Seamless.AI vs Soleadify: Different Tools for Different Jobs
Seamless.AI finds individual emails and phone numbers for cold outreach. Soleadify catalogs SMB company data for market research and agency targeting. The Seamless.AI vs Soleadify question keeps coming up, but here's the thing - these tools solve fundamentally different problems. Comparing them head-to-head is like comparing a CRM to a spreadsheet. Let's break down what actually matters.
30-Second Verdict
Seamless.AI is for outbound SDRs who need emails and direct dials, one contact at a time. Soleadify is for data teams and agencies who need company-level intelligence on small businesses worldwide. In our testing, these tools barely overlap.

What Seamless.AI Does
Seamless.AI is a real-time contact and company search engine. Type in a job title, company, or industry, and it surfaces emails and phone numbers on the spot. The Chrome extension works across the web, and each contact lookup costs one credit.
User-reported accuracy runs around 85% for emails and 60% for phone numbers - decent for emails, rough for dials. Credits burn fast, too. A widely-cited Reddit thread calls out that you'll chew through your monthly allotment in a single prospecting session if you aren't careful.
The free tier gives you 50 credits. Basic runs around $147/month on annual billing for 250 monthly credits per user. One user reported Pro at $79/user/month with 1,000 credits, Enterprise at $149/user/month with a 5-seat minimum ($745/month floor). Another pricing analysis pegs median annual spend at $7,775 across 40 buyers - which is a lot of money for 85% accuracy.
Skip Seamless.AI if you hate opaque pricing or aggressive sales tactics. Multiple Reddit threads flag repeated unsolicited calls from the sales team, and the consensus on r/sales leans toward trying Apollo first for more transparent pricing.
If you're evaluating tools for outbound, it also helps to map your workflow against modern sales prospecting techniques and the broader category of SDR tools.
Seamless.AI burns credits fast at 85% accuracy. Soleadify doesn't even have a working email add-on. Prospeo delivers 98% verified emails from 300M+ profiles at $0.01 each - with 30+ filters to replace both tools in one platform.
Stop paying more for emails that bounce.
What Soleadify Does
Soleadify is purpose-built for one thing: helping agencies and data teams build company target lists by industry, geography, and tech stack for SMB markets. That's the entire value proposition, and it does it well.
The platform covers 600+ business categories with technographic filtering (WordPress, Shopify, etc.), weekly data updates sourced from 10M+ data sources, digital presence scoring, and DBA/alias tracking. If you're running an agency that sells to local businesses or building market maps for SMB verticals, this is genuinely useful intelligence that's hard to find elsewhere.
The database size claims deserve scrutiny, though. Soleadify's own site says 70M+ company profiles. Capterra's listing says 35M+. G2 says 40M+. That inconsistency erodes trust. And while G2 gives it a perfect 5.0, that rating comes from exactly 2 reviews - not a meaningful sample. One Capterra reviewer specifically noted the "email addon function still not ready," so don't expect individual contact data here.
Pricing starts at $99/user/month for SaaS access. API and dataset access starts at $2.50.
If you're comparing vendors in this category, it's worth grounding the discussion in what "company data" actually includes (see firmographics and firmographic filters), and how it fits into your broader lead generation workflow.
The Real Difference
Look - this comparison shouldn't exist. Soleadify answers "which companies should I target?" Seamless.AI answers "how do I reach the people at those companies?" They're sequential steps in the same workflow, not competing solutions. If you need both, you're looking at two tools or one that bridges the gap.
If your average deal size sits below $10k and you're selling to SMBs, Soleadify's company intelligence paired with a strong contact finder is a better stack than Seamless.AI alone. Seamless.AI's credit model punishes high-volume prospecting at exactly the price point where margins are thinnest.
For teams that need both company and contact coverage, it can help to benchmark against the broader market of sales prospecting databases and B2B company data providers.
A Smarter Stack for 2026
Beyond raw contact data, you get 30+ search filters - buyer intent powered by Bombora across 15,000 topics, technographics, job changes, and headcount growth signals - so you can layer targeting precision on top of Soleadify's company lists. The Chrome extension (40,000+ users) pulls verified emails and phones from any website or CRM in one click. One of our customers, Snyk, cut their bounce rate from 35-40% to under 5% and saw AE-sourced pipeline jump 180% after switching to this kind of verified-first workflow.
If you're trying to keep deliverability clean while scaling outbound, it's also worth understanding email bounce rate and the basics of an email deliverability guide.
Need Soleadify's company targeting and Seamless.AI's contact data in one tool? Prospeo combines buyer intent across 15,000 topics, technographics, and headcount signals with 143M+ verified emails - on a 7-day refresh cycle, no contracts.
One platform. Company intelligence and verified contacts. Zero bounces.
FAQ
Is Soleadify a Seamless.AI competitor?
Not really. Soleadify provides SMB firmographics - business categories, tech stacks, company size. Seamless.AI finds individual emails and phone numbers. They serve different workflows and different buyers, so framing Seamless.AI vs Soleadify as a head-to-head matchup is misleading.
Which tool has better email accuracy?
Seamless.AI runs around 85% email accuracy based on user testing. Soleadify's email add-on isn't functional yet. For verified individual contacts, Prospeo's 98% accuracy across 143M+ addresses is the strongest option - and at $0.01 per email, it's significantly cheaper than Seamless.AI's credit model.
Can I use Soleadify for cold outreach?
Soleadify provides company-level data, not individual contacts. You can identify target companies by industry, location, and tech stack, but you'll need a separate contact finder to actually reach the people at those companies.
What's a good free alternative to both tools?
Prospeo's free tier includes 75 verified emails and 100 Chrome extension credits per month with no credit card required. That's enough to test outbound workflows before committing budget. Seamless.AI's free plan caps at 50 credits, and Soleadify doesn't offer a free tier at all.
