The best thing about Zealous is that they are very approachable, do their homework and can tell you what will tick at the very first meeting.

James also made it a point to send me detailed working notes and followed up on the progress made soon after. I highly recommend their services to anyone that needs it.

We dramatically improved SaaS startup ExpenseIn's CPA and rocketed their digital marketing results.


ExpenseIn is a software as a service for businesses who need an easier way to manage expenses.

We worked closely with their team to develop and execute a strategy that would help them reach the right audience and convert more of them into customers.

We worked on:

  • Audience research
  • Copywriting
  • Website design & development
  • Paid Ads
  • Ongoing solutions in response to evolving customer needs 

The result is a fully responsive site that intertwines their existing brand identity, compelling content, and focused calls to action in a fresh aesthetic. And it was launched in less than six weeks.

But even more importantly this collaboration has resulted in vast improvements to ExpenseIn's cost per acquisition and has helped prove to investors that ExpenseIn is a serious opportunity.


Increase in positive interations of over 96.9%.

Increase in trial and demo conversion rate of over 87.8%.

Increase in organic search traffic of over 31.5%.

We worked closely with James from Zealous Digital throughout the development process. He readily considered our needs and suggestions, while applying his own expertise to amplify impact.

This resulted in a stunning site that projects our values in a way that every member of our team loves.

We look forward to working with Zealous Digital again in future projects.

The first 15 minutes is all about you. I want to hear about your business, story and dreams. 

Next comes the most important part of your business: your customers. You'll teach me all about your customers and the problems that you solve for them. Keeping your audience at the centre of our process is essential.

Next we'll talk a bit about what's been working so far before transitioning into strategising ways to make your dreams reality and overcome barriers to growth.

It's not uncommon to come away with many pages of notes. You're going to have a big, but incredibly useful, to-do list no matter what stage your business is at!

Now that you know a bit about us, I'd love to have a few details about you. But keep it simple for now.

In about a tweet, give me an introduction to you, your business and your purpose.

Don't worry, we won't share your information.

I’ve been fortunate enough to work with Zealous Digital twice. Both times I had tough website technical issues and James was able to get them sorted out, same day.

Would highly recommend this company and will use again in the future.
