The Essential Guide to Retention-as-a-Service (RaaS)
Explore retention as a service, the model that scales CS through human, digital, and agent-led programs.
What Retention as a Service actually is (and why it's not just a new name for CS)
Retention-as-a-Service (RaaS) is a category of B2B software and services in which AI agents and humans work together to deliver customer retention and growth as the contracted outcome, not just the workflow. Unlike traditional SaaS — where you buy a tool and your team does the work — RaaS makes the result itself the product.
Chapter 1
Why Retention-as-a-Service exists
Retention is now existential. Every customer matters, every dollar matters, and every revenue leader is being told to do more with less: hit your GRR number, be more efficient, scale impact without adding headcount.
For 15 years, the customer success model that Gainsight invented was human-centric by design. It worked for the accounts companies staffed against. But the long tail — the thousands, sometimes tens of thousands, of accounts that no human is managing — went largely unrealized. For most B2B software companies, that’s where the leak is.
AI changes that math. Gainsight introduced Retention-as-a-Service to combine human expertise with agentic scale — serving every customer segment, from strategic to long-tail, and improving both GRR and NRR through software and services.
“AI-Native Services” is an emerging market category describing companies delivering professional services outcomes primarily through AI, with humans in the loop. The customer buys a result and is indifferent to how it’s performed.
Chapter 2
How RaaS is different from just 'traditional SaaS'
When Gainsight invented customer success in 2009, software was the product and humans executed retention as a workflow. The tool tracked the work, organized the process, and enabled the team.
| Traditional SaaS | Retention-as-a-Service | |
|---|---|---|
| What you buy | A tool | An outcome |
| Who does the work | Your team | Agents + humans, together |
| Measured by | Feature usage, adoption | GRR, NRR, retention |
| Scales to long-tail | Only if you staff for it | By default |
That’s no longer enough. Technology is now expected to do the work and deliver results — not just enable the team that does. RaaS reflects that shift.
Chapter 3
Three ways to adopt Retention-as-a-Service
Through the use of AI, MCPs and CLIs, Gainsight has agentified its platform, giving customers the flexibility to build their own, buy proven agents, or hire Gainsight to run the work end-to-end.
Build
Build on the open platform. Use Gainsight’s MCP, CLI, and Cowork interfaces to build custom agents and AI workflows on our secure, enterprise-ready infrastructure. Gainsight solutions are now headless — your team can access every Gainsight product and all of your customer data from tools like Salesforce, Glean, or your favorite AI assistant.
Buy
Buy proven, pre-built agents. Where customization isn’t the priority, deploy agents trained on 15 years of Gainsight solution expertise — out of the box.
Hire
Hire Gainsight to deliver the outcome. Through Atlas, our AI-Native Services business, Gainsight deploys a pod of AI agents with humans in the loop to manage your long-tail renewals end-to-end. You don’t pay until you get the outcome. We are accountable for it.
Chapter 4
Why RaaS matters even when retention isn't your title
Some leaders read “Retention-as-a-Service” and assume it speaks to renewal managers and CS ops. It doesn’t. Education leaders, community managers, and product experience teams sit closer to retention than almost anyone — they just don’t always frame their work that way.
Education, community, and in-app engagement aren’t adjacent to retention. They’re the mechanisms of it. Customers who learn faster adopt deeper. Customers who belong to a peer community churn less. Customers guided in-product activate sooner. That’s why Gainsight’s five products sit inside one RaaS platform rather than five separate categories — because the outcome they all serve is the same.
- Gainsight CS: Customer Success. Detect risk early, diagnose the reason, activate the next best action, and learn from what worked — across the entire post-sale journey.
- Skilljar: Customer Education. Time-to-education is a retention metric. Customers who certify on your product onboard faster, expand sooner, and refer more — making education a direct contributor to GRR and NRR.
- Gainsight CC: Customer Communities. Peer-to-peer support deflects tickets, accelerates problem-solving, and creates the belonging that keeps customers from leaving. Community is the retention compounder.
- Gainsight PX: Product Experience. In-app guides, surveys, and engagement insights drive the adoption signals that predict — and prevent — churn. PX is where retention starts inside the product.
- Staircase AI: Engagement Intelligence. Real-time AI signals across every customer conversation — emails, calls, tickets — so the agents and humans working on retention see what’s happening before it’s too late.
- Atlas: AI-Native Services. For long-tail revenue you can’t staff against, Atlas deploys agents with humans in the loop to manage renewals end-to-end — outcome-priced, vendor-accountable.

Why Gainsight defines the category
Market. Gainsight invented the category, department, and titles of Customer Success. No one else can claim 15 years of playbooks, pattern recognition, and institutional knowledge across thousands of the world’s most complex CS organizations. The industry looks to Gainsight as the leading authority on customer success, retention, and growth.
Product. Gainsight is the only platform that covers the entire post-sale customer journey — and the only scaled company delivering retention as an AI-native service.
Community. Our customers belong to something: a community that moves the industry forward. “Come for the product, stay for the community” shows up again and again when customers describe why they chose and stay with Gainsight. That community gathers each year at Pulse, the world’s largest customer success conference.
Make retention the outcome you ship — not the workflow you manage

FAQs
Retention-as-a-Service (RaaS) is a category of B2B software and services in which AI agents and humans work together to deliver customer retention and growth as the outcome, not just the workflow. The vendor is accountable for the result, typically measured in Gross Revenue Retention (GRR) and Net Revenue Retention (NRR). Gainsight invented the category and is the leading RaaS provider.
Traditional SaaS sells you a tool and you do the work. RaaS delivers the outcome. In SaaS, software tracks the work, organizes the process, and enables humans to execute. In RaaS, agents and humans together do the work and deliver results. The customer buys retention, not features.
Retention is now existential for B2B software companies. Revenue leaders are told to hit GRR targets, be more efficient, and scale impact without adding headcount. The old labor-intensive model only served top-tier accounts, leaving the long tail — thousands of accounts no human manages — largely unrealized. RaaS combines human expertise with agentic scale to serve every customer segment.
RaaS is measured by the retention outcomes the customer cares about: Gross Revenue Retention (GRR), Net Revenue Retention (NRR), and customer growth. Under outcome-based pricing models, customers don’t pay until the result is delivered. The vendor is the single point of accountability.
Gainsight delivers RaaS through three modes: Build (use our open platform to build custom agents and AI workflows), Buy (deploy pre-built agents trained on 15 years of Gainsight expertise), and Hire (let Gainsight run your long-tail renewals end-to-end through Atlas, our AI-Native Services business, with outcome-based pricing).
AI-Native Services (AINS) is an emerging category, coined by Jake Saper at Emergence Capital, describing companies that deliver professional services outcomes primarily through AI with humans in the loop. The customer buys a result and is indifferent to how it’s performed. AINS is distinct from traditional software (you buy tools) and traditional services (you buy people). Gainsight enters this category with Atlas; retention is our committed outcome.
Education, community, and in-app engagement are not adjacent to retention — they are how retention happens at scale. Customers who learn faster adopt deeper. Customers who belong to a peer community churn less. Customers guided in-product activate sooner. Gainsight PX, Skilljar, and Customer Communities each contribute directly to GRR and NRR, which is why they sit inside one RaaS platform rather than separate categories.
