Show HN: I built AI that turns 4 hours of financial analysis into 30 seconds

I built Duebase AI to solve a problem I kept running into in fintech - analyzing UK company financial health takes forever. The process usually goes: download PDFs from Companies House → manually extract data to spreadsheets → calculate ratios → interpret trends. Takes 3-4 hours per company and requires serious financial expertise. The technical challenge: Companies House filings are messy. Inconsistent formats, complex accounting structures, missing data, and you need to understand UK accounting standards to make sense of it all. My approach:

Parse 15M+ UK company records from Companies House API Built ML models to extract and normalize financial data from varied filing formats Created scoring algorithms that weight liquidity, profitability, leverage, and growth trends Generate 1-5 health scores with explanations in plain English

What it does:

Instant financial analysis of any UK company (30 seconds vs 4 hours) Real-time monitoring with alerts for new filings/director changes Risk detection that catches declining trends early No financial background needed to understand results

The hardest part was handling the data inconsistencies - UK companies file in different formats, use various accounting frameworks, and often have incomplete information. Had to build a lot of data cleaning and normalization logic. Currently focused on the UK market since I know the regulatory landscape well, but the approach could work for other countries with similar public filing systems. Link: https://duebase.com

Also under the heading “Comprehensive Accounts Analysis” you have “RetryClaude can make mistakes. Please double-check responses.”

From the footer:

“Instantly create your dream vacation with Duebase AI, where AI-driven precision meets personal preferences. Tailor-made travel plans crafted just for you, effortlessly.”

Did you pivot?

Looks like OP still does that: https://news.ycombinator.com/submitted?id=superproton

If we want to be charitable their previous website may have served as a template.

Well, at least this one made it to the front page!

I use Companies House (CH) a fair bit so interesting, tried out:

- There is UX issue here as on first pass it just looked like a view to CH, the scores where N/A, after a minute it came to life with something useful but during that period wasn't sure what was going on, you need to manage the user and let them know its working out scores not show N/A.

- Liked the history of scores as well, perhaps a chart would be good here.

- I need to understand how you score before I would ever consider paying for this, there has to be some explanation of the methodology.

Any stats on hallucinations or just general inaccuracies in the final results it generates?

Seconded. Throwing a bunch of data into an LLM and calling the result financial analysis is one thing, the results being at all trustworthy and valuable is another. I’d like to see an independent piece of analysis compared to this bot’s output for the same company and the original data.

On an even more basic level, throwing data at an LLM and telling people you "built an AI" pretty much blows any chance of anyone taking the results seriously.

UK company filings are already marked up with machine readable, structured, standardised tags. It's called XBRL. So it doesn't necessarily need a LLM to parse.

Wrong, my friend, that is only for small companies, big companies accounts are only available in PDF. Plus, in any case you have the raw data, here you have a full financial analysis.

Using an AI for this is like using crypto to pay for something: only done for the novelty

Regular coding, the SECs API (or UK equivalent), and some simple spreadsheet formulas have already done the brunt of this for years now.

Aren't there services that provide normalized financial data? I don't know about the UK, but I've seen in other markets. If your USP is more towards analytics than data wrangling, it might save you a lot of headache to offload that to someone else.

The heading text is cut off by the top navigation (on mobile safari).

Hey I had an example URL in a README.md with github.com/yourusername. I think this is going to bite me in the ass if anyone checks the commit that fixes it.

There's a copy pasted "Retry Claude" sentence in the copy of the page, the footer advertises unrelated travel services. Oh, and there's no details on what methods the AI uses for analysis, or any measurements at all of an unproven AI analysis tool.

This is pretty bottom of the barrel.

Thank you Claude, good job!
