ERES Invest
A private-healthcare M&A intelligence platform that maps and scores every private care operator in Sweden: property ownership, group structure, financial risk and expansion potential, all on one interactive map.
Software and AI studio · Based in Gothenburg and Stockholm
We build systems that do the job, and show how.
Power O&N System builds its own subscription products like Stadgia and Varde, websites that get found on Google and in AI answers, and custom systems that clients build into their own operations.
Welcome to the Power O&N System
Stadgia, ERES, InstaPitcher and the websites for Equity Dynamics. After the film you can explore the same system yourself below.

From raw data to production
How a document becomes decision support
An example of what our systems do: raw data comes in, gets structured, is checked and used in a system that runs in production.
- 01Raw data
Annual reports, minutes and registers in different formats.
- 02Structure
Fields are extracted and become clean, structured data.
- 03Check
Every value has a source and is tested against real data.
- 04In production
The system is used every day, not just in a demo.
Illustration. This is how InstaPitcher, for example, works with financial documents.

Three ways to work with us
What we do
Four disciplines, one standard: production-grade or not at all.
Custom systems
We build AI and data systems for your business and hand them over running in production. The system can carry your own brand.
- Examples
- Prospecting AI that finds and qualifies companies
- Research AI that compiles findings with sources
- Logistics and resource planning systems
- Machine learning, data pipelines and search engines
- Good fit for
- Companies with manual work that does not scale, or data that goes unused.
- Pricing
- Fixed price per stage after a discovery phase. For the right company, part of the fee can be taken in equity.
Web and visibility
We build new websites and improve existing ones so they get found on Google and in AI assistants like ChatGPT and Perplexity.
- Included
- Website design and development
- SEO and AI search: structure, schema and content
- Measurement from day one
- A starter pack of social media content
- Good fit for
- Companies whose website does not bring in enquiries.
- Pricing
- Fixed project price after a quote, typically SEK 20,000 to 50,000. Ongoing SEO and social media as a monthly service.
Ready-made systems
Software we have finished building and sell as a subscription. The first is Stadgia, for board work in associations. More are on the way.
- Available
- Stadgia, for housing cooperatives, joint property associations, economic and non-profit associations, and limited companies.
- Pricing
- Subscription from SEK 99 per month.
- Coming
- More ready-made systems launch shortly.
Projects & joint ventures
Projects we build, and partners we build them with.
Systems we have designed, built and shipped together with our partners, from live products to self-learning models running in production.
CRM system for VTW
A custom CRM built around VTW's real workflow: pipeline, contacts and follow-ups in one place instead of scattered tools and spreadsheets.
AI press-release generator
An AI tool that turns a few structured inputs into a clean, publication-ready press release in seconds, written in the company's own voice.
Financial-document extraction ML
Self-learning ML models that read European financial documents (iXBRL, PDF and JSON) across national registries and convert them into clean, structured data. Validated field by field against labelled test sets, reaching up to 99–100% accuracy on the document types we have tested.

Know what the board must do, and why
Stadgia keeps an association's requirements, decisions, inspections and documents in one place. Dates are calculated from the association's own financial year, and every requirement links to its source in law.
Requirements and dates with sources
AGM, annual report, audit and inspections in one annual cycle.
An AI assistant that shows its sources
Answers only from the association's own documents, with a reference after every claim.
Cases from members
Fault reports, motions and petitions reach the board.

About us
We started PowerOnSystem because shipping real AI shouldn't feel like herding cats.
We're a small team that builds machine-learning systems, trading algorithms, data pipelines, and search engines for companies that need them to actually work in production, not just in a notebook.
Ship what survives
A model or strategy only counts once it holds up on live data.
Radical visibility
Shared status, shared artifacts, no black boxes.
Rigor over hype
Backtests, evals, and honest baselines before bold claims.
Frequently asked
Frequently asked
Four disciplines, one standard: production-grade or not at all.
What does PowerOnSystem do?
We build machine-learning systems, trading algorithms, data pipelines, and search engines, and take them all the way to production. We are a software and AI studio, not a solar or hardware company.
What kinds of projects do you take on?
Typical work is data cleaning and structuring, a scoped AI/ML pilot on real data with a measurable goal, putting a model into production against your existing systems, and ongoing operation and monitoring.
How do you price your work?
In fixed-price stages, so there is no open-ended consulting risk: a scoped pilot with written acceptance criteria, then a production step, then optional operation and monitoring. You always know the price up front.
How fast can you deliver?
Pilots are measured in weeks, not months. We agree the acceptance criteria before we start, so 'done' is defined in writing from day one.
Where are you based?
We are based in Göteborg and Stockholm, Sweden, and work with clients across the Nordics, on-site or remote.
How do you handle data privacy and AI regulation?
EU/EES data handling, a data processing agreement from day one, and no training on client data. AI features are built to meet transparency requirements under the EU AI Act.
