I run a LinkedIn prospecting agency, so I look at buying signals every week for a living. A buying signals tool watches public actions that show someone may be ready to buy (a job posting, a profile visit, a research spike on a review site) and puts those people or accounts in front of you before your competitors notice. This is my honest comparison of the buying signals software I would actually consider, sorted by who it fits.
Here is the short version. If you have a marketing team and a five figure annual budget, the account level platforms (Bombora, 6sense, ZoomInfo, G2) tell you which companies are in market. If you are a founder doing your own outbound, you want person level tools that publish a price and hand you a first line to write. Prices below were checked in August 2026, and I only quote a number when the vendor publishes one.
What buying signals software actually does
Every tool in this category does three jobs, and they are worth separating before you sit through a demo.
- Collect a signal. From a publisher co-op, a review site, your own website, or a public source like job boards and LinkedIn.
- Resolve it to a target. Turn an anonymous spike or an IP into a company, and sometimes into a named person.
- Deliver it somewhere useful. A CRM record, a Slack alert, a webhook, or straight into an outreach sequence.
Most tools are strong at one of these and weak at the other two. The account level platforms are excellent at collection and poor at delivery, which is why so much intent data dies in a dashboard nobody opens. For the difference between account signals and the individual signals you can act on, I broke that down in how to identify buying signals.
How to choose a buying signals tool
Six questions settle it faster than any feature grid:
- Where does the signal come from? Own network, publisher co-op, review site, your website, or a public source.
- Account or person? An account spike tells you a company is in market. It does not tell you who to message.
- How fresh is it? A weekly topic surge is a planning input. A profile visit this morning is a same day action.
- Who does it cover? Several tools resolve individuals in the United States only.
- How does the signal leave the tool? If it stops at a dashboard, it will not turn into pipeline.
- Is the price public? In this market, a published price is a strong sign the product is built for a team your size.

1. Sendable
Full disclosure: this is the product I am building with my cofounder, so it goes first and you should read this entry knowing that. Sendable watches a narrow set of LinkedIn signals (job posts, webinars, profile visits, first degree network activity), filters the profiles against the ideal customer you describe, and pushes the matches into a LinkedIn sequence you build in a visual workflow, with a shared inbox and multiple sender accounts. It is LinkedIn only, no email. Pricing is published: $49 per sender per month from 1 to 4 senders, $39 from 5 to 25, and $1,000 a month for unlimited senders. It is the right shape when the signal you care about lives on LinkedIn and you want the outreach to happen in the same place. It is the wrong shape if you need topic intent across the open web, or if your motion runs on email. You can see what it does at getsendable.io.
2. G2 Buyer Intent
G2 captures first party research from software buyers comparing products, categories, and competitors on its site. When accounts you care about read your category page or your competitor's profile, you get an alert. It is one of the cleaner high intent signals in B2B, because reading a comparison page is close to a decision. The catch is that it is account level and demo priced, and it only sees buyers who use G2. See the G2 buyer intent overview for what it tracks.
3. Bombora
The topic intent standard. Bombora runs a co-op of B2B publisher sites and turns content consumption into Company Surge scores by topic. Forrester named it a Leader in its 2025 intent data evaluation, per Bombora's own release. When another tool advertises "intent data", it is often Bombora underneath. It is anonymous by design, so it lands at the account level, and there is no price on the site.
4. 6sense
Predictive account scoring layered on top of intent, ads, and orchestration. It is built for a revenue team running an account based motion, with an admin and a CRM someone maintains. Powerful, and heavy. Below roughly ten people in go to market, it is more platform than you can feed. No public price.
5. ZoomInfo
A large contact database paired with Bombora powered intent scores. If you already live in ZoomInfo for data, the intent add on is a natural extension. It is account level, United States heavy, and demo priced, so it fits a funded sales org more than a solo founder.
6. LinkedIn Sales Navigator
Not marketed as a buying signals tool, but it quietly is one. It surfaces job changes in your saved lists, flags accounts with growth, and lets you build alerts around the people you track. Job changes are one of the most reliable person level signals there is: new role, new priorities, and about 90 days to prove they can change things. Pricing is published per seat on the LinkedIn Sales Navigator page. You still have to check and act on the alerts by hand.
7. Trigify
A newer tool that watches LinkedIn engagement (likes, comments, posts around your keywords) and turns it into lists. Same idea as tracking who interacts with your content or a competitor's, packaged and automated. It is person level and publishes a price. It reads and scores the signal; the outreach still happens in a separate tool.
Best AI tools for buyer intent analysis
"Best AI tools for buyer intent analysis" usually means one of two jobs. The first is scoring: an AI model reads a raw signal and decides whether the person actually fits your ideal customer, so you are not messaging every profile viewer. The second is prioritization: ranking a long account list by how many signals stacked up this week. 6sense leans hard into the second with its predictive model. Sendable uses the first, scoring each profile against the ideal customer you describe before anyone gets contacted. Be skeptical of any tool that promises AI will find perfect leads with no input from you: the model is only as good as the ideal customer definition you give it.
Where these tools fall short for founders
Most buying signals software was built for a marketing team, not a founder. Three gaps show up again and again.
The signal is account level, so it tells you a company is in market but not who to message. The delivery stops at a dashboard, so you get a daily list you never work. And the price is a demo call, which usually means a five figure annual contract. If you are doing your own outreach, look for the opposite on all three: a person level signal, a path straight into a sequence, and a number you can read on the site. For a full breakdown of the account level players and what they cost, I compared them in intent data providers, and the definitional side lives in intent signals.
FAQ
What is a buying signals tool? A buying signals tool watches public actions that suggest someone may buy soon, like a job posting, a pricing page visit, or a research spike on a review site, and puts those people or accounts in front of you. Some stop at reporting the signal; others push it into outreach.
What is the best buying signals software for a small B2B team? Pick a tool that works at the person level, publishes its price, and delivers the signal into a sequence rather than a dashboard. Account level platforms like Bombora and 6sense are built for funded marketing teams, not founders running their own outbound.
Are buying signals the same as intent data? Not quite. Intent data is usually aggregated, third party, account level research data. Buying signals are individual public actions you can see and name in your first message. A buying signals tool that operates at the person level tends to be more actionable for a small team.
What are the best AI tools for buyer intent analysis? The useful ones use AI for scoring (does this person fit your ideal customer?) and prioritization (which accounts heated up this week?). The AI is only as good as the ideal customer definition you feed it, so treat any "no input needed" promise with caution.
