$2.8K MRR│Looking for a technical partner

"Bernard, I saw your post on Northstone. You are looking for a technical co-founder, but maybe you just need the right technical foundation. I have a production-ready AI crypto accounting engine. Instead of hiring a co-founder and splitting equity, you can acquire this engine, plug it into your system, and start offering crypto services to your Danish clients immediately. Let's discuss."

Ciao Bernard,

Quello che mi interessa di piu' non e' la parte contabile in se', ma la traiettoria che descrivi: da servizio di contabilita' con IA a piattaforma ERP proprietaria. E' un caso raro in cui lo strumento interno diventa il prodotto vero e proprio - e per arrivarci serve qualcuno che sappia costruire agenti che spediscono in autonomia, non solo scrivere codice.

Lavoro ogni giorno con Claude Code per costruire sistemi agentici che pianificano ed eseguono processi reali end-to-end. Se ti interessa vedere come mi muovo prima di parlare di equity o ruoli, dimmi un pezzo concreto della pipeline attuale (acquisizione dati, chiusura mensile, o altro) e ti preparo un piccolo proof-of-concept.

Hi Bernard,

I came across Northstone and was immediately interested because this is not just an idea-stage co-founder opportunity—you already have a live, profitable product, paying Danish customers and clear founder-market fit in accounting and finance.

I’m Sabbir Hossain, a software engineer and technical founder with experience building AI-powered SaaS, regulated data platforms, workflow automation systems and blockchain infrastructure.

My relevant work includes:
• Patient Bio— a healthcare data and workflow platform focused on patient-owned records, consent management, secure data sharing, audit trails and provider-facing dashboards
• Swanex — an enterprise Web3 platform with role-based administration, KYC workflows, payments, private blockchain infrastructure and production-grade security
• AI and SaaS systems involving RAG, workflow automation, multi-tenant architecture, approval processes, analytics dashboards and API integrations

Northstone strongly matches the type of company I want to help build. I can take technical ownership of:
• AI-powered bookkeeping and transaction-classification workflows
• Document ingestion, extraction and validation pipelines
• Human-review and approval systems
• Monthly-close automation
• Explainable accounting decisions and audit trails
• Internal operations dashboards
• Secure, scalable multi-tenant SaaS architecture
• The longer-term evolution from accounting automation into a full ERP platform

What makes this especially compelling is the founder-role clarity. You bring accounting expertise, customer understanding, operations and sales, while I can focus on product architecture, engineering execution and building the technical moat.

I would be interested in reviewing the product demo, current architecture, customer and MRR history, roadmap, proposed equity and vesting structure, cash component and expectations for the technical co-founder.

Northstone appears to have the foundations of a serious B2B SaaS company, and I would be glad to explore whether we are the right founder match.

Best,
Sabbir Hossain
Software Engineer | AI, SaaS, Healthcare and Web3 Builder

Hi Bernard, I am interested in learning more. Where can I contact you?

Congrats on getting Northstone profitable before even bringing on a technical co-founder — that's a genuinely strong negotiating position, like someone said above.

One thing I'd want to know for sure before giving up equity: is a technical co-founder actually the constraint, or is it capacity/execution speed (which a fractional hire or the right tooling could solve without touching ownership)? Those are really different problems and they get solved really differently.

I've been building a process for exactly this kind of question — figuring out what's actually blocking a founder vs. what looks like the blocker. Happy to take a real look at Northstone and share what I find, free, no pitch. Let me know if that'd be useful.

[email protected]

Would love to connect on this! I'm a UCLA student studying CS, and have built a bunch of AI products including one I'm working on right now. send me an email on reyanshsankhyan@ucla . edu to reach out, I think we can find value in each other.

Hey — this really resonates with me. I'm a full-stack dev (TypeScript/Next.js, Node, Postgres) and I build AI-native: I run multi-agent Claude Code setups for real production work, not just chatbot demos.

Full honesty up front: I'm still finishing my apprenticeship in software development, so I'm early-career and can't go full-time right now — but I'm serious about building something real, and this is exactly the kind of project I'd want to grow into.

I'm not looking for a salary upfront. I'd rather earn my place through equity as the thing grows. Happy to start with a small trial task or prove myself on something concrete first, so you can see how I actually work before committing to anything.

The close engine is what stands out to me. The hard part isn't calling an LLM — it's the audit trail, so a senior accountant can review, override, and sign off with confidence. Get provenance and human-in-the-loop right and the quality lives in the system, exactly like you said.

Would love to chat about the technical roadmap. Feel free to reply here and I'm happy to share my portfolio and contact details.

Hi Bernard,

Congratulations on getting Northstone to profitability. Getting to paying customers before raising capital says a lot about the business.

