Good thing this has been our entire investment thesis from day one @upwestvc
Sequoia saying what those in the Bay Area have known for the last 5 years. The only relevant cities for venture today are SF and TLV.

While the world debates what comes next, founders are out there building it. Spending time with the team at #BoltX was a powerful reminder of why we do what we do. #PhysicalAI @upwestvc

When everyone is chasing the same AI companies, who's exercising independent judgment? The checks and balances that should underpin venture investing seem to be disappearing. Good luck 🫰
I really don't get these tranched rounds. Think we'll look back in a couple of years, and see how this is a top of the market feature when investors just want to get into AI consensus, regardless of structure / price. This is still under discussed. Tier-1s are cleaning up on first tranche vals.

Zenity has been named a Market Shaper in the September 2026 Gartner® Emerging Market Quadrant for AI Application Security- Startup Vendors. Most AI application security tools stop at the mandatory baseline: scan the code, confirm a control exists, move on. AI applications introduce risks such as prompt injection, sensitive data leakage, and rogue agent action. Startups in AI application security offer solutions to secure and protect custom-built AI, AI agents, and models. Cybersecurity leaders can use these insights to evaluate startups in this new market evolution. This recognition comes shortly after Zenity was named the Company to Beat in AI Agent Governance. We believe these two reports cover the most critical dimensions of the emerging AI security market. 👉 zenity.io/resources/white-pa… #AISecurity #AgenticAI #AIAgentSecurity #Cybersecurity

Founders often misunderstand the CIO. They walk in selling product. The CIO is weighing consequence, outcome, security, adoption—and increasingly with AI: should we just build this ourselves? I sat with Yousuf Khan about the widening gap between Silicon Valley’s AI frontier and what enterprises are actually ready to adopt. 🎙️ Runtime Ep. 5 🔗 Link to full episode 👇

I've seen too many founders fail here and disregard signal from noise: "a real pre-emptive offer is a written term sheet. Full stop. Anything less, however enthusiastic, is simply an expression of interest." 👇
Over hundreds of venture rounds I’ve noticed they all fall into 1 of 3 paths 1. Investors throw cash at crazy growth (great!) 2. Founder runs a process that produces a term sheet (great!) 3. Hail mary stumble through cold pitches that gets lucky (avoid)

Founders get tired of selling. That doesn’t mean the sales motion is ready to hand off. Early on, founders have to do the selling and build the playbook. That’s how you learn and share what the next salesperson needs to win. But there's a catch. Founders have flexibility that the first salesperson doesn't. If a customer needs something, the founder can change the product. The salesperson has to win without that same authority. The handoff comes when there's enough of a playbook for someone else to take forward, improve, and build a system. Can someone else win with that playbook without depending on founder-only flexibility? That’s the real test. I joined @gilbenartzy on UpWest’s Runtime to talk about founder led sales, starting Stampli with my brother, Ofer, and the lessons I learned along the way. Thanks to Gil and the @upwestvc team for putting this session together.

🎙️From our second episode #Runtime a new podcast by @upwestvc. "Before there is product-market fit, there is founder conviction". @gilbenartzy sits down w/ @Lavi_kw Founder & CEO of #Canopy to talk about his contrarian early beliefs in remote patient monitoring in oncology. 👇

When starting #Canopy almost everyone told him the same thing: Cancer patients are too sick to engage. Oncologists won't change their workflows. Lavi believed they were all wrong. He built anyway. Today, Canopy is the leader in enterprise AI for oncology. 👇

Zenity, an Israel-based cybersecurity startup, has raised $125 million as part of a Series C funding round, in a bet that AI risks don’t come from powerful models, but instead from what happens when AI agents are set loose to act on their own. bit.ly/4fQyCk2
