Ussembly
The "I know a guy" app

We all know a guy.
Ussembly makes sure you always do.

When someone needs a plumber, a real-estate agent, or a contact in a new city, there's always that person who says "oh, I know someone." Ussembly remembers who you know, what they're into, and how they can help — so the right person is always a search away.

Why we built this

We all "know a guy" — but that talent, know-how, and experience is scattered and half-forgotten across your phone, and the moment you actually need it, you can't remember who. We can all relate to the missed opportunities and headaches that could have been avoided if we'd known the person we needed was a phone call away the whole time.

Not a social network — your real one, made useful.

Three tools, one trusted network

Remember who does what, discover them across your network, and reach them around a shared goal.

AI Contact Manager

Transforms your contacts into a searchable resource directory — the skills, experience, and know-how you'd otherwise forget.

Network Search

Ask "who do I know who knows about ___?" and search your extended network securely and privately. Don't know the right person yourself? Find the friend of a friend who's exactly right — and ask for an intro.

Project Helper

Got the spark of an idea, or already building something? Ussembly finds the people who can help you get where you're going.

How Ussembly works

Ussembly is designed to be simple. On its own, it's a next-level searchable contact manager that remembers who does what, so you don't have to. And when you connect with friends and associates on the platform, you build a trusted resource network that grows stronger and more powerful with every new member.

1

Sign up

Install the app, verify your phone number, and you're ready to go.

2

Capture knowledge, big and small

Tag the people you know with what they do, what they've done, and where they've been. These small details become your network's memory — so you don't have to keep it all in your head.

3

Build a resource network

What are you good at and willing to share? Have a hidden talent few people know about? Tag yourself, connect with the people you've tagged, and invite them to do the same. You control exactly who sees what — and who can reach you. See Privacy.

4

Got an idea or project in mind?

Whether you need a gut check on an early idea or trusted partners to move a real venture forward, Ussembly helps you assemble a brain trust to guide your path.

Privacy and Security By Design

Privacy is a foundation, not an afterthought. Ussembly collects only what's needed to connect you with your network — you stay in control of the rest.

No analytics or tracking

We don't profile you or follow you around.

Your personal information stays on your device

You're identified only by an encrypted version of your phone number, and you connect over secure, encrypted channels.

Connection requests are delivered outside the app

When connecting with someone new, Ussembly creates the connection link — but you send and receive it through your regular messaging app, so you only connect with people you actually know. The extra friction is a feature, not a bug.

You decide who sees what

You control who can find you, and for what. Accept the tags that fit, decline the ones that don't.

Visibility A tag you accept A project you create
Private Only the person who tagged you Only you
Friends Friends you and they have in common* Your friends on Ussembly
Network Friends of friends — up to 2 hops away Friends of friends — up to 2 hops away
Public Anyone on Ussembly Anyone on Ussembly

* Tags you give yourself start at Friends by default — open them wider whenever you like.
