Could we be co-founders?

My strength is product and engineering. If yours is sales, marketing or running a business, we could be a good match.

I put a huge amount of time into what I build and enjoy working with people who bring that same intensity.

We can get to know each other first and decide what to build together.

Let's talk

A little about me.

I'm Siebe. I live in . I taught myself to code and I've been building products ever since. Coinz showed me what it takes to grow something to over a million users. Enkryptify showed me how to raise money and what it feels like when a company doesn't work out.

I build every day. What I enjoy most is taking something complicated and making it simple enough to feel obvious. I want a co-founder who is as serious about the business as I am about the product.

Away from my laptop, I spend a lot of time at the and love going .
