Adam Diehm explains how he reliably generates $150/mo from a simple tool he built to help people manage their data.

Tell us about yourself and what you're working on.

My name is Adam Diehm and I am a web developer, SEO expert, and entrepreneur. I own multiple businesses as well as a number of web projects.

My project is used by SEO experts, developers, and many other people who are looking to convert data to/from columns and comma-delimited lists.

How'd you get started with

I initially built the product for myself, because I had many clients emailing me spreadsheets of data and wanting reporting from their web applications. I was working as a dev at my agency at the time, and I developed the main functionality myself, with help on layout and feature-additions coming from my staff as well.

I figured others could use something with my tool's functionality, too, so I put it online at My initial goal was that it might make a few bucks and get a couple hundred users. However, today we are a factor of 10 better than my initial expectations in both usage and revenue.

How long did it take you to build it?

There were about 20 hours invested in the initial release, and there've been at least 50 hours of ongoing development — adding advanced features and tweaking various things.

How have you grow your user base and revenue over time?

I started the project in the middle of 2014, and we began making money from day one via Google AdSense.

New users find us every day via SEO, as we are the top ranking tool for most related web searches. We get around 80% of our overall usage each day from returning users. So as new users find the product, our overall usage grows. We consistently see 10% increase in usage month over month.

I also get significant feedback and shares/mentions on Twitter, which are always nice to see.

If you had to start over, what would you do differently?

Nothing. The project really is what I thought it would be. It's a useful tool that's popular due to its simplicity and ability to handle its single purpose.

I am planning to launch a wide-screen design tweak, and will do a full re-design in 2017.

Where can we go to learn more?

You can find me on Twitter (@atdiehm) Twitter and Facebook. I like to consult on user acquisition and monetization for online businesses/startups, as well as do MVP work for the same. I share pictures of great beer on Instagram as well.
