Alphie vs RB2B: Names vs Booked Demos

RB2B and Alphie both start from the same fact: the vast majority of potential buyers that visit your website leave without a trace. From there the two products go in opposite directions. RB2B turns the visit into a name you can chase afterwards. Alphie turns the visit into a conversation before the visitor leaves, and if the conversation doesn't happen, it does the chasing itself.

I'm going to argue that for a B2B SaaS company with real inbound traffic, the second is worth more. But RB2B is a good product with a very clear job, and there are teams that should pick it. I'll name them too.

What RB2B does

RB2B is a pixel. You install it, and when a US-based visitor lands on your site, it correlates cookies, device identifiers and IP data, matches the visitor against LinkedIn and other professional databases, and sends a profile to Slack: name, job title, employer, LinkedIn URL, and on the Pro plans -- a business email. RB2B's help center describes the identification as US-only by design; visitors from outside the US are geofenced and not identified at the person level. Company-level identification for non-US traffic comes through a Demandbase partnership.

RB2B's homepage says it identifies "70-80% of your website traffic". Their pricing page breaks that down more carefully: 15-20% person-level coverage on the Free and Starter plans, 35-45% on Pro and Pro+, US contacts only. The remainder of that headline figure is company-level.

From Slack, the profile goes wherever you route it. RB2B lists over 50 integrations, and the ones they lead with on the homepage tell you the intended workflow: Salesforce, HubSpot, Clay, Zapier, Instantly, HeyReach, etc. There's also a filtering layer called Hot Leads that tags visitors matching criteria you set (company revenue, company size, seniority, department, category, geography), plus Hot Pages for flagging visits to high-intent URLs and a domain exclusion list. RB2B's own support article on filtering opens with "As your website traffic grows, so does the volume of visitor data RB2B captures. But not every visitor is a good fit," and then walks you through raising the Hot Leads threshold from one matching criterion to three or more. That's an honest description of what living with the product is like: the pixel finds a lot of people, and you spend time deciding which ones matter.

What RB2B doesn't do is talk to the visitor. There's no chat, no on-site content, no booking, no handoff to a rep while the person is still on the page. The Slack alert arrives in real time, but the only thing a rep can do with it is open another tool and write to the person after the fact. And the writing itself, the sequence in Instantly or the connection request in HeyReach, is your job to set up and run.

What Alphie does

Alphie also installs with a script tag, and it also identifies the visitor. But identification is just the first step.

Within a second of a US visitor landing, Alphie identifies the company behind the visit, enriches it (size, industry, stage, geography), and scores it against your ICP. It then watches behaviour: pages, time on page, scroll depth, where they came from. When a visitor crosses a threshold you've set, say ICP score above 70 and two minutes on the pricing page, an assistant panel slides in on the page, with content picked for that specific visitor. A fintech buyer sees a fintech case study. Someone arriving from a competitor's site sees a comparison table. The AI agent asks qualifying questions and answers the visitor's. If a visitor comes back a week later, Alphie recognises the return and picks up the earlier conversation instead of starting from the greeting.

If the score is high enough, your rep gets a Slack message with the company, the ICP score, the list of pages viewed (it keeps updating while the session lasts) and the transcript so far, plus a button. One click and the rep is in the chat, from Slack, while the visitor is still on the page. The AI announces the handoff, the chat header switches to the rep's name and photo, and once a human has talked to that visitor the AI stays out of their later sessions. If nobody joins, the visitor can book a meeting inside the panel against a live Google Calendar.

If they leave anyway, Alphie finds the people in your buyer roles at that company, writes each of them a personal email sequence, and, if you run LinkedIn outreach, drops the same contacts into your HeyReach or Dripify campaign. You decide whether the emails wait for your approval or go out on their own. Companies already in your CRM can be excluded so you don't cold-email an existing customer.

Alphie's identification is company-level, not person-level. That's a deliberate choice, because company-level identification is several times more accurate, and it's the one area where RB2B does something Alphie doesn't.

Where RB2B wins

Person-level identity in the US. If what you want is the LinkedIn URL of the individual who read your pricing page on Tuesday, RB2B gives you that and Alphie doesn't. Alphie identifies the company; the contacts it then finds (verified email, LinkedIn) are the people in the roles you sell to that company, which is a different thing from telling you who visited.

