Leadzy vs Clearbit
Clearbit was acquired by HubSpot and now lives as Breeze Intelligence — an enrichment layer inside HubSpot. Leadzy is a standalone signal-led prospecting suite. Here is how they compare.
Executive summary
Clearbit was, for a decade, the developer-favorite company/person enrichment API. HubSpot acquired Clearbit in late 2023 and relaunched it as Breeze Intelligence in 2024 — still available as enrichment but increasingly woven into HubSpot's CRM, reverse-IP, and AI features. For HubSpot-centric teams, this consolidation is a win: enrichment, segmentation and engagement live in one place. For teams that are not HubSpot-centric or want a full outbound stack (list sourcing, intent, AI writing), Clearbit no longer covers the full workflow the way some users remember from the standalone era. Leadzy serves a different role: signal-led list sourcing with 62 detectors and AI writing on every paid plan, integrating into HubSpot (or any CRM) rather than being subsumed by it. This page explains when each is the right choice in 2026.
- Clearbit is now HubSpot Breeze Intelligence; core API still available but roadmap is HubSpot-native.
- Leadzy is standalone and integrates with HubSpot, Salesforce, Pipedrive and webhooks.
- For HubSpot-centric teams already paying for Pro/Enterprise, Breeze Intelligence is a natural add-on.
- For teams that want live-web sourcing, intent signals and AI writing outside HubSpot, Leadzy is more complete.
- Pricing: Breeze is HubSpot-add-on priced; Leadzy is $49/mo flat.
Positioning (post-HubSpot)
Since acquisition, Clearbit functionality has been repositioned as Breeze Intelligence inside HubSpot — enrichment, visitor identification, AI-powered data quality. Standalone API access remains but new development favours HubSpot-native surfaces.
Leadzy is CRM-agnostic and integrates into HubSpot via a native app with bi-directional sync and automatic deduplication.
Pricing
Breeze Intelligence pricing is packaged with HubSpot tiers; standalone enrichment is usage-based and scales with volume. Public pricing is less transparent post-acquisition and ties to HubSpot's own plan structure.
Leadzy is $49/mo Starter flat; $149/mo Growth flat for 5 users; custom Scale. Pricing is fully public and unlinked to any CRM tier.
Enrichment depth
Clearbit's enrichment is mature — company firmographics, technographics, person attributes — and remains among the best APIs for inbound form enrichment and visitor deanonymisation.
Leadzy enriches prospects with verified emails, decision-maker data and intent events. For pure API-driven enrichment of inbound leads, Clearbit/Breeze is more mature. For outbound list workflows, Leadzy is a better fit.
Intent & signals
HubSpot Breeze adds intent signals via HubSpot's own ecosystem. Depth is growing but varies by tier.
Leadzy includes 62 detectors on every paid plan — composable for trigger-based segments without tier gates.
Workflow fit
For HubSpot-centric inbound motions with high form volume, reverse-IP needs and data quality concerns, Breeze is built for you.
For outbound teams that want to source triggered lists and push into any CRM, Leadzy is built for you.
The two workflows are complementary more often than they compete.
Verdict
See scenarios below for archetype guidance. Short version: Breeze for HubSpot-native enrichment; Leadzy for outbound sourcing across any CRM.
"Clearbit became HubSpot. That is a great answer if you live in HubSpot, and a different kind of answer if you do not."

Real cost by team size
- Solo founder: Leadzy $49 vs Clearbit Only if already on HubSpot Pro — Breeze requires HubSpot tier investment
- HubSpot Pro team: Leadzy $149 add-on vs Clearbit Breeze bundled — Breeze fits naturally; Leadzy complements
- Non-HubSpot team: Leadzy $149 vs Clearbit Standalone enrichment only — Leadzy fits better outside HubSpot
Leadzy — Pros
- Full outbound workflow: source + enrich + AI write
- 62 intent detectors on every plan, no HubSpot tier dependency
- CRM-agnostic — works with HubSpot, Salesforce, Pipedrive, webhooks
- Public, monthly pricing independent of any CRM tier
Leadzy — Cons

Clearbit — Pros
- Best-in-class enrichment API heritage with broad firmographic + technographic data
- Reverse-IP visitor identification for inbound deanonymisation
- Native HubSpot integration (Breeze) — zero-friction for HubSpot teams
- Strong developer-centric API docs inherited from Clearbit

Who should switch, who should stay
Stay on Clearbit / Breeze if you are HubSpot-centric (Pro or Enterprise), if inbound form enrichment and reverse-IP are core to your motion, or if you have existing Clearbit API integrations worth preserving. Choose Leadzy if you need list sourcing and intent signals (not just enrichment), if you are not on HubSpot or want CRM-agnostic tooling, or if you want outbound workflow — triggered segments, AI writing, autopilot — rather than pure enrichment. The two are often complementary at HubSpot-centric teams: Breeze for inbound enrichment, Leadzy for outbound sourcing upstream.
Real-world scenarios
HubSpot-centric marketing team
Problem: A marketing team at a 100-person B2B SaaS runs inbound via HubSpot and wants form enrichment and visitor identification.
Clearbit: Breeze Intelligence is purpose-built for this and sits natively inside HubSpot workflows.
Leadzy: Leadzy is outbound-focused; enrichment inside HubSpot forms is not its core.
Verdict: Breeze / Clearbit wins for this inbound motion.
Outbound SDR team on Salesforce
Problem: A 10-seat SDR org uses Salesforce, Outreach and wants triggered account lists with AI openers.
Clearbit: Clearbit standalone via API can enrich but does not generate triggered lists or draft emails.
Leadzy: Leadzy builds the triggered segment, drafts first sentences, pushes to Salesforce.
Verdict: Leadzy is the better fit for outbound.
Non-HubSpot early-stage team
Problem: A seed-stage startup uses Pipedrive and does not want to adopt HubSpot just for enrichment.
Clearbit: Clearbit standalone is still available but roadmap tilt toward HubSpot is a concern.
Leadzy: Leadzy integrates natively with Pipedrive and any CRM via webhooks.
Verdict: Leadzy is CRM-agnostic and better-fit.
Developer adding enrichment to a product
Problem: An engineering team wants to enrich registrations in their own SaaS using company + person data.
Clearbit: Clearbit API remains a strong developer choice — mature, well-documented.
Leadzy: Leadzy offers API enrichment but is less API-first than Clearbit's developer heritage.
Verdict: Clearbit wins for pure API enrichment in a product.
Agency running multi-client outbound
Problem: An agency runs outbound for 8 clients across unrelated verticals.
Clearbit: Clearbit / Breeze does not fit the per-client sourcing workflow.
Leadzy: Leadzy workspaces isolate each client; Autopilot keeps lists fresh.
Verdict: Leadzy is the better agency fit.
