The only sustainable innovations that actually scale are the ones customers never have to think about. Josh Dorfman has spent two decades building them. Josh Dorfman is the co-founder of Planted (plantdmaterials.com), a materials startup building structural panels from fast-growing grass as a direct replacement for wood-derived products in U.S. home construction. He came up through consumer sustainability media (books, Sirius radio, TV) under the Lazy Environmentalist brand before pivoting to B2B climate technology. In this conversation, Josh and Alex explore the mechanics of low-friction sustainability across building materials, aviation, carbon credits, and the unexpected efficiency gains hiding in the GLP-1 drug story.
What You'll Learn The Drop-In Rule: Sustainable materials only reach scale when they integrate into existing workflows without asking the customer to change anything. B2B green sales: Even the most environmentally committed executive cannot justify a purchase on environmental grounds alone. The product has to win on performance and price first. The Trove playbook: Climate companies that succeed eventually stop leading with climate, treating sustainability as a downstream brand benefit rather than the sales pitch. Carbon credits: Voluntary offset schemes largely transfer the cost of an airline's impact onto consumers while delivering minimal real-world emissions reduction. GLP-1 and aviation: Jefferies estimates adoption of weight-loss drugs like Ozempic could save U.S. airlines around $580M annually in fuel costs, about 1.5% of fuel spend. Jefferies separately modelled a 2% weight reduction translating to roughly 4% EPS uplift. The point: the most significant efficiency wins are often not engineering solutions. Battery cost curves: Declining battery costs are already reshaping U.S. power grid additions (51% solar, 28% battery storage projected for the next 12 months) and will accelerate electric aviation faster than most forecasts assume. Grass over trees: Planted's core material grows 10x faster than timber and can be harvested annually, enabling carbon sequestration at a scale that tree-planting programs cannot match. Storytelling as company-building: In a venture-backed startup, the founder is simultaneously selling the company and the product. The skill set required is identical.

An AI asked to protect every passenger connection gave a flawless answer: cancel the flights. Kevin Hightower is Chief Innovation Officer at Cirium, where he leads Propulsion Labs, the company’s innovation group. He and host Alex Brooker, former colleagues at Cirium, discuss Kevin’s path from oceanic air traffic control at Lockheed Martin to Google’s drone delivery program, how AI is changing product development and decision making in aviation, Cirium’s aviation knowledge graph, and the data interoperability problems holding the industry back. What You’ll Learn Automating the routine: Lockheed’s oceanic ATC system let controllers comfortably manage 30 aircraft instead of a busy 7 to 15 by automating conformance checks and altitude probes. The three hour rule: No decision, from buying a car to buying a company, should need more than three hours of actual thought, with data gathering kept separate from thinking. Disposable prototypes: When AI cuts build time from months to days, the discipline shifts to throwing work away instead of defending ideas because of the effort already spent. AI as an accelerant for learning: Early career engineers who use AI to compress years of learning will outpace those who use it only to do an old job faster. Decisions, not dashboards: Most aviation decisions run roughly eight steps, and AI can now carry four or five of them before a human makes the call. The aviation knowledge graph: Aviation data starts with an aircraft and links orders, lessors, schedules, and tail swaps, so connecting it unlocks analysis no single dataset can. Efficiency before safety: AI will speed up flow management and sequencing well before it touches the safety critical systems that keep aircraft separated. The interoperability gap: Multi year, multi million dollar data lake programs rarely deliver usable value, and the real problem is combining data across boundaries while keeping control of it.

AI made writing code nearly free, which only matters if code was ever most of the job. In this compilation episode, host Alex Brooker pulls together clips from seven past guests across travel software, airspace infrastructure, airline operations, corporate travel, content, and airline ancillaries who each arrived at the same idea independently. Alex Ragin of Zoftify puts a number on it: code is about 20% of a software product, and the other 80% is domain knowledge, process, and judgment. The episode follows that 80% through edge cases, daily operational disruption, fare construction expertise, and the question of what a product team's job becomes when execution costs almost nothing. What You'll Learn The 20/80 split: Code is roughly 20% of a complex travel system, and the remaining 80% is knowledge of how the business actually works. Vibe coding limits: A simple invoicing app can be vibe coded, but a CRM, ERP, or GDS cannot, because the hard part is specifying behavior rather than writing it. Edge case cost: One modest custom fields feature at Zoftify took about five days of internal and client discussion before it was ready to build. Failure at the seams: Complex systems break at their interfaces and edge cases, not on the happy paths that teams test and load test. No standard day: In airline operations, disruption from weather, aircraft swaps, or system faults is the normal state rather than the exception. Expertise outside the code: International fare specialists routinely beat GDS pricing engines by thousands of dollars by knowing where to break a fare. Where value moves: As development costs approach zero, advantage shifts to network effects, knowledge of customer pain, and position in the customer journey. The new job: When execution is cheap, deciding what to build and why becomes the core work for every team, not just well funded ones.
Two euros can decide who wins a metasearch sale. Inside most airlines, moving them is still revenue management's call, and it is rarely fast.
Everyone is racing to build the AI agent that books your trip, and nobody is building the thing that makes it safe to use one.
A guy who used to hand carry passports to airport cargo terminals just built the database he couldn't afford in 2018 for a fraction of the cost, and every application still passes through a human before it goes anywhere. Rob Lee is CEO and co-founder of Swift Passport and Visa Services, a company he started in 2008 helping private aviation clients navigate passport and visa logistics. In this conversation, Rob traces the industry from same day passport courier runs through the shift to eVisas and ETAs, and explains why his team uses AI heavily to build internal tooling while keeping customer data out of public AI tools and a human check on every application.
