Growth and curation tools, with agents doing the work.

Both began as our own problem: things we saved with a goal in mind, piling up unread. Both are now tools where an agent reads what you saved, files it, and hands it back when it matters.

For X (Twitter)DiscoverCurateLive

Discover and curate X, with agents doing the reading.

TweetsMash is the curation tool for X. It syncs your bookmarks and lists, groups them by topic and author, surfaces what is worth your time, and mails you a digest when you actually read. Ask it anything you have saved and it answers with the source. Agents do the reading, sorting and recall; you keep the taste.

Discover, curate, create and grow on LinkedIn.

LinkedMash is the growth toolkit for LinkedIn. Import every post you saved, label it, search it in plain language, then turn the best ideas into your own posts with the Composer and schedule them at the right time. Agents handle the filing, recall and drafting; you publish.

Agentic travel booking.

Say it once — “book the usual to Chennai” — and an agent that already knows your travellers, your dates and your seats does the rest. Repeat trips first, then everything around them. Private beta in 2026.

About the founders

Two founders building for the agentic era.

ProductEngineeringDesignOperations

We hit the same wall everyone does: things we saved with a goal in mind, piling up in a void we never revisited. So we built TweetsMash for X, then brought the same idea to LinkedIn with LinkedMash. The next product takes it further — an agent that remembers so you don't have to — into travel. We are a two-person studio split between Tamil Nadu and Bavaria, which means someone is always awake.
