Not all leads deserve equal attention—and your sales team knows it. The challenge is figuring out which prospects are ready to buy versus which ones will ghost after the demo. Lead scoring tools solve this by automatically ranking leads based on behavior, demographics, and engagement signals.
But with dozens of options flooding the market, choosing the right one feels overwhelming. We evaluated the top lead scoring solutions based on AI capabilities, integration depth, ease of setup, and pricing transparency. Whether you're a scrappy startup or an enterprise team processing thousands of leads daily, this comparison will help you find the tool that actually fits your workflow.
1. Orbit AI
Best for: Teams who want lead scoring integrated directly into the form capture experience
Orbit AI is an AI-powered form builder that qualifies and scores leads at the moment they submit, eliminating the gap between capture and evaluation.
Where This Tool Shines
Most lead scoring happens after the fact—someone fills out a form, enters your CRM, and then gets scored hours or days later. Orbit AI flips this model by scoring leads in real-time as they complete your forms, triggering immediate workflows based on qualification level.
The platform combines beautiful, conversion-optimized form design with intelligent lead qualification. Your sales team receives pre-scored leads the moment they're captured, with context about why each prospect qualified at their specific level.
Key Features
AI Lead Qualification: Built-in intelligence analyzes form responses and scores leads automatically without manual rule configuration.
Automated Workflow Triggers: Route high-scoring leads to sales immediately while nurturing lower-priority prospects through marketing sequences.
Native CRM Integrations: Connects seamlessly with HubSpot, Salesforce, and 15+ other platforms to sync scored leads directly into your existing workflow.
Real-Time Scoring: No waiting for batch processing or manual review—leads are qualified instantly as forms are submitted.
Modern Form Experience: Conversion-optimized form designs that create a professional first impression while capturing qualification data.
Best For
High-growth teams who want to eliminate the gap between lead capture and qualification. Particularly valuable if your current process involves manual lead review or delayed scoring that creates bottlenecks in your sales pipeline.
Pricing
Free tier available for teams getting started. Paid plans begin at $29/month with scaling options for higher-volume lead generation.
2. HubSpot Lead Scoring
Best for: Companies already using HubSpot who want native scoring without third-party tools
HubSpot Lead Scoring is the native lead scoring functionality built into HubSpot's Marketing Hub, offering both predictive AI and manual rule-based options.
Where This Tool Shines
If you're already invested in the HubSpot ecosystem, their native lead scoring eliminates integration headaches entirely. The platform offers two approaches: predictive scoring powered by machine learning that analyzes your historical conversion data, and manual scoring where you define custom rules based on specific criteria.
The predictive model continuously learns from your closed-won deals, automatically adjusting scoring factors as your ideal customer profile evolves. This means less maintenance compared to purely rule-based systems that require constant manual updates.
Key Features
Predictive Lead Scoring: Machine learning analyzes patterns in your historical data to predict which leads are most likely to convert.
Custom Score Properties: Create manual scoring rules based on demographic attributes, engagement behaviors, or any data point in your CRM.
Automatic Score Updates: Scores refresh dynamically as contacts engage with your content, visit your website, or update their information.
Marketing Automation Integration: Trigger workflows, send targeted emails, or alert sales reps based on score thresholds.
Unified Platform: No need to sync data between separate tools—everything lives in one system alongside your marketing campaigns and sales activities.
Best For
Companies already using HubSpot Marketing Hub who want sophisticated scoring without adding another vendor to their stack. Best suited for teams with enough historical conversion data to train predictive models effectively.
Pricing
Included in Marketing Hub Professional at $800/month and Enterprise tiers. Not available in lower-tier HubSpot plans.
3. Salesforce Einstein Lead Scoring
Best for: Enterprise Salesforce users who need explainable AI predictions at scale
Salesforce Einstein Lead Scoring is the AI-powered predictive scoring engine built into the Salesforce platform, providing conversion likelihood percentages with transparent reasoning.
Where This Tool Shines
Einstein stands out for its explainable AI approach. Rather than giving you a mysterious score, it shows exactly which factors influenced each lead's rating—whether that's job title, company size, engagement frequency, or specific behaviors. This transparency helps sales teams understand why certain leads rank higher and adjust their approach accordingly.
