I think the next gen of employee- first companies will be wfh centric (or something new and flexible) and 4 day work weeks. People realized slides and food wasn’t as good as free time and flexibility. I expect maxing their employees 401ks and generous cultural WLB.
Companies that are advancing technology and gaining a rep as tech first? Look at blog posts that gain lots of traction here: Fly.io, Cloudflare, and many others. etc. Avoid anything too trendy ( AI, blockchain) because they might not last the hype cycles.
