7 Airscale Alternatives for Verified B2B Data in 2026
Thirty to fifty percent of your CRM data is already outdated right now. That stat alone should make you care about which enrichment tool you pick. You found Airscale, liked the $49/mo starting price, and thought the waterfall enrichment pitch sounded solid. Then you went looking for reviews and found nothing you can actually validate at scale: zero G2 reviews, an inactive G2 profile, and no meaningful Reddit discussion. That's when most teams start shopping for alternatives with an actual track record.
Here are seven, sorted by what matters most: data accuracy, pricing transparency, and whether other teams have validated the tool at scale.
Our Picks (TL;DR)
- Prospeo - Best for email accuracy (98%) and verified mobiles. Free tier, no contract.
- FullEnrich - Best enrichment-only waterfall tool. 4.8/5 on G2 with 167 reviews.
- Apollo - Best budget all-in-one if you can tolerate bounce rates north of 30%.
What Airscale Does (and Where It Falls Short)
Use Airscale if you want waterfall enrichment across 30+ data providers with enrichment as low as ~$0.008 per email, plus an AI research agent (Airsearch) that can visit websites and extract custom data points. Pricing runs $49-$189/mo, and credits roll over while your subscription stays active.
Skip Airscale if you need social proof before committing. The 91% phone success rate comes from a single review-cited test that isn't fully documented independently. CRM integration depth beyond HubSpot is limited, there's no multi-step workflow automation, and there's no permanent free plan. For a tool handling your contact data pipeline, that's a lot of trust to extend on faith.
Airscale promises waterfall enrichment but has zero G2 reviews to back it up. Prospeo has 15,000+ companies trusting its 98% accurate emails, 125M+ verified mobiles, and a 7-day data refresh - not six weeks. Free tier included, no contract required.

Best Airscale Alternatives (Ranked)
Prospeo - Best for Accuracy
Prospeo is the pick if data quality is the thing keeping you up at night. The database covers 300M+ professional profiles with 143M+ verified emails and 125M+ verified mobile numbers, all refreshed on a 7-day cycle - the industry average is six weeks, so that weekly refresh catches job changes and role moves other tools miss for over a month.
Email accuracy sits at 98%, backed by a proprietary 5-step verification process that includes catch-all handling, spam-trap removal, and honeypot filtering - the stuff that catches most tools off guard. Meritt dropped their bounce rate from 35% to under 4% after switching, and their pipeline tripled from $100K to $300K per week. You also get 30+ search filters covering buyer intent via 15,000 Bombora topics, technographics, job changes, headcount growth, and more, plus CRM and CSV enrichment that returns 50+ data points per contact.
The Chrome extension has 40,000+ users. Native integrations cover HubSpot, Salesforce, Smartlead, Instantly, Lemlist, Clay, Zapier, and Make. Pricing starts free with 75 emails and 100 extension credits per month, with paid plans available monthly. No contracts, no sales calls required.
FullEnrich - Best Enrichment-Only Waterfall
FullEnrich is the closest direct competitor to Airscale's core value prop: waterfall enrichment querying multiple providers in sequence. It pulls from 20+ data sources and runs triple email verification, keeping bounce rates around 1-2%.
What separates FullEnrich from Airscale is trust. It carries a 4.8/5 on G2 with 167 reviews - compared to Airscale's zero G2 reviews - compared to Airscale's zero. Pricing runs $29/mo for 500 credits up to $1,950/mo for 50,000 credits. One credit per work email, three credits for personal emails, 0.25 credits for person/company lookups, and ten credits per phone number. Credits roll over for three months on monthly plans, one year on annual.
The trade-off: no native CRM integration, no outreach automation, no buying signals. It's enrichment and nothing else - which is exactly what some teams want.
Apollo - Best Budget All-in-One
Let's be honest: Apollo is the best free tool in B2B sales and the most dangerous one. You get sourcing, sequencing, and a lightweight CRM for $0. That's incredible for solo founders who need to start prospecting today.
The danger is deliverability. Reddit practitioners have tested Apollo exports and consistently report bounce rates of 32-38%. We've seen teams burn through credits fast when half their sends bounce. Additional email credits cost $0.20 each and don't roll over. Use Apollo to build lists, but verify every contact externally before you hit send. Paid plans start at ~$49/user/mo.
Zeliq - Free Tier with Sequencing
Zeliq's free plan includes 100 leads/month plus built-in email sequences. The Starter plan runs $59/user/mo for 750 credits, with one credit per email and ten per phone. Credits never expire, which is a real differentiator.
The limitation is scale. Zeliq syncs with HubSpot, Salesforce, and Pipedrive, but database depth doesn't match larger players. Strong for small teams running lean outbound, not for 50-rep sales orgs.
PhantomBuster - Scraping and Automation Engine
PhantomBuster isn't an enrichment database - it's a workflow automation tool. You build scraping sequences yourself, and pricing runs on execution time: $69-$439/mo for 20-300 hours/month. It's workspace-based, supporting up to 100 accounts, and integrates with HubSpot, Salesforce, Clay, Zapier, and Make.
If your workflow is automation-first and you'll handle verification separately, PhantomBuster is hard to beat. If you want plug-and-play enrichment, look elsewhere.
Cognism - Enterprise-Grade Data
Cognism offers phone-verified mobile numbers, and the EMEA coverage is strong. But the pricing reflects enterprise positioning: expect ~$15K-$25K/year in platform fees plus $1,500-$2,500/user/year, with enterprise contracts running $30K-$100K+. Overkill for teams under 20 reps.
Amplemarket - All-in-One for Funded Teams
Amplemarket bundles AI sequencing and enrichment into one platform. The Startup plan runs $600/mo on an annual term with two users included. Growth and Elite tiers are custom-priced - expect $1,000-$2,500/mo based on team size. It's a capable tool if you've got the budget, but that $7,200/year starting point puts it out of reach for most early-stage teams.
Pricing Comparison
Three tools offer permanent free tiers: Prospeo, Apollo, and Zeliq. The rest require a paid plan after a trial or sales process.
| Tool | Starting Price | ~Cost/Email | ~Cost/Phone | Best For |
|---|---|---|---|---|
| FullEnrich | $29/mo | ~$0.06 | ~$0.58 | Enrichment-only |
| Apollo | Free | ~$0.20 | Varies | Budget all-in-one |
| Zeliq | Free | ~$0.08 | ~$0.79 | Free sequencing |
| PhantomBuster | $69/mo | ~$0.14 | N/A | Automation |
| Cognism | ~$15K/yr | Custom | Custom | Enterprise EMEA |
| Amplemarket | $600/mo | Custom | Custom | Funded teams |
| Airscale | $49/mo | ~$0.008 | ~$0.15 | Unproven waterfall |
How to Choose
Here's the thing: Airscale might be fine. But you can't verify that without independent reviews, and your domain reputation isn't something to gamble with.
Pick Prospeo if you need verified accuracy and a free tier to test first. Best for teams where bounce rates directly impact domain reputation - and in our experience, that's every outbound team.
Pick FullEnrich if you want enrichment-only waterfall with proven G2 reviews and don't need outreach built in.
Pick Apollo if you're bootstrapped and need an all-in-one today - just verify emails before sending.
For teams that run automation-heavy workflows and handle verification separately, PhantomBuster fills a different niche entirely. And if you're at the enterprise level with 20+ reps and strong EMEA needs, Cognism or Amplemarket are worth the conversation.
At ~$0.01 per email, Prospeo costs less than Airscale's cheapest plan while delivering 98% accuracy, 30+ search filters with Bombora intent data, and CRM enrichment returning 50+ data points per contact. Meritt tripled their pipeline after switching.
Replace unverified enrichment with data that actually connects you to buyers.
FAQ
Is Airscale's data actually accurate?
Airscale cites a 91% phone success rate from a single review-cited test, but zero G2 reviews validate this at scale. A safer approach: choose a tool with independently validated performance, or run a 200-500 contact pilot and measure bounce and connect rates before migrating your pipeline.
Do Airscale alternatives use waterfall enrichment?
Some do. Waterfall enrichment queries multiple data providers in sequence and returns the first verified match per contact. FullEnrich is built around this model, while other tools focus on proprietary databases plus verification. If you're optimizing for deliverability, prioritize verification quality and refresh cadence over the raw number of upstream sources.
Which Airscale alternative has the best free tier?
Prospeo is the strongest free option for teams that care about deliverability: 75 verified emails plus 100 Chrome extension credits per month with no contract. Zeliq includes 100 leads/month with sequencing, and Apollo has a free tier too - but you should budget time or another tool for verification given the bounce rate issues we've seen reported.
Summary
If you're comparing Airscale alternatives, the real decision is whether you want "waterfall across providers" or "verified accuracy with fast refresh and clean enrichment." For most outbound teams, Prospeo is the best starting point because you can test it free, keep bounce rates under control, and scale into CRM enrichment and intent filters without signing an annual contract.
