CTD is a network platform — the more people in your network, the more paths you can find and the more connectors you have available. Inviting people you know to join CTD is one of the most effective ways to increase your reach, especially when those people have strong networks in the areas you're trying to reach.

How inviting works

When you invite someone to CTD and they join, their connections become paths you can use. If your friend knows the VP of Sales at a company you're targeting, that path shows up in your search results. You can then ask for an introduction — or create a ghost email for them to send on your behalf. And they can do the same for you.

CTD is free for individuals, so there's no cost barrier for the people you invite. They get the same network search and path-finding capabilities as you do.

How to send an invite

  1. Go to app.ctd.ai/invites (or click Invites in the left sidebar).
  2. Click Send invite and enter their email address — or click Copy link to share your personal invite link however you like.
  3. They'll receive an email with a signup link.

Once they join and connect their email, their network merges into your graph and new paths become visible immediately. You can track who has joined and who still has a pending invite from the same page — and send a reminder to anyone who hasn't signed up yet.

Recommended to invite

CTD surfaces people it already knows you're connected to who haven't joined yet. You'll see these in the Recommended to invite panel — a quick way to find high-value additions without having to think of names yourself.

Who to invite

The most valuable people to invite are those with strong networks in areas that matter to you — not just people you're close to. Think about:

  • Friends who've changed industries or companies — they carry relationships from multiple contexts, which means more diverse paths.
  • Advisors and mentors — their networks often include exactly the senior relationships that are hardest to reach cold.
  • Former colleagues — people who've moved to companies you care about can open doors there.
  • Superconnectors — people with large networks add a disproportionate number of second-degree paths to your graph.

Mutual benefit

When you invite someone and they join, the value flows both ways — they can also see paths through your network and ask you to make introductions for them. CTD works best when both parties are active, so inviting people who will actually use it matters more than volume.

On Business or Team Edition? You can also add external members — investors, advisors, board members — who connect to your team's workspace without being full team members. See What are external members? for how this works.
