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. You edit it and you decide. Before you publish, every post is reviewed on 7 criteria grouped in 4 families: hook, structure, call to action and voice, with what to fix for each one. 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. Plans start at 29 euros per month, with a 7-day trial.
