Understanding Data and User Behaviour to Encourage Sustainability Through Technology

mymizu co-founder Mariko, getting a free water refill at on of our volunteer refill partners

Tell us a bit about mymizu. What behaviour are you trying to get your users to adopt?

Our founders wanted to reduce the use of single-use plastics since it was the main source of plastic waste, so we started using open-source information on the location of free water refill sources like water fountains, to create maps of where they were.

How did you translate the founders’ mission into a product vision?

The first thing I did was to have open and honest conversations with the team to map our vision and what we would do from a product perspective to achieve that.

How does this differ from large commercial enterprises?

My experience in larger commercial companies is that the metrics are very business-focused. It can be hard to stay true to the original mission of the company from when they started decades ago.

What features did you build to encourage users to build a habit of using water refills?

Initially, users only opened the app when they wanted to find a refill spot or they remembered to track that they did a refill that day. People had no reason to open it on a daily basis and they just forgot about it.

What are some of your future plans for the product?

We think that the maps of refill spots could also be used in different ways. For example, it’s a great way for users to discover cafes and restaurants that share the same sustainability beliefs as they do. Since we want to exponentially increase our refill partner network. We may also start gathering data around how users are interacting with the refill spots, to track the impact/footfall of mymizu users towards local business. For example, how many mymizu users are visiting certain cafes, are they supporting the cafes by buying things or sharing them on social media, etc.

Lastly, how important is it for a startup to think about data and metrics?

Many founders are too busy running the company, (rightly so), to sit and play around with data to understand what’s going on with the product, and how they can leverage these insights. They’re sometimes not sure how much it helps especially when the startup is building in a very agile mode.
