16 Best Customer Success Tools & Software for 2021

Our round-up of the best customer success tools to integrate into your tech stack.

By Geoffrey Keating

A robust customer success program is practically a recipe for growth. When you provide your customers with the support they need to achieve their desired outcome, your success and theirs go hand in hand.

Supported by the right customer success tools you and your team will be able to predict churn, reach out to customers at just the right time, improve retention, increase new sales and upsells, and a lot more. Taking care of all these tasks is a lot of work, though. And how your team goes about them will change as your business grows.

Choosing the right customer success tool isn’t enough. You need to select your tools with an eye for your larger “customer success stack,” which will grow, shrink, and adapt to the ever-changing needs of your customers. 

What are customer success tools? 

Customer success tools refers to a broad category of tools that help businesses improve the customer experience and harness their customer data for actionable insights. These can include:

  • Live chat tools

  • Customer health and feedback tools

  • Analytics tools

  • Tools for reducing churn

  • CRMs and help desks

To get started, we decided to round up a list of the best customer success software solutions, which we’ve split into the categories laid out above.

Live chat and support tools

It’s important to meet your customers where they are, whether that’s on your website or in your product. Live chat tools have become one of the most relied on tools for interacting with customers when they need it.

This reliance is for good reason because, according to a 2013 study by Econsultancy, live chat has the highest level of satisfaction for any customer service channel. With the right live chat software, you can easily boost customer retention and satisfaction. Here are a few options for live chat and live support customer success tools:


Drift is a live chat tool that can go on your website or within your product. Its focus is on sales and revenue generation, but it does have customer success capabilities.

Intercom is great for:

  • Growing teams that need a more robust live chat platform that can grow with them.

Here are some tools that’ll help you do just that:
