Best LeadBoost Alternatives for Data Enrichment in 2026
At least three different products call themselves "LeadBoost." You've probably already discovered this the hard way - a LinkedIn automation Chrome extension at $19/month, an ActivEngage tool for car dealerships, and a credit-based data enrichment platform built for Agent CRM and HighLevel users. We're talking about the enrichment platform here, and the best alternatives for teams that need more from their data.
Top Picks at a Glance
- Prospeo - Verified B2B emails and direct dials at ~$0.01/lead. Free tier, no contracts, 98% email accuracy across 300M+ profiles.
- Cognism - DNC compliance across 15+ countries baked in. Enterprise-grade data with phone-verified mobiles.
- Clay - Flexible, multi-source enrichment workflows via API and middleware. Great for HighLevel users who like building things.
What LeadBoost Actually Does
LeadBoost enriches CRM contacts by pulling from public records and verified data sources. Each enriched lead costs 5 credits - roughly $0.25 per record. The enriched attributes skew consumer: age range, estimated income, household size, social profiles, military status, auto loan and mortgage presence, even retirement account indicators. It integrates tightly with Agent CRM via a pre-built workflow and offers real-time DNC checks with CRM tagging.
No subscriptions, no minimums - just buy credits and go.
Here's the thing: if you need professional B2B contact data (verified work emails, direct dials, company firmographics), LeadBoost's enrichment attributes won't get you there. That's the gap these alternatives fill.
Best LeadBoost Alternatives Compared
Prospeo
Best for: Teams that need verified B2B emails and direct dials at a fraction of LeadBoost's per-record cost.
Prospeo covers 300M+ professional profiles with 98% email accuracy and a 7-day data refresh cycle - while the industry average sits around six weeks. The enrichment engine returns 50+ data points per contact with a 92% API match rate, and it pushes directly into Salesforce, HubSpot, Lemlist, Instantly, or any stack via Zapier and Make. That refresh cadence matters more than most people realize, because B2B contact data decays roughly 30% per year, and stale records quietly wreck deliverability before anyone notices.
Let's talk cost. At $0.25/record, enriching 10,000 leads on LeadBoost runs $2,500. On Prospeo, enriching 10,000 B2B emails costs roughly $100 at ~$0.01/email. We've tested dozens of enrichment tools, and that per-record gap is the widest we've seen. The free tier gives you 75 verified emails and 100 Chrome extension credits every month - enough to test before committing a dollar.
One scenario we see constantly: an outbound agency scales a client campaign to 50K contacts, burns through credits on a tool with mediocre accuracy, then spends weeks cleaning up bounce damage. Prospeo's 5-step verification with catch-all handling, spam-trap removal, and honeypot filtering exists specifically to prevent that spiral. Stack Optimize, for instance, built from $0 to $1M ARR while keeping client deliverability above 94% and bounces under 3%.
Skip if: You specifically need consumer demographic data like household size, income estimates, or mortgage status. Prospeo focuses on professional contact data - work emails, direct dials, company intelligence - not consumer attributes.
Cognism
Cognism screens against do-not-call lists in 15+ countries natively. That's the main reason enterprise teams pay the premium. The database includes phone-verified mobile numbers, and their GDPR compliance goes deeper than most competitors, with enterprise-grade privacy workflows and built-in DNC screening across supported markets.
| Pros | Cons |
|---|---|
| DNC scrubbing in 15+ countries, built in | 5-user Grow plan starts ~$22,500/year; Elevate at $37,500+ |
| Phone-verified mobile numbers | Budget $500-$1,500 for onboarding |
| Strongest EMEA data quality in this category | Expect 10-15% annual renewal increases |
| Case studies show 98% match rate vs 72% for legacy providers | US database depth still trails ZoomInfo |
Skip if: Your budget is under $20K/year or you don't sell into regulated industries across multiple countries. The ROI math simply doesn't work for smaller teams.
Clay
Best for: HighLevel users who want to build custom enrichment workflows pulling from multiple data sources.
