LeadSift Alternatives: What to Use Now That It's Gone
Go to leadsift.com right now and you'll get a DreamHost "Site Not Found" page. If your intent data workflow just lost its backbone, you're not alone - but most "alternatives" lists out there recommend CRMs and form builders, not actual intent data tools. That's useless.
Here are the replacements that do what LeadSift actually did, sorted by budget and use case.
LeadSift Is Dead - Here's What Happened
LeadSift was acquired by Foundry (formerly IDG) in December 2021. By October 2022, Foundry had merged LeadSift's technology with KickFire into Foundry Intent, combining their data capture tech and machine learning into a knowledge graph covering 300 million profiles.
Then Foundry itself changed hands. Blackstone-owned IDG sold Foundry to Regent LP in March 2025. The standalone LeadSift brand is gone: the website is offline, and the product has been fully absorbed into Foundry's intent stack. LeadSift ran $1,500/month flat rate before the acquisition. That's real money for a tool that's now a ghost.
Our Picks (TL;DR)
- Prospeo - Best for verified contact data paired with intent signals. 98% email accuracy, 15,000 Bombora intent topics. Starts free, ~$0.01/lead.
- Cognism - Best for European markets and phone-verified mobiles, with Bombora intent on higher-tier packages. ~$15,000/yr platform fee to start.
- Apollo.io - Best free tier for bootstrapped teams that need a starting point. Free plan available, paid from $49/user/mo.
LeadSift paired intent signals with emails that bounced. Prospeo pairs 15,000 Bombora intent topics with 300M+ profiles verified every 7 days - 98% email accuracy, 125M+ direct dials. Snyk cut bounce rates from 35% to under 5% and grew AE-sourced pipeline 180%.
Start free at $0.01/email - no contracts, no sales calls.
Why People Looked for Replacements
Even before LeadSift disappeared, users had complaints. The Capterra reviews tell a consistent story: high email bounce rates, insufficient contact depth, and integration limitations. Users praised its "set it and forget it" filtering and responsive support - the problems were in the data itself.
The broader intent data category has the same issue. On Reddit, practitioners who've tried 6sense, ZoomInfo, and Bombora describe being "mostly disappointed with the quality of data." The core complaint? Mysterious intent scores with no supporting evidence.
Here's the thing: only about 24% of teams report exceptional ROI from intent data. Three out of four companies buying intent signals aren't getting the value they expected. Intent scores alone are worthless without verified, reachable contacts attached to them. The tools that win pair intent with people you can actually call or email - not company-level scores and a prayer that your team figures out who to reach.
The Best Intent Data Tools to Replace LeadSift
| Tool | Starting Price | Best For |
|---|---|---|
| Prospeo | Free / ~$0.01/email | Verified contacts + intent |
| Cognism | ~$15,000/yr | EU markets + verified mobiles |
| Apollo.io | Free / $49/user/mo | Budget teams, free tier |
| Bombora | ~$25,000/yr | Pure intent data feeds |
| 6sense | ~$35,000/yr | Enterprise ABM |
| ZoomInfo | ~$7,200/yr | Streaming intent add-on |
| G2 Intent | ~$10,000/yr | Review-based intent signals |
Prospeo
LeadSift's fatal flaw was pairing intent signals with contact data that bounced. Prospeo fixes that directly.
The database covers 300M+ professional profiles with 98% email accuracy and 125M+ verified mobile numbers, layered with 15,000 Bombora intent topics. You're not choosing between knowing who's in-market and actually reaching them - you get both. Data refreshes every 7 days, where the industry average sits around 6 weeks. That gap means stale job titles, dead emails, and wasted sequences at most other providers.
The proprietary 5-step verification process includes catch-all handling, spam-trap removal, and honeypot filtering. We've seen the results firsthand: customers like Snyk dropped bounce rates from 35-40% to under 5% and saw AE-sourced pipeline jump 180%. Self-serve pricing starts free (75 emails/month) and scales at roughly $0.01 per email. No annual contracts, no sales calls required. For teams that need direct dials, 125M+ verified mobiles are available at 10 credits per number with a 30% pickup rate across all regions.
