The Swarm alternatives, by what you need from the network

What The Swarm does well

The Swarm deserves an accurate description first, because for the right team it is a very good product.

Its core is relationship data. It maps overlaps across a large database of public profiles, including shared employers, schools and investors, and tells you who on your team or among your backers might reach a target. You can add stronger signals by connecting LinkedIn, email and calendar.

It also has a practical answer to the hardest part of this category, which is getting investors and advisors to take part. An admin sends a request, and the person opens a portal with no account and shares their LinkedIn connections. On top of that sit intro requests, integrations with tools such as HubSpot, Clay and Attio, an API, and a connector for Claude and ChatGPT.

If you have a go-to-market team that wants to build relationship data into its own workflow, that is a strong package, and it may be where you should stop.

Why people look elsewhere

They wanted the introduction more than the data. A map tells you a path exists. Someone still has to decide who asks, write the note, chase it and record what happened. The Swarm does offer intro requests, but its center of gravity is the data. Boomerang makes this argument about The Swarm, and it sells the alternative, so weigh it accordingly.

Coverage depends on who shares. Public overlaps are easy to get and often weak, since two people at the same large company may never have met. The stronger paths need people to share their connections, and some investors and board members will not get around to it. This is true of every tool here that uses private data, The Swarm included.

Public data needs checking. The GTM Directory notes that accuracy needs manual verification. That is a fair cost for this kind of dataset, but it matters if you plan to act on a path without a second look.

They are not building anything. An API and a large dataset are worth a lot to a team with an operator who will use them. One founder and three advisors may never touch them.

If you want a graph inside your CRM

Connect The Dots scores relationships from two-way email and messages rather than public overlap, and syncs with Salesforce and HubSpot. Outside people such as board members and investors can join and share with the team, and approval rules can route their requests through a chosen owner. It suits a sales team that lives in its CRM. Its company-wide setup connects employees' accounts through an admin, so raise that with your team before you turn it on.

If you want plain-language search across people you know

Happenstance searches your network in plain language and lets groups of friends or colleagues search each other. It is a good fit for someone who asks a different question each day and wants a quick answer. It is lighter on the data products a team might build on.

If you want paths and outreach together

Village combines the networks people sync with public mapping of their contacts' connections, and adds search, screening and an outreach pipeline. It suits a team that wants one place to find a path and act on it. Since part of its reach comes from inference, check a path with the person before you rely on it.

If you want the introduction managed for a sales team

Boomerang focuses on running the introduction, from choosing who should ask through drafting and reporting. Its material is written around revenue teams with investors and boards to activate, often at later stages and larger deal sizes. A seed-stage founder may find it is built for a company they have not become yet.

If you are a firm

Affinity is the standard for venture and private equity. It captures relationship activity across the firm and scores it. Bridge is built for platform teams that take many intro requests and route them, and we cover it in Bridge alternatives.

If you are a founder or advisor who wants backers in control

NetworkOS comes at this from the person who owns the relationship. A founder creates a one-way team and invites advisors and investors, each of whom links their own account. The founder searches what they share, from the web app, Claude or ChatGPT, and sees a limited view with no email addresses or notes. Each request goes to the advisor to approve, and the introduction is sent from the advisor's own inbox with the replies tracked. Advisors also use it for their own network.

The weak spot is reach. Nothing is inferred from a public database, and there is no large dataset to build on, so a backer who does not join adds nothing. Asking each backer to set up an account is more to ask than The Swarm's portal, so The Swarm is likely the better choice if your backers will share a list and nothing more.

How to choose

If what you really need is a way to keep up with your own contacts, none of these is the right starting point, and the best personal CRM for networking sorts those tools by the job they do. Otherwise, answer three questions before you start a trial.

What will your backers actually do? Ask two of them. Sharing a file, joining a product and approving requests are different asks, and their answer rules tools in or out.

What happens after you find a path? If your team already has a process for introductions, data may be enough. If nobody owns that step, buy for the step.

Who will run it? A tool with an API needs someone to use the API. A tool built for a sales team needs a sales team.

Then test each one on ten real target accounts, and ask the people named whether the path is real. That one check tells you more than any comparison page, this one included.

The short version

Stay with The Swarm if you want data to build on. Connect The Dots fits a CRM-based team, Happenstance fits quick search across people you know, and Village fits paths plus outreach. Boomerang fits a sales team that wants the introduction managed, and Affinity and Bridge fit firms and platforms. NetworkOS fits a founder or advisor whose backers should approve every request.
