I joined PostHog when we were 11 people and had sold nothing. 5 years later, we’re now over 150 people and $$$ ARR. Here are 32 things I’ve learned – some unexpected, some kinda obvious.

A simple but powerful mental model for working with AI: treat it like an enthusiastic intern with no real-world experience. Paul Boag shares lessons learned from real client projects across user research, design, development, and content creation.

Summary:  In the managed-UX integration model, UXers report to UX leadership, stay connected to their peers, and work daily with product teams to drive outcomes.

Anthropic Claude is a primary competitor of OpenAI’s ChatGPT. Just like ChatGPT this is versatile tool that can be use used in many different purposes but there is an area where Claude shines and this area is coding. Claude is great at code-adjacent design tasks and can be used as a nice supporting tool for everyday product design activities.

Imagine a neighborhood with no sidewalks or ramps. Someone using a wheelchair or a parent pushing a stroller is immediately forced to drive or rely on others just to run simple errands.

The client came to us with an ambitious idea — to create a mental health support app that would help users cope with various psychological challenges and traumas. The core features included emotion tracking, meditation practices, and support through a built-in AI chat. The goal was not just to design a beautiful interface, but to build a thoughtful, user-friendly, and effective product that would stand out among competitors.

Commissioned by Network Rail to coincide with the railway’s 200th anniversary in 2025, the project aimed to create a standardised clock that could unify the passenger experience across the country while celebrating the rich heritage of British rail design. The result is a 1.8-metre physical and digital timepiece that fuses timeless symbolism with modern functionality, and reimagines one of the nation’s most recognisable icons in the process.

Shifting our focus from the designer or artist, and putting a spotlight on the printmakers and presses behind their projects, we spoke to some of the people crafting our tangible visual worlds about what the next generation of printmaking might look like… and if there is one.

Prompt treadmill is a situation that happens when you get stuck endlessly rewriting prompts to “make AI understand” your design intention, instead of actually moving forward. It’s one of the most annoying things that can happen when you work with AI, as you feel like you’re not moving forward, but instead burn rubber while remaining stuck in a rut.

Designers think the mockup is the product. Developers know the product lives in code. Until we kill the fantasy of the “handoff” and start building together from day one, we’re just shipping prettier silos with more emojis.
