i'm david, korean founder building rinda.
exporters here make great products, then lose deals abroad to time zones, "dear sir/madam" emails and dead buyer lists.
rinda finds buyers who still buy and drafts in their language. a human hits send.
notes from the road here.

Exporters don’t need another lead list.
They need to know:
• who actually buys their product
• who is reachable
• what to say in the buyer’s language
• when to follow up
We built Rinda to turn global expansion into a repeatable sales workflow.

Our 1,000th signup didn’t feel like a vanity metric.
It felt like a reminder.
There are so many great products that never cross borders — not because the product isn’t good, but because global sales is still too hard to start.
Finding buyers.
Writing the first email.
Following up.
Building trust across languages.
After meeting founders across Korea, this problem feels more meaningful than ever.
Thank you to the 1,000 companies using RINDA.
We’ll keep building until great products no longer stop at the border.
Back to another late night.

日本のコスメは品質なら世界トップクラス。
でも海外で伸び悩む理由は「中身」じゃなく「届け方」なんですよね。
Kビューティーが世界に広がったのは
・トレンドの乗り方
・伝え方の設計
この"型"を、AIでJビューティーにも。

"'Your website looks sketchy.'
Five times this month. From serious prospects.
We have 300+ clients, 40% MoM growth, and a real product.
But our 2010-era landing page is killing deals before they start.
Today we're fixing this.
First impressions aren't vanity. They're velocity.

Most AI: "I looked once, here's my guess"
Mini-o3: "Let me check 30 different angles until I'm sure"
New research from ByteDance/HKU shows what happens when you train AI to be persistent instead of fast.
Visual search accuracy jumped 37% just by letting it think longer.

The gap between "AI lip-sync" and "AI actor" just closed.
🎭 Just dropped: AI that turns a single photo + audio into Hollywood-grade talking videos
Researchers from Kuaishou unveiled Kling-Avatar - it doesn't just sync lips, it understands intent
- Reads emotions from your voice
- Plans character movements like a film director
- Generates 1080p videos at 48fps
- Works on anime, cartoons, even cats playing guitar (yes, really)
The secret? They gave it an "MLLM Director" - basically an AI brain that creates a storyline before generating anything
Result: 60+ second videos where characters don't just mouth words, they perform - complete with gestures, expressions, and camera movements that match the mood
Wild part: It can generate hour-long videos in parallel, making each segment simultaneously. Digital humans for podcasts and education just became trivially easy.
See the demos → klingavatar.github.io
