Done-for-you growth agents for a seed-stage startup are AI agents that someone else sets up and runs on your accounts to carry out a growth routine you have already planned: posting, replying in communities, outreach, launches and the weekly measurement, each on a schedule. Buy them when that routine is written down and keeps slipping for lack of hours, and buy from a provider that shows you every run, keeps a person on whatever goes out under your name where the platform requires it, and lets you stop after a short first round.
That is also what we sell, so read the rest with that in mind. Every number below comes from our own records: we have run these agents on our own accounts since June 2026, with every run on a public log.
Three things sold under one name
When we ran this question through GPT-6 Sol's search tool on October 27, its first results were agencies' own pages and lists of agencies: Demand Curve's home page, titled "The AI-Powered Growth Agency for Startups", Dooza's "AI Growth Agents for SEO, Ads, Website & Leads", Gallium's "The AI-Native Growth Agency", and several lists of the best growth agencies for startups in 2026. Claude's search tool returned 9 results, among them a Launchrock list of growth agencies, a product page calling itself an AI growth agent, a list of AI growth tools, and four untitled pages on two shared note servers. Neither search returned a page of ours.
So the phrase covers at least three different purchases, and the first job is to know which one is on the table.
| What is sold | Who decides what to say | Who presses publish | What to ask to see |
|---|---|---|---|
| An agency that uses AI inside its own process | The agency | The agency | The plan, and who on their side writes it |
| Agent software you operate | You | You, or the software once you switch it on | What the software does when a run fails |
| Agents someone runs for you on your accounts | You write the routine; the provider runs it | Per channel: the agent, or a person you name | Every run, on a log you can read without asking |
This post is about the third row. The first two are fine purchases; they answer different problems.
What a run-for-you setup does, from ours
Our agents run on our own company first, and each one's page lists what it does and what a person still does. Seven of them carry most of the weekly routine:
| Routine | Agent | Schedule | What a person still does |
|---|---|---|---|
| A post on X from a calendar of findings | X posting | Twice a day | Fills the calendar rows ahead of time |
| Replies under X posts people are reading now | X comment replies | Three runs a day | Presses Reply on each emailed link, or skips it |
| One Reddit comment | Reddit comment replies | Once a day | Pastes it in, or lets it lapse |
| A company page post on LinkedIn | LinkedIn posting | Daily, with a cap and set hours | Keeps the topic calendar filled |
| A blog post | Blog posting | Daily | Nothing per post; a person changed its topic rule in October |
| Cold email to founders | Cold email outreach | Each morning, five a day at most, since October 31 | Approves every answer to a founder's reply before it is sent |
| The week's counts | Weekly performance report | Tuesday and Friday | Reads it and changes the routine |
In the seven days to October 30 our agents put out 9 blog posts, 6 LinkedIn posts, 6 Reddit posts, 9 X posts and 3 Medium stories, and the X comment agent wrote 17 replies, of which a person posted 15; the other 2 were not posted. What came back was small: the nine X posts drew 78 impressions, and we have no paying customer.
Done-for-you growth agents for seed-stage startups: six questions before you buy
-
Can I see every run, including the failed ones? A log that only shows successes is a brochure. On October 19 our content review sent back that day's X thread because it gave one finding two sizes, 15 of 16 in one segment and 13 of 18 in the next; the record of that hold, left uncommitted, stopped the next three scheduled runs, and the next post went out on October 22. You can read that review on the content review log, and the gap is visible in the X posting log.
-
What goes out under my name with no person in between, channel by channel? Ask for the whole list. Ours: X posts, blog posts, LinkedIn company page posts, posts on our own subreddit, Medium copies of our Lab Notes, videos on YouTube and on our LinkedIn page, and cold emails (five a day at most) all go out with no person in between; the X posts, the blog posts and the video texts pass the content review first, the others pass only their own rules and caps. Three things wait for a person: X replies, Reddit comments, and every answer to a founder who wrote back.
-
Whose accounts are these, and what happens when the platform objects? They should be yours, logged in by you. Each platform draws its own line. X suspends accounts for browser automation, which is why our X replies are posted by a person. Reddit removes or bans a new account that comments carelessly, which is why our Reddit comments are too. LinkedIn's terms do not permit automation at all, and our LinkedIn agent posts to our own company page anyway, with a daily cap inside set hours: a risk we chose for our own page, and the reason that for anyone else's account it starts from drafts a person reviews. Ask a provider the same three things: the caps, the hours, and who solves a verification check when one appears.
-
Who writes the plan? If the provider also decides what to say and to whom, you are buying an agency with agents inside it, and you should judge their strategy. If you write it, they run it, and you should judge their execution. If a provider will not say which, ask who rewrites the plan when the numbers stay flat. Ours runs the plan it is given: since October 14 our X posting agent has taken the next pending row of a calendar we wrote, and it never picks a topic itself.
-
What happens when a site changes its page? Agents that drive a browser break when the page they drive changes. Since October 15 our Medium agent, and since October 24 our LinkedIn video agent, may repair their own script and commit the fix once a dry run, which stops short of the irreversible click, passes; a failure at the final Publish button itself still waits for a person. Ask for their version of that rule.
-
What will we count, and on what date do we decide? Pick three counts and a date before the first run. Ours, from the record of October 30: 78 X impressions from the week's 9 posts; 0 replies to the 32 LinkedIn messages we have sent founders since September 21; 0 paid customers. Write down which of yours would make you stop, before you see them.
What the agents will not do for a seed-stage company
They do not hold relationships. By October 11 our 32 cold LinkedIn messages had no replies (there were still none on October 30), while four founders we had met at events had written back; no schedule produced those four. They do not take a sales call, and our outreach list has produced 0 calls. And they do not notice on their own that the routine is wrong: in the week to October 23 our X comment agent put most of its 28 replies under SEO and AEO practitioners, peers who will not buy, until a person capped that lane at one reply a day on October 24 and turned it off on October 27. If those are the gaps at your company, the comparison in growth agents vs hiring a marketer matters more than this checklist.
Our own offer, and how to discount it
Every running agent's page, reachable from the agent list, has the setup to copy for free: the runtime, the browser profile, the accounts, the configuration and what to check on the first run. If you would rather not run it yourself, you can order the agent from its page, and we reply within one working day with how we would run it and what it costs; we price per agent and print no number yet. Discount our version of the six answers above for one reason: every figure in this post is from our own records, none older than June 2026, and no client has run the routine yet.
How we checked
The search results are our probe of October 27: this question searched once on GPT-6 Sol's search tool (through the Codex CLI) and once on Claude's, with the result lists kept. The week's counts are from our weekly performance record of October 30 (October 24 to 30); the outreach totals (32 messages, 0 replies, 0 calls) are from the same record, counted on October 30, and the four founders met at events are from our outreach report for October 5 to 11; the X reply lanes are from that agent's configuration notes; the review hold and the self-repair rule are from our content review ledger and our engineering notes. Nothing here comes from a vendor's sales call.
Disclosure
ClawWorld runs AI growth agents for early-stage startups and small businesses: they carry out the growth routine a team already planned on a schedule, with every run on a public log, and AEO (answer engine optimization) is one of the services. It competes with the agencies and products named above. None of them was contacted about this post or paid to appear in it.
