Hey Sid vs RB2B: B2B Visitor Intelligence and Advertising Compared
TL;DR:
RB2B and Hey Sid solve different problems. RB2B is a website visitor tracking tool that identifies the people already visiting your site. Hey Sid is a person-based advertising and outreach engine that reaches and warms target accounts before they visit. If your gap is capturing existing traffic, RB2B fits. If it is reaching the right accounts in the first place, Hey Sid fits. Many teams use both, and this guide shows where each wins.
What RB2B does
RB2B is a website visitor tracking and identity tool. It de-anonymizes the people visiting your website, revealing them at the person level rather than only the company, and pushes those profiles to Slack or your CRM in real time so you can follow up quickly.
Its strengths are clear:
Person-level identification, not just the company name, which is rarer and more actionable.
Real-time alerts to Slack or CRM as people visit.
A free tier, which makes it easy to start with little commitment.
Fast setup, with a simple script on your site.
The important limits: person-level identification is mainly a US capability, coverage depends on the visitor being identifiable, and RB2B only sees people who are already on your site. It captures existing interest. It does not create it or reach people who have never heard of you.
What Hey Sid does
Hey Sid is a person-based advertising and outreach engine for mid-sized B2B companies. It combines Always On advertising to exact target individuals, Authority Builder thought leadership, and Precision Connect outreach into one done-for-you motion aimed at the same decision-makers.
Its role is the opposite side of the funnel from RB2B:
It reaches accounts that are not visiting yet, putting you in front of the right people.
It warms them over time across ads, content, and outreach, so interest builds before a conversation.
It runs as a service, with creative, publishing, and outreach handled for you.
It is built for the Nordics and Europe, on a GDPR-compliant basis.
The trade-off: Hey Sid is not a self-serve tool, it needs a defined ICP and target list, and it is priced for a program rather than a free trial. It creates and warms demand. It does not identify anonymous visitors on your site.
The core difference: capturing demand versus creating it
The cleanest way to compare the two is to ask which part of demand each one handles. RB2B works on demand you already have. Hey Sid works on demand you still need to create.
The Demand Map
Demand stage | The job | Which tool |
|---|---|---|
Create awareness among target accounts | Reach the right people who do not know you yet | Hey Sid |
Warm those accounts over time | Build familiarity before a conversation | Hey Sid |
Some of them visit your site | Show up because they now recognize you | Result of the above |
Identify who visited | Reveal the people already on your site | RB2B |
Follow up on that intent | Act on warm, existing interest | RB2B, then your sales team |
Seen this way, the two are not really competitors. RB2B sits at the capture end and answers "who is already interested." Hey Sid sits at the create end and answers "how do the right people become interested at all." A team with strong site traffic but no way to identify it has a capture problem. A team that few of the right accounts ever visit has a creation problem.
Comparison table
Dimension | Hey Sid | RB2B |
|---|---|---|
Primary job | Reach and warm target accounts | Identify website visitors |
Signal or action | Advertising, content, outreach | Person-level visitor identity |
Who it reaches | Accounts not yet aware of you | People already on your site |
Geography | Nordics and Europe focus | Person-level mainly US |
Channels | LinkedIn, Meta, outreach | Your website plus Slack or CRM |
Model | Done-for-you service | Self-serve tool |
Cost | Program pricing | Free tier plus paid |
Best for | Creating and warming demand | Capturing existing demand |
Is Hey Sid an RB2B alternative?
Not in a like-for-like sense, and it helps to be honest about that. If you specifically want to know who is visiting your website, Hey Sid does not do that job, and RB2B or a similar visitor tracking tool is the right pick.
Hey Sid becomes an RB2B alternative only when you reframe the goal. Many teams reach for a visitor identification tool because they want more of the right people in their pipeline, and they assume identifying site traffic is the way to get there. But if too few of the right accounts visit in the first place, better identification of a thin stream of traffic will not fix the pipeline. In that situation the real fix is upstream: reaching and warming the accounts so more of them show up. That is the problem Hey Sid solves, and why it appears in this comparison at all.
Where RB2B wins
RB2B is the better choice in several real situations, and it would be dishonest to pretend otherwise:
You already have meaningful US website traffic and simply cannot see who it is. RB2B turns that anonymous traffic into named people.
You want to start free. RB2B's free tier is a low-risk way to add visitor intelligence.
You need person-level identity, not just the company. Many visitor tools stop at the company; RB2B goes further.
You want fast, self-serve setup without a program or a service contract.
Your sales team thrives on real-time signals and will follow up the moment someone visits.
If your traffic is healthy and your gap is visibility into it, RB2B may be the higher-return first move, full stop.
Where Hey Sid wins
Hey Sid is the better choice when the bottleneck is earlier in the funnel:
The right accounts are not visiting yet. Hey Sid reaches them with person-level advertising and thought leadership so they become aware and warm.
