How Maciej acquired customers
Tools used to build Calendesk
Maciej Cupial from Poland had a background as a programmer and entrepreneur. After a challenging 2.5 years building Calendesk, he finally reached $100K ARR.
The journey wasn't easy - he burned through savings, went bankrupt, and even had to work for others again before getting there.
SEO became his main channel, though it was slow to see results. Being based in Poland with a less crowded market gave him an advantage.
Entrepreneurship is a rollercoaster - be prepared for extreme ups and downs
First marketing attempts may not be profitable but provide valuable customer insights
SEO is slow but worth the long-term investment
