Personal relationship OS Built in Europe

Use your contacts
with context.

YELO is the intelligent address book that helps you give the many people you already know the attention they deserve. Think of your contacts app, reinvented.

No spam. We write when there is something worth saying.

You built your network
persistently.
Now tend it.

Who it's for

Not for everyone
with contacts.

For people who know what their contacts are worth. A network is the most consequential professional asset most people own — and a well-maintained relationship is worth more than a hundred cold ones.

YELO is for founders, advisors, investors, consultants, architects, agents, CEOs, producers, freelancers, promoters, journalists, curators, operators, politicians, lawyers, connectors, scientists and entrepreneurs.

Moments where YELO earns its place

Six moments that make a difference. Every day.

Before a meeting
A briefing, not a profile.
01

Before a meeting

Open YELO five minutes before. It surfaces who they are to you — not a LinkedIn profile, but your history with this person: where you met, what you discussed, what you promised to send, what has changed in their world since. You walk in prepared, not reconstructing from fragments.

02

After an event

A voice note on the way home — a name, a detail, an intention. YELO saves it to the right contact, holds the timeline steady, and makes sure a promising conversation doesn't become a vague intention.

03

Connecting two people you know

Two people in your network would benefit from knowing each other. YELO helps you match them easily — based on complementary goals, shared ground, the right moment. It drafts the introduction — contextual, warm, in your voice — so you bring the right people together with a single note, without spending a lot of time.

04

When you want to mobilise a group

A dinner. A launch. A considered ask to a small group of people you actually know. Describe what you need — by city, sector, or trust — and YELO builds the list. You write once, and it helps you send with the care each relationship deserves.

05

Staying in touch

You cannot maintain every relationship properly — and you should not try. YELO reads your history and context to surface the very few follow-ups, birthday wishes and catch-ups that actually matter right now. Not a list. A considered suggestion.

06

Research your relationships

Have a conversation with YELO. Ask who you know in a city, a sector, an industry or a specific profile you're looking for. Request a draft, a list, a brief, an analysis. YELO draws only from what you know — your contacts, your notes, your history — and the sources you connect: Mail, LinkedIn, and more.

In detail

What YELO does for you

The full inventory behind the six moments — in plain terms.

  • A clean, elegant address book that stays in order
  • Notes that stick — people, context, preferences, projects, per person
  • Voice notes with transcription, captured in seconds
  • Meeting and call summaries saved to the right contact
  • A simple timeline of touchpoints and context
  • Natural-language search across your own memory — “who did I meet through…”, “people in…”, “who to follow up with…”
  • Gentle prompts for check-ins, follow-ups, congratulations and open loops
  • Draft messages you can edit and send in your tone
  • Lists for outreach — invitations, updates, smaller group mailings, built from your criteria
  • Introductions supported by relevant context, not guesswork
  • Relationship insights and network analysis drawn from what you choose to connect

Just ask

Ask in plain words. YELO answers from what you already know.

“Who do I know in Berlin working in corporate law — or who could introduce me?” YELO draws only on your contacts, your notes and your history — never the open web.
