Everyone is obsessing over the SpaceX IPO valuation, but while the headlines scream about billions, we’re looking at the actual rocket motors.

In this episode, Sascha Deri, CEO and Founder of bluShift Aerospace, joins us to break down the "SpaceX effect" on the industry (and explaining exactly why we refuse to play the "mini-SpaceX" game!). We’re cutting through the buzzword-heavy noise to talk about where the real value is hiding: solving the brutal, unglamorous supply chain issues that most people are ignoring.

We’re also opening up about why we’re building the future of propulsion from an RV in Maine, not a glass office in the Valley. If you want a take on aerospace that values real hardware over hype, you’re in the right place!

Ever wonder what it’s actually like to test a rocket engine? It’s not always the high-gloss, Hollywood-style launch you see on TV. In this episode, Sascha Deri, founder and CEO of bluShift Aerospace, joins us for a raw, unfiltered look at the reality of rocket development.

Join us as we pull back the curtain on the upcoming July 16 hot fire test of the MAREVL Engine! 

Sascha talks about the "60-second pucker moment", that high-stakes window where he forgets to breathe and puts everything on the line. But this isn't just about whether the engine fires or not; it’s about the "farmer wisdom" approach to aerospace: engineering for maximum performance, stability, and, most importantly, cost-effectiveness.

If you want the real story (the good, the bad, and the ugly!) this is it. 

Join us as we discuss why we aren't chasing "West Coast flash" and what it takes to build a rocket company that actually makes sense!

Want the insider truth about rocket science!? 

Forget the spectacle. On this episode of Throttle Up, bluShift Aerospace engineers Luke Saindon and Gerard Desjardins join Justin Starbird to pull back the curtain on the unseen world of getting a rocket off the ground. 

We dive into high-stakes FAA licensing, the terrifying reality of failure probability, and the logistical nightmare of turning a test engine into a flight-ready system. 

Hear how a successful engine test can still mean a 50/50 chance at launch, and what happens when a rogue fire extinguisher valve sabotages the entire day. 

Stop watching the countdown, tune in now for the unfiltered engineering truth!

Forget the Hollywood countdowns, the real drama in rocket science happens on the test stand! 

On this episode of Throttle Up, we go inside bluShift Aerospace with the two people making the engine work: Lead Mechanical Engineer Luke Saindon and Lead Propulsion Test Engineer Gerard Desjardins.

They reveal the constant, high-stakes battle between complex computer modeling (optimizing weight vs. power) and the physical grind of the test lab. From mixing bio-fuel to surviving engine test day, this is the honest, raw story of building a hybrid rocket motor from the ground up.

Tune in for the unfiltered truth about the compromises, the 99 problems (but the fuel ain’t one), and the intense focus required to launch a new era of spaceflight!

On this episode of Throttle Up, host Justin Starbird sits down with Sascha Deri, Founder and CEO of bluShift Aerospace, for a deep conversation about what previous investment capital has actually unlocked for the company and why the next phase of growth matters.

Sascha walks through bluShift’s evolution from an early prototype developed under a NASA SBIR contract into a propulsion company that has now built large-scale engine testing infrastructure, secured federal contracts, developed engines capable of producing up to 20,000 pounds of thrust, and positioned itself within the rapidly growing hypersonics and booster markets. The discussion gives listeners a rare look into the realities of hard-tech development, including the engineering challenges, infrastructure requirements, capital efficiency, and strategic decisions required to advance a propulsion platform in one of the most demanding industries in the world.

The episode also explores how bluShift has leveraged a combination of non-dilutive government funding, private investment, and community support to move significantly faster and more efficiently than many competitors in the sector. Sascha shares why the company ultimately pivoted from focusing primarily on orbital launch toward solving larger propulsion and booster market opportunities, and how those decisions have shaped bluShift’s commercialization roadmap moving forward.

For investors evaluating aerospace opportunities, this conversation provides critical context around bluShift’s technical progress, testing milestones, capital discipline, infrastructure development, market positioning, and long-term growth strategy. It also offers insight into the culture, transparency, and execution mindset driving the team as they prepare for the next stage of development and future flight milestones.

If you want to understand what it actually takes to build a propulsion company capable of reaching commercialization in today’s aerospace market, this is an episode you do not want to miss.

Welcome back to Throttle Up! We’re diving deep into the tech that’s redefining rocket propulsion. CEO Sascha Deri welcomes CTO David Hayrikyan, the engineering force on site, to discuss exactly what bluShift has built and why it stands apart from today's launch systems.

In this episode, we talk grit, engineering, and the real-world simplicity that is cutting costs and complexity:

• What is a Hybrid Rocket Engine? David breaks down how their system uses solid fuel and liquid oxidizer to deliver all the performance needed for suborbital and hypersonic testing, without the cryogenics or massive price tag of the "Ferrari of rockets".

• Bio-Derived Fuel: Is it safe? Sascha, the guy who ate the fuel on CNN, explains the huge practical benefits: ease of availability, simple logistics, and zero explosive danger in manufacturing compared to traditional solid rocket motors. The fuel is more energy-dense than liquid fuel and makes manufacturing far simpler.

• The Skunkworks Story: David shares his passion for working until 2 a.m. in the early days and how Sascha’s relentless optimism helped a small team achieve what usually takes tens of millions of dollars.

• The Next Big Launch: What are the final technical hurdles before bluShift sells its first engine to a hypersonic customer? Sascha shares his excitement for the "awesome moment" when the full stack fires vertically.

Ready to hear how real rocket scientists are shaking up the space industry!?

In the inaugural episode of Throttle Up, host Justin Starbird sits down with bluShift Aerospace CEO Sascha Deri to launch into the real work behind getting a rocket from concept to launch. 

Sascha breaks down how bluShift's proprietary, bio-derived fuel and hybrid rocket technology are fundamentally changing the game. They're not just reducing costs; they're dropping them to 1/100th of what traditional solid rocket motors cost for production and 1/4 of the price for the final engine!

Learn how Sascha’s background as a serial entrepreneur informed the company's culture, a focus on spending money wisely, and hiring "gritty" people who can both design and build. 

Plus, get an exclusive look at the massive market opportunity bluShift is seizing, including solving a national security shortfall and delivering the lowest-cost hypersonic testing capability in the U.S.!

Welcome to the Throttle Up Podcast, a behind-the-scenes look at what it takes to build and launch a new class of rocket propulsion.

Hosted by Sascha Deri, Founder and CEO of bluShift Aerospace, and storyteller & entrepreneur Justin Starbird.

This podcast follows the real work behind the mission.

From early design and propulsion development to testing, capital, partnerships, and the path to launch, each episode brings you inside the process as it unfolds.

bluShift Aerospace is advancing a new approach to propulsion, built around performance, sustainability, and a long-term view of how to disrupt the market for solid rocket motors used in defense and commercial launch.

The journey requires discipline, iteration, and a clear focus on execution. Progress is built step by step, through decisions, setbacks, and milestones that move the system forward.

Each conversation is designed to share that progress in a way that is grounded, transparent, and useful to the people following along.

For engineers, investors, partners, and anyone interested in how complex systems are built and brought to life, the Throttle Up Podcast offers a clear view into the work behind getting to launch.