I run Kodawa Labs, where we partner with founders who have strong domain expertise but need additional execution capacity to move faster.

Beyond websites, we help with product design, frontend development, AI integrations, automation, proposal drafting, investor-ready landing pages, and technical delivery through our white-label engineering team.

I don't think we'd replace the technical co-founder you're looking for, but I do think there could be an opportunity to accelerate Northstone while you continue your search.

If you're open to it, I'd love to learn more about the product roadmap and see if there's a way we can help.

— Brian
Founder, Kodawa Labs

Hi Bernard — congrats on Northstone's traction. While you look for a technical co-founder, you don't have to wait to get the platform built: we deliver fixed-price (from $1,999-$4,999), 7-day builds with the AI features, admin tooling and payments you've described — live on your domain, no equity involved. Could be a fast way to prove the platform side while the co-founder search continues: grahaisystems.com/launch

Hi Bernard, congratulations on reaching $2.8K MRR! The fact that you're a former CFO who deeply understands the domain is a huge advantage. In my experience, the best software is built when the person defining the problem truly understands the operational reality.

I work as a Technical Product Manager and full-stack builder, and your philosophy that "the quality lives in the system, not the individual" really resonates with me.

Recently, I combined four years of clinical operations experience with AI-assisted development to architect and build a complete local-first EMR from scratch using React, Node.js, TypeScript, and PostgreSQL. The platform includes six core modules, five user roles, and a robust role-based access control system designed for real-world clinical workflows.

I also built HiringFlow, an AI-powered recruitment automation platform using n8n and the OpenAI API that automated manual screening workflows and significantly reduced the time spent reviewing candidates.

What excites me most is owning the entire product journey, from understanding messy operational problems to designing the architecture and shipping production-ready software. That's why your vision for Northstone immediately caught my attention.

I'd love to take a look at the strategy deck and chat about how I could contribute to building the next stage of Northstone. I'll send you a DM.

Very interesting opportunity. My background is in ERP systems, full-stack engineering, AI integration, and business automation, and I've spent years building systems where workflow automation and domain expertise intersect. Your thesis that the quality should live in the system rather than in individuals resonates strongly with me. The path from AI-enabled accounting operations to a proprietary ERP platform also makes strategic sense. I'd be interested in discussing the technical vision, AI architecture, and long-term product roadmap in more detail.

I'm a Senior Full Stack Engineer with 10 years of experience building SaaS products, AI applications, and backend systems. I recently started consulting and spend most of my time building products with TypeScript, React, Next.js, Node.js, and AI tools.

Hey, this looks like a solid product with real traction already congrats on getting to revenue stage.
I run a small engineering studio (Havixta) focused on building MVPs and SaaS systems using Python+ scalable backend architecture.
Your approach of system-driven quality instead of manual dependency is exactly the kind of architecture I’ve built before in similar automation-heavy systems.
I’d be interested in understanding the current architecture and where engineering bottlenecks are right now especially around the monthly close engine and internal tooling.
Happy to jump on a quick call if you're open to it.

Great, I am interested too.

Hi Bernard,

This is one of the few co-founder posts that actually caught my attention. A profitable business with a clear roadmap is much more interesting than another idea-stage startup.

I'm a senior full-stack and AI engineer with experience building SaaS products, automation systems, and AI-powered applications. I enjoy building products where AI is part of the core workflow, not just an extra feature. Your idea that the quality should live in the system instead of depending on individuals is exactly how I like to design software.

I'd love to learn more about Northstone and see if we're a good fit. I'll send you an email as well.

Hi Bernard,
Northstone is one of the most interesting co-founder opportunities I've seen here. My background is a bit unusual: competitive programming, math olympiad training, and building logic-heavy operational systems where process automation and edge-case handling were critical. What particularly caught my attention was your idea that the quality should live in the system rather than in individual bookkeepers. That way of thinking resonates strongly with how I approach software and system design. I'd be happy to discuss whether my background could be valuable on the product and engineering side. Best regards,
Dany

Hi Bernard,

Nice to see a founder already generating revenue and talking about customers instead of just ideas.

I'm a Senior Full Stack Engineer with 10 years of experience building SaaS products, AI applications, and backend systems. I recently started consulting and spend most of my time building products with TypeScript, React, Next.js, Node.js, and AI tools.

Your approach to combining AI with accounting operations makes sense to me. I also like that you're focused on building a real business first and using that to fund the larger vision.

I'd be happy to learn more about Northstone and see if there's a fit on both sides.

Thanks,
Carlo

Hey Bernard,
have you considered hiring a fractional leader until you really have the need for someone permanent? This will help you avoid splitting company ownership just now...

