Rec · About

PreFilm is the process I used at my last company.

I'm Henry Purchase. I turned YouTube into a six-figure revenue engine for my last company, then rebuilt the method so any business can use it.

YouTube Studio: Henry SaaS channel got 97,150 views in 28 days, more than ten times the 28 days before.

00:01The story

Why I built it.

The company was SEOSpace, a Squarespace SEO tool. I sold it in 2025.

Every video was chosen the way PreFilm chooses yours: the search demand and the format were there before I pressed record. The videos keep growing for years after they go up, because they answer what buyers already search for, not what was trending.

PreFilm is that method, done for you: it finds the videos your buyers already watch, shows you the evidence, and writes the script in your voice.

00:03What I won't do

Three things I won't compromise on.

  • Customers, not subscribers

    Every idea starts from what you sell, because views don't pay the bills.

  • Evidence, never a score

    If PreFilm can't show you why an idea works, it won't suggest it.

  • Your voice, not AI's

    Scripts are built from how you actually talk, and anything that sounds generated gets rewritten.

About PreFilm and Henry.

Who is Henry Purchase?

Henry Purchase is the founder of PreFilm. He turned YouTube into a six-figure revenue engine for his last company, SEOSpace, a Squarespace SEO tool, which he sold in 2025. Every video he made for it was chosen from search demand and proven formats before he pressed record, and PreFilm is that method built into a tool.

What is PreFilm?

PreFilm is a YouTube growth tool for business owners. It finds the videos your buyers already watch, compares each one to its own channel's normal, reads the comments and searches behind it, and turns them into ideas for what you sell, with the evidence attached and the script written in your own voice.

Who is PreFilm for?

Business owners who want customers from YouTube, not just views: consultants, agencies, coaches, service businesses and SaaS founders. If your videos need to bring in buyers, PreFilm starts from what you sell and the people you want to reach, rather than from what's trending or what gets the most views.

Is PreFilm a YouTube agency?

No. PreFilm is software you use yourself, in the app or inside Claude and ChatGPT. It does the research and writing an agency would, finding what to film and scripting it in your voice, and you film it. Henry once paid a YouTube agency about $5K a month for four videos.

How do I contact Henry?
