Right now I am between builds, meaning my brain goes into founder problem-finding mode. The result. I generate many more ideas than I could ever implement.
On their own these ideas are worth little. In fact, they might present a net negative. Chasing an idea without executive discipline and a strong business model is just wasted energy and effort.
But letting them sit in notebooks or back of scraps of paper feels wrong. I instead want to share them here. Some are raw, some are more polished. None is exactly the right match for me, but they could be for you.
My hope is simple, inspire and put ideas out there I would love to have in the world. In any case, if any of them resonate with you reach out. For some I know exactly how to start, for others not so much. But I’ll be happy to share my thinking and give sparring when useful.
Idea 1 – pension-info -> bo-info
The Problem
Settling an estate in Denmark is still highly manual. Despite the fact that almost everything is tied to the CPR number, heirs and lawyers must piece together bank accounts, pensions, insurances, and tax data through a fragmented process. The result: cost, delays, and stress for families at a difficult time.
The Analogy
When Danish pension providers created Pension-info, they solved a similar problem. Aggregating information from multiple providers into one unified view. The same principle could apply to estate settlement: a Bo-info.
The Solution
A central digital service that automatically collects estate information via CPR, codifies the legal handling (private vs. public settlement, will conditions, tax implications), and automates the estate split according to Danish law.
Market Size (back of the envelope)
- 55–60,000 people die in Denmark each year.
- ~60% handled as “privat skifte.”
- ~30% of those hire a lawyer (~20,000 DKK typical fee).
- If a startup captures 20% at half-price (~10,000 DKK), that’s ~1,980 cases → ~19.8M DKK in annual revenue.
Challenges
- Stakeholder complexity: courts, Ministry of Digitalisation (MitID), SKAT, financial institutions.
- Data governance & privacy: estate data is deeply sensitive.
- Incentives: large law firms may actively resist, as this eats into straightforward revenue.
- Politics: implementation would touch justice, taxation, and digitisation ministries simultaneously.
My Notes
Execution difficulty lies less in tech, more in politics and stakeholder orchestration. The process is highly codified by law → lends itself to automation. Potential to expand beyond Denmark once proven.
Idea 2 – Acoustic gut health monitoring
The Problem
Gut health is rising in awareness, yet measurement is crude. Today the main option is stool microbiome sequencing. It is invasive, inconvenient, and lagging. It provides only snapshots, missing real-time digestion dynamics. For people with chronic gut issues (IBS, bloating, constipation) or those seeking wellness insights, there is no continuous, non-invasive way to monitor gut function.
The Analogy
Continuous glucose monitors (CGMs) transformed diabetes management by moving from episodic blood tests to real-time feedback. Wearables like Oura and Whoop did the same for sleep and recovery. The gut is still stuck in the “stool sample era.” Gut acoustics can, like heartbeats in cardiology, be continuously measured and interpreted.
The Solution
- A wearable gut-sound patch:
- Passive mode: listens to natural peristalsis, gas, and fluid movement.
- Onboarding: daily wellness annotation to establish a personal baseline.
- Adaptive AI: correlates sounds with perceived gut states, then predicts and asks for user confirmation → self-learning loop.
- At scale: baseline data simplifies onboarding; the system offers digestibility scores, stress-digestion alignment, and early warnings of sluggish or hyperactive motility.
- Future: hybrid passive + active sensing (echolocation/ultrasound) for higher signal-to-noise and richer data.
Market Size (back of the envelope)
- TAM (global digestive health + wearables): ~$15–20B.
- SAM (biohackers, IBS/IBD sufferers, microbiome test buyers): ~$2–4B.
- SOM (early adopter wedge): 100–200k users in US/EU within 3–5 years.
Device: ~$250. Subscription: ~$20/month. Revenue potential: ~$50–100M ARR.
Challenges
- Signal quality: gut acoustics are subtle, variable; require careful filtering.
- Clinical validation: need datasets large enough to prove predictive power.
- User comfort: patches/belts must be discreet and wearable long term.
- Regulation: if marketed as medical, FDA/EMA scrutiny applies; wellness route is lighter but still sensitive.
- Stakeholders: physicians, insurers, supplement/food companies, wellness ecosystem.
- Education: consumers must understand what a “gut wellness score” actually means.
My Notes
Execution difficulty lies less in hardware R&D (which is feasible with off-the-shelf sensors) and more in data collection and validation at scale. It would need a staged rollout. Starting with wellness and quantified self users, then more into more and more mainstream consumer device as data and evidence grows. Key hypothesis is that there is a significant concordance between sound and health relevant parameters.
