Excited to announce Concentrate AI’s $5.1M pre-seed!

Todd Lieberman and I are launching Concentrate AI (the fifth company we've started together).

Most companies are not in control of their AI spend or the data they’re sending to AI.

@concentrateai solves that.

Why are we building it? What problem does it solve? And why now?

@Lambda_World @iteratorshq It was a pleasure! See you next year!!

[Voytek Pituła 💙/💛/🖤 @Krever01]

Scala — great, beautiful language. Strong types. Very strong. OO, FP — does both. Nobody does that. Pattern matching? Best ever. Case classes — everybody loves them. Fast, safe, smart. People switching. They say, “I want Scala.” It’s winning. Total winner. People call me, they say, “Sir, you were right about Scala.” I know. It’s what America needs

Scala Projects Maintenance Survey results, still fresh from the oven are there! With over 100 responses from tech leaders and managers from our community to shed some light on how Scala fares. We shared pieces of results earlier, and it started a discussion - so we hope that we as a community will be able to learn and improve. We are aware that this survey isn’t perfect; it has blind spots - but it is better to reason based on some results rather than base your judgments just on one’s feelings and experience -  no matter how vast it is.
