Visibility in this ranking can be paid for. Payment gives a vendor more visibility, higher up on the review pages; it never adds a vendor, and it never changes a word of the review. The largest vendors in customer success software
cannot hold places 1 to 3. Places 1 to 3 go to challengers, vendors outside the best-known brands in a category,
wherever the category has them; the established names follow from place 4 in their ranked order. How it works: placement disclosure ·

The 12 tools, reviewed
#1 Custify
Customer success platform for small SaaS teams · Romania · custify.com
Data stored in Germany No setup fees ISO 27001 and SOC 2
Custify ranks first because the company states plainly where the data sits and what it will not charge for. Its site says data is held in secure data centers in Germany, that it is GDPR compliant, ISO 27001 and SOC 2 certified, and that there are no setup fees, which removes a common surprise line item.
- Pricing: Quote only. Flexible pricing with no setup fees; the pricing page we fetched showed no tier prices, so figures come from a sales conversation. Free plan: none.
- Best for: SaaS teams of 2 to 15 CSMs
- Strengths: Customer health scoring; Customer 360 view; Automated playbooks.
Where it falls short
Public information is thin: the pricing page we fetched exposed no tiers or figures, and no trial is described. Its reach among large enterprise accounts, and the depth of services automation or portals compared with Planhat, is limited.
Wrong for
A large company with hundreds of CSMs, complex role hierarchies and a services arm.

#2 ClientSuccess
Customer success platform with SuccessScore health tracking · United States · clientsuccess.com
Package tiers by customers No setup fees Implementation 4-6 weeks
ClientSuccess lands second because it is unusually open about how its packages are drawn. The pricing page names three: Startup up to 500 customers and 10 licenses, Growth up to 5,000 customers and 50 licenses, and Enterprise with no stated limit, with no implementation fees and annual contracts discounted against month-to-month. It states implementation takes 4 to 6 weeks.
- Pricing: Quote only. Startup package up to 500 customers and 10 licenses, Growth up to 5,000 customers and 50 licenses, Enterprise unlimited. Free plan: none.
- Best for: Small and mid-sized B2B teams
- Strengths: SuccessScore health tracking; Pulse reporting; Journey management.
Where it falls short
There is no self-serve trial: the vendor says it offers demos and proof-of-concept work instead. Prices are not shown, and its claim of being 30 to 50 percent cheaper than Gainsight is its own marketing.
Wrong for
Anyone who wants to test with their own data before talking to sales, or who needs stated EU hosting.

#3 Velaris
AI-native customer success for B2B SaaS · United Kingdom · velaris.io
5-user base license Unlimited viewers UK data storage
Velaris ranks third because it is the youngest product here, with a pricing structure that is still unusually legible. The pricing page describes a base license of 5 users with unlimited viewers, with the Customer Portal and Support products sold as add-ons, organized around View, Analyze, Orchestrate and Execute.
- Pricing: Quote only. Base license of 5 users with unlimited viewers; Customer Portal and Support are separate add-ons; custom estimate on request. Free plan: none.
- Best for: Mid-market and enterprise SaaS in the UK and EU
- Strengths: View, Analyze, Orchestrate, Execute modules; AI agents; Health scoring and churn prediction.
Where it falls short
Its legal entity is MANANTIAL LTD, company number 13088838, registered in England and Wales, and neither its pricing nor terms pages gave a street address.
Wrong for
A small team that needs a published entry price, or a company that requires an established vendor with years of references.

#4 Planhat
Agentic customer platform for B2B teams · Sweden · planhat.com
Quote-based EU or US hosting CS, CRM and PSA
Planhat earns its place because it is the one product here built by a European company that also lets you choose where the data lives: its GDPR commitment says hosting is offered in the EU and the US, with production, backups and recovery in the chosen region.
- Pricing: Quote only. Quote-based with add-ons such as an upgraded AI platform, advanced service, email marketing and advanced portals; no prices published. Free plan: none.
- Best for: Mid-market SaaS with EU data needs
- Strengths: Customer success platform; CRM configuration; Professional services automation.
Where it falls short
Pricing is by quote with several paid add-ons, so the first number you hear is rarely the final one.
Wrong for
A three-person team that needs a simple health dashboard and a fixed price this week.
Visit Planhat →
#5 Vitally
AI-assisted workspace for customer success teams · United States · vitally.io
Three touch-model plans Unlimited automations Unlimited observers
Vitally earns fifth place on how clearly it is packaged. All three plans carry the same core features, unlimited automations, unlimited observer seats and single sign-on, and what changes is the motion you run: one-to-many, hybrid or one-to-one. That removes the usual game of finding which feature sits behind which tier.
- Pricing: Quote only. Three plans (Tech-Touch, Hybrid-Touch, High-Touch) with identical core features; no prices published, pricing on request. Free plan: free trial.
- Best for: Mid-market teams wanting fast adoption
- Strengths: Health scores; Playbooks; Hubs.
Where it falls short
No prices are published, so you cannot compare it with a competitor before a sales call.
Wrong for
A European company that needs a stated data region in its contract, or an enterprise with a large services team.

