Video is no longer a nice to have in a marketing or sales motion, it is the format people expect, and increasingly, the format they convert on. But "video" covers a lot of ground, and two tools that often come up in the same conversation, HeyGen and BigMarker, actually solve very different parts of the problem. HeyGen creates AI generated avatar videos. BigMarker hosts and runs the webinars, product demos, and on demand experiences those videos often live inside. Understanding the difference matters before you pick either one.
Why this comparison matters right now
The numbers behind video as a format are not subtle. Video now represents over 82% of all internet traffic, and 94.6% of online adults watched online video in the past 30 days. On the conversion side, Wyzowl’s 2026 research found that 85% of people have been convinced to buy a product or service after watching a video, and 96% have watched an explainer video specifically to learn more about a product.
Landing page performance tells the same story. Adding video to a landing page can boost conversion rates by up to 86%, and sites that use video average a 4.8% conversion rate compared to 2.9% for those that do not, a 65% lift. For B2B SaaS specifically, explainer videos on landing pages have shown conversion lifts exceeding 100% in controlled testing. And 80% of people say they have downloaded or bought an app after watching a demo video, which is about as direct a line as you can draw from "watched a video" to "became a customer."
YouTube remains the center of gravity for all of this. Wyzowl ranks YouTube as both the most used platform among video marketers, at 82%, and the most effective overall. And the format is still accelerating: YouTube Shorts generated over 120 billion daily views in 2026, a 71% increase from the 70 billion reported in 2023, according to Google’s own Q1 2026 platform performance reporting.
So the question is not whether to invest in video. It is how to produce it efficiently, and how to deliver it in a way that captures leads and drives action. That is where HeyGen and BigMarker each play a role.
HeyGen: AI avatars that turn a script into a video
HeyGen is an AI video generation platform built around photorealistic AI avatars, voice cloning, and automated production. According to a 2026 pricing breakdown from Toolsurf, HeyGen now serves over 40,000 businesses worldwide, with avatars that can speak in dozens of languages, making it popular for product demo videos, training and onboarding content, personalized sales outreach, and localizing existing video into new markets.
On the product side, G2 scores HeyGen’s avatar quality at 9.2 out of 10, and reviewers consistently point to lip sync accuracy and multilingual translation as standout strengths. New in 2026, HeyGen added interactive AI avatars that can be embedded directly on websites for real time conversations, opening up use cases like AI powered virtual receptionists and interactive product demos that respond to visitors in real time.
Pricing is credit based, which is the detail most comparisons flag as worth understanding before you commit. HeyGen’s 2026 structure runs from a free tier through Creator at around $24 to $29 per month, Pro at $99, and Business at $149 plus per seat costs, with enterprise pricing available for larger programs. The catch, as Arcade’s pricing guide explains, is that premium Avatar IV videos consume credits quickly, so the headline price does not always reflect what a team will actually spend at scale.
In short: HeyGen is a content creation engine. It is the tool that turns a script into a polished, presenter led video without a camera, a studio, or an editor.
BigMarker: where the demo actually happens
BigMarker solves a different problem. It is a webinar and digital event platform built for marketers, combining live, automated, and simulive (pre recorded but presented as live) formats with registration pages, interactive engagement tools, and AI powered automation. As BigMarker describes its own platform, it offers "200+ features and industry leading customization and AI capabilities" and is built to "convert viewers into pipeline with always on experiences" using in player forms, offers, and polls that feed CRM data directly.
Reviewers on SalesHive describe BigMarker as a strong fit for small and midsize businesses that run frequent webinars or virtual events and want an all in one platform combining marketing, automation, and branding, commonly used for lead generation webinars and product demos, customer education and onboarding, virtual conferences, and thought leadership content series. On the AI side, BigMarker uses AI to generate insights, score attendees, enrich CRM data, and automate follow up messaging, turning what used to be a one off event into an ongoing source of sales signal.
Independent reviews on SoftwareAdvice frequently praise the platform’s reliability, polish, and SOC 2 Type II certification, while noting that the sheer depth of features can feel overwhelming to new users at first.

Where they actually fit together
The most useful way to think about HeyGen and BigMarker is not "versus" at all, it is "and." A common workflow looks like this: use HeyGen to produce a polished, multilingual product demo or explainer video without booking a film crew, then use BigMarker to host that video inside a simulive or on demand webinar experience, complete with registration pages, polls, CRM sync, and AI scored attendee data.
This pairing matters because of how conversion rates actually shift with video length and format. Demandsage’s 2026 data shows videos between 5 and 30 minutes converting at an average of 11%, and videos over 60 minutes converting at an average of 13%, both far above the 1% to 4% range for videos under three minutes. That favors longer, webinar style formats, exactly what BigMarker is built to deliver, while HeyGen can supply the polished presenter content that fills those longer formats without requiring a live presenter every single time.
It is also worth noting that companies using video in their marketing grow revenue 49% faster year over year, with 27% higher click through rates and 34% higher web conversions, according to the same research. That is the compounding case for investing in both the creation side and the delivery side of the video equation, not just one or the other.
The bottom line
If your bottleneck is producing video content, scripts sitting unused because no one has time to film, training material that needs to be localized into five languages, personalized outreach videos for a sales team, HeyGen addresses that directly, and its 2026 move into interactive, embeddable avatars suggests it is pushing further into live, on site engagement too.
If your bottleneck is what happens after the video exists, getting it in front of the right audience, capturing leads, and turning attention into pipeline, BigMarker is built specifically for that, with AI layered on top to make the follow up smarter.
Most growing marketing teams will eventually need both. The question is rarely HeyGen or BigMarker. It is whether your video strategy currently has a real answer for both halves of that equation, or just one.
