About undrsight

We're building the software
M&A professionals
wish already existed.

undrsight is a Brussels-based company started by two co-founders: an M&A advisor with two decades of transaction experience and a deal-analytics engineer. We started this because we were tired of watching analysts spend the best years of their careers copying data between spreadsheets. The work deserves better tools.

Our thesis

Due diligence is not a "knowledge worker" task that AI should replace — it's a judgement task that AI should supercharge. The problem isn't that deal teams are slow. It's that 95% of their time is spent reformatting information instead of interpreting it.

We think the right way to solve this isn't a chatbot with file upload. It's a vertical operating system for the deal: workspace, parsing, workstreams, findings, reporting — all end-to-end, all citing every claim, all built for how senior partners actually read memos.

That's undrsight.

The story so far

From spreadsheet to software.

2023

The frustration that started it.

Mansour — five years deep in business analytics for transaction workflows — kept watching the same pattern: analysts spending most of their week reformatting data instead of forming a view on it. The insight wasn't that the work was hard. It was that most of it wasn't judgement. It was parsing. So he started building a tool to do the parsing.

Aurora release.

The platform you see today: multi-tenant workspaces, parallel workstream analysis, IC-grade reporting, Slack / Teams integrations, and a documented data lifecycle.

Next

Expand coverage — not customers.

Our thesis is that we'd rather have 50 firms using undrsight on every deal than 500 firms using it occasionally. 2026 goals: deepen sector coverage (healthcare, energy, infrastructure), add post-close monitoring, launch the audit module.

The team

Who's building this.

Two co-founders. We hire when the work demands it — not when a burn model requires it.

How we work

Four things we care about.

Judgement over automation.

Our job is to compress grunt work so senior people can spend more time thinking. We'll never position this as "AI doing diligence for you." That framing is lazy and it's also wrong.

Citations over confidence.

We'd rather show an uncertain finding that's linked to a specific document page than a confident-sounding summary nobody can verify. Sourceless AI output is technical debt.

Paid pilots over vanity logos.

We don't give the product away to get names on a slide. If a firm won't pay for a pilot, they're not serious about switching — and we'd rather invest attention in firms that are.

European by default.

Our data lives in the EU. Our team is in the EU. Our DPA is GDPR-native, not retrofitted. We're built for the regulatory reality our customers operate in — not a San Francisco version of it.
