Go live.
Sell out. Never oversell.

A live commerce platform for Korean influencers. One link lets viewers buy during an Instagram, TikTok or YouTube stream without leaving it, while stock locks in real time and KakaoTalk handles every order update.

The starting point

The challenge

01

Orders came in through comments

Sellers took orders from chat and DMs mid-stream, then spent hours afterwards matching names to payments.

02

Popular drops oversold in seconds

When a stream spiked, several buyers claimed the last unit. Refunds and angry messages followed every big sale.

03

Buyers had no idea what was happening

Without confirmations or shipping updates, sellers answered the same 'where is my order' question hundreds of times.

04

Platforms kept buyers inside their walls

Each social network had its own shop rules. Creators needed one checkout that worked wherever they went live.

What we built

A storefront that lives inside the stream

One link, every platform

A single share link works on Instagram, TikTok and YouTube. Buyers browse, add to cart and pay without leaving the live.

Real-time stock locking

Redis-backed reservations hold each unit for two hours, so traffic spikes never sell the same item twice.

Automated KakaoTalk alerts

Order confirmations, shipping updates and cart reminders sent straight to KakaoTalk, from as little as 12 KRW each.

Live analytics

Viewers, add-to-carts and conversions update while the stream is running, so sellers know what to push next.

How it works

Three steps to selling live

Built for creators, not developers.

  1. 01

    Connect and set up

    Link a Kakao account and add products in minutes, with no technical skills needed.

  2. 02

    Go live anywhere

    Share one MarketMate24 link on Instagram, TikTok or YouTube.

  3. 03

    Buyers check out

    Stock is reserved instantly and payment goes straight to the seller's gateway.

  4. 04

    Fulfil in bulk

    Shipping data exported as CSV and customers updated automatically on KakaoTalk.

Results & impact

What changed after launch

Before

Creators took orders from comments, oversold hot items and spent evenings reconciling payments and answering delivery questions.

After

Viewers buy mid-stream from one link, stock can never be double-sold, and KakaoTalk keeps every buyer informed automatically.
