Sell Seashells
Software for the moments people cannot afford to forget.
Sell Seashells is the project home of Merlin Brouwer: a collection of founder-led products exploring relationship intelligence, learning systems, and tools for more thoughtful human interaction.
What We Build
Thoughtful software for high-value human interactions
Every product begins with the same question: how can technology help people be more thoughtful, more prepared, and more effective in their most important relationships?
Relationship Intelligence
Software that helps people remember, prepare for, and strengthen their most important professional and personal relationships.
Learning & Memory Systems
Tools for structured knowledge retention, spaced repetition, and personalised learning pathways that adapt over time.
High-Trust Communication
Products that support clearer, more reliable communication in environments where precision and trust matter most.
Featured Project
Attaché Privé
A personal relationship intelligence system designed to prepare users for important meetings with accurate memory, concise briefings, and adaptive personal intelligence.
Attaché Privé captures key insights from past meetings and creates evolving profiles to deliver concise, actionable briefings before every interaction. Built for founders, advisors, executives, and anyone managing high-trust relationships.
Principles
What guides every product we build
These aren't slogans. They are the constraints we apply to every design decision, every feature, and every line of code.
Discretion
The best tools work quietly. We build software that respects the sensitivity of the information it handles and the people it serves.
Memory
Human memory is unreliable. Our products give structure to what people know, so important details are never lost to time or distraction.
Trust
High-value relationships depend on trust. Every product we build is designed to deepen trust, not exploit it.
Clarity
Information should arrive when it is needed, in a form that is immediately useful. We prioritise signal over noise.
Human Judgement
Technology should support better human decisions, not replace them. We keep people at the centre of every interaction.
