A directory of AI customer success tools, by stage
The SuccessByCS Vendor Directory is a free directory of AI post-sales tools for B2B SaaS customer success teams. It sorts customer success software by the stage of the customer journey it supports: the sales-to-CS handoff, customer onboarding, activation, adoption, support, expansion, renewal and advocacy. Heads of Customer Success and SaaS founders use it to see which AI tools exist for a stage, such as customer health scoring or churn prediction, before booking demos.

Questions about AI customer success tools
What is the SuccessByCS Vendor Directory?
The SuccessByCS Vendor Directory (vendors.successbycs.com) is a free directory of AI post-sales tools for B2B SaaS customer success teams. It groups customer success software into eight stages of the customer journey, from the sales handoff to customer advocacy. It's kept by Chris Sparshott, a customer success, support and renewals leader at SuccessByCS.
What are AI post-sales tools?
AI post-sales tools are software products that use AI to help a company keep and grow customers after the deal is signed. Examples include AI notetakers for the sales-to-CS handoff, onboarding automation, in-app guidance, customer health scoring, AI support agents, expansion signals, churn prediction and voice of customer (VoC) analysis.
Which customer success stages does the directory cover?
Eight stages: Sign-up (the sales-to-CS handoff), Onboard, Activate, Adopt, Support, Expand, Renew and Advocate. Each vendor is listed under the stages its own website says it serves.
How are vendors chosen for the directory?
We search for AI tools built for each customer success stage and keep software vendors. Agencies, consultancies, publishers and review sites are left out. No vendor is listed for any reason other than what it does.
Where does the vendor information come from?
From each vendor's own public website: product, pricing, integration and security pages, and customer stories. G2 ratings come from G2's public pages. Details the vendor's site doesn't give, such as founding year, can come from another public source. An AI web search finds those, and we keep the source and its exact words. Most profiles list the pages they came from. We're rebuilding every profile under stricter rules: robots.txt checked before every page, a slow pace, every fact linked to its page, and a person's review before it's published. We don't add claims we can't source.
How do I choose the right AI customer success tool?
Start with the stage where your customers stall, not with the tool. If onboarding drags, look at onboarding and activation tools; if renewals surprise you, look at health scoring and churn prediction. If you're not sure where the problem is, the Post-Sales Reset at postsales.successbycs.com finds where customers get stuck between the signed deal and renewal, and what to fix first.
Is the SuccessByCS Vendor Directory free?
Yes. It's free to use and there's no sign-up.
How can a vendor correct or remove its profile?
Email directory@successbycs.com with the page to change. We correct or remove the profile.