The system automatically retrains its models as new conversion data flows in, ensuring predictions stay accurate even as your market or product positioning shifts. For enterprise teams processing thousands of leads monthly, this self-improving capability reduces the maintenance burden significantly.
Key Features
Predictive Conversion Likelihood: Assigns percentage-based scores indicating probability that each lead will convert to opportunity or customer.
Explainable AI Insights: Shows which specific factors contributed most to each lead's score, making predictions actionable rather than opaque.
Automatic Model Retraining: Machine learning models continuously improve as they analyze new conversion patterns in your data.
Native Salesforce Integration: Scores appear directly in lead records, reports, and dashboards without external syncing.
Historical Trend Analysis: Track how lead quality changes over time to identify shifts in campaign effectiveness or market conditions.
Best For
Enterprise sales teams already committed to the Salesforce ecosystem who need sophisticated predictive scoring with the transparency to justify sales resource allocation decisions to leadership.
Pricing
Requires Sales Cloud subscription. Einstein features typically add $50 per user per month on top of your base Salesforce plan.
4. Madkudu
Best for: Product-led growth companies scoring both marketing leads and product-qualified leads
Madkudu is a predictive lead scoring platform designed specifically for PLG companies that need to combine traditional lead signals with product usage data.
Where This Tool Shines
Traditional lead scoring focuses on marketing engagement—email opens, content downloads, website visits. Madkudu adds product usage patterns to the equation, identifying which free trial users or freemium customers show buying signals based on how they actually use your product.
This dual-scoring approach separates customer fit (are they the right type of company?) from engagement level (are they actively using the product?). For PLG companies, this distinction is critical because a highly engaged user at a tiny company might not be as valuable as a moderately engaged user at an enterprise account.
Key Features
Combined Behavioral and Firmographic Scoring: Evaluates both who the lead is and what they're doing in your product.
Product Usage Integration: Connects to your product analytics to identify product-qualified leads based on feature adoption and usage intensity.
Data Warehouse Native: Works directly with Segment, Snowflake, and other data platforms without requiring complex ETL processes.
Fit and Engagement Models: Separate scoring dimensions let you prioritize based on either ideal customer profile match or active buying signals.
Real-Time Enrichment: Automatically appends firmographic data to leads for more accurate fit scoring.
Best For
SaaS companies with product-led growth motions who need to score both inbound marketing leads and users already in their product. Particularly valuable for teams managing the transition from free to paid tiers.
Pricing
Custom pricing based on lead volume and data complexity. Typically starts around $1,500/month for mid-market companies.
5. Clearbit Reveal + Scoring
Best for: Teams prioritizing data enrichment and account-based identification alongside scoring
Clearbit is a data enrichment platform that identifies companies visiting your website and enriches lead records with firmographic intelligence used for scoring.
Where This Tool Shines
Clearbit excels at answering "who is this lead?" before you even think about scoring them. The platform identifies anonymous website visitors by IP address, revealing which companies are browsing your site even before they fill out a form. This intelligence feeds into scoring systems to prioritize high-value accounts.
The enrichment capabilities extend beyond basic company data. Clearbit appends technology stack information, employee count changes, funding events, and other signals that indicate buying intent or ideal customer fit. This enriched data makes your scoring models significantly more accurate than systems relying solely on self-reported form data.
Key Features
Real-Time Company Identification: Reveals which companies are visiting your website based on IP address, even for anonymous traffic.
Firmographic Data Enrichment: Automatically appends company size, industry, technology stack, and other attributes to lead records.
CRM Scoring Integration: Enriched data flows into HubSpot, Salesforce, or other CRM systems to power more accurate scoring models.
Ideal Customer Profile Matching: Score leads based on how closely they match your defined ICP across dozens of firmographic dimensions.
Intent Signal Detection: Identify companies showing buying signals like hiring sprees, funding rounds, or technology changes.
Best For
B2B companies with account-based marketing strategies who need rich firmographic data to power their scoring models. Especially valuable for teams targeting specific company profiles or industries.
