The unglamorous truth

You shipped. Now no one knows.

You used the AI tools. You shipped. Maybe it works really well. Now you're back on social asking "how did you get your first users?"

Part of the honest answer is this: somewhere right now, someone is publicly describing the exact problem your product solves, and they don't know you exist. Show up and answer their question well — you don't have to "do marketing," you just have to be there.

ZeroCold helps you be there.

How it works

Three steps. Then you mostly forget about it.

01

Discover.

Connect the social platforms where your users hang out. Tell ZeroCold what your product is and which keywords matter. A classifier you tune filters every match before you see it.

02

Draft.

When someone posts something your product genuinely helps with, ZeroCold writes a reply in your voice — citing your knowledge base, not making things up.

03

Approve.

You see the post and the draft side-by-side. Approve in inbox or Slack. You post from your own account. No approval, no post. Ever.

The funnel

Your name is the CTA.

Inline links get treated as spam. Your name doesn't.

01

No links in the reply.

Drop a URL in a comment and the algorithm flags it. The community mutes you. Drop a thoughtful reply and the reader does the next step themselves.

02

They click your name.

A good reply earns curiosity. Curiosity earns a profile-click. That click is where you actually get found.

03

Your bio is the landing page.

What you build, who it's for, the link. ZeroCold helps you get the bio right on each platform.

Your reply is the introduction. Your bio is the landing page. That's the whole funnel — and it works because it stays inside what the community considers legitimate behaviour.

A simple bet

One good reply earns more than a hundred drive-bys.

Communities can smell inauthentic replies in two seconds. Anything that looks like marketing gets treated like marketing — muted, blocked, banned.

So ZeroCold makes some choices most outreach tools wouldn't:

  • You post from your own account. No rotating personas, no brand handle pretending to be a person.
  • The reply leaves the product link off. Your bio handles that. People who like your comment click your name to find you.
  • Drafts sound like someone in the conversation. Not someone selling. Because the alternative is what gets accounts muted.

If that matches what you're trying to build, ZeroCold's for you.

Built for

People who actually built the thing they're talking about.

ZeroCold works best when you can answer questions about your product because you're the one who made the decisions in it.

this is exactly the problem keepmysubs solves — connect your gmail and bank, it pulls every recurring charge into one view and flags the duplicates and the ones you haven't opened recently. free tier covers most people's setup.

Why ZeroCold is different

Not a growth-hack tool. Not a scheduler. Something else.

FAQ

The questions everyone asks first.

Is this spam?
No. Spam is sending the same untargeted message to a list. ZeroCold only surfaces posts where someone is asking for help with a problem your product solves, drafts a reply that addresses *their* situation, and never sends without a human approving it. If you wouldn’t reply to that post yourself, you shouldn’t approve it.
Will I get my account banned?
You shouldn’t — because you’re the one approving every reply, ZeroCold won’t let you carpet-bomb a community, and replies never carry inline product links (the single biggest signal moderation tooling reacts to). If a platform isn’t safe to automate at all, we don’t support it.
Does it post automatically?
Never. Every draft requires you to approve it — in the web inbox or in Slack. You post from your own account.
Which platforms work today?
Bluesky, Mastodon, GitHub Discussions, and Discourse are live. YouTube comments is the next adapter coming.
Can I see a sample reply before I sign up?
Yes — scroll up to "What ZeroCold actually puts in front of you." That’s a real Bluesky post and the reply ZeroCold drafted against a sample knowledge base.
What about X / Reddit / LinkedIn?
X and Reddit are intentionally off — both networks are aggressive about bot detection and the only safe answer is "don’t automate." LinkedIn isn’t on the roadmap; if we add it later it would be research-only (surface relevant posts, you reply by hand).
How much will it cost?
Pricing is still TBD. The beta is free for everyone we invite; we’ll figure out paid plans once we’ve seen what real usage looks like.
Can I bring my own Slack?
Yes. Each workspace can either use the built-in Slack app or paste a token, signing secret, channel ID, and App ID from your own Slack app. Setup guide is in the dashboard once you sign in.
Beta program

We're using it ourselves first.

Beta access opens once we're confident the drafts produce replies you'd post under your own name. Drop your email to be among the first invited.
