28 Best Growth Hacking Tools for Marketers [Most Are FREE]

So you’re ready to grow your business, and you want to do it fast. Do you know the growth hacking tools that’ll help you to reach your goals? There are a lot of business growth tools and apps out there, and sometimes it’s hard to know which are the most useful.

That’s why we’ve done the hard work for you, collecting the essential tools to help you execute your business growth strategy at every stage of the growth hacking funnel.

What’s the growth hacking funnel? It’s a way to visualize the different stages of interaction with your customers. The growth-hacking funnel consists of:

  • Acquisition
  • Activation
  • Retention
  • Revenue
  • Referral

These are also called “pirate metrics” because of their initials (AARRR).

To keep things simple, we’ve segmented our list of growth tools according to the stages of the funnel. Use the table of contents below to jump to the section where you’re looking for some help and inspiration. By the end, you’ll be able to add some cool growth hacking tools to your must-try list.

Growth Hacking Tools for Customer Acquisition

Some of the best growth hack techniques focus on innovative ways to get new customers. That makes sense because you need new customers or users if you’re going to grow. Here are the business growth tools we recommend for this stage of the growth hacking funnel.

1. OptinMonster Exit-Intent®

We’re confident in putting OptinMonster first on the list because it’s got so many features that make it a great all-around tool for growth hacking marketing.

One of the most important ones for customer acquisition is our proprietary Exit-Intent® Technology. Exit-Intent® detects when visitors are about to leave, so you can grab their attention with a targeted offer, message, or lead magnet.

Travel site Anywhere.com used exit-intent popups to recover 56% of abandoning visitors and turn them into subscribers and customers.

exit intent popups are one of the most powerful growth hacking tools

You can combine Exit-Intent® with page-level targeting to create highly targeted campaigns that are personalized to your website visitors’ interests. For example, you can create specific offers based on the content the reader is interested in, or display a special message only to visitors from Facebook.

These highly targeted campaigns are incredibly effective. Check out how Kennedy Blue used exit-intent popups to lift sales by 50%.

Add to that our integrations with the leading email service providers, CRM software and eCommerce platforms, and you can see why OptinMonster’s one of the best growth hacking tools around.

2. Constant Contact

Just tripped over the 2000 subscriber mark – or starting out with a large audience? Another great growth hacking tool for email is Constant Contact, which is at the top of WPBeginner’s list of the best email marketing services.

Constant Contact is great for people new to email marketing, with extensive online training, a huge resource library, and even local webinars. Their support is second to none and includes email, live chat and an active community of users.

3. Mailchimp


Email marketing is a core growth hacking strategy, and at a $40 return for every dollar you spend, you can’t beat the ROI. If you’re a budget-conscious business – and what business isn’t? – then Mailchimp has got to be included in any list of growth hacking tools.

Why? For a start, it’s free for up to 2,000 subscribers or 12,000 emails a month, which is more than enough when you’re starting out. Mailchimp also has a great email creation wizard, lots of templates, and even email workflows to help you get started. Plus, there’s a wealth of information in their knowledgebase.

4. ManyChat

Facebook messenger bots are all the rage, and for good reason. Marketers have seen incredible conversion rates from Facebook messenger marketing.

But monitoring your Facebook messages for your business can be time-consuming. If you want to see results like that, without spending all your time chatting, try creating your own bot to deliver customer service and support and win business even when you’re not online.

ManyChat integrates with Facebook Messenger. It lets you create your first bot for free, with a drag and drop interface which means you don’t need to know complicated code. Once that’s done, your bot can keep your business in touch with potential customers 24 hours a day.

Growth Hacking Tools for Customer Activation

Next, let’s move on to customer activation. The growth hacking tools in this section aim to get customers to use your product. Of course, the email marketing tools listed above can also achieve this with the right marketing campaign, but here are some more tools to try.