Pricing
Custom pricing based on lead volume and features selected. Annual contracts typically start around $12,000 for small to mid-market implementations.
6. ActiveCampaign
Best for: Growing businesses wanting accessible scoring bundled with marketing automation
ActiveCampaign is a marketing automation platform that includes contact and deal scoring capabilities designed for small to mid-sized businesses.
Where This Tool Shines
ActiveCampaign makes lead scoring approachable for teams who find enterprise platforms overwhelming. The scoring interface is intuitive—you assign point values to specific actions or attributes, and the system calculates scores automatically. No data science degree required.
What sets ActiveCampaign apart is how tightly scoring integrates with automation. You can trigger email sequences when scores cross thresholds, notify sales reps about hot leads, or segment audiences based on engagement levels. This closed-loop approach means your scoring actually drives action rather than sitting as unused data in your CRM.
Key Features
Contact Scoring: Assign points based on email engagement, website visits, form submissions, or any tracked behavior.
Deal Scoring: Score opportunities in your pipeline to help sales teams prioritize which deals to push forward.
Automation Triggers: Launch workflows automatically when contacts reach specific score thresholds.
Unified Platform: Combines email marketing, CRM, and automation in one system, eliminating the need for multiple tools.
Negative Scoring: Deduct points for disqualifying behaviors like unsubscribing or visiting career pages instead of product pages.
Best For
Small to mid-sized businesses that want marketing automation and lead scoring in one affordable platform. Ideal for teams just starting with lead scoring who need an intuitive interface.
Pricing
Lead scoring is included in the Plus plan starting at $49/month for up to 1,000 contacts, with pricing scaling based on list size.
7. Zoho CRM Lead Scoring
Best for: Budget-conscious teams already using Zoho who want AI assistance without premium pricing
Zoho CRM Lead Scoring is the built-in scoring functionality within Zoho CRM, offering both rule-based scoring and AI-powered predictions through Zia.
Where This Tool Shines
Zoho delivers surprisingly sophisticated scoring capabilities at a fraction of the cost of enterprise alternatives. The Zia AI assistant analyzes your historical conversion patterns and predicts which leads are most likely to close, similar to how Salesforce Einstein works but at a much lower price point.
The platform's flexibility stands out—you can use pure AI predictions, manual rule-based scoring, or a hybrid approach. This adaptability helps teams start simple with basic rules and graduate to AI-powered predictions as they accumulate more conversion data. For companies using the broader Zoho suite, the scoring data flows seamlessly across marketing automation, sales, and customer service tools.
Key Features
Zia AI Predictions: Machine learning analyzes your data to predict conversion likelihood for each lead.
Customizable Scoring Rules: Build manual scoring models based on any field in your CRM, from industry to engagement frequency.
Negative Scoring: Automatically reduce scores for disqualifying behaviors or attributes.
Zoho Suite Integration: Scoring data connects with Zoho Marketing Automation, Desk, and other business applications.
Workflow Automation: Trigger actions like sales alerts or email sequences based on score changes.
Best For
Small to mid-sized businesses looking for enterprise-grade AI scoring without enterprise pricing. Particularly valuable for companies already using Zoho products who want unified data across their business systems.
Pricing
AI-powered scoring through Zia is included in the Enterprise plan starting at $40 per user per month. Basic rule-based scoring is available in lower tiers.
8. Breadcrumbs
Best for: RevOps teams who want transparent, customizable scoring models with visual builders
Breadcrumbs is a revenue acceleration platform focused on transparent, co-dynamic lead scoring that combines fit and activity signals.
Where This Tool Shines
Breadcrumbs addresses a common frustration with lead scoring: the black box problem. Many AI-powered tools generate scores without explaining how they calculated them. Breadcrumbs takes the opposite approach with a visual scoring model builder that shows exactly which factors contribute to each lead's score and how much weight they carry.
The co-dynamic scoring methodology separates leads into fit (do they match your ICP?) and activity (are they showing buying signals?). This two-dimensional view helps sales teams distinguish between great-fit companies who aren't engaged yet versus highly engaged prospects who might not be ideal customers. For RevOps teams, this transparency makes it easier to refine models and justify scoring methodology to stakeholders.
