Descripción del empleo

Context

Earlier this year, I sold my previous company. Since then, I’ve been running a series of structured experiments to figure out what I want to build next. I’ve done experiments in enterprise B2B, e‑commerce, SaaS and sales tools. Two of the latest experiments are at the bottom of this post for context.

I can run solo, but I’m convinced it will be faster, more fun, and more successful with the right co‑maker.

So I’m looking for an experienced partner who knows the ins-and-outs of at least one industry and has already done something interesting. You can build, sell, and market – but you’re exceptionally strong at building. You like simple, sharp products, fast validation, and small teams, and you intrinsically care about big‑picture moves rather than micro‑optimisations.

No need for a full leap on day one, but minimum 2‑3 days per week and enough financial stability to explore without relying on a salary.

What we will do

Run rapid validation experiments for focused, single‑feature products

Products that help people make money, save money, or save time

Ideally in a niche or sector that we are highly familiar with

Principles for ideas I’ll pursue

• Simple enough so that it’s possible to build a sellable MVP in under 10 days
• 10x cheaper or 10x better than current alternatives
• Single‑feature, easy‑to‑understand products with PLG and light sales touches

Fit examples

• Painkillers solving a real, recurring problem
• Scratching own itch
• Automation of repetitive niche tasks
• Unbundling a bloated tool into one sharp feature
• Distribution‑led concepts
• Painful problems in boring niches

Not a fit

• “Cool” tools without a painful problem
• Build‑it‑and‑they‑will‑come ideas
• Slightly better clones with no twist
• One‑time‑use utilities
• Seedy and unethical markets
• Low‑priced B2C
• Complex, heavy SaaS
• Difficult business model mechanics
• Passion projects with no market
• Consulting or agency work disguised as product
• Enterprise products and services

Already have something

If you’re already working on something that you think fits these criteria, I’m keen to learn more!

Ambitions and working style

Fast and highly organized minimal entrepreneurship

Scientific and structured approach to product and growth

Fully remote, with optional occasional in‑person work weeks

Tiny, multi‑disciplinary founder team of 2 (maybe 3) plus flexible freelance support

Bootstrapped

Low ego : best ideas win, no politics

Targets after 1 year : 50k MRR, >

80% margin, equal split

Validation strategy

Budget : ~€2-5k per idea

Timeline : 2 weeks to complete each cycle

Deliverables per cycle :

• a. A landing page that looks like a real product (can be a high‑fidelity mock)
• b. Three distribution experiments (e.g. SEM, display, cold outreach)
• c. Analysis and a clear next‑step decision

Next step

Latest experiments

My most recent completed experiment was Opclaro.com. It started as an idea to help remote teams share better feedback, but through dozens of validation calls it grew into an enterprise solution... The market signals were strong, but the enterprise conversations agonized me. It helped me realize that I do not want to be involved with enterprises.

Right now, I’m testing Adwedge.com. Early signals are mixed — a 1% CTR on a €300 display test and a 4% positive rate on direct outreach — good, but potentially too limited “painkiller” pull. I’m currently running two more experiments to confirm or kill it.
