David Friedberg takes America's 250th anniversary as a starting point to ask where does the country actually stand? And how do the bottom 50% get left behind?

CJ Desai, President & CEO of MongoDB, joins Sourcery at the RAISE Summit in Paris. We cover why data is the downstream winner of the AI cycle, how hyperscaler capacity limits are pushing workloads back on-prem, the return of data sovereignty, & what a bank's real agentic architecture actually looks like.

Day 1 of RAISE Summit in Paris, the most high-profile AI summit in Europe. We pulled 10 of the sharpest founders, operators, and investors aside for their hottest takes on the debates defining AI right now.Open source vs closed models dominated the room, alongside agents rewriting how work gets done, the death of the keyboard and mouse, the economics of inference, and physical AI moving from data centers into cars, devices, and even orbit. Real numbers, real disagreements, and a few pieces of breaking news, straight from the people building it."The keyboard and mouse are slowly dying." - Max C

Day 2 of RAISE Summit in Paris, the biggest AI summit in Europe. 12 founders, operators, and investors give us their hottest takes on the debates splitting the room right now: is token maxing genius or a waste, is open source dying or about to take over, and are we in a bubble.The disagreements were the best part.

Qasar Younis (Applied Intuition) on the opulence phase of the cycle and the pullback he sees coming. Apoorv Agrawal (Altimeter) on the four

Eric Romo, President & COO of Impulse Space, joins Sourcery on the company's manufacturing floor in Redondo Beach to break down the freshly closed $500M Series D co-led by 137 Ventures and BANNER VC that pushes Impulse past $1 billion raised. We get into what the capital actually unlocks (hiring and production, not flashy CapEx), why "space tug" doesn’t cut it for Mira, and how a single successful flight spurred demand from across the industry. Eric explains Impulse's three products — Mira, Helios, Caravan — and makes the case for staged access to GEO against traditional options. He also gets

Tom Mueller, Founder, CEO and CTO of Impulse Space, (aka Employee #1 at SpaceX) gives Sourcery a walkthrough of the company's Redondo Beach factory, from the avionics clean room to a live rocket engine firing in the vacuum chamber.

Brian Singerman spent 17 years at Founders Fund, where he helped drive large concentrated investments into companies like SpaceX, Palantir, Airbnb, Stripe, Stemcentrx, Anduril, and Affirm. He recently left to co-found GPx, a new fund backing emerging managers. In this episode we break down the philosophy behind Founders Fund's concentration strategy, how a lifetime of competitive strategy gaming shapes the way he reads founders, and why he is now applying the same framework to GPs instead of companies. "When I did get to meet Elon and learn more about SpaceX, it was extremely clear that there
