What is LeadSpyder?

LeadSpyder identifies the people visiting your website (person-level), with name, email and phone where available, delivered to your CRM. On average, LeadSpyder identifies 30% or more of non-bot, U.S.-based website traffic. Results vary by site. It matches against a 269M+ U.S. consumer profile identity graph with up to 27 data points.

Where RB2B and Warmly are built for B2B revenue teams, LeadSpyder covers both: B2B visitors with company, job title and LinkedIn profile where available, and consumers for local and service businesses, in one platform. It goes past the data:

1. Identify the people.
2. Rank them with SpyderScore (0 to 100 by intent) and alert the team with SpyderAlert, delivered to the CRM.
3. Start the conversation with a helpful, value-first email on every plan.
4. On Starter Pro + AI Employee, the AI Employee answers replies across calls, website chat, DMs and texts, qualifies the person and books the appointment.

Pricing is public: $1 for 7 days (up to 50 identified visitors), then Starter $200/mo (600 identified visitors), Starter Pro $500/mo (1,500) or Starter Pro + AI Employee $1,000/mo (3,000). Annual billing equals 10 months' price, which works out to $0.33 per identified visitor at full volume. No setup fees, no contracts, cancel anytime. See pricing and how it works.

Warmly vs RB2B: what are the real differences?

Price and commitment

This is the biggest gap. RB2B lets a single rep start free and move to $79 or $149 a month. Warmly's lowest published plan is $10,000 a year, or $4,875 a quarter. If you are a small team testing visitor identification, RB2B is the lower-risk start. If you have a revenue team and budget for an annual platform, Warmly offers more automation.

What you get per visitor

RB2B's Starter plan delivers LinkedIn profile URLs, not email addresses. Business emails start on Pro. Warmly's entry plan identifies contacts and companies and syncs them to your CRM, with routing and retargeting. Check exactly which fields you need before choosing a tier.

Automation

RB2B is a data delivery tool: it finds the visitor and sends the result where your team works. Warmly adds website chat and AI agents that can engage visitors and follow up on its higher plans.

Ownership

Warmly has agreed to be acquired by HubSpot. Warmly says existing contracts and pricing are unchanged for now. If you are signing a long contract, ask how the product will evolve inside HubSpot.

What are the best RB2B alternatives?

People look for RB2B alternatives for three common reasons: they need emails and phones without stacking tiers, they sell to consumers or local customers rather than businesses, or they want help turning names into conversations.

• LeadSpyder if you sell to people in the U.S. and want identification, ranking, a helpful first email and (on the top plan) an AI Employee. Full comparison: LeadSpyder vs RB2B.
• Warmly if you are a B2B team that wants chat and AI agents and can sign an annual or quarterly contract.
• A company-level tool such as Leadfeeder if much of your traffic is outside the U.S. See LeadSpyder vs Leadfeeder.

What are the best Warmly alternatives?

The most common reason to look past Warmly is the starting price. Alternatives:

• RB2B for a low-cost, self-serve B2B option with a free company-level tier.
• LeadSpyder for person-level identification with public monthly pricing, no contracts, and an AI Employee that answers replies across calls, chat, DMs and texts on the $1,000/mo plan. Full comparison: LeadSpyder vs Warmly.
• HubSpot's own tools if you are already a HubSpot customer and want to wait and see how Warmly is folded in.

Who is each tool best for?

Choose RB2B if

• You sell B2B, most of your traffic is in the U.S., and your reps work in Slack and LinkedIn.
• You want to start free or at a low monthly price and grow into higher tiers.
• Your team is comfortable doing its own research and outreach.

Choose Warmly if

• You run a funded B2B revenue team and want identification, chat and AI agents in one platform.
• You can commit to an annual or quarterly contract starting at $10,000 a year.
• You use HubSpot and like the direction of the acquisition.

Choose LeadSpyder if

• You sell to people in the U.S.: homeowners, patients, clients or small business owners. Think roofing, HVAC, dental, med spa, mortgage, insurance, real estate or legal.
• You want each identified visitor ranked, your team alerted, and a helpful first email started for you.
• You want replies answered and appointments booked without hiring more staff.
• You prefer public pricing, no setup fees and no contracts.

How should you follow up with an identified visitor?

The same rules apply whichever tool you pick:

1. Consent first. LeadSpyder's pixel uses a first-party cookie and asks for consent first where state law requires it.
2. Email first, about the topic. Send something useful about what the person was researching. Never mention the visit.
3. Calls and texts after engagement. Only after the person replies, fills in a form or calls you.
4. Measure outcomes. Replies, booked meetings and revenue matter more than the number of names.