Clay takes a middleware approach - push contacts from HighLevel via API, enrich them through Clay's waterfall of data providers, then map the fields back into your CRM. It's powerful but requires setup. You're building enrichment logic, not clicking a button.
Free tier available, paid plans typically start around $149/month. The credit system varies by data source, so costs depend on which providers you chain together. The consensus on r/sales and r/outbound is that Clay is incredible once configured but has a real learning curve - plan for a few hours of setup before anything flows smoothly. For teams comfortable with no-code automation, nothing else on this list matches its flexibility. If you want a deeper breakdown of workflows and cost math, see Clay list building.
Skip if: You want a simple tool that works out of the box without configuration.
ZoomInfo
ZoomInfo's database covers 321M active professionals at 104M companies. It's the benchmark everyone measures against - and the price tag reflects it.
Professional plans start at $15,000-$18,000/year for 1-3 seats. Advanced runs $22,000-$28,000. Elite hits $35,000-$45,000+. All annual, no monthly option. Watch for credit overages and 10-20% renewal bumps. If your average deal size is under five figures, you almost certainly don't need ZoomInfo-level infrastructure. You're paying for intent data, org charts, and workflow automation that most SMBs and agencies never touch.

Kaspr
Kaspr offers a free plan and paid tiers starting at $49/user/month. A solid pick for individual reps who need quick phone numbers and emails without enterprise overhead or long-term contracts. It won't replace a full enrichment platform, but for solo prospecting it gets the job done.
Breeze Intelligence
Formerly Clearbit, now Breeze Intelligence inside HubSpot. Credit packs range from $30 to $700/month, but credits expire monthly with no rollover - a painful gotcha for teams with variable enrichment volumes. Skip if you're not already on HubSpot. If you’re evaluating vendors broadly, compare options in our roundup of data enrichment services.
LeadBoost charges $0.25/record. Prospeo charges ~$0.01/email - with 98% accuracy, 50+ data points per contact, and a 92% API match rate. That's 25x cheaper enrichment with data that refreshes every 7 days, not every 6 weeks.

Pricing Comparison
Enrichment tools generally use one of five pricing models: pay-as-you-go credits, monthly credits, per-seat, flat fee, or enterprise custom quotes. Enterprise platforms typically land between $12,000 and $80,000 annually. The real cost isn't just per-record price - it's how often you need to re-enrich as data decays. If you’re building a full outbound stack, it helps to map enrichment into your broader lead generation workflow.
| Tool | Starting Price | Per-Record Cost | Contract | DNC Check |
|---|---|---|---|---|
| LeadBoost | Pay-as-you-go | $0.25/record | None | Yes |
| Prospeo | Free (75 emails/mo) | ~$0.01/email | None | No |
| Cognism | ~$22,500/yr (5 users) | Included (fair-use) | Annual | Yes (15+ countries) |
| Clay | Free; ~$149/mo paid | Varies by source | Monthly | No |
| ZoomInfo | ~$15,000/yr | ~$1/lead (est.) | Annual | No |
| Kaspr | Free; $49/user/mo | Included in plan | Monthly | No |
| Breeze | $30-$700/mo | ~$0.07-$0.30/credit | Monthly (HubSpot) | No |
Outbound agencies scaling past 10K contacts can't afford bad data. Stack Optimize built to $1M ARR on Prospeo with sub-3% bounce rates and 94%+ deliverability - across every client campaign. No domain flags. No cleanup sprints.
Replace your LeadBoost credits with data that actually protects your domains.
DNC Compliance Matters
If you're calling leads, DNC compliance isn't optional - it's existential. Penalties run up to $43,792 per call for DNC violations and $1,500 per call under TCPA, with class action exposure reaching into the hundreds of millions. In our experience, teams that skip DNC scrubbing regret it within the first quarter. (If you’re also running cold email, pair compliance with a solid email deliverability guide.)
Only Cognism and LeadBoost include built-in DNC screening in this list. For everyone else, pair your enrichment provider with a standalone scrubbing service like DNC.com at $0.001-$0.01 per number depending on volume. CallAction also offers a free CSV audit for DNC-registered numbers if you want to test before committing to a paid service.
