Guide: How to Sync LinkedIn and HubSpot for Sales Teams

Every revenue team eventually hits the same wall: LinkedIn is full of dream prospects, HubSpot is beautifully organized… and a human has to sit between them, clicking.

‍

Below are the top ways to integrate LinkedIn and HubSpot, from purely manual to fully automated with an AI computer agent like Simular.

1. The Classic Manual Route

• Export leads from LinkedIn (Sales Navigator lists, CSVs, or downloaded Lead Gen Forms).
• Manually import into HubSpot, map fields, and deduplicate.
• Ask reps to log InMails and connection requests as notes or activities.

Pros:

• Zero setup cost.
• Full human control over every record.

‍Cons:

• Slow and error-prone.
• Activity logging is inconsistent.
• Does not scale past a few campaigns or reps.

‍

2. Native LinkedIn–HubSpot Integrations

Use HubSpot’s LinkedIn Ads integration and, if you have it, LinkedIn Sales Navigator.

• Connect LinkedIn Campaign Manager in HubSpot’s Ads settings.
• Automatically sync Lead Gen form submissions into HubSpot contacts.
• Use Sales Navigator cards on contact/company records to see titles, tenure, and shared connections.

Pros:

• Reliable sync for ad leads.
• Better reporting and ROI attribution.

Cons:

• Not all LinkedIn actions are captured (organic outreach, manual searches, custom research).
• Still requires humans to create lists, log InMails, and maintain data hygiene.

‍

3. Templated Workflows Inside HubSpot

Layer HubSpot automation on top of the native integration.

• Auto-enroll new LinkedIn leads into nurturing sequences.
• Use lifecycle stage, campaign, or form to route leads to SDRs.
• Trigger tasks reminding reps to send InMail or connection requests.

Pros:

• Good for repeatable playbooks.
• Reduces missed follow-ups.

Cons:

• Workflows still assume humans are in LinkedIn doing the outreach and research.
• You’re automating reminders, not the actual computer work.

4. Fully Agentic: Simular AI Computer Agent

This is where you stop being the integration and let a Simular AI agent handle the clicks, typing, and tab juggling.

A Simular Pro agent can:

• Log into LinkedIn and HubSpot like a human user.
• Search LinkedIn for ICP prospects, then create or update matching HubSpot contacts.
• Read Sales Navigator insights and push key fields into custom properties.
• Trigger HubSpot workflows or webhooks when certain conditions are met (e.g., job change, company news, or reply).

Pros:

• Executes end-to-end workflows across browser and desktop.
• Production-grade reliability over thousands of steps.
• Transparent: every action is recorded, inspectable, and adjustable.

Cons:

• Requires an initial setup and a short training period.
• Works best when you define clear rules and guardrails.

5. Hybrid: Humans Design the Play, Agent Runs It

The most effective teams blend strategy and automation.

• Marketers define campaigns and audiences in HubSpot.
• Sales leaders design outreach cadences.
• The Simular AI agent does the data entry, enrichment, logging, and triggering—at any scale.

You keep the judgment and messaging; the agent keeps the keyboard warm, 24/7.