Smart move. One thing I've noticed watching accounting workflows is that even in heavily automated firms, the communication layer still eats up a ton of time. Client emails, inquiry responses, report narratives. That stuff is still manual typing even when the bookkeeping engine is fully automated. I built DictaFlow to handle that part. Hold-to-talk dictation that types wherever your cursor is, about 3x faster than the keyboard. Might be worth adding to the platform roadmap at some point. dictaflow.io

Hi Bernard,

I came across your Indie Hackers post and the thing that caught my attention wasn't the AI angle or even the accounting market.

It was this line:

"The quality lives in the system, not in any individual."

That is exactly the kind of problem worth building.

My background is in full-stack development, automation systems, AI integrations, workflow orchestration, and building products from zero to production. Over the last few years I've increasingly focused on designing systems where humans supervise the process rather than perform every task manually.

What I find interesting about Northstone is that you're not trying to replace accountants. You're trying to codify accounting expertise into a repeatable system that can scale while maintaining quality. That's a much more defensible approach than most AI accounting startups.

A few thoughts I had while reading your post:

The bookkeeping engine and the future ERP platform are fundamentally the same product if the underlying accounting data model is designed correctly from day one.
Human review should become a measurable control layer rather than a manual workflow.
The most valuable asset may ultimately be the structured accounting knowledge and decision system that gets built along the way.

From your side, you already bring something many startups lack: paying customers, industry expertise, and a clear path to revenue.

I'd be interested in learning more about:

Your current client acquisition process.
How much of the bookkeeping workflow is already systematized.
What the next 12-24 months of product development look like.
Your expectations around technical ownership and equity structure.

If there's alignment, I'd be happy to discuss how I would approach building the engineering side of Northstone.

Best regards,

David

$2.8K MRR before looking for a technical cofounder is a way stronger spot than most posts here, you're negotiating from revenue not a deck. the thing i'd be upfront about early is equity, a profitable services biz with a product roadmap pulls really different people than a pre-revenue idea, and the good technical folks will wanna know if they're building the ERP dream or babysitting the bookkeeping engine that pays the bills. kind of two different cofounders tbh. anyway, hows the split looking given you're already cashflow positive, idk if you've even got there yet

Hi there, interested in this. Here's a MVP of cool B2B SaaS product I built recently => wholetrade

The "quality lives in the system, not the individual" framing is the most interesting thing in this post - that's the actual product, and it's a harder problem to solve than most AI accounting tools acknowledge.
One question worth thinking about for the co-founder search: the Denmark market is relatively small and the roadmap ends at an ERP platform, which is a very different engineering challenge from the bookkeeping engine. Are you looking for someone to build the current product well, or someone who wants to be there for the full 10-year arc? Those are different people.
Congrats on profitable early traction - that's a real foundation to recruit from.

I've done work for OpenAI, Hulu+, and a ton of other companies, I've got over a decade of expereince as a software engineer with hands on experince with AI and building Agentic systems, would love to chat.

Hi Bernard,
One line got me: "the quality lives in the system, not in any individual." That's not a product feature, that's an architecture constraint , and the hardest one to actually build.
Here's what it actually means at the implementation level: your close engine can't just extract and route. Every decision the AI makes - VAT categorization, accrual logic, period matching - needs a traceable reasoning chain that a licensed bookkeeper can audit and stake their signature on. That's the difference between an AI that produces correct outputs and one that produces reviewable outputs. Most teams build the first and wonder why the human reviewer hates using it.
I've built this exact pattern in production and have worked with US and EU clients , AI outputs with step-level explainability feeding into a credentialed human approval layer. The architecture decisions there map directly to what you're describing.
On the ERP roadmap: the data model you design for bookkeeping will either enable or fight that pivot. That's a decision you make at month one.
Full-stack, AI-native, comfortable owning a codebase end to end. Have shipped production systems solo. Would love to explore it more with you !

Hi Bernard,

This looks like a solid opportunity. I'm a mobile/full-stack developer with strong experience shipping production apps most recently SleepViz , an iOS app I built and launched solo.

I'm comfortable owning a codebase end-to-end and building AI-integrated systems. You can see my work on GitHub: YounesseElkars

I don't have accounting knowledge, but from what you describe, I don't need to you own that half. I'd focus on turning your logic into reliable, scalable product.

Happy to jump on a call if you think there's a fit.

Hi Bernard,

I’m very interested in the technical co-founder opportunity for Northstone. Your AI-native accounting platform and profitable model are impressive, and I have experience building full-stack AI-powered systems, automation pipelines, and end-to-end product development, which aligns well with your roadmap.

I’d love to learn more about the role and discuss how I could contribute to building the product side. Could you clarify the structure of the paid component versus equity? I want to ensure there’s a sustainable balance as we grow the platform.

I will wait for your message.
Best regards.

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.