#6 Gainsight
Enterprise customer success platform and product family · United States · gainsight.com
Quote only Tiered by users and accounts Product family
Gainsight sits at sixth because the largest vendor in the category cannot take the top three, and it is the benchmark every other product here is measured against. Its pricing page shows how it sizes a deal: Essentials with 10 full users and 100 customers per user, Enterprise with 20 full users and 200 customers per user, both with unlimited viewer licenses.
- Pricing: Quote only. Customer Success Essentials includes 10 full users at 100 customers per user, Enterprise 20 full users at 200 customers per user. Free plan: none.
- Best for: Larger CS orgs with dedicated admins
- Strengths: Customer success platform; Skilljar academies; Product Experience analytics.
Where it falls short
It asks you to request pricing for most products, and the page we fetched described no hosting regions.
Wrong for
A team of fewer than five CSMs without a dedicated admin.

#7 ChurnZero
Churn-focused platform with in-app messaging · United States · churnzero.com
Quote only In-app communications Renewal forecasting
ChurnZero fills seventh place as the closest rival to Gainsight on features that is not part of a wider product family. Its homepage lists health scoring, journeys, plays, in-app communications, renewal forecasting and NPS, CSAT and CES surveys in one platform, with more than 50 integrations including Salesforce, HubSpot, Slack, Microsoft Teams and Zendesk.
- Pricing: Quote only. No prices published on the pages we could load; the pricing URL returned an error, so cost comes from a quote. Free plan: none.
- Best for: B2B SaaS with mid-sized CS teams
- Strengths: Health scoring; Journey management; Plays and automation.
Where it falls short
The homepage gives no pricing, trial or legal entity name beyond a copyright line, and the figures it cites for churn reduction are vendor claims we could not verify.
Wrong for
A European buyer who needs a documented data region before talks start, or a team of two that wants a lightweight tool.
Visit ChurnZero →
#8 HubSpot Service Hub
CRM-native customer success workspace · United States · hubspot.com
Published prices Free plan Inside HubSpot CRM
HubSpot Service Hub is eighth because the biggest names are held out of the top three and because it is a workspace, not a stand-alone platform.
- Pricing: Per seat / month. Service Hub lists a free plan for up to 2 users, Starter from $7 per seat per month, Professional from $90 and Enterprise from $150. Free plan: free plan.
- Best for: HubSpot customers with small CS teams
- Strengths: Customer Success Workspace; Health scores; Help desk.
Where it falls short
The workspace is not on the free or Starter tier, and per-seat Professional pricing adds up for large teams.
Wrong for
A company on Salesforce or another CRM, or a team that needs deep renewal management and product usage scoring.
Visit HubSpot Service Hub →
#9 Totango
Customer success platform now branded Odie · United States · totango.com
Quote only EU region available Catalyst merged
Totango takes ninth place because the product line is in flux. The homepage now says Totango has rebranded to Odie, a customer knowledge engine, while still listing Totango as a customer success platform and Catalyst as a customer growth platform.
- Pricing: Quote only. No prices on the pages we fetched; its pricing URL returned an error and the homepage points to demos. Free plan: none.
- Best for: Teams wanting EU hosting from a US vendor
- Strengths: Customer success platform; Catalyst growth platform; Odie knowledge engine.
Where it falls short
The rebrand, the Catalyst merger and a separate Odie product make it hard for a newcomer to know which product they are buying and what it will cost. Pricing and trial terms are not on the pages we read, and the headquarters address is not stated in its policies.
Wrong for
A buyer who wants a stable, single-brand roadmap and published pricing from day one.
Visit Totango →
#10 SmartKarrot
Customer success platform with published entry plan · United States · smartkarrot.com
Published entry price Tiers by users and products Outcome-based option
SmartKarrot ranks tenth. It is one of the few vendors to print a number: Basic is listed from $15,000 a year with 5 users and 2 integrations, Growth has 10 users, 1 SaaS product and 3 integrations, and Pro has 25 users, 3 products and 4 integrations.
- Pricing: Quote only. Basic from $15,000 a year with 5 users and 2 integrations. Free plan: none.
- Best for: Mid-sized teams wanting an annual price
- Strengths: Customer 360; SmartPlaybooks; Health scoring.
Where it falls short
The $15,000 entry price is above what a very small team can justify, and Growth, Pro and Enterprise require a call. Several useful modules are paid extensions.
Wrong for
A European company that needs EU-only data hosting, or a team with a budget well under $15,000 a year.
Visit SmartKarrot →
#11 Staircase AI
Conversation analysis for churn and expansion signals · United States · gainsight.com
Gainsight-owned Zero data entry ISO 27001 and 42001
Staircase AI ranks eleventh because it covers one layer of the job rather than the whole platform. Its page says it analyzes emails, support tickets, chats and meetings to surface churn risk, expansion opportunities and disengaged stakeholders, with no manual logging, and about an hour of setup. It lists ISO 27001 and ISO 42001 certification, PII anonymization and role-based access.
- Pricing: Quote only. No prices on its page; visitors are directed to schedule demos. Free plan: none.
- Best for: Teams wanting signals without manual logging
- Strengths: Email and ticket analysis; Churn risk signals; Stakeholder disengagement alerts.
Where it falls short
It is owned by Gainsight, now sits on gainsight.com, and the old staircase.ai domain redirects there, so independence from a large vendor is limited. No pricing or trial is published.
Wrong for
A team that needs a full customer success workspace in one product.
Visit Staircase AI →
#12 Churnkey
Cancel flows and payment recovery for subscriptions · United States · churnkey.co
Priced by churned revenue 14-day trial Open-source SDK
Churnkey is last because it solves a narrower problem than a customer success platform, though it does so with the clearest pricing on the list. It prices by average monthly churned revenue across four tiers, fixes the price for 12 months, offers a 14-day trial without a card on Starter, and includes an open-source SDK on all plans.
- Pricing: Usage-based. Four tiers priced by average monthly churned revenue, Starter in the low hundreds of dollars a month, Core and Intelligence higher, Enterprise custom. Free plan: free trial.
- Best for: Self-serve subscription businesses
- Strengths: Cancel flows; Payment recovery; Customer health scoring.
Where it falls short
It does not manage accounts, renewals, success plans or onboarding, so it cannot replace a customer success platform. Pricing per churned dollar means the bill rises with your losses.
Wrong for
A B2B company selling six-figure contracts through account managers, where churn is a relationship problem.

