manual contact creation.
• Meta Ads (131K installs) and Google Ads (124K installs): Both offer ROI tracking and automated reporting, with Meta Ads focusing on social media lead gen and Google Ads on search/display network performance ^[2]. Users can view ad spend alongside HubSpot contact records for unified attribution.
• Mailchimp (41K installs): Syncs contact lists and email activity between platforms, allowing marketers to trigger HubSpot workflows based on Mailchimp campaign engagement ^[2][4]. This is particularly useful for businesses transitioning from Mailchimp to HubSpot’s native email tools.
• LinkedIn Sales Navigator: Enriches HubSpot CRM records with professional insights like job changes or company news, helping sales teams prioritize outreach ^[7]. The integration requires a Sales Navigator license but reduces research time by surfacing key details within contact profiles.
• Typeform (34K installs): Replaces static forms with interactive surveys or quizzes, embedding responses directly into HubSpot contact properties ^[2]. Businesses use this for lead qualification or customer feedback without manual data entry.

Implementation considerations:

• Ad integrations (Meta, Google, LinkedIn) require proper UTM parameter setup in HubSpot to ensure accurate attribution ^[5].
• Mailchimp’s sync operates on a 15-minute delay for contact updates, which may impact real-time workflows ^[4].
• Sales Navigator’s data enrichment is limited to LinkedIn’s public API, so custom fields may require manual mapping in HubSpot ^[7].

Workflow Automation and Data Management

Automation and data tools form the backbone of HubSpot’s extensibility, connecting disparate systems to eliminate silos. These integrations range from no-code connectors like Zapier to advanced ETL platforms for enterprise data warehouses. The marketplace highlights solutions that reduce repetitive tasks while maintaining data integrity across platforms.

Critical automation and data apps:

• Zapier (173K installs): The most widely used connector, enabling automation between HubSpot and over 7,000 apps without coding ^[2][6]. Common use cases include:
• Creating HubSpot contacts from Typeform submissions.
• Updating Slack channels when deals reach specific stages.
• Syncing HubSpot tasks with Trello or Asana boards.

Limits include a 15-minute delay for free plans and a 100-task/month cap unless upgraded ^[6].

• Make (formerly Integromat) (43K installs): Offers more complex scenario-building than Zapier, with visual workflow designers for multi-step automations ^[6]. Users report faster execution times for high-volume data syncs, such as e-commerce order processing.
• Workato (4K installs): Targets enterprise users with advanced error handling and governance features, supporting HubSpot integrations with NetSuite, Workday, or custom APIs ^[6]. Requires technical setup but reduces IT dependency for ongoing maintenance.
• Skyvia (3K installs): Provides no-code ETL (Extract, Transform, Load) for HubSpot data, enabling two-way syncs with databases like MySQL or cloud apps like QuickBooks ^[6]. Useful for businesses migrating legacy data into HubSpot.
• Google Sheets Connector (5K installs): Allows bidirectional syncs between HubSpot and spreadsheets, enabling teams to manage contacts or deals in familiar interfaces ^[6]. Popular for event attendee lists or inventory tracking, though large datasets may hit API rate limits.
• Snowflake: A newer addition for data activation, enabling HubSpot users to push CRM data into Snowflake’s cloud data warehouse for advanced analytics ^[1][3]. Requires SQL knowledge but unlocks predictive modeling capabilities.

Data management challenges:

• Connector apps like Zapier or Make may duplicate contacts if workflows lack deduplication rules ^[5].
• Real-time syncs are rare; most tools update in batches (e.g., every 15–60 minutes), which can delay time-sensitive actions ^[6].
• Custom API integrations (e.g., via Tray.io or Pipedream) offer flexibility but require developer resources for setup and maintenance ^[6][8].

Emerging trends in automation:

• AI-powered tools: HubSpot’s marketplace now features AI-driven apps for tasks like email response suggestions or deal scoring, though specific examples aren’t detailed in the sources ^[3].
• Chrome extensions: Developers can build custom extensions using HubSpot’s API to surface CRM data in browsers (e.g., LinkedIn profiles) or add context-specific actions ^[8]. Authentication requires OAuth 2.0, and public apps must undergo HubSpot’s review process.
• Two-way syncs: Tools like Unito (2K installs) enable bidirectional updates between HubSpot and project management platforms (e.g., Trello, Asana), reducing manual status updates ^[6]. However, sync conflicts can occur if teams edit records in both systems simultaneously.
