Product Dev. Sometimes your best product shots come from the community. Another reasons to release early, often & be generous with the samples you send out! Picture is summer 2021... #buildinpublic #climbing #chalk

One of the first things we tried out at Chalk Rebels was to make liquid without magnesium carbonate We settled on modifying an anti-perspirant. We did many rounds of formulations until we ended up with Crystal Chalk. First samples looked like this #buildinpublic #climbing #chalk

Product Dev. We wasted so much time early on designing cardboard boxes for our chalk products. In the end we just started shipping tubes without box at all. Box design printout, probably summer 2020. #buildinpublic #climbing #chalk

Be our hero. Help us switch to Upsalite®. It's a magic kind of chalk that performs 10 times better than regular chalk. Today we already use Upsalite®. But only for liquid chalk. And you can HELP US BRING UPSALITE® TO CHALK POWDER. #buildinpublic #upsalite #climbing #chalk

Chalk Rebels Flashback. This is how chalk gets shipped at scale. It comes in 25kg bags before we process them into liquid chalk. This one is from summer 2021. #buildinpublic #climbing #chalk

Product Dev. It felt really weird to go back to dry chalk when I started to test our latest product line in Autumn 2022. Tested about a dozen different blends before setting on two awesome formulas with Upsalite®: smooth & chunky #buildinpublic #climbing #chalk

Product Dev. We ordered tons of these boxes for our first production run and ended up discarding lots of them because guess what? Turns out retailers don't want boxes, they suck for shipping. Chalk is about putting tubes on shelves. Much easier! #buildinpublic #chalk #climbing

Product Dev. "I swear officer, this is not what you think it is ..." You end up doing all kinds of weird things to prototype chalk packaging. Walter White would be proud. New packaging prototyping summer 2022 ... #buildinpublic #climbing #chalk

Okay ... now my eyes definitely are starting to glaze over ... editing the Kickstarter rewards for our Upsalite® Chalk campaign ... #kickstarter #climbing #chalk #buildinpublic

Product Dev. Even before settling on liquid chalk as a first product we experimented with chalk balls. In the summer of 2019 we experimented with paper packaging. This is a first prototype shoot from summer 2019 #buildinpublic #climbing #chalkball #chalk

Product Dev. Early box prototype for our chalk. 2020. Turns out retailers don't want boxes: "Just give me a tube I can stick on a shelf." and we changed the color ... and ... and ... if you don't make mistakes you're not learning ... #chalkrebels #chalk #climbing #buildinpublic
