Search for go-to-network software and you will find vendors who use the phrase and vendors who do the work without using it. This page sorts them by what they actually do, because the buying decision turns on that, not on the label.
Three categories, one job
The job is turning relationships into meetings, and it has three parts. Some products do one, some do two, a few do all three.
| Category | Question it answers | Typical data | Where it stops |
|---|---|---|---|
| Relationship intelligence | Who on our side knows whom at the target? | Email and calendar metadata, CRM, sometimes LinkedIn | At the map. Asking is left to you. |
| Champion tracking | Which past buyers and users just changed jobs, and where did they land? | Contact lists matched against job-change data | At the alert. Routing and asking are left to you. |
| Warm intro orchestration | Who should ask whom, with what note, and did the meeting happen? | The map plus signals, plus a workflow | At the CRM write-back. This is the full motion. |
A go-to-network motion needs all three questions answered. The practical test when evaluating any product: does it stop at the map, at the alert, or at the meeting?
Relationship intelligence
These products build the graph. They read email and calendar traffic, CRM history and sometimes public signals, and score how well each person on your side knows each person outside it.
- Introhive. The longest-established, strongest in professional services and law firms, where the use case is firm-wide relationship mapping and CRM data quality. Boomerang vs Introhive.
- Affinity. Built for venture and private equity deal teams: relationship strength scoring across a firm's inboxes, with deal pipeline on top. Affinity alternatives.
- Connect the Dots. Relationship mapping aimed at sales teams, with a graph built from employees' connections. Boomerang vs Connect the Dots.
- Nektar. Activity capture into the CRM with relationship signals derived from it.
Strength: the map is usually good. Limit: most stop at the map. Knowing that your board member knows the CRO is not the same as getting the meeting.
Champion tracking
These watch a defined set of people, past champions, users and buyers, and alert you when one changes jobs, on the logic that a known champion arriving at a new company is the warmest lead you will ever get.
- UserGems. Job-change tracking for past users and champions, pushed into sequences and the CRM. Boomerang vs UserGems.
- Champify. Similar motion, focused on champion job changes as pipeline triggers. Boomerang vs Champify.
Strength: a precise, high-converting trigger. Limit: one network (customers) and one signal (job change), with the ask still on you. For Boomerang's version of this play see champion tracking.
Warm intro orchestration
These run the introduction end to end: find the path, decide who should ask, draft the note, chase it, record the outcome.
- Boomerang. Maps the four networks (team, customers, investors and advisors, partners) from data the company already has, scores every path, and its agent Rudy picks the sender, drafts the ask and the forwardable blurb, chases it to a meeting, and writes the outcome back to Salesforce, HubSpot or Attio. Connectors send from their own accounts; Rudy never sends on anyone's behalf. Works in Slack and Microsoft Teams, on LinkedIn and CRM pages through a Chrome extension, and in Claude or ChatGPT through MCP. Plans from $80 a month, 7-day free trial. Armis created 26,000 warm-intro paths and saw 10x ROI on revenue booked in a year.
- The Swarm (formerly Commsor). The company that coined go-to-network. Maps a company's extended network, including investors and advisors, and supports intro requests. Boomerang vs The Swarm.
- Vieu. Positions as a business graph for warm paths into enterprise accounts, with intro workflows, and uses the go-to-network label. Boomerang vs Vieu.
Strength: the ask gets made and the loop gets closed. Limit: these products depend on how much of the network they can see, so the data sources each one reads is the first question to ask.
How to choose
Four questions settle most evaluations:
- Which networks does it see? Team only, or team plus customers, investors and partners? A product that maps employees' inboxes sees one network out of four.
- Does it pick the sender? The difference between a map and a motion is whether the product knows that a customer ask goes through the CSM and a board ask goes through the CEO.
- Who sends? If the product sends on anyone's behalf, connectors will not stay in it. If the connector sends from their own account, they will.
- Does it write back? If outcomes do not land on the account and opportunity, the channel cannot be measured against the others, and unmeasured channels get cut.
The definition of the motion itself is on go-to-network, and the comparison with cold channels is on go-to-network vs go-to-market.
Frequently asked questions
Is there a product category called go-to-network?
Not formally. Vendors who use the phrase sit in relationship intelligence or warm intro orchestration. Buy by the job, not the label.
Can a CRM do this?
A CRM records relationships you have already logged. It does not know that your investor sat on a board with the buyer, or that your champion moved. The map has to come from somewhere else, then be written back into the CRM.
Do these tools need connectors to upload their contacts?
Boomerang does not. Connectors are mapped from signals the company already has and public ones (work overlaps, past employers, board seats, portfolio companies), and their address books stay private. Some other products in the category rely on employees connecting their inboxes or LinkedIn.
Which category should a small team start with?
Warm intro orchestration, because it includes the map and the alerting and adds the part teams skip, which is the ask and the loop. A map on its own becomes a spreadsheet nobody opens.
