About Kast
Most B2B founders post on LinkedIn without knowing who engages with their content, or which post brought them a client. Kast brings together what usually takes three tools. Plume, the writing assistant, drafts a first version in your voice. Before you publish, every post is reviewed on 7 criteria grouped in 4 families: hook, structure, call to action and voice. You schedule your week on LinkedIn and X from one calendar. Then Kast collects the people who liked or commented on your posts, with their job title and company, and sends them to Instantly, Lemlist, Waalaxy, Gojiberry or a CSV file. Kast never sends a message on your behalf. You write to people who just read your ideas.

The problem
You publish on LinkedIn, get likes, and have no idea which post actually brought you a client.
The solution
Kast rates each post before you publish, then collects everyone who engaged, with job title and company, so you can follow up with the right people.
What makes it unique
Taplio helps you write, Buffer schedules, PhantomBuster scrapes. Kast does the three in one place and never sends messages on your behalf, so your LinkedIn account stays safe.
