Sleak builds consistent, confident customer conversations across your whole service and success team, from renewal to escalation, before the call happens. Leaders define what the team must KNOW and DO, and the AI Coach develops each person through personalized dialogue and realistic voice simulations, scored against a Scorecard, with aggregate evidence tied to retention. Sleak is not a call-recording or call-analysis tool: it develops capability before the conversation, not analysis after it.
Revenue's second front
Acquisition gets the glory and the training budget. But the recurring revenue that actually sustains the business is defended somewhere else: in the renewal call where the customer mentions a cheaper competitor, the escalation where a furious stakeholder threatens to walk, the QBR that either opens expansion or becomes a status update. These conversations decide whether revenue stays, and they get a fraction of the preparation a first sales pitch does.
The second problem is consistency. Across a service team, the gap between your best handler of an angry customer and your average one is enormous. Customer number 400's experience depends entirely on who answers the phone. Today the only way most teams close that gap is to listen back to calls after the damage is done.
Sleak works the other way around. It develops capability before the conversation, not analysis after it. Sleak is not a call-recording or call-analysis tool. It does not monitor live calls. It builds the skill so the call goes well the first time.

Customer number 400's experience depends entirely on who answers the phone.
What your team must know and do
Every retention outcome breaks down into two things. What the team must KNOW: the new product changes, the updated pricing and policies, the escalation playbook, the renewal talk track. And what the team must DO: de-escalate a furious stakeholder, hold price in a renewal, surface an expansion opportunity in a QBR, say no without losing the relationship.
You define both. You set the outcome in Sleak, upload your materials — playbooks, policy docs, product notes, voice notes — and define the Standard of Excellence: the point at which a person has provably demonstrated they know and can do what the account needs.
How the Coach executes it
Coaching Mode (KNOW), shown in the app as the Knowledge Coach, develops understanding through personalized dialogue. When a product changes or an escalation policy updates, the Coach makes sure every agent has genuinely understood it, not clicked through it, so the answer a customer gets does not depend on who they reach.
Training Mode (DO), shown as AI-Roleplays, is where it becomes real. Your team practices the exact conversations that keep customers, out loud, against virtual counterparts that push back like real people: the churning customer with a competitor quote in hand, the escalation with a hard deadline, the renewal where procurement plays hardball. The upset customer has to feel real to be worth practicing against, which is why voice matters here more than anywhere. Sessions run in the browser and over the phone, and voice is the primary modality.
After each session, performance is scored against the Scorecard with specific evidence cited from the conversation, so feedback is concrete and the person always knows what to do next. The Coach is always available and endlessly patient. It belongs to the agent, not to their manager, so they can practice the hard conversations privately before they ever face a customer.
Service and success Initiatives
An Initiative is how a leader hands a retention goal to Sleak and gets proof it worked. Common service and success Initiatives:
- Renewal readiness. Every account manager can defend price, handle the competitor comparison, and steer a renewal to a confident close.
- Escalation standard. A consistent, calm, on-policy response to an angry or churning customer, so the outcome does not depend on who takes the call.
- Consistent service quality. Product changes, policy updates, and escalation playbooks understood and provably applied across the whole team, so the experience is even from your first customer to your four-hundredth.
- Upsell and cross-sell in CS. Turning the QBR and the check-in from a status meeting into a natural expansion conversation, without sounding like a sales pitch.
- Onboarding and ramp. Getting new service agents to standard faster, which matters most on high-turnover teams where a new hire is on the phone with a real customer within weeks.
From cost center to defended revenue
For the agent: a private place to rehearse the conversations they dread, until they walk into them ready.
For the leader: service moves from cost center to defended revenue. You get an Initiative tied to your retention goals, with aggregate evidence of who is ready and where the gaps are, instead of hoping training translated into behavior. The consistency gap closes because the whole team is held to the same Standard of Excellence, and new hires reach it faster.
