Mosaic is a partner-only firm. The sourcing, pipeline management, deck analysis, and meeting prep that would traditionally fall to a junior investment team is now handled by partners working alongside purpose-built data infrastructure and AI-native workflows, because two years ago we made the bet that intelligent machines could do it better.

OpenAI has some big questions. It doesn’t have unique tech. It has a big user base, but with limited engagement and stickiness and no network effect. The incumbents have matched the tech and are leveraging their product and distribution. And a lot of the value and leverage will come from new experiences that haven’t been invented yet, and it can’t invent all of those itself. What’s the plan?

Parloa has announced a landmark Series D fundraise, led by General Catalyst at a $3B valuation – a huge milestone on the path to building a legendary company.

How far do LLMs give us a step change in how good a search and recommendation system can be? Do they let you build one without needing a vast user base of your own?

Twice a year, I produce a big presentation exploring macro and strategic trends in the tech industry. New in November 2025: ‘AI eats the world’.

With every platform shift, we want to measure the growth but we’re confused about what to measure. That’s partly a problem of data and definitions, but it’s really a question about what this is going to be.

Generative AI chatbots might be a life-changing transformation in the nature of computing, that can replace all software, but so far, most of its users only pick it up every week or two, and far fewer have made it part of their lives. Is that a time problem or a product problem?

Why you need to rethink your pricing for the agentic age

We're excited to announce that Parloa has raised a $120M Series C, at a $1B valuation.

Software ate the world. Uber and Airbnb didn’t sell software - they disrupted and redefined markets. But what kind of disruption are we talking about ?

It matters that Apple’s new Siri will be late, and it matters more that Apple didn’t realise. Is it more than that?

Every week there’s a better AI model that gives better answers. But a lot of questions don’t have better answers, only ‘right’ answers, and these models can’t do that. So what does ‘better’ mean, how do we manage these things, and should we change what we expect from computers?

OpenAI’s Deep Research is built for me, and I can’t use it. It’s another amazing demo, until it breaks. But it breaks in really interesting ways.

We’re excited to announce that we have promoted Chandar Lal to join our partnership.

Will Apple build a search engine? Will ChatGPT change search? Does it matter?

Hundreds of millions of people have tried ChatGPT, but most of them haven’t been back. Every big company has done a pilot, but far fewer are in deployment. Some of this is just a matter of time. But LLMs might also be a trap: they look like products and they look magic, but they aren’t. Maybe we have to go through the slow, boring hunt for product-market fit after all.

Meta has spent at least $50bn on VR and AR so far, but we’re still in the VR winter: the devices aren’t good enough or cheap enough and the user base is flat. But no matter how good the devices get, how many people will care?
