Adapt.io vs SphereScout: Honest Comparison (2026)
Adapt.io and SphereScout solve completely different problems. One sells named decision-maker contacts. The other sells local business inboxes in bulk. We've tested both, and the pricing math alone tells a story that most comparison pages skip entirely. Let's break it down.
30-Second Verdict
SphereScout wins if you need high-volume local business contact lists - restaurants, agencies, contractors - at $1-$3 per 1,000 contacts.
Adapt.io wins if you need person-level B2B contacts with job titles for mid-market or enterprise outreach.
Skip both if you need verified decision-maker emails and direct dials with weekly-fresh data and no credit caps. That's where Prospeo fits - 98% email accuracy, 125M+ verified mobiles, self-serve from day one.
What Each Platform Actually Does
SphereScout is a local business email list provider. It pulls from Google Business Profiles and similar public listings, covering 200M+ local business leads currently focused on the US and France, with more countries being added. You get company-level records: business name, generic email (think contact@ or info@), phone, address, socials. No individual names. No job titles.
Adapt.io is a person-level B2B sales intelligence platform with 150M+ contacts across 30M companies. Individual names, job titles, company data, enrichment credits - built for outbound teams targeting specific decision-makers, not local storefronts.
Pricing Math Side by Side
Here's the thing: these tools shouldn't even be compared on price because you're buying fundamentally different products. But since people search for this, let's lay it out.
SphereScout Plans:
| Starter | Growth | Scale | |
|---|---|---|---|
| Price | $49/mo | $99/mo | $499/mo |
| Contacts | 15,000 | 50,000 | 500,000 |
| $/1K contacts | $3.27 | $1.98 | $1.00 |
SphereScout also offers one-time purchases with no subscription required - a genuine differentiator for teams running occasional campaigns.
Adapt.io Plans:
| Free | Starter | Basic | |
|---|---|---|---|
| Price | $0 | $49/mo | $99/mo |
| Credits/mo | 25 | 500 | 1,000 |
| Daily cap | 25 | 50 | 100 |
| $/1K contacts | - | $98 | $99 |
Annual billing saves roughly 20% on Adapt. Custom plans unlock API access.
At $49/mo, SphereScout gives you 15,000 contacts. Adapt gives you 500. That's a 30x volume difference at the same price point. But SphereScout contacts are generic business emails while Adapt's are named individuals with titles. Apples to oranges.
SphereScout gives you info@ emails. Adapt.io caps you at 100 lookups per day. Prospeo gives you 300M+ named decision-maker contacts with 98% verified email accuracy, 125M+ direct dials, and zero daily caps - all refreshed every 7 days, not monthly.
Stop choosing between volume and accuracy. Get both at $0.01/email.
Data Quality Breakdown
SphereScout: Company name, generic email, phone, city, postal code, socials. Often info@ or contact@ addresses with monthly data refresh. Good for local SMB outreach where you're emailing the business, not a specific person.
Adapt: Person-level records with name, title, company, email, and phone across global B2B coverage. Email accuracy is a known weak spot - G2 reviewers cite incorrect email addresses 14 times in the cons section. In our experience, generic info@ emails convert at a fraction of the rate of named contacts, but only if those named contacts actually land in the inbox. Verify before you sequence, regardless of which tool you use.
Filters, Integrations & Workflow
SphereScout filters by ratings, review count, open/closed status, and email availability. No radius targeting, no native CRM integrations. It's CSV/Excel export-first.
Adapt integrates with Salesforce, Microsoft Outlook, and Slack. The Chrome extension works on company websites and professional profile pages for quick lookups - a real workflow advantage over SphereScout's batch-export model. API access is locked behind the Custom plan, which is frustrating if you're trying to build any kind of automated pipeline.
Social Proof & Reviews
Adapt.io holds a 4.6/5 on G2 from 2,789 reviews - a real sample size. Credit limitations are the #1 complaint with 34 mentions. SphereScout sits at 5.0/5 on G2 from one review and 4.0/5 on Trustpilot.
A perfect G2 score from one review tells you nothing. Reddit discussion is sparse for both tools, so there isn't much community signal to lean on. Based on third-party evidence alone, Adapt is the safer operational bet.
Best Choice by Scenario
Local SMB outreach at scale - You're an agency emailing 50,000 restaurants or contractors monthly. SphereScout at $99/mo gets you there.
B2B decision-maker targeting - You need the VP of Engineering at a Series B SaaS company. Adapt.io gives you the name, title, and email.
Verified emails + mobiles, no credit caps - Neither tool fits cleanly. Prospeo covers 300M+ profiles with 98% email accuracy and a 7-day refresh cycle. B2B data decays 30-70% per year, so that refresh cadence matters more than most teams realize. No daily caps, no contracts, free tier to test.
Adapt's top G2 complaint is credit limits. SphereScout doesn't even give you named contacts. Prospeo delivers person-level B2B data - name, title, verified email, direct mobile - across 300M+ profiles with no daily caps and no contracts. 75 free emails to prove it.
Test 98% email accuracy on your next outreach list - no card required.
FAQ
Is SphereScout a direct competitor to Adapt.io?
No. SphereScout pulls company-level contacts from Google Business Profiles - generic emails like info@ and contact@. Adapt.io is a person-level B2B intelligence platform with named contacts and job titles. They serve fundamentally different outreach motions.
Why does Adapt.io get complaints about credits?
Plans cap both monthly credits (25-1,000) and daily contacts (25-100). Scaling teams hit limits fast - "limited credits" is the top G2 complaint with 34 mentions. If your team does 200+ lookups per day, you'll need the Custom plan or a self-serve alternative without daily caps.
Can I use both tools together?
Yes, and it's a smart play. Pull local business lists from SphereScout, then use a person-level tool to find named contacts at those businesses. Run everything through email verification before sequencing - bounce rates above 5% damage sender reputation fast, and recovering from that is painful.
