Customer conversations for indie builders
Most founders treat marketing as content volume. What actually works is Diagnose first — paste real customer language, pick a campaign angle, join the threads where buyers already talk, ship Preview-ready copy, and close the GEO questions that do not name you. Growth OS remembers what worked so next week is sharper.
Free during beta — what we're testing & limitations
Beta program
Mark is free during public beta. Fair-use caps apply (lifetime content slots, AI usage meters, and a small lifetime AI budget per account — see Settings → Usage in-app). Paid Pro checkout only opens when we turn on paid live; we'll give notice before that happens.
Early access is limited while we stabilize the weekly loop. We may pause new signups or public access briefly between test rounds; check this page or /access-paused messaging if the app is temporarily closed.
The weekly loop
Home keeps you on pace — Diagnose, join a thread, ship Preview-ready copy, then close the GEO questions that do not name you.
Step 1
Diagnose first
After onboarding, Mark opens Diagnose. Paste CRM, tickets, surveys, or call notes. You get segments, pains, and up to five campaign angles in buyer language — then Growth OS keeps that memory.
Step 2
Join conversations
Inbox ranks Reddit, X, and Indie Hackers threads with reply drafts and freshness windows. Show up while the thread is still hot — help first, no link dumps.
Step 3
Ship from one campaign
Open a campaign to ship: strategy, content, calendar, and ship plan for that plan. Home triages all campaigns. Preview shows hook, body, and CTA as a founder would read them — JSON is only for edits.
Step 4
Measure the gap, then loop
Home counts posts due and failed posts from the full library. AI Visibility shows citation rank and lost questions. Ship the page for the worst gap, log outcomes, refresh Growth OS.
What's inside
Plan, Engage, Publish, Learn, and Tools — the same groups as inside the app. Workspace and campaign stay sticky; Growth OS compounds what you learn.
Plan
Customer language and a verified plan before you publish.
Diagnose
Paste CRM exports, support tickets, survey results, or call transcripts. Mark extracts segments, pains, objections, and up to five campaign angles — then sends first-run founders here before a blank campaign.
Campaigns
Focused acquisition plans with verification gates, 30/60/90 roadmaps, launch playbooks, and experiments. Filter Content and Calendar by campaign when you execute one plan.
Memory (Growth OS)
Marketing memory that compounds: customer truth, founder voice, winning hooks, market signals, agent job specs, outbound triggers, and transcript→assets.
Engage
Find buyers where they already describe the problem you solve.
Inbox
Reddit, X, and Indie Hackers threads ranked by relevance, with AI reply drafts in your voice and freshness windows so you show up while the thread is still hot.
Publish
Strategy-backed drafts, Preview, and campaign-scoped posting.
Content, Preview & Ship plan
Channel-ready drafts from strategy. Read Preview (not raw JSON), approve, and schedule. Auto-post where APIs are ready (e.g. Bluesky, SendGrid API); copy or finish drafts manually for LinkedIn and other social until connectors graduate from beta.
Calendar & build in public
Schedule across campaigns and ship weekly update templates that stay on-message without sounding like generic AI slop.
Learn
See what moves the needle and feed wins back into memory.
Home
This week, ranked tasks, visibility health, executive summary, and a Tracking card. Posts due today and failed posts count the full library — not a partial queue window.
AI visibility
Whether buyer questions name you — citation rank in the answer, lost questions, and a page to ship for the worst gap. Measure again after you publish.
Analytics & experiments
Outcomes, UTM link tracking, learning notes, and A/B angle tests that promote winning hooks into Growth OS for the next generation cycle.
Tools
Useful extras — not the weekly loop.
Landing Audit
Conversion and messaging score with prioritized fixes. Weak scores surface as a warning before you scale traffic.
Competitive
Competitor pricing, launches, and messaging change alerts so you are not surprised mid-sprint.
Directories
Startup directory listing checklist and submission tracking — one-time hygiene, not a fourth channel.

Why traction is hard
These aren't personal failures. They're structural. Almost every indie founder hits the same wall after shipping.
You post. Nothing happens.
You write the thread, schedule the LinkedIn post, drop a comment in a subreddit. You get a few likes. No signups. After enough of those, posting starts to feel pointless — so you either stop, or you post more frantically and get the same result.
