The posting, as Flagship Pioneering, Inc. wrote it

The Company

Iris Labs, Inc. is a privately held, early-stage company pioneering the use of artificial intelligence to transform how people navigate life’s challenges and wellbeing. We are creating a platform that empowers people to build a life they are proud of and fulfilled by. We bring together psychology, product, design, engineering, and machine learning to build digital experiences that are engaging, trustworthy, and genuinely helpful.

Iris Labs is backed by Flagship Pioneering, an innovation enterprise that conceives, creates, resources, and builds companies that invent breakthrough technologies that transform the world. Flagship has created over 100 groundbreaking companies since 2000, including Moderna.

The Role

Iris Labs seeks a Head of Product to lead the next stage of Iris Chat, our AI thought partner for psychological fitness. Through ongoing conversation, Iris helps people understand themselves, navigate relationships, and act on what matters to them. The successful candidate will own product strategy and execution, sharpen who we serve and why we matter, and turn promising user experiences into lasting value and a durable consumer business.

This is a hands-on executive role for someone with exceptional product judgment, strong consumer instincts, and the technical depth to lead across product, engineering, and AI research. You must be comfortable having engineering and AI research report to you, directly or through their leaders, with responsibility for hiring, development, priorities, and results. You should be as comfortable reviewing a difficult conversation or a retention cohort as setting strategy and building a team.

Working closely with company leadership, scientists, engineers, and researchers, you will shape both Iris Chat and the organization that builds it. Success will mean a focused roadmap, measurable improvements in activation and retention, a more useful experience across conversations, and a strong team that consistently turns research and user insight into reliable product improvements.

Key Responsibilities

• Define Iris Chat’s product vision, target users, most valuable use cases, differentiation, and roadmap. Translate long-term ambition into clear priorities, making disciplined decisions about what to build, sequence, and stop.
• Own the customer journey from onboarding and the first useful conversation through ongoing use and subscription. Set a high bar for conversational quality, memory, personalization, and thoughtful follow-up that helps users make progress over time.
• Drive measurable improvements in activation, cohort retention, conversion, and subscription value. Identify what makes users return, why they choose to pay, and what causes them to leave. Partner with growth on positioning, pricing, and acquisition economics, and with engineering on cost to serve.
• Lead product discovery through user interviews, appropriate conversation review, behavioral data, and support feedback. Turn in
