GongHow Posto9 Works
Measure value. Read interactions. Build strategy. Give the steps.
Four moves, one continuous loop. Each customer makes the system more accurate for that customer. No templates. No setup forms. We do the inferring.
Measure value
Against each customer's own success criteria, in their own business terms. Not logins. Not feature clicks. Not a generic health score. We infer what they pay you to deliver, then track it.
Read interactions
What customers say, what they don't, what they do. Across email, Slack, Teams, WhatsApp, calls, support tickets, NPS. Continuously processed.
Build strategy
Per customer. Generated from live signals. Goal, ordered steps, expected outcomes, confidence, timeline. Reasoned from their own conversations, not configured from a library.
Give the steps
Drafts emails. Posts updates to Slack. Creates tasks. Drafts ROI reports. Tracks meetings. Two-way Salesforce and HubSpot integration. Human approval is the default at every step.

The moat
Reasoning compounds. Templates plateau.
Posto9 doesn't ship vertical templates. Each customer's success picture deepens with every conversation signal. Year one we know what success looks like for them. Year two we know it sharper than they describe it themselves. Year three, a competitor still reaching for templates per vertical starts from zero against three years of compounding reasoning.
Today's tools measure usage. Posto9 measures value.
Templates plateau. Reasoning compounds.
Dashboards report what happened. Posto9 runs what happens next.

Posto9 helps me focus on being strategic with my customers. No more time wasted with tactical work.
Dan L., CS Lead, active design partner
Our Team
Built by people who've lived the post-sale.
Post-sales leaders and engineers who've run the work themselves and built systems at scale.
Experience from
10+ years in post-sales leadership
Deep experience running post-sales at fast-growing B2B SaaS companies. We have hired, fired, and rebuilt CS teams.
20+ years in engineering
Built systems at scale for some of the world's largest tech companies. Reasoning-capable LLMs are the unlock.
Lived the problem
We have lost customers we could have saved. That's why we're building Posto9.
"We didn't build Posto9 because we thought AI was cool. We built it because we have spent decades running post-sales by hand, and reasoning-capable AI finally makes a different operating system possible."