Price of entry. RB2B has a free plan (150 company-level resolutions a month), and paid plans run $79, $149 and $199 a month. Alphie starts at $759 a month. If you have a small site and want to see who's visiting before you commit to anything, RB2B costs nothing to try.

Setup and footprint. RB2B claims a five-minute setup and says 100,000+ websites use it, with 4.5 stars across 275+ G2 reviews. Alphie is in private beta with pilot customers. If you want the tool everyone else in your Slack community already runs, that's RB2B.

Where Alphie wins

Timing. When RB2B fires, your rep sees a name in Slack and their next move is an email or a LinkedIn message, which the visitor reads later, if at all, next to everyone else's. When Alphie fires, the visitor is on your pricing page, has just been shown a case study from a company their size, and has a rep typing to them within seconds. The Harvard Business Review study on lead response found firms that contacted a lead within an hour were nearly seven times as likely to qualify it as those that waited even an hour longer. Alphie is built around the first sixty seconds, not the first hour.

It acts on the data. RB2B's output is a profile in Slack; everything after that is another tool and someone's time. Alphie's output is the action: the panel opens, the rep is routed in, the meeting gets booked, and if none of that lands, the three-email sequence goes out and the contacts appear in your HeyReach or Dripify campaign. RB2B lists HeyReach as an integration too, but there you're pushing one name into a campaign by hand; Alphie decides which roles at the company to find and pushes them for you. It also runs the loop backwards: if someone from a company already in your HeyReach campaign shows up on the site, you get told, so the outbound you're already running starts feeding the inbound.

Qualification before the alert, not after. RB2B's Hot Leads is a filter on the firehose; you tune thresholds so fewer names reach Slack. Alphie scores every visitor against the ICP first and only opens the panel or pings a rep when the score and the behaviour both clear the bar. The rep's Slack channel gets qualified conversations, not a stream of profiles to triage.

One product instead of a stack. To do what Alphie does with RB2B, you need RB2B, a chat widget, a scheduling tool, an enrichment source, a sequencer, a routing rule somewhere, and a person who watches Slack all day. Each piece has its own vendor, its own billing and its own place the handoff can break. Alphie ships the identification, scoring, on-site engagement, Slack-to-chat handoff, booking, email and LinkedIn follow-up and CRM sync (HubSpot, Attio, Airtable, Salesforce, REST API for others) as one thing.

Pricing that doesn't run out mid-month. RB2B bills per "resolution", with overage at 25-45 cents each once you pass your monthly allowance, and $99 a month for up to five extra domains. Alphie's plans are by unique monthly visitors: under 10,000 on Startup, 10,000 to 50,000 on Pro. There's no per-identification credit to watch.

Side by side

The price gap, argued openly

$759 a month against $199 a month is not a rounding error, so let me say what each number buys.

RB2B's $199 buys you names. Turning names into pipeline is on you: the chat tool, the scheduler, the sequencer, the enrichment credits, and the SDR hours spent triaging Slack. RB2B's own filtering guide exists because that triage is real work.

Alphie's $759 buys the part that happens after identification: the scoring, the panel, the content, the chat, the booking, the handoff, and the emails and LinkedIn touches that go out when the visitor leaves. What it replaces is the gap between a visit and a reply. If your average deal is small enough that a live conversation on the pricing page doesn't move the number, you don't need Alphie. If one extra closed deal a quarter covers $9,108 a year, the arithmetic is short.

What we can and can't claim yet

Alphie is in private beta. We're running pilots with a handful of YC companies, and the target we've set for those pilots is a 30% lift in inbound conversion from the same traffic. That's a floor we're aiming at, not a result we've published. When we have customer numbers we'll put them on this page with names attached. Until then, everything above is about mechanism: what each product does, and when.

RB2B has more customers, more reviews and a lower price. What it doesn't have is a way to talk to the visitor. It tells you who they were; it can't say anything to them.

Who should pick which

Pick RB2B if your team runs an outbound motion and wants the visitor's name as one more signal to feed it, if you need company names for non-US traffic, or if you want to see who's visiting for free before you spend anything.

Pick Alphie if you're a B2B SaaS company with sales-assisted deals and real inbound traffic, and the problem you're trying to solve is that qualified people visit your site and leave without talking to anyone.

The 95% of qualified visitors who don't convert are the same 95% either way. The question is whether you'd rather know their names afterwards, or talk to them while they're there.
