Join SaaS founders growing on X.
Your daily workspace. AI runs, you steer.
The problem
SaaS founders lose on X because they can't keep up.
No time to post, reply, or monitor daily
Inconsistent presence kills audience growth
Miss 80% of relevant conversations and leads
Existing tools only solve one piece of the puzzle
DMs from interested leads sit unread for days
Can't tell what's actually working without spreadsheets
You don't need another scheduler or dashboard. You need someone to actually run it.
The backbone
Not "AI content." A strategy engine that thinks like a marketing expert.
01
Positioning
Who you are, who you serve, what makes you different. The AI uses this to filter every action.
02
Voice & Brand
Tone preset, banned phrases, do-and-don't rules. Keeps every output sounding like you.
03
Content Pillars
Topics weighted by what your audience actually cares about. No random posting, ever.
04
Campaign Cadence
When to post, when to engage, when to stay quiet. Strategic timing, not bot-like spam.
How the loop runs
Strategy drives every action.
Strategy → Plan → Action → Review. The AI never operates "off-strategy." When something underperforms, the strategy gets refined, not the other way around.
Strategy
Plan
Action
Review
Review feeds back into Strategy
Features
Five features. One AI operator running them all.
Replies
Tone-matched replies, drafted while you sleep.
Postvoy watches the comments on your published posts, reads the context, and drafts a reply in your voice. Send it yourself or queue it for one-tap approval — you control every word that goes out.
- Voice-matched to your tone preset
- Relevance scored before drafting
- Approve, regenerate, or skip

· 4mView on X ↗Just shipped a new analytics feature. Would love thoughts from anyone in dev tools.
Love that you're shipping fast. Are you tracking time-to-first-insight? That's where most analytics tools quietly lose people.
Why: on-topic, adds a concrete metric, matches your founder-casual voice.
Opportunities
Spot the conversations that matter.
Postvoy monitors your tracked accounts and topics around the clock. Every match comes scored by confidence with a ready-to-send draft, so you engage where it counts instead of triaging noise.
- Account + keyword matching
- Confidence-scored, no random pings
- One-tap reply or DM follow-up

View on X ↗What's everyone using to schedule and automate X posts without losing the human voice?
The trick is keeping it on rails: voice presets + your own examples, not raw GPT. Then you review before anything goes out.
Why: directly answers the question and earns a soft product mention.

Anyone built an AI that actually understands brand voice? Most just sound like ChatGPT.
AI Context Builder
A profile the AI actually understands.
Onboarding turns your product, audience, voice, and rules into a structured profile. Every post, reply, and DM runs through it — so the AI sounds like you, never like generic ChatGPT output.
- Brand voice + banned phrases
- Tracked accounts + keywords
- Safety rules, always enforced

The unsexy truth: most "AI marketing" tools just paste GPT output. The real wins come from the system around the model — voice, guardrails, context.
✦ Why: high-signal take for your audience, balanced against your Tools pillar.
Shipped a new opportunity-matching prompt today. Recall up 18%, false positives down 31%.
