Best Generative Video AI for startups

Last verified:

Crail tracks 6 Generative Video AI vendors that list startups as a fit. These are the 5 that rank highest once the list is weighted for startups, and each one is shown with what it costs to start and whether you can start today without a contract — the facts that decide the shortlist at this size, rather than the same summary on every page.

How this list is weighted for startups

  • 60% of the vendor's Crail agent-readiness score
  • 15 points for a published free tier
  • 15 points for being buyable self-serve, without a sales call
  • up to 10 points for a low entry price (free tier, then a cheapest paid tier under $30, then under $75)

Startups and small businesses share the price-and-self-serve weighting; midmarket and enterprise share the compliance weighting. The full rules are on the methodology page.

FAQ

How is this Generative Video AI ranking calculated for startups?

This is not the raw agent-readiness leaderboard. Crail scores the 6 Generative Video AI vendors it tracks that fit startups, using 60% of the vendor's Crail agent-readiness score; 15 points for a published free tier; 15 points for being buyable self-serve, without a sales call; up to 10 points for a low entry price (free tier, then a cheapest paid tier under $30, then under $75). Runway ranks first on both measures: it holds the highest raw agent-readiness score on this list (74/100) and the top score once the startups weighting is applied.

Which of these can a startup use without paying?

4 of the 5 publish a free tier: Runway, HeyGen, Pika and Synthesia. None of them are open source.

Do any of them require a sales call before you can buy?

No. All 5 can be bought self-serve, without talking to sales.