If you're trying to reduce bounces, start with email bounce rates and a real email deliverability baseline before you scale volume.
Cognism
Use this if you're selling into Europe and need GDPR-compliant prospecting data with phone-verified mobile numbers. Cognism's Diamond Data program means humans actually call the numbers before they hit your CRM - a real differentiator for EMEA-heavy teams.
Skip this if budget matters. Cognism pricing is quote-based, but typical benchmarks look like this:
- Grow: ~$15,000/year platform fee + ~$1,500 per user/year
- Elevate: ~$25,000/year platform fee + ~$2,500 per user/year (this tier includes Bombora intent)
A 5-person team on Elevate runs roughly $37,500/year. That's a serious commitment before you've sent a single email.
Where Cognism wins over ZoomInfo: EMEA compliance and mobile verification quality. Where ZoomInfo still wins: US database depth. Cognism is the right replacement if your pipeline is European.
Apollo.io
Apollo's the obvious starting point for bootstrapped teams. The free tier gives you access to a large database with basic search and limited exports - enough to validate whether intent-driven outbound works for your ICP before committing budget. Paid plans run $49-$99/user/month with more credits and features.
The tradeoff is data accuracy. Apollo's email verification isn't as tight as dedicated data platforms, and bounce rates run noticeably higher on Apollo-sourced lists, particularly for senior contacts. Great starting point. Not a long-term data backbone.
If you're building outbound from scratch, pair this with a tighter lead generation workflow and a few proven sales prospecting techniques.
Bombora
Bombora is the pure-play intent data provider. It doesn't give you contacts - it gives you company-level signals across 13,000+ topics. You'll need a separate contact database to actually reach the people at those companies.
Pricing starts around $25,000+/year for small businesses and scales past $100,000 for enterprise. Annual contracts only. Budget an extra 15-25% above license cost for implementation and topic configuration. If you want Bombora's intent data without the Bombora price tag, several platforms (including Prospeo and Cognism) license Bombora topics directly into their own products.
6sense
Enterprise ABM platform with AI-driven account identification and intent scoring. Pricing runs $35,000-$150,000+/year. Overkill for any team under 200 people, but it's the category leader for coordinated ABM across sales and marketing at scale. Let's be honest - if you're reading a "LeadSift alternatives" article, 6sense probably isn't your budget range.
ZoomInfo Streaming Intent
ZoomInfo's intent data is an add-on, not a standalone product. Mid-market contracts run $7,200-$36,000/year. If you're already in the ZoomInfo ecosystem, adding streaming intent is straightforward. If you're not, buying ZoomInfo just for intent doesn't make financial sense - you're paying for a full platform to access one feature.
G2 Buyer Intent
G2's intent signals are unique: they're based on actual product research behavior on G2's review platform. Pricing runs $10,000-$87,000+/year. Narrow but powerful if your buyers actively compare software on G2 before purchasing. For most B2B categories outside of SaaS, these signals won't be relevant.
76% of teams see disappointing ROI from intent data because scores don't come with reachable contacts. Prospeo combines Bombora intent with 5-step verified emails and 125M+ mobile numbers at a 30% pickup rate - not company-level signals and a prayer.
Stop paying for intent signals you can't act on.
Social Listening? Wrong Category
Some people searching for LeadSift competitors actually want social monitoring - LeadSift did have social listening roots before pivoting to intent data. If that's you, you're in the wrong article. Look at Brand24 ($149+/mo), Hootsuite, or Mention instead. The tools above are for B2B intent data and verified contact information - a different problem entirely.
FAQ
Is LeadSift still available?
No. LeadSift was acquired by Foundry in December 2021 and merged into Foundry Intent by October 2022. The leadsift.com domain is offline as of 2026, and there's no standalone product to buy.
How much does intent data cost in 2026?
Standalone intent feeds range from ~$25,000/year (Bombora) to $150,000+ (6sense enterprise). Budget-friendly options exist: Prospeo layers Bombora intent into its contact platform starting at ~$0.01/email, and Apollo.io offers a free plan with basic intent signals. The right price depends entirely on whether you need raw company-level signals or verified contacts attached to those signals - the latter is almost always more useful for outbound teams.
