Just Now Possible

Teresa Torres

How AI products come to life—straight from the builders themselves. In each episode, we dive deep into how teams spotted a customer problem, experimented with AI, prototyped solutions, and shipped real features. We dig into everything from workflows and agents to RAG and evaluation strategies, and explore how their products keep evolving. If you’re building with AI, these are the stories for you.

    Creating Aha! Builder: Concept to Code, No Engineers Required

    What does it take to build an AI app builder specifically for product managers—not engineers—inside an already crowded market? In this episode of Just Now Possible, Teresa Torres talks with Brian De Haaff (CEO and Co-Founder), Chris Waters (CTO and Co-Founder), and Sarah Moisan-Thomas (Senior Product Manager) about Aha! Builder, Aha!'s AI-powered app builder built for product managers. Aha! is a fully bootstrapped, profitable, remote-first company that has served product teams for over 13 years without a single salesperson. They walk through Aha!'s five-step product discovery framework—spark, paper prototypes, proof of concept, early access, and general availability—that led them to Builder. They share why their first version, built on containerized Ruby on Rails infrastructure, proved too wasteful to scale, and how they rebuilt it on a single-instance, multi-tenant architecture using V8 isolates. Along the way, they explain their approach to deterministic guardrails for things like authentication, SSO, and databases, and how a multi-phase, multi-agent pipeline generates a design system, a prototype, and a working application in minutes. You'll hear how they think about the line between what AI should build and what should stay deterministic, how they handle enterprise concerns like SSO and PII, and why they believe knowing what to build—not how to build it—is where product managers will increasingly add value.

    Building AI for Women's Health: How Hertility Combined Bayesian Diagnosis and Scan Automation

    How do you build trustworthy AI diagnostic tools in one of medicine's most historically under-researched areas? In this episode of Just Now Possible, Teresa Torres talks with Tulsi Patel (Director of Product and Technology), Lorna Brightmore (Head of Data and AI), and Jack Pickard (Head of Engineering) at Hertility, a UK and Ireland-based women's health tech company. Hertility combines an in-depth online health assessment with at-home hormone testing and clinician-reviewed reports to help diagnose conditions spanning menstruation to menopause. Built on seven years of data linking symptoms, blood results, and pelvic ultrasound scans for over a million women, the team walks through two AI products in development: Gyn.AI, a Bayesian network that gives clinicians probability-based diagnoses instead of binary calls, and a scan automation pipeline that classifies ultrasound images, measures follicle counts and ovarian volume, and drafts clinical letters using an agentic loop that checks its own output against patient data before a human ever reviews it. You'll hear how the team guards against automation bias, builds clinician trust through transparency, minimizes PII before it ever reaches a model, and treats healthcare regulation as a design constraint from day one rather than a last-minute scramble. It's a detailed look at what it takes to bring AI into one of the most sensitive, tightly regulated corners of healthcare.