You don't know which channel actually matters.
Should you be on LinkedIn or Twitter? Reddit or communities? SEO or email? Everyone has a different answer. Most of it is survivorship bias from someone whose audience, product, and timing were nothing like yours.
Your messaging is about your product, not your customer.
The landing page lists features. The posts explain what the tool does. But the people you're trying to reach are thinking about their problem, not your solution. Until your words sound like their internal monologue, they scroll past.
You're building an audience instead of finding buyers.
Follower counts and impressions feel like progress. They're not — not at this stage. The first customers almost never come from going viral. They come from direct conversations with people who already have the problem your product solves.
You iterate the product instead of the message.
When there are no signups, the instinct is to add a feature, lower the price, or redesign the landing page. But often the product is fine. The message is wrong. Until you've collected enough rejections to know what the real objection is, you're optimising in the dark.
Honest expectations
Mark surfaces customer conversations, drafts replies and Preview-ready channel content, compounds marketing memory in Growth OS, and tracks citation rank, lost questions, and outcomes so you learn faster each week. Auto-posting is limited to API-ready channels; social is mostly approve-then-you-post. It only works if you show up in threads, test messages, and log what happened.
There is no silver bullet.
Not AI. Not a viral post. Not a Product Hunt launch. Not a cold email sequence. Any tool — including Mark — is only useful if you already know who you're talking to and what problem you're solving for them. If that's not clear yet, the first job is to make it clear.
The first customers require founder effort.
Automation and AI can compress the work. They can't replace the conversations you need to have. The first 10 customers almost always come from direct outreach, personal trust, and showing up in the right places at the right time.
Fast iteration beats perfect strategy.
You will get the message wrong the first time. The channel mix wrong. The offer wrong. That's not a failure — it's the process. The founders who get traction are the ones who learn from each cycle faster than they lose momentum.
Most indie founders post content and hope for signups. What actually works is joining conversations where buyers already describe the problem you solve — grounded in real customer language, then shipping the right message and logging what worked. Mark runs that weekly loop from your product URL.
Indie hackers, solo founders, and small product teams who have something built but aren't getting traction. If you're unsure where to show up, what to say when you get there, or how to turn customer feedback into messaging, Mark is for you.
Paste your URL. Mark analyzes your landing page, asks a few focused follow-up questions, and saves workspace knowledge. After onboarding it opens Diagnose first — paste CRM exports, tickets, or call transcripts to extract segments, pains, and campaign angles in buyer language. Growth OS keeps that memory for the next cycle.
Growth OS is Mark's marketing memory layer. It stores customer truth, founder voice, winning hooks from experiments, weekly market signals, agent job specs, outbound triggers, and transcript→asset workflows — so every strategy and content generation cycle gets sharper instead of starting from scratch.
The workspace switcher scopes Home and your whole product. Open a campaign to execute; Publish routes Ship plan and calendar to your focused plan. Home triages all campaigns. Read drafts in Preview — JSON is only for editing.
It measures whether buyer questions name you in AI answers, at what citation rank, and which questions you lost. Ship a comparison or checklist page for the worst lost question, then measure again.
Inbox (/opportunities) is where Mark surfaces Reddit, X, and Indie Hackers threads where buyers already describe the problem you solve. You get relevance scores, a freshness window, and WARM reply drafts (why them, one question, a resource). Same page on web and iOS.
Landing Audit scores a URL and lists prioritized conversion and messaging fixes. A weak score can show up as a warning on your next campaign strategy so you fix the page before driving more traffic.
Yes during public beta — no card required. Fair-use caps keep the loop sustainable (content slots, AI meters, and a small lifetime AI budget per account). Pro checkout only appears when we enable paid live; we'll announce that on /beta first.
Not by default for browser-based social. Mark prepares Preview-ready copy; you post manually or use Copy for manual post where connectors are still beta. Bluesky and SendGrid (API key) can auto-post when you connect them. We don't run silent social autopilot.
Yes. Mark works in the browser and has an iOS app on TestFlight — the same live site. Cold start restores your session and last workspace, then opens Home. Campaign switcher and Preview work the same as on web.
