The real IP in agentic accounting

A couple of weeks ago Basis, a US-based tech startup building AI agents for accounting firms, announced its $100m funding round. A serious amount of money. This is both a strong signal of the opportunity for Agentic Accounting and a clear indication of the economic benefit flowing up to the model builders (eg. Anthropic, OpenAI). Howev...

Just like software, agentic AI will fragment accounting not destroy it

Last week I was given the opportunity to sit down with a true accounting tech early-adopter, Dave Sellick, who runs Sidgrove, a UK-based boutique CFO/accountancy firm, and chat about agentic AI. Dave was sceptical. Well, maybe he still is... but not hostile or dismissive of the technology. Really just sceptical. As for me, I love this ...

Accounting service as a software follow up

In the previous post I wrote: “And also, the incentive problem: a vendor sitting on top of encoded expertise of hundreds of accounting firms has something way more valuable than the SaaS subscription revenue itself. They have the aggregate knowledge to do the work itself and cut off the middleman.” And just this morning, something abou...

18 months is a long time...

As this attempt at reviving a blog progresses, I went to log in into my old Medium account and bumped into a queue of very old drafts: The draft had a couple of interesting notes: And also: It'll be awesome indeed!

Product roles in the age of agentic AI development

I was watching Office Space the other night. There's this scene where the Bobs are interviewing Tom, the product manager. They're trying to understand what he does there. Tom's (frustrated) answer is that he takes the specs from the customers and brings them to the engineers. That film is from the late 90s and it captures some of what ...

Building a complete SaaS product with only Claude Code

“A solo developer product-minded founder with AI co-authorship, built a production-grade, multi-tenant SaaS with billing, authorisation, media management, email, analytics, documentation, and marketing pages in under two months. The git history reads like a startup sprint diary -- ambitious, relentless, occasionally messy, and ultimate...

I wonder if...

Right now I’m looking at Claude Code running in the console. I’m watching it churn through stuff. For a few different reasons, this week has reminded me of a couple of old projects that were pretty intense and kind of fun in hindsight. The first one was about 25 years ago. We were building a CRM for the Nokia 9210. We were doing it in ...

Voice to post

I came across Granola and it's been absolutely fantastic for handling my meeting notes and organising them into neat, structured content. It excels at converting scattered thoughts into organised notes, capturing action items, and even helping with follow-up emails. But here's where it gets really interesting (for me)... I really don't...

Hey there

I guess it's been a while since I blogged anything, and even more of a while since actively being on the ball. Nearly 17 years... The hiatus is nearly old enough to go to university. There's so much to unpack (2 venture backed startups, being part of a few interesting teams in the in-betweens), and having dug so far into the past I cou...
