Buying Considerations for 6sense Competitors

As you weigh 6sense against competitors, there are several things you need to consider before picking the best option. Let’s take a closer look at some of the most important factors to evaluate during your search:

• Data Coverage & Quality – Note the kind of data that each platform offers. In addition to knowing the type (email, phone number, job title, etc.), you also need to know what part of the world the data comes from, how accurate it is, and how much data its database actually contains.

• Integrations – If your sales or marketing teams use other tools, it’s essential to select a platform that integrates seamlessly with them. If you don’t make this consideration, you may end up using a platform that doesn’t play well with your existing tools, which is sure to lead to a lot of frustration.

• Budget – Some revenue intelligence platforms are reasonably priced enough for even small or new businesses to afford, whereas others are reserved for companies willing to spend a fortune to access the right data. Find a solution that lines up with your monthly budget.

• Implementation – Ease of setup and deployment  is another important consideration. If a tool is challenging to set up, the onboarding process may be frustrating, require more training, and take more time away from your team than if you had gone with something simpler.

• Ease of Use – After deployment, the tool should also be easy to use. The easier a tool is to operate for everyone on your team, the shorter the learning curve is and the more likely your team is to use it without fuss or error.
