What our clients say

Hashtag Company did not disappoint. Our website looked exactly like what we briefed them on: it’s responsive and it’s set up with everything a digital agency needs, such as all Google Analytics essentials and pixel tracking.

The service Woei-Sang provided was professional, super quick, streamlined, and zero hassle to us. We’re a busy agency so we’re not always super responsive when it comes to our own stuff, but Woei-Sang only ever came to us for essentials such as revisions.

He basically presented us with a brand new, on-brand, perfectly executed website, not to mention a one-on-one coaching all in which he made it super easy for us to edit anything in case we needed to.

Last but not least, Woei-Sang is a delightful human being, who has a true knowledge and passion for his field, and is always ready to go above and beyond. THANK YOU!!

I’m very happy with results that Hashtag Company delivers. They really understand our goals and translated these to the website and online marketing campaigns. Their team is very professional and always quick to answer when you need them. It’s a pleasure to work with them.

With Hashtag Company you can count on preparedness, professional knowledge and alot of friendliness. When I came in contact with them I had a half baked website with a lot of question marks, but with a lot of patience and the much needed expertise, they turned it into a beautiful online magazine.

What I really appreciate is that they are very responsive and always respond to my questions and feedback within a day, which is not always the case in this industry. So only positive experiences for me!

I am jumping for joy because Woei-Sang was able to help me recover my header and navigation after I accidentally deleted it. I had hired someone locally to help me after this big mistake happened, and after several hours, she was not able to retrieve it.

It was an expensive lesson for me to learn, so now I will only work with parties like Hashtag Company that is experienced and truly knows WordPress inside out!

Because of our long term cooperation, I’ve asked Hashtag Company to develop our website and take care of a part of our online marketing.

Hashtag Company listens to our own input very well to make sure our ideas are translated to the online world. They’re also very involved and engaged in every step of our company.

Hashtag Company helped me with my website when I just started my own business. Woei-Sang is a friendly conversation partner, thinks along proactively with me and comes up with creative ideas. He’s also an expert in the field of digital marketing. My website has been completely redesigned recently and I’m very happy with the result as it fits perfectly with me and my company.

That’s why I highly recommend Hashtag Company! They take the time for their customers, act fast, always teaching, listen to the needs of their customers and deliver a beautiful end result.
