I built the LLM interface I wished existed. interface0 is for power users: cross-provider memory & chat, multi-model synthesis, sharing & team features, granular context engineering, template prompts, forking, prompt enhancing, & more Here's a demo—see 🧵 for the rest

Copycats are usually subtle. But Eco has one that isn’t. Imagine a company spent all day copy-and-pasting *everything*... ...while raising from investors like Y Combinator and Eniac Ventures (who I bet have no idea) Well, we tracked it all. I’ve never seen anything like it 👇

Restaking / shared cryptoeconomic security like @eigencloud is fascinating. And it's happening in Bitcoin too (w/ work, not stake). Looks like @Coredao_Org has quietly gotten >35% of *all* Bitcoin hash rate delegated according to stake.coredao.org

And now: back to building that beautiful open system I talked about, and putting our community's money back to work for them. More to come soon (and, uh, presumably get immediately copied). Check out Eco Explore III if you want to see the latest. ✌️ eco.com/explore

*The* Fundraising book is now out and is a must-read for anyone trying to raise capital. I’ve seen this advice help founders raise $100MMs (incl. us at @eco!) 👉 It’s so good that I'm giving away 100 FREE copies. retweet & like this Tweet and follow @ryantakesoff to claim! 👈

3. Every company takes inspiration from competitors and stands on the shoulders of giants. But to me, there is a line. It may be hazy. But the copy-and-pasting, immaturity, lying, and espionage in this thread crosses it. And when that line is crossed, it needs to be called out.

Their site just went up, and there’s *so* much more 😳 They stole our blog posts. They stole our marketing copy. They copy/pasted our T&Cs and Privacy Policy. They copied our funnel questions. They stole our idea of checking if users have Metam*sk. There’s too much to post.

But others either got caught by the copycats or turned a blind eye. @ycombinator @eniacvc @nihalmehta @anthonyha @RichLightShed @JamieLightShed @montageventures @thehousefund @global_founders @ericbluewatch @obj @leoreavidar @MattBellamy +more I hope and believe it’s the former.