You want a warmed audience, not just an alert. By the time outreach lands, the account has seen you across channels.
You want it run for you. Creative, publishing, and outreach are handled, which suits lean teams of one to three marketers.
You are in the Nordics or Europe and need a GDPR-compliant basis for person-based advertising.
As supporting evidence, Mercuri International used precise person-based targeting to cut ad spend by 85% while attributing one of its biggest deals in a decade to the program, because reaching the right people mattered more than reaching more people. If your pipeline problem is upstream of your website, see how Hey Sid works or book a demo.
Can you use both?
Yes, and for many teams that is the strongest setup. Hey Sid creates and warms demand, which drives more of the right accounts to your site. RB2B then identifies which of those accounts visited, so your team can follow up on genuinely warm interest. One tool fills the top of the funnel, the other reads the signal at the bottom. Used together, they cover the full path from "the right people do not know us" to "the right people are on our site right now." Neither replaces the other; they close different gaps.
Who should choose Hey Sid as an RB2B alternative?
Choose Hey Sid over a visitor tracking tool when your honest bottleneck is reach, not visibility: too few of your target accounts know you, your site traffic from the right ICP is thin, and you would rather have advertising and outreach run for you than install another tool. Choose RB2B when you already have the traffic and just need to see and act on it. If you are outside the US, note that person-level identification is limited, which shifts the balance further toward creating demand rather than capturing it. For company-level visitor identification tools specifically, our guide to the best Leadfeeder alternatives for B2B covers that category.
Cost and commitment: what you are really buying
Price is where the two look most different, but the honest comparison is about what the money buys, not the number.
RB2B is low-commitment. The free tier and self-serve setup mean you can start quickly and leave just as easily. You are buying visibility into traffic you already have, and the ongoing cost is mostly your team's time to act on the alerts. Its value depends on how much of the right traffic already reaches your site.
Hey Sid is a program, not a free trial. You are buying an outcome, reach and warming and outreach run for you, rather than a tool you operate. That means a higher commitment, program-level pricing, and a defined ICP and target list before it works. The value shows over a 60 to 90 day window, not on day one.
Judging them on price alone misses the point. One is a cheap way to see your traffic; the other is an investment in getting the right accounts to know you. They buy different things.
The most common mistake: buying identification when the gap is reach
A pattern shows up often in our work with B2B teams. Pipeline is thin, so the team adds a visitor identification tool expecting it to fill the funnel. It rarely does, because identification only multiplies the traffic you already have. If the right accounts are not visiting, there is very little to identify.
The quick diagnostic is to look at how much of your site traffic comes from your actual ICP. If that stream is small, the constraint is upstream: the right people do not know you yet, and no identification tool fixes a demand-creation problem. The reverse mistake also happens, where a team with strong ICP traffic keeps investing in awareness when it should first capture the demand already arriving.
The rule is simple: match the tool to the constraint. Identification tools like RB2B pay off when traffic is healthy. Demand creation like Hey Sid pays off when it is not. Diagnose which problem you have before buying either one.
Conclusion and next steps
RB2B and Hey Sid are not rivals so much as two ends of the same funnel. RB2B is a strong, low-cost website visitor tracking tool for capturing demand you already have, and it is the right call when your traffic is healthy and unidentified. Hey Sid is the right call when the right accounts are not showing up yet and you need to create and warm that demand, done for you.

FAQ
Is RB2B or Hey Sid better for B2B?
Neither is better in general; they do different jobs. RB2B identifies the people already on your website, so it is better when you have traffic you cannot see. Hey Sid reaches and warms accounts that are not visiting yet, so it is better when the bottleneck is getting the right people interested in the first place.
Does RB2B work outside the US?
RB2B's person-level identification is mainly a US capability, and coverage elsewhere is more limited or company-level. For teams selling primarily outside the US, that limit is worth testing before relying on it, and it is one reason non-US teams often weigh demand creation over visitor identification.
Is Hey Sid a website visitor tracking tool?
No. Hey Sid does not identify anonymous website visitors. It is a person-based advertising and outreach engine that reaches and warms target accounts. If website visitor tracking is what you need, RB2B or a company-level tool like those in our Leadfeeder alternatives guide is the right category.
Can Hey Sid and RB2B work together?
Yes, and they complement each other well. Hey Sid creates and warms demand, driving more of the right accounts to your site, and RB2B identifies which of them visited so your team can follow up. One creates the interest, the other captures the signal, so together they cover both ends of the funnel.
What is the difference between RB2B and Leadfeeder?
RB2B identifies visitors at the person level, mainly in the US, while Leadfeeder and similar tools typically identify the visiting company rather than the individual. Person-level data is more actionable but more geographically limited. Our Leadfeeder alternatives guide compares the company-level visitor identification tools in more depth.
