And a huge thank you to my co-founder @colegawin_ and the Lemma team for getting us here today. To our families, friends from USC, and mentors who supported us before there was anything to show: this one's for you. 14.1K views · 31 likes · 0 reposts · 1 replies Open on X →

Production traces are the clearest record of how agents behave, but you shouldn't have to dig through them manually just to learn how your agent is failing. Book a demo → https://t.co/63Lh9seDyv 15.8K views · 31 likes · 0 reposts · 1 replies Open on X →

We spent months embedded with agent teams, sitting inside their production traces, watching how agents actually fail. Now, Lemma processes 1M+ agent conversations a day, trusted by some of the fastest-growing agent startups (Modus, Boardy, Stan, Lucis, Folk + more).

Shipping the fix isn't where it ends. Lemma watches for the same behavior in production. If it regresses, you'll be the first to know. https://t.co/2ws6Xq4zOj

If it needs a fix, Lemma hands your coding agent everything it needs, the traces, the context, the failure, so the fix is one prompt away. https://t.co/vlQw66u7ls

When an issue becomes urgent, Lemma pings you on Slack. From there, you can see what happened, pull the relevant traces, and decide whether it needs a fix. https://t.co/CvliurKXyD

Here’s what that actually looks like. Lemma watches production runs and surfaces failures you didn't know to look for… we call them issues. https://t.co/YxUSJD6KB4

Agents are taking on real economic work. As runs get longer, mistakes become expensive at best, catastrophic at worst. Today, teams find out from user complaints. Or never. Monitoring tools only catch what you told them to watch for: you set up the judges, you trace the issues 52.6K views · 153 likes · 0 reposts · 6 replies Open on X →

Agents f*ck up. We raised a $2.3M pre-seed to warn you before it’s too late https://t.co/VXplPObX6v
