Sync qualified leads to HubSpot
SiliForm's HubSpot integration upserts contacts and sets properties from form answers in real time. Your sales team works from a contact record that already has the qualification data, not a raw form submission dump.

Drop-off analytics show which question kills completion on your lead gen forms. Fix the friction point, retest, and watch the conversion rate move — without guessing.

Questions teams ask
Does SiliForm capture UTM parameters?
Yes. SiliForm automatically reads UTM parameters from the URL when a respondent opens the form and attaches them to the submission. You can see source, medium, campaign, term, and content per response in your analytics dashboard.
How does the HubSpot integration work?
When a form is submitted, SiliForm looks up the contact by email in HubSpot and updates their properties, or creates a new contact if one does not exist. You map form fields to HubSpot contact properties in your form settings.
Can I use SiliForm for gated content forms?
Yes. A common setup is a short qualification form (2-4 questions) before a content download link is shown. SiliForm's conditional logic can route different download links based on what the respondent answers.
