How it works

From profile to first conversation

You say what you’re looking for, browse profiles, and talk only when both sides are interested. No cold messages. No networking “just in case.”

Say what you’re looking for

Choose your role, your goal, and the people you want to meet. From the start, you know what you’re looking for.

Meet the right people

Browse profiles and quickly decide who you want to connect with. Interested in someone? Let them know.

Start the conversation

When interest is mutual, a conversation opens. No writing to people who aren’t interested.

About us

Built by founders, for founders

Foundersi was born from a simple observation: a good idea is often just the beginning. To move forward, you need the right people with specific skills, experience, energy, or simply a similar drive to act.

That's why we built an app that makes it easier to find people you can start building something with. Whether you have your own idea, are looking for a business partner, need specific skills, or want to join an interesting project.

We want to create a place where people connect around ideas, skills, and a real willingness to act. A place where a conversation can be the start of collaboration, and collaboration, the start of success.

Roles

Four roles. One app.

An originator is someone with an idea for a project, product, or business who wants to move from concept to action.

You might already have initial assumptions, a prototype, or just a direction you want to test. You don't need every skill or a ready-made team.

In Foundersi

In Foundersi you can look for people who'll help fill what your project is missing today.
