This episode of This Week in Startups features a mix of mentorship calls with ambitious young callers and an interview with Sean Ready, the co-founder and CEO of Aristotle. The host spends the first half of the show advising students on how to approach their careers, emphasizing the power of reading biographies, mastering AI tools first, and building holistic skills instead of narrowing oneself too early. Later, the conversation shifts to education and AI with the founder of Aristotle, who explains why traditional large language models are actually getting worse at teaching due to verbosity and lack of pedagogical focus, and how voice-based multimodal AI tutors can deliver personalized learning akin to human tutoring.
The discussion provides deep insights into the current state of educational technology and venture building. The host and guest unpack the mechanics of effective pedagogy, contrasting the automated generation of raw answers with the nuanced, step-by-step guidance required for genuine cognitive struggle and student mastery. Listeners get a pragmatic look at how verticalized AI architectures and proprietary data collection are shaping the next generation of software products, moving beyond simple API wrappers into specialized domains.
Hosts introduce the episode, announce sponsors, and set the tone for the discussion.
Jason answers a caller’s questions about living in New York, dating, and navigating finance studies while emphasizing AI-first learning and reading biographies.
Jason discusses how a caller might allocate a hypothetical $500K, covering personal skill investment, starting a company, or investing in markets, and stresses the importance of reading biographies for growth.
Jason responds to a caller questioning the motives behind AI caution, exploring industry, regulatory, and philosophical factors influencing AI’s perceived risks.
Jason discusses how AI can address American priorities like education, healthcare, and home ownership, and considers the debate over AI use in schools.
Sean explains that while AI excels at complex reasoning, it struggles with pedagogical tasks, prompting the creation of Aristotle.
The team showcases a live AP Calculus BC session, highlighting the system’s human‑tutor‑like interaction.
Sean outlines Aristotle’s tutoring‑service model, session packs, and subscription tiers aimed at high‑school students.
Discussion of the company’s custom LLM, benchmarks, and the challenges of creating a model tailored for teaching.
Sean addresses the creation of a unique tutoring dataset, privacy concerns, and potential secondary revenue streams.
Read Biographies Instead of Seeking Coffee Chatsstrategy
The host advises young professionals and founders to skip trying to network for coffee and instead read ten biographies a year to understand entire industries.
Why Big Tech Employees Do Not Steal Ideasinsight
The host explains that employees at large companies typically work limited hours and lack the drive to steal startup ideas, unlike ambitious immigrant founders.
Coffee and Croissant Customer Discoverystrategy
An aggressive customer discovery tactic is shared where founders buy coffee and pastries for strangers at cafes to test consumer apps and gather feedback.
Using Indirect Market Research Tacticsstrategy
The host discusses clever, non-illegal corporate intelligence techniques such as setting up research systems to harvest genuine market feedback from professionals.
AI Labs and Religious Scholars Meetingstory
The host and guest discuss recent news of AI safety teams consulting religious scholars about whether models like Claude have souls.
Why General AI Models Fail at Teachinginsight
The guest argues that general LLMs are actually getting worse at teaching because they generate overly verbose, fast answers rather than fostering student struggle.
The Bloom's Two Sigma Problemdata
The guest explains Benjamin Bloom's famous study showing that one-on-one tutoring yields a two-sigma improvement in student learning outcomes.
“Read all the biographies, 10 a year minimum. And you can listen to them too.”
“You just read the biographies, you'll be fine.”
“If you want to understand what building on a true AI native platform looks like, go to do.co/twist.”
“One-on-one tutoring delivers two sigma improvement in learning outcomes for students.”
“We are building our own harness. Two, we are building our own internal set of benchmarks and evals, which are the first of its kind, defining what is good one-on-one human-to-AI instruction.”
“We want them to feel like they are talking to a human tutor. That tutor derives the session, sets the agenda, pulls questions out of the student, diagnoses their misunderstanding and so on, and meets them where they are.”
“The way that I describe this is it's, we're trying to build an experience that's just like sitting next to a human tutor.”

Shan Reddy of Aristotle joins Jason to demo a voice-first tutor built to run a session the way a $200-an-hour human tutor would. We also dive into why frontier models are trained to hand you answers rather than build real understanding. PLUS, in Ask Jason, an incoming Fordham student (Jason’s alma mater!) wants to prepare for a career in finance. Plus, David from NYU calls back and wants to discuss what everyone would do with $500K in free money. Then, why does Jason think the Doomerism is coming from inside the AI labs?
