Evidence-to-revenue growth OS for X

Turn your expertise into
X posts that create leads.

Xfast writes original posts from your real knowledge, publishes them at the best time automatically, and shows you which ones create pipeline. No blank page, no calendar, no spam bots.

Connect your own X account. You approve every post before it goes live.

From expertise to published post in 3 steps

The whole loop is one safe workflow. You stay in control at every step.

1

Save your expertise

Drop raw notes into your Evidence Vault: real numbers, customer stories, hard-won lessons. No blank page, ever.

2

Generate & approve

An LLM writes founder-voice drafts strictly from your evidence. You approve with one click. Nothing is invented.

3

Publish at the best time

Approved posts go out automatically at high-engagement times, tuned by your own results. You never pick a date.

Built to grow a real audience, not vanity metrics

Evidence-first drafts

Every post is built from your real expertise, not recycled viral templates. Sources are shown on each draft.

Automatic best-time posting

Queue a post and forget it. Xfast picks the slot, keeps a healthy gap, and learns which times convert for you.

Originality guard

Drafts are checked against your past posts and common clichés, so you never sound like everyone else.

Revenue, not vanity

Track qualified conversations and leads per post, not just likes. See what actually creates pipeline.

Human approval built in

No auto-replies, no DM bots, no autopilot spam. A human approves everything before it goes public.

UTM links & attribution

Wrap your links, track the clicks, and log the conversions back to the exact post that drove them.

Evidence before generation.
Human approval before publishing.
Revenue before vanity metrics.

Most growth tools optimise for output. Xfast optimises for the two things that matter to a founder: sounding like yourself, and creating pipeline you can measure.

Questions

Does it post automatically?+

Yes. Once you approve a draft, Xfast schedules and publishes it to your connected X account at the best available time, without you touching a calendar. Publishing runs server-side, so nothing depends on you keeping a tab open.

Will it invent facts about me or my company?+

No. Drafts are written strictly from the evidence you save. If a claim is not in your evidence, it is flagged for review before you can approve the post.

Is this a bot that spams replies and DMs?+

No. Xfast only writes and schedules your own original posts. There are no auto-replies and no DM automation. A human approves everything public.

Do I need my own X developer app?+

Yes. You connect your own X account via official OAuth, so posts come from you and use your own API access. Setup takes a couple of minutes.

Stop staring at the blank compose box.

Save what you already know. Let Xfast turn it into posts that sound like you and bring in real conversations.
