Subject: $2.8K MRR │ Looking for a technical partner
Hi all,
I'm building Northstone, an AI-enabled accounting service for Danish small businesses. It's live, paying, and profitable: ~$2.8K MRR today and growing. I'm looking for a technical co-founder to build the product side with me.
The short version
Bookkeeping in Denmark is expensive, slow, and dependent on whichever person happens to do your books. Northstone replaces that with a system. AI runs intake, task generation, QA and reporting; a senior bookkeeper reviews, decides and signs off. The quality lives in the system, not in any individual, so we can add capacity cheaply without quality dropping.
Clients pay one all-inclusive monthly subscription that replaces their bookkeeper, payroll bureau and annual-report accountant combined. Cheaper on total cost than any traditional firm, above average on quality.
Why this is a real business, not a someday idea
About me
Former accountant and CFO, so I know this industry from the inside. I own sales, ops, and all the accounting logic. Before this I led a startup from $1M to $25M in revenue, so I've done the 0-to-scale part before and know what it takes.
Who I'm looking for
A developer who's genuinely comfortable building with AI, because the AI is the product here, not a bolt-on feature. You'd own engineering end to end: the monthly close engine, the internal tooling, and eventually the ERP. You don't need any accounting knowledge, that's my half. Bonus if you've shipped something solo and like owning a codebase.
The deal
Meaningful equity in the company, plus a small cash component funded from current profit and soft funding. Real ownership, and enough cash that this isn't pure sweat equity. We'll shape the exact split around what you need.
If a profitable base, a clear roadmap, and an AI-native product sound like your kind of thing, reply here or DM me. Happy to walk you through the full strategy deck.
Interesting approach. Building the quality into the system instead of relying on individual operators is exactly where I think AI-enabled service businesses have an advantage.
We've been helping startups and growing companies build AI-powered SaaS platforms, workflow automation, ERP solutions, and custom business applications. Your roadmap from bookkeeping to a full ERP platform sounds like a strong long-term opportunity.
If you're open to exploring a technical development partner alongside your co-founder search, we'd be happy to connect and share how we've helped similar businesses scale their products.

Hey Bernard,
I've been building AI-heavy B2B SaaS products for 7+ years — legaltech, fintech, document-heavy systems. The last few years specifically working with early-stage founders as their first technical person across India, US, and Dubai — taking full ownership, making product and architecture decisions, shipping from zero.
The kind of work you're describing — AI running intake, task generation, QA, then a human signs off — I've built exactly this pattern. Document processing pipelines, verification systems, accuracy going from broken to production-grade. That's the core of what your close engine needs.
I work retainer + small equity, which sounds like what you have in mind. Outcomes-based, phase by phase, you always know what's getting built.
I don't know Danish accounting — don't need to, that's your half. My job is turning your logic into something that scales.

Happy to jump on a call.
Interesting post.
The thing I'd be careful with is that finding a technical partner and convincing the right technical partner are not necessarily the same problem.
You clearly have revenue, industry knowledge, and a roadmap. The harder question may be which part of the opportunity the strongest candidates actually anchor on when deciding whether to join.
I would not make that call casually in a thread because it changes how the entire opportunity is presented.
Curious what kind of responses you're getting so far.