Questions and answers
What is the best customer success software in 2026?
Custify ranks first of 12, best for saaS teams of 2 to 15 CSMs. ClientSuccess is second (small and mid-sized B2B teams) and Velaris third (mid-market and enterprise SaaS in the UK and EU). Places 1 to 3 go to challengers, vendors outside the best-known brands, wherever the category has them.
Do I need customer success software, or is my CRM enough?
A CRM is enough while one or two people know every account by name and renewals are few. Once health depends on product usage, support volume and billing together, the CRM becomes a place where someone types notes.
How much does customer success software cost?
Most vendors publish no figures. SmartKarrot lists a Basic plan from $15,000 a year with 5 users and 2 integrations. HubSpot lists Service Hub Professional, which includes its customer success workspace, from $90 per seat per month.
What is the difference between Gainsight and ChurnZero?
Both are US-built platforms for health scores, journeys and renewals. Gainsight sells a wider family: customer success, Skilljar academies, product experience and communities, plus Staircase AI, sized by full users and customers per user.
Is a free customer success platform worth using?
Rarely for the core job. Among these twelve, HubSpot is the only vendor with a published free plan, and the customer success workspace is on its paid Professional and Enterprise tiers.
What happened to Catalyst and Staircase AI?
Catalyst's own site says it was acquired by Totango and now operates as a Totango product, and Totango's homepage lists Totango, Catalyst and a newer product called Odie.
Where is my customer data stored with these tools?
It varies. Custify states data is stored in Germany, Totango's privacy policy lists AWS North Virginia and AWS Germany, Velaris says personal data is stored in the United Kingdom, and Planhat offers EU or US hosting.
Can customer success software predict churn?
It scores risk from signals you feed it, such as logins, feature use, ticket volume, overdue invoices and champion changes, and several vendors now add AI that reads emails and calls.
How long does implementation take?
ClientSuccess says typically 4 to 6 weeks, and Staircase AI says value starts after roughly one hour of setup because it reads existing communication channels.
Is Churnkey a customer success platform?
Not in the classic sense. Churnkey focuses on subscription cancel flows, failed-payment recovery and reactivation, priced by monthly churned revenue.
How often is this ranking updated?
We re-check vendor pages, prices and ownership changes on a rolling basis and revise the order when something material changes, such as an acquisition, a new pricing model or a change in hosting.
