Happy Tuesday Brex Community,

After 125 consecutive weeks (!!) of writing this newsletter into existence, I’m handing over the pen to Shai Goldman, who will continue leading what’s become one of the most influential founder ecosystems.

Today, the newsletter is read widely by founders and operators at OpenAI, Anthropic, Coinbase, NVIDIA, Clay, Perplexity, Vercel and by investors at a16z, YC, Tiger, Sequoia, Thrive, KP, Index, Pear, Insight, 8VC, Menlo and many more shaping the future of venture and technology. Together, we’ve highlighted breakout startups before they broke out, surfaced VCs with the highest founder NPS scores, built the Brex events calendar from a few dinners to a national movement and turned consistency into culture.

This is the moment where the pen leaves my hand. But the writing doesn’t stop. I’ll keep sharing what I see next: the deals, the investors, the builders, and the stories shaping the next wave. If you’ve enjoyed reading each week, I’d love to stay in touch. Follow me, message me, and let’s keep the exchange alive.

Joseph Shusterman is the Founder of Safsira

Safsira.com bridges the gap between digital engagement and physical experience. Its unified API and embeddable UI make it easy for any software platform—whether in gifting, fundraising, gaming, or HR—to seamlessly offer branded merchandise without ever touching inventory or supply-chain complexity. Safsira integrates directly with trusted global decorators and suppliers, handling everything from live pricing and product data to print-on-demand fulfillment. The result: companies can launch embedded merch experiences that feel native to their product, deepen customer connection, and unlock new revenue streams.

Imagine a CRM that ships a personalized co-branded gift as soon as a deal closes, a gaming platform that unlocks limited-edition merch for in-game achievements, or an event app that offers exclusive swag the moment someone buys a ticket. A fundraising platform can thank donors instantly. With Safsira, the path from digital engagement to real-world experience becomes a single API call.

Ambassador POV: Physical brand experiences have been slow to catch up with the digital economy. Safsira changes that by giving developers the building blocks to make swag as integrated as payments (Stripe) or messaging (Twilio). Already powering applications that let users gift, donate, and reward through branded merch, Safsira is becoming the connective tissue between the digital and physical worlds.