Key Features
Co-Dynamic Scoring: Separate fit and activity dimensions provide nuanced lead prioritization beyond single-number scores.
Visual Model Builder: Drag-and-drop interface shows exactly how each attribute and behavior influences scores.
Transparent Explanations: Every score comes with clear reasoning about which factors contributed most.
RevOps Analytics: Detailed reporting on scoring model performance and conversion rates by score band.
Multi-Platform Integration: Syncs with major CRMs and marketing automation platforms to pull in comprehensive lead data.
Best For
RevOps and sales operations teams who need to build, test, and refine scoring models with full visibility into how they work. Ideal for organizations that have struggled with opaque AI scoring systems.
Pricing
Free tier available for basic scoring needs. Growth plan starts at $400/month with advanced features and higher lead volumes.
9. Infer (Ignite)
Best for: Data-driven enterprises needing custom machine learning models trained on their specific data
Infer is an advanced predictive analytics platform that builds custom machine learning models for lead scoring based on your unique conversion patterns and data.
Where This Tool Shines
Infer operates at a different level than most lead scoring tools. Rather than offering pre-built models or simple rule engines, the platform trains custom machine learning algorithms on your specific historical data. This means the scoring factors and weights are unique to your business, not generic across all customers.
The platform combines behavioral signals from your marketing automation system with profile data from your CRM and external enrichment sources. This comprehensive data approach often reveals non-obvious patterns—like how certain email engagement sequences correlate with enterprise deals, or which job titles at specific company sizes convert at higher rates. For large enterprises with complex sales cycles, these custom insights can significantly outperform one-size-fits-all scoring models.
Key Features
Custom Machine Learning Models: Algorithms trained specifically on your historical conversion data rather than generic industry patterns.
Combined Behavioral and Profile Scoring: Integrates engagement activity with firmographic attributes for comprehensive lead evaluation.
Major Platform Integration: Connects with Salesforce, Marketo, HubSpot, and other enterprise marketing systems.
Model Development Support: Data science team helps optimize and refine models based on your business goals.
Continuous Learning: Models automatically retrain as new conversion data becomes available.
Best For
Enterprise companies with substantial historical lead data and complex sales processes who need scoring models tailored to their specific business. Best suited for organizations processing thousands of leads monthly with dedicated RevOps or data teams.
Pricing
Enterprise pricing with custom quotes based on lead volume and implementation complexity. Contact sales for specific pricing.
Making the Right Choice
The lead scoring landscape offers options for every team size and technical sophistication level. Your choice ultimately depends on where you are in your growth journey and what problem you're really trying to solve.
If you want scoring integrated directly into the lead capture experience, Orbit AI eliminates the gap between form submission and qualification. For teams already committed to HubSpot or Salesforce, their native Einstein scoring delivers sophisticated predictions without adding another vendor. Product-led growth companies should look at Madkudu for its specialized ability to combine product usage signals with traditional marketing engagement.
Budget matters too. ActiveCampaign and Zoho provide accessible entry points for teams just starting with lead scoring, offering intuitive interfaces and reasonable pricing. Mid-market companies often find the sweet spot with platforms like Breadcrumbs that balance transparency with predictive power. Enterprise teams processing massive lead volumes may need the custom model development that Infer provides.
Think about your tech stack integration requirements. If you're enriching leads with firmographic data, Clearbit's scoring capabilities complement that workflow naturally. Companies with data warehouses and sophisticated analytics setups benefit from Madkudu's native data platform connections.
The AI versus rules debate also matters. Predictive AI models work brilliantly when you have substantial historical conversion data to train on—typically hundreds of closed-won deals minimum. If you're earlier stage or in a rapidly changing market, manual rule-based scoring gives you more control to adjust quickly as you learn what actually predicts conversion.
Most importantly, consider how scoring fits into your broader workflow. The best scoring system is the one your team actually uses. If your current process involves manual lead review creating bottlenecks, automated scoring with immediate routing can transform your sales velocity. If your challenge is distinguishing between good-fit and poor-fit leads flooding your pipeline, focus on platforms with strong firmographic scoring capabilities.