5. UserLane

growth hacking tools - userlane is a good option

UserLane calls itself a “navigation system for your software”. In other words, shows users the basics so they can start getting results fast. With this software, you can create an interactive onboarding guide, that rewards users with a checkmark every time they successfully complete a step. When users are able to enjoy success from the start, they’re sure to want to stick around.

Gamification is a proven growth hack, so this one’s worth checking out. They’ve also got a special plan for startups.

6. Consumer Barometer

Understanding your customers helps with every stage of the growth hacking funnel, and that includes activation. Luckily, Google has partnered with other organizations to provide Consumer Barometer, a free tool which delivers insights on global consumers.

You can find out about how consumers research and purchase products and services in different countries and what devices they are using. This information can help you target your marketing throughout the customer relationship.

7. Google Analytics

growth hacking tools - google analytics

If you want to activate your new customers, knowing what’s working for your existing ones is a smart strategy. That’s where analytics tools come in, and Google Analytics is one of the most widely used. That’s not just because it’s free; it’s also because you can get in-depth data on your visitors, their behavior, and conversions to drive more growth.

Google Analytics can help you to understand user flow, and identify and eliminate the bottlenecks that are preventing visitors from getting the most from your product or service. And if you’re looking for an easy way to access your analytics data from the WordPress dashboard, try MonsterInsights.

8. YouTube

2018 growth hacks - use youtube

If you want your customers to use your product, show them how it’s done. As mentioned above, gamifying onboarding is one way to do this, but another is to use video. That’s why YouTube is on our list of growth hacking tools.

According to our roundup of video marketing stats, not only does video drive leads and sales, but YouTube inspires trust. Plus nearly 80% of consumers would rather watch a video than read about a product. Since YouTube is free, there’s no excuse for avoiding it, so try including some onboarding videos to help with customer activation.

Growth Hacking Tools for Retaining Customers

Customer churn is a fact of life for many companies, but you want to keep that rate down and retain as many customers as possible. This next set of growth hacking tools will help you to do that.

9. CoSchedule Headline Analyzer


One of the easiest and best growth hacks to attract and retain customers is to use content marketing. And the success of most content marketing relies on having an appealing headline.

That’s why CoSchedule’s headline analyzer is a growth tool. Plug in your headline, and you’ll get a score from 0 to 100 that measures its appeal. The free analyzer looks at your use of power words, emotional words, and uncommon words, and assesses length and readability.

Write better headlines and you’ll get more customers reading your content, giving them more reasons to stick around. And when they share your content, you’ll attract even more leads.

One secret to retaining customers is to connect with them where they are. That’s why Facebook, with a global audience of more than 2 billion, is a great place to start.

One of the easiest ways to reach customers is with Facebook Messenger, the social site’s messaging platform. That’s because you can connect with customers on the smartphones that go everywhere with them, and answer their questions almost immediately.

As we saw earlier, bots are a great way to maintain a continuous connection with customers. In addition to ManyChat, mentioned earlier, you can build bots with ChatFuel, Botisfy, and many others.

14. Reddit

reddit is one of the best growth hacking tools

Reddit, which calls itself the front page of the internet, has communities (called subreddits) for everything. That’s not an exaggeration: there are hundreds of thousands of them. That makes Reddit an excellent place to find and talk to your target customers for free. Slidebean shared its blog content in relevant communities, getting in front of thousands of prospective customers, and considers the site one of its top growth tools.

15. Quora

Quora is another place to learn what your customers are asking so you can provide the answers they need.

Best of all, when you know the questions that are asked on Quora, you can use them to flesh out your content marketing strategy with blog posts and other resources.

16. Mention

use monitoring as a social media growth hack with mention

While there are lots of webinar marketing apps you could use, we’re recommending Zoom. It’s free for up to 40 minutes and up to 100 participants, and you can use it for meetings too. Plus you can record your webinar to use as a lead generation tool later on.

19. SEMrush

Growth Hacking Tools for Getting Customer Referrals
