What Is Contrast? Webinars Built Around HubSpot

The short answer: if HubSpot is where your marketing lives and a webinar draws a few hundred registrants a month, Contrast is the webinar tool shaped around that, with Pro at €79 a month billed yearly for 100 registrants a month (Contrast pricing, checked on 26 October 2026). The vendor pitches it as webinars "for modern software companies", with every data point synced to HubSpot and AI that turns sessions into content (homepage).

Before you switch:

1. Count unique registrants per month. Contrast charges on unique registrants, reset monthly, not on live viewers (pricing FAQ). For example, two webinars of 120 registrants each are at most 2 x 120 = 240 unique people, which fits the 250 tier at €179 a month billed yearly; overlap between the two lists lowers the count.
2. Map it to the HubSpot you have. Contrast writes its own contact properties, such as registrations, live views and replay views, and updates existing contacts without overwriting their name or latest conversion source (custom fields, contact management). Check those names against your lead scoring before the first session.
3. Pick the report you will read. Each webinar syncs to HubSpot as a Marketing Event with registrations, attendees and no-shows counted (Marketing Events), so the result sits next to your campaigns.

What Contrast does

It runs live, pre-recorded and recurring webinars from a browser studio, with branded registration pages, reminders, chat, polls, Q&A and calls to action. The replay appears on the same link as the registration page once the session ends, and registrants who missed it are told by the automatic emails (webinar recording).

The HubSpot side goes further than a contact sync: workflow triggers on attendance, polls and CTA clicks, one-click lists for no-shows or replay viewers, and an engagement card on the contact record (1-Click lists). After the session, Repurpose Ai drafts blog posts, summaries, newsletters and LinkedIn posts from the transcript, and Clip Ai cuts subtitled clips (repurpose your webinar). Contrast describes itself as a French company with data stored on local servers (help centre).

Who it suits, and who it does not

It suits a B2B software marketing team on HubSpot that runs a webinar or two a month. It suits less well a team on Salesforce alone, which is an add-on, or one that needs sessions longer than the 2 hours Pro allows.

What it costs

Pro in euros per month, checked on 26 October 2026 on the pricing page: €99 billed monthly or €79 billed yearly for 100 registrants, €229 or €179 for 250, €439 or €349 for 500. Pro includes Repurpose Ai 20 times and Clip Ai 10 times; Advanced, quoted, makes both unlimited. The free plan allows 30 registrants a month and 30-minute webinars, and deletes on-demand videos after 15 days.

Go over your registrant limit and Contrast keeps registration open, then moves you up a tier at the next billing cycle (pricing FAQ). Your webinar wins, and so does Contrast's invoice, by default; watch the monthly count in the week before renewal.

How it compares

Livestorm. Livestorm sells attendee credits instead, counted once per participant per session and used over 12 months, at €2.50 an attendee when you buy 400 on Pro; its native HubSpot and Salesforce integrations are marked Enterprise plan only (Livestorm pricing, same date). Choose it when attendance is patchy and you are not tied to HubSpot.

Zoom. Contrast's homepage pitches it as the switch from Zoom, whose webinar plans need a Zoom Workplace Pro licence (Zoom pricing). Stay with Zoom if one login for meetings and webinars matters more than the CRM sync.

Getting started

Run a test event first by duplicating one (test event guide). How to use Contrast turns one webinar into a month of follow-up content.
