What Quelta solves

Five marketplace tasks, one engine

  1. Cards without video

    Problem
    Most cards have photos only. Filming video for thousands of products is slow and expensive.
    Quelta
    Quelta makes a video for every card from its photos, by a scenario you set: hook, product shots, price, delivery and a call to action.
    Example
    A clothing category: 5,000 cards with photos → a 10-second video for each, with the price and delivery from the feed.

  2. One video, hundreds of products

    Problem
    A video that sells works for one product. Re-shooting it for every product isn’t realistic.
    Quelta
    Quelta keeps what makes the video sell (the hook, the pacing, the structure) and makes it again with every product in the category.
    Example
    One tested sneaker video → 300 versions, one for each model in the category.

  3. Quality at scale

    Problem
    Nobody can watch thousands of videos. A weak opening or an unreadable price slips through and costs sales.
    Quelta
    Every video passes the Quelta check before it goes live: 30+ metrics, platform rules and the practices of each market. Below your threshold, it goes back for a fix.
    Example
    The threshold is 70 out of 100: a video that opens with a 3-second logo is caught and fixed before it reaches a card.

  4. Videos for your sellers

    Problem
    Sellers want to promote their products on social media, but most can’t make a video ad.
    Quelta
    Give them Quelta in the seller account: ads for TikTok, Reels and Shorts made from their cards and leading back to your marketplace.
    Example
    A seller picks a card and gets 3 ads for TikTok and Reels with a link to it.

  5. The marketplace’s own campaigns

    Problem
    Sales, seasons, categories and new markets need dozens of fresh videos every week.
    Quelta
    Quelta makes videos for your own social media and performance campaigns, by category, by season and by sale.
    Example
    A seasonal sale: one scenario → videos for 20 categories in 5 languages.

Localization

Every country, language and generation of buyers

Localization is not translation. For each market Quelta changes the language and the captions, the presenter and the voice, the pace and what the offer leads with. And it makes separate versions for different generations of buyers.

  • Language, captions and voice of each market
  • What the offer leads with: price, installments, quality or delivery
  • Separate versions for Gen Z, Millennials, Gen X and Baby Boomers
  • US

    United States · English

    Leads with: the price

    $69, not $120+ for a logo

  • DE

    Germany · German

    Leads with: quality and free returns

    Kostenlose Rücksendung

  • BR

    Brazil · Portuguese

    Leads with: installments and a discount

    Em até 3x sem juros

  • JP

    Japan · Japanese

    Leads with: craft and detail

    職人の手仕事

And for every generation of buyers

  • Gen Z

    Fast cuts, a creator their age, humour and trends, the price up front.

  • Millennials

    Reviews and proof, value for money, a clear benefit in the first seconds.

  • Generation X

    Facts, quality and guarantees, a calmer pace and a confident voice.

  • Baby Boomers

    Large captions, clear speech, trust, service and an easy way to order.

Cases

How it looks in practice

One product for three markets, a catalog of pets from one photo each, and a check that catches mistakes before launch.

Case 2

Seller · 3 markets

One perfume → Mexico, Brazil and Saudi Arabia

A man makes perfume in his kitchen: cedar, cardamom and smoke. So far only his friends buy it.

Request
“Sell it in Mexico, Brazil and Saudi Arabia.” One phone video, in English.
Quelta
Three angles, not three translations: a compliment magnet in Mexico, lasts all day in the heat in Brazil, cardamom as the scent of hospitality in Saudi Arabia.
Result
Three local ads in Spanish, Portuguese and Arabic: native creators, voices, captions and calls to action.
  • Mexico
  • Brazil
  • Saudi Arabia
Case 1

Seller · USA

Embroidered pet tees → a gift ad for the US

A home embroidery shop puts customers’ pets on tees from one photo. Great product, no ads.

Request
A 10-second phone video: the tee, the shop with 6 pets and “Make me an ad for the US”.
Quelta
Found the angle on its own: a gift reaction, a genre that sells custom gifts in the US. Then the creator, voices, captions and edit for TikTok.
Result
A 15-second ad, “I put my mom’s dog on a shirt”, for US pet owners aged 25–45.

Case 3

Check · USA

A $900 ad, 3 orders → 28 mistakes found

A small skincare brand paid $900 for a beautiful horizontal ad. It brought 3 orders.

Request
A check for TikTok in the US, audience: Millennials. 18 out of 100, 28 mistakes, 4 of them critical.
Quelta
Pinned every mistake to a timecode, with a fix: a 3-second logo at the start, horizontal 16:9, only a tiny URL as a call to action.
Result
She fixed the worst ones: 69 out of 100 on the re-check. It didn’t go viral, but the orders came back.

Questions and answers

Do we need to film anything?

No. Quelta makes videos from the product photos and data you already have: the title, the price, the delivery terms. If a product has a video, Quelta can use it too.

How do you control the quality of thousands of videos?

Every video gets a Quelta score from 0 to 100 against 30+ metrics, platform rules and market practice. You set the threshold; videos below it go back for a fix and never reach a card.

Can our sellers use Quelta?

Yes. We connect Quelta to your seller account: sellers make ads for their own cards, for social media and for promotion on your marketplace.

Which countries and languages?

Any common language. For each market Quelta adapts the language, captions, voice, presenter and what the offer leads with, and it can make separate versions for different generations of buyers.

One-click fix and generationPrivate access

Run a pilot on one category

Generation and the one-click fix are in private access. Tell us about your catalog and markets, and we will set up a pilot.

We don’t copy other people’s videos. We keep the mechanics that sell (script, pacing, delivery) and make a new video about your product.
