What changes from seed
At seed, you had nothing to point at except judgment. The announcement had to sell the founders and the insight, because those were the only assets in existence. That is a legitimate strategy and it works, see the seed announcement guide for how to run it.
By the Series A, that strategy has become a liability. You now have customers, usage, and numbers. Leading with the team slide when you have real traction signals that the traction is not worth mentioning.
The deeper shift is in who you are talking to. A seed announcement is read mostly by engineers you want to hire and investors you want to know. A Series A announcement is the first one your buyers will see, and buyers do not care who led the round.
Lead with the wedge
The most common Series A announcement structure, "We raised $X led by Y to build the future of Z", is three clauses of which only the third could possibly interest a buyer, and it is the vaguest.
Lead instead with the wedge: the specific, narrow thing you do better than anyone, evidenced by someone who pays you for it. The round becomes proof that the wedge is working rather than the headline itself.
A useful discipline: write the announcement with the dollar figure deleted. If the post still gives a reader a reason to care, you have something. If deleting the number empties the post, you are announcing a bank transaction and no amount of distribution will fix that.
Which numbers to disclose
Disclose something specific, even if it is not ARR. Every announcement claims strong growth, which means the claim carries no information and readers discount it automatically. A number they can hold is what makes a post travel.
| If you can share | Use this framing |
|---|---|
| ARR | The strongest option. A real figure with a time window beats any multiple. |
| Growth multiple only | Always attach the period. "4× in nine months" is credible; "4×" alone reads as spin. |
| Named customers | Two recognisable logos outperform a vague count. Get written permission first. |
| Usage volume | Works well for infrastructure and developer tools where revenue is early but usage is real. |
| Nothing at all | Then lead with the product itself and a demonstration. An announcement with no evidence needs to show something. |
Your audience is now buyers
Here is the structural problem. Your buyers are VPs of Engineering, Heads of AI, and operators at companies your size.
They pay for an ad-free feed specifically to avoid marketing. They do not read trade press with any regularity. The only route to them is the accounts they already chose to follow.
This is why a Series A announcement that reaches one million qualified views produces materially more inbound than one that reaches forty thousand, regardless of whether the round was $10M or $40M. Round size does not buy reach. Distribution buys reach.
The mechanism is engagement velocity: platforms decide how far to push a post based largely on how it performs in its first stretch of life. A company account posting cold is competing against its own cold start, and gets capped inside thirty minutes no matter how good the copy is.
The fix is an amplified first wave from accounts whose audiences overlap your buyer profile. That is the layer the full playbook covers in detail.
What one of these produced
The measurement above is worth running because the answer is rarely what the deck assumed. Here is an early-stage launch where the answer came back loud.
Codos, an a16z speedrun company, launched the first virtual Chief AI Officer from co-founder Dima Khanarin's account rather than a company one. The post passed a million views on its first day from about 1,800 followers and stands at 1.6M.
The inbound is the useful part. Two weeks later the founder's account of it was many VCs and many, many customers. We are overwhelmed.
That is the founder's report rather than a ranked attribution chart, which is why the question above is worth running on launch day. The full numbers are here.
A structure that works
- The wedge, in one line. What you do, for whom, better than what. No adjectives.
- The evidence. A number, a logo, or a demonstration. Specific enough to be checkable.
- The raise, in a clause. Amount and lead investor. One line.
- What the money changes. Concrete: what ships, what gets hired, what becomes possible.
- The ask. Hiring, design partners, or a link. Every announcement should have a next step.
Post it from the founder's personal account. Personal accounts consistently outperform brand accounts on both reach and trust, and the founder is the part of the story people actually engage with. Keep the account in-house, tone and legal exposure belong with you, and audiences detect a ghostwritten founder immediately.
Questions we get asked
How is this different from a seed announcement?
A seed announcement sells the founders and the insight, because that is all that exists. A Series A sells traction and the wedge. The audience changes too: seed is read by engineers and future investors, Series A is the first announcement your buyers see.
Should we disclose revenue?
Disclose something specific, even if it is not ARR. Growth multiples with a period attached, customer counts, usage volume, or a named logo all work. Vague growth claims are treated as noise because every announcement contains them.
How much pipeline should this generate?
It depends on distribution. Track qualified inbound attributed to the specific accounts that carried the post, and demo requests in the fourteen days after against the fourteen before.
