Your first 100 customers, from the agent you already build with.
First100 is a go-to-market toolkit that solo founders and indie hackers add to Claude Code, Codex, Cursor or ChatGPT over MCP. The agent that helped you ship writes the posts; First100 remembers the brand, schedules them on X, LinkedIn, Threads and Bluesky, finds conversations worth joining and tracks which posts bring signups.
What problem does it solve for a solo founder?
Distribution does not fit inside a coding session. It means four social dashboards, a posting habit, remembering what shipped last week, and no clear way to tell which post brought a signup.
With First100 connected, all of that becomes requests in the agent session you already have open: tell it what shipped, ask for a week of posts, ask what worked. There is no separate app to learn.
What does the first week look like?
Tell the agent about the product once. First100 stores the brand profile: audience, tone, content pillars, banned topics and posting hours. Then ask for a week of posts. The agent reads the brand context, picks times with suggest_slots, runs each draft through review_post and schedules them with save_drafts. Links become tracked links automatically.
Each morning the morning_brief prompt gives the numbers, the replies worth making and the next post. At the end of the week what_worked compares your own posts, so the next plan follows your results instead of generic advice. The full sequence is in the Your first week guide.
How does it help find the first customers?
reply_radar and find_conversations surface live threads on Hacker News and Bluesky where your audience is asking about the problem you solve. buyer_questions collects the questions buyers ask, which make good posts and pages.
For direct outreach, find_businesses searches local businesses through Google Places, and send_cold_emails sends from your own mailbox with a 1.5 second pause between messages and an opt-out line on each.
How much does it cost?
A week costs $5. Starter is $39/mo and Pro is $59/mo. Scheduled or published posts per month: 20 on the week trial, 300 on Starter and 600 on Pro. Your AI agent subscription is separate.
Does First100 reply, like, follow or send DMs for me?
No. Automated engagement is how accounts get restricted. First100 publishes the posts you approve and surfaces conversations worth joining with a drafted angle; you reply from your own account.
