So pumped to build this future with this amazing team! I joined @coframe a month ago to build what we could only dream of at Optimizely: website optimization that’s continually learning and improving itself
The internet is dead. We’ve raised $35M total funding led by Khosla and Hanabi to bring it to life.
@coframe is a growth engine for your website/ads/more which tests, personalizes, & learns 24/7.
It’s working. Dropbox increased conversion by 158%. Replit, 410%. Cash App, 60%.

Ever get asked for a quick “vibe check” ie customer input to help make a decision? I did the other day, and my default is to set up a few calls with customers to get their reaction.

I wanted to brainstorm faster and cheaper methods, but we don’t have a researcher on staff. So I turned to the next best thing: my expert AI researcher, Research Mate: research-mate.replit.app/

Writing clear, un-biased, non-leading interview questions was a big source of hand wringing for me when forming research plans. I'd spend WAY too much time refining my questions and editing them and reviewing them with colleagues to make sure I was asking good questions

But no more! This was my original use case for Research Mate: feed it interview questions, and it will remove bias, re-word leading questions, streamline the structure, and make sure your script is tight and getting you accurate insights. Try it yourself: research-mate.replit.app/doc…

I love collaborating with an experienced UX researcher to help me hone my research plan and interview script. They sharpen my thinking, help me hone in on the right method to use, and improve my interview questions.

Just posted my 2024 reading list. I read half as many books this year as last, but for some very good reasons that you can learn about in the post. jlzych.com/2024/12/31/2024-r…

Don't let a linear design process snuff out your sparks of inspiration. I've learned over the years to follow my inspiration when it strikes, rather than going back to the beginning of the double diamond to work through projects. jlzych.com/2024/04/12/don-t-…

I'm taking the next step in my career to build a company of one! 🥳 I'm going freelance, focusing on designing technical and developer tools. I wrote more about why here: jlzych.com/2023/05/06/taking…
For anyone who's interested in improving their visual design skills, I collected a bunch of resources that have helped me improve over the past few years: jlzych.com/2022/04/10/how-i-…

Been building the workflow builder since last summer with @muffinbutme and @lexiberylross . So exciting to see it fully rolled out to everyone (yes, using a workflow we built)! @LaunchDarkly launchdarkly.com/blog/easy-f…

I often see product designers immediately reach for the components in their design system upon entering the solution exploration phase. Don't. Learn why and what to do instead: jlzych.com/2021/05/22/when-i… #productdesign #designsystems
