Showcase

A selection of the videos
Sonder produces.

Every Sonder video is built on a script that's already been proven to work — then wrapped in imagery, animation, voiceover, and B-roll of your actual book.

The hook that hit 1.7M Relationship
The chapter that changed everything Memoir
Why this ending wrecks people Fiction
One silk thread holds Ron Wade’s entire war together Memoir
Power gone, towers down, phone useless Survival
Why nobody talks about this Self-improvement
Three rules every reader breaks Business
One paragraph. One million views. History
One nerve controls 80% of your panic?? Health
The fact nobody warned them about Psychology
What every parent has to hear Parenting

These are some of the videos that are generating millions of views.

Slideshows

What’s blowing up
on social media right now.

Four or five pictures your reader swipes through — with your book as the reveal at the end. It is the format winning attention on TikTok and Instagram right now — and it costs the same as a Quick Reaction Hook Video.

  1. 1 Slide 1 — If you keep sneaking looks at her belly and thinking I have no idea what I am doing, this is for you.
  2. 2 Slide 2 — Before the birth your testosterone actually drops. Your brain rewires so you snap awake at the baby cry.
  3. 3 Slide 3 — That fear of sleeping through everything and being useless? Biology already sorted it for you.
  4. 4 Slide 4 — There is one rule in there I broke on day one and instantly regretted. It is about food.
  5. 5 Slide 5 — The book itself: You Will Rock As a Dad The reveal

Amazon Ads

The ad your book page
deserves.

Social videos earn you the audience. This one closes the sale — 43 seconds, made for the page where readers actually buy, working for your book every single day.

One book. One ad. Included on paid plans.

How it works

Viral structure,
not luck.

We studied thousands of the videos that worked and reverse-engineered the pattern underneath — the hook, the tension, the reveal, the ending that earns the save. Sonder picks the proven script, then produces the imagery, animation, and voiceover around it — with B-roll of your actual book stitched through every cut.

A five-minute walk-through — from PDF in to video out.
  1. 01

    Upload your book.

    Drop in your manuscript and 30 seconds of B-roll of your book — the cover, a flick-through, a shot on your desk. PDF only. Sonder reads the whole thing, not a summary. No prompts. No briefs.

  2. 02

    Sonder finds a winning script.

    We've studied thousands of the videos that actually worked, and reverse-engineered the structure underneath. Sonder applies that proven viral pattern — hook, tension, reveal — to your arguments, your stories, your voice. Not a template. A script built to be watched to the end.

  3. 03

    Sonder produces the video.

    Voiceover, animation, motion graphics, captions — and your book woven through it. We stitch your B-roll into the cut so the thing readers are about to buy is on screen. A full production crew you don't have to hire, brief, or pay $2,500 a month for.

  4. 04

    Share, and go viral.

    Post to TikTok, Reels, and YouTube Shorts in one tap. The readers your book was written for — the ones still scrolling past, not knowing — finally find their way to you.

About Sonder

Built by two publishers
who help others get seen.

Sonder was built by two publishers who've spent their careers helping others get seen — on screen, online, and on the shelf. We know what it takes to cut through, because we've done it. Now we're putting that firepower into the hands of every creator, founder, and personal brand who's tired of shouting into the void.

Lexi Kaz, co-founder of Sonder

Lexi Kaz

Co-founder

Lexi is a seven-figure book publisher and the creative force behind the TikTok sensation "You Will Rock As a Dad" — a series that's amassed tens of millions of views and turned a children's book into a cultural moment. She started young. At five, she was flipping Lego figures on eBay. At fourteen, she was being recruited to play Division 1 soccer, and went on to play at the University of San Diego as the first in her family to compete at that level. When injuries and the pandemic forced a rethink, she bet on herself instead — dropping out at 19 to launch AK Infinite, a digital marketing agency that's worked with clients from Europe to Asia. Lexi has spent her career turning attention into outcomes.

"I built my whole career on figuring out what makes people click follow. Sonder gives that superpower to everyone."
Mike Langdon, co-founder of Sonder

Mike Langdon

Co-founder

Mike has been making video for over 20 years, and it shows. He's an award-winning video producer and the founder of one of Australia's biggest e-commerce video agencies, with a client roster that includes TikTok, Speedo, and Ring. When the BBC in the UK or the morning shows in Australia need someone to make sense of what's happening in media, they call Mike. He's also a seven-figure publisher with over 50 books to his name — but video is in his DNA. Sonder is what happens when two decades of "what actually works on camera" gets packaged into a tool anyone can use.

"I've spent 20 years being asked how to go viral. Sonder is a shortcut I wish I had on day one."
