A vertical video agency creates videos in 9:16, the format of a phone held upright, for TikTok, Instagram Reels and YouTube Shorts. Esekai, a Paris-based video agency, writes, shoots and edits these short-form videos for brands: organic content, creative ads, UGC videos and AI-generated videos.

What is vertical video, and why does it dominate?

A vertical video is watched full screen, phone in hand, in the middle of a scrolling feed. It lasts from a few seconds to a few minutes, is often watched with the sound off and is won or lost in its first few seconds: if it doesn't stop the thumb, it doesn't exist.

It dominates because that's where attention is. In France, mobile accounts for 80% of time spent online according to Médiamétrie. TikTok has 27.8 million monthly users there, Reels accounted for half of the time spent on Instagram in April 2024 according to Meta, and YouTube counts more than 200 billion Shorts views a day. For a brand, a cropped horizontal video is no longer enough: a vertical video is written for the format.

Short-form video agency, short video agency, 9:16 video agency: the same job

Vertical video agency, short-form video agency, short video agency, 9:16 video agency or vertical video production: these names all describe the same work, creating videos in the phone's format for the TikTok, Instagram and YouTube feeds, both organic and paid. In English, the terms used are vertical video agency or short-form video agency.

What Esekai does as a vertical video production agency

Four families of videos, made by the same in-house team and often shot on the same day:

• Organic TikTok, Reels and Shorts content: series of videos that keep your accounts alive week after week, with a version for each platform. It's the core of our short-form video agency;
• Creative ads: vertical ads for TikTok Ads and Meta Ads, delivered with two distinct hooks, testable as two separate ads. See our creative ads;
• UGC videos: creators who present your product the way your customers would talk about it, chosen with you. See our UGC agency;
• AI-generated videos: short-form videos, AI UGC with avatars and ads rolled out in many variants, scripted and checked by the team. See our AI video agency.

Our vertical video production method

1. The 30-minute call: your goals, your accounts, your platforms and what you already publish.
2. Strategy and scripts: a Creative Strategist analyses your brand, your audiences and your competitors, then proposes concepts and scripts with several hooks to test.
3. Casting and shoot: profiles are approved with you from a pool of more than 300, then the team shoots in the studio in Paris or at your premises, on iPhone or 4K camera depending on the look you want.
4. Editing and variations: pacing, subtitles and sound, a version for each platform, several lengths depending on the goal.
5. Tracking: the views, completion and engagement of every video, to improve the next ones.

Allow 15 to 20 working days on average between signing and the first videos. Each video includes two rounds of revisions, and a single project manager looks after you from brief to delivery.

Who is it for? Vertical videos for every type of business

For any business whose customers spend time on their phones: e-commerce, beauty, fashion, luxury, automotive, education, apps, software, B2B services, restaurants and institutions. Formats change from sector to sector, but the logic stays the same: grab attention fast, hold it to the end, give people a reason to act.

For Marionnaud, we built the brand's TikTok account from A to Z, taking it from zero to 10,000 followers. For BYD, our creative ads cut the cost per click by 2.6x on TikTok Ads and Meta Ads. For PST&B, six creative ads brought in more than 2,000 new sign-ups. For Royal Kingdom, Dream Games' mobile game, we shot ten UGC concepts in Paris, rolled out into a hundred files.

How do you choose a vertical video agency?

Six criteria to check before signing, whatever the agency:

1. Volume: an account or a campaign thrives on consistency. Ask how many videos come out each month and how they are produced, in batches or one at a time.
2. Testing: in advertising, a single video is not enough. Ask how many concepts and hooks are tested, and how the results shape the next videos.
3. Hooks: the first few seconds decide everything. A good agency writes several openings per video and can explain why each one might work.
4. Rights: who can use the videos, for how long, on which channels, and whether paid advertising is included. For creators and voices, everything must be in writing before the shoot.
5. Turnaround: how many days between signing and the first videos, how many rounds of revisions, and who your day-to-day contact is.
6. Proof: case studies with measured figures, such as cost per click, cost per lead or followers gained, not just views.

At Esekai: series shot on the same day, two distinct hooks per creative ad, rights set out in the quote, 15 to 20 working days before the first videos, two rounds of revisions per video, a single project manager and case studies made public.

How much does a vertical video agency cost?

At Esekai, prices start at €5,000 excl. VAT for 10 videos, i.e. €500 excl. VAT per video (prices as of November 2026).

The budget depends on the number of videos per month, hook variants, creators, usage rights, the share of filming versus AI, and languages. A series shot on the same day costs far less per video than a one-off video. We draw up a quote after a 30-minute call. For market ranges, see how much a short-form, UGC or creative ads video costs.
