Excited to announce that we co-led a $16M Series A for @sequen_ai, the world's first behavior design engine for the enterprise. Sequen enables consumer companies to deliver real-time, in-session personalization by training on live user behavior and making sub-second ranking decisions - driving real revenue lifts. I'm so grateful that we at @thresholdvc get to partner with Zoe and the entire Sequen team as they build the foundational infrastructure for every consumer company that wants to compete in the AI era. techcrunch.com/2026/03/18/seq…

Proud to share that @thresholdvc has invested in @adaptionlabs, which is announcing a $50M seed today. I couldn't be more excited to partner with @sarahookr and @sudip_r0y as they build (at lightning speed!) fundamentally different AI systems - models that are highly efficient and adapt in real time. Congrats to the entire Adaption Labs team on this milestone. Even more exciting things coming very soon - stay tuned! 🚀

We’re thrilled to have partnered with @SpellbookLegal, a company with a bold vision of reimagining how lawyers do their work by leveraging the power of AI. businesswire.com/news/home/2025…

We started @laborup_usa with a simple belief: America can’t rebuild its industrial base without rebuilding how we hire the people who power it. We raised $7.7M to build the defining AI solution that is Solving America's $1 Trillion Manufacturing Labor Crisis. I sat down with @dasha_shunina at @Forbes too share more.

I’ve noticed two common mistakes entrepreneurs make: one is thinking it’s all about them when it isn’t, and another is thinking it’s not about them when it actually is. Here’s why it’s so important for every entrepreneur to sort this out: threshold.vc/podcast/itrsqu…
