The new standard in EU VAT Validation

No Employees

Solo Founder

Built and struggled with EU VAT rates and validation. Had to build it from scratch, since other solutions on the market that handle this are either very expensive for what they do or hard to implement.

March 27, 2021 ProductHunt Launch!

Very very nervous, but finally launched Vatfy on ProductHunt. I would be super happy, if you guys could share some love over at ProductHunt. Here is the link:

This is my very first launch external of IndieHackers, and since most of you think fondly of ProductHunt, I figured: why the hell not?

March 12, 2021 Being high on booked meetings

After the soft launch of Vatfy, I started to reach out to my closer network. Friends, family, ex-colleagues and mentors.

Resonance was fantastic.

They get the product. They understand what I do. They even made some intros to people they think would benefit from what I have built with Vatfy.

The first intro I got, I immediately booked a meeting.

Now fear kicks in.

I have never done BDR/SDR work.

Should I prepare a demo?

And if yes, how do I demo an API?

Should I prepare a Slide Deck?

Should I sell Vatfy?

What is expected of me at this point?

Just listen to what the potential client wants/needs?

Perhaps I am overthinking this, but I'd love to go in prepared.

Any pointers?

March 10, 2021 Public Soft-Launch!

It was about time to reach my even bigger milestone for Vatfy. Today, I finally released Vatfy publicly!


A lot of sweat, tears and migraine attacks were necessary to get Vatfy where it is today and after some valuable feedback from testers, I pivoted some aspects of Vatfy to accommodate my testers insights.

I present you:

Usage of Vatfy is free and you do not need a credit card to sign up for it. The free plan comes with some minor limitations, but for the moment I do not enforce these limits (which I might do in the future).

I would love some feedback!

December 17, 2020 Vatfy launched. Now I am nervous.

Big big milestone today. I officially removed the Basic Authentication from and we are thus now live.

Not finished though, since some features are still missing, documentation is not final and unpublished. Also, payment options are still in sandbox mode not live yet. BUT, we are live. And I encourage all IH members to check it out.

Since this was a project born on IndieHackers, I will make this free for all IndieHackers, if you all keep its use reasonable.

Just upgrade to the paid plan with the sandbox creditcard:

Card 4242 4242 4242 4242
Name, Date and CCV enter whatever you like. For name, just add "IH", so I know which ones are coming from here.

For now, go for it. Test it, I am eager for your feedback.

November 30, 2020 Vatfy Dashboard finished

Another milestone reached. The Vatfy Dashboard is finished. Well, sort of. The only thing missing at the moment is a history view on past validations, calculations and rate requests delivered through the API for each user.

And, of course, I need to writing some documentation and an onboarding wizard for first-time users. This however is harder than I thought. With limited feedback, I have limited questions to has been asked so far. So not sure on what I should put into the FAQ/Support section.

Beginning in December 2020, I will open up registration to IndieHacker members for free. So all of you, which are interested in the platform, are able to give it a spin. Hopefully supplying me with valuable feedback. Good or bad.

October 15, 2020 Vatfy API finished

Well, after having this project on my backlog of things to finish, I finally completed the API. Unfortunately, I scraped the dashboard, the pricing, the signup, basically everything and started completely new and from scratch.

It just felt good.

The old code got bloated and I lost track at what Vatfy should be really about. The core. The essence of it.

So as of today, I can proudly say: the Vatfy API is done and ready.

Any testers out there that want to help me and provide some feedback on what you'd like to see on the dashboards of Vatfy?

PM me. I'll give you access.
