SignalHire vs Soleadify: They Don't Actually Compete
Outdated contact info costs B2B sales teams at least one major deal per quarter - that's the stat 73% of teams report. So when you're weighing SignalHire against Soleadify, the stakes feel real. But here's the thing: these two tools solve fundamentally different problems. Picking between them is like choosing between a phone book and a business directory. You probably need both, or neither.
30-Second Verdict
SignalHire is a contact finder. It reveals emails and phone numbers from professional profiles and websites through its browser extension and database. Soleadify is an SMB company-data platform. It gives you firmographics, technologies used, and business categories for small businesses worldwide.
- Need emails and direct dials from professional profiles and websites? SignalHire.
- Need SMB company data for targeting and segmentation? Soleadify.
- Need verified contact data with high accuracy for outbound? Prospeo.

SignalHire: Contact Finder with Credit Limits
We've tested SignalHire side by side with other contact finders, and the browser extension is genuinely easy to use - 12 G2 reviewers call out ease of use as the top strength. Pricing runs $69/mo for email-only credits, $49/mo for phone-only, or $139/mo for the combo plan. Annual billing drops those to $57, $39, and $110 respectively.
The problem is that SignalHire can feel expensive if you're doing light prospecting and don't want to burn credits on misses. The top G2 complaints tell the story: expensive (5 reviews), limited credits (5), and outdated contact info (3). On Trustpilot, billing complaints are brutal - users describe continued charges after cancellation and refused refunds. A 3.8/5 across 73 Trustpilot reviews is mediocre for this category. And "successful lookup" doesn't mean "accurate data," which is a distinction that matters when you're paying per credit.
Skip SignalHire if your team does fewer than 50 lookups a month. The free tier's 5-10 credits won't get you anywhere meaningful, and the paid plans start to sting fast if your hit rate is low.
Soleadify: Best SMB Company Data at This Price
Soleadify takes a completely different approach. Instead of finding contacts, it maps the SMB landscape - 70M+ company profiles across 100+ locations with 40+ data points per record. Business categories, technologies used, digital presence scoring, company size, and publicly available contact info, all refreshed weekly from 10M+ sources. At $99/user/mo with a no-credit-card free trial, nothing else covers this many SMBs at this price point.
For API-heavy workflows, Soleadify also offers pay-as-you-go access through Datarade starting at $2.50/record. That's useful if you're pulling bulk company data into a warehouse or enrichment pipeline without needing the full UI.
Don't expect it to replace a dedicated email finder, though. Soleadify collects publicly available emails as part of company profiles, but Capterra reviewers noted the email add-on was incomplete. And that 5.0/5 G2 rating? It's based on just 2 reviews. One reviewer's main complaint: slow feature development. Neither tool has significant Reddit discussion either, which limits independent validation beyond review sites.
Which Should You Actually Pick?
The question isn't "SignalHire or Soleadify?" It's "Do I need contact data or company data?" Answer that, and the tool picks itself.
Many teams need both: build your target account list in Soleadify, then find decision-maker contacts with a separate tool. That's a perfectly valid workflow, and it's how a lot of outbound teams at agencies we've spoken with actually operate.
Let's be honest, though - for outbound sales teams, neither tool is sufficient on its own. Soleadify gives you the targeting layer but no verified contacts. SignalHire gives you contacts but can waste credits on bad data. The strongest workflow pairs company intelligence from one tool with verified contacts from another.
If your bounce rate is above 5%, data quality is the first thing to fix. Prospeo covers 300M+ professional profiles with 98% email accuracy and 125M+ verified mobile numbers. We've seen the difference a 7-day refresh cycle makes firsthand: Meritt saw bounce rates drop from 35% to under 4% after switching, and their pipeline tripled from $100K to $300K per week.
Bounce rates above 5% kill deliverability and deals. Meritt cut theirs from 35% to under 4% with Prospeo and tripled pipeline to $300K/week. Our 5-step verification and 7-day data refresh mean you reach real buyers, not dead inboxes.

Can I use SignalHire and Soleadify together?
Yes - they serve different purposes and pair well. Use Soleadify to build a target company list with firmographic filters, then use a contact finder to get decision-maker emails and phone numbers at those companies.
