B2B Contact Database + Chrome Extension Adapt.io Review: Is It Still Worth It in 2026?
The India-based affordable contact database. Founded in 2016 in Coimbatore, Adapt.io serves 500+ customers with $2.1M ARR + 4.6/5 across 2,789 G2 reviews. The pitch: 150M+ contacts + 30M companies at $49-99/mo entry pricing - meaningfully cheaper than US-based competitors. The catch: 14 G2 reviewers flag incorrect emails as recurring issue, daily contact limits cap workflow at 100/day on Basic, and 'limited credits' shows up in 34+ reviews - the cheap pricing comes with structural credit constraints.
- You're a solo SDR or small team needing affordable B2B contact data
- You want a working free tier (25 credits/mo permanent) for evaluation
- Your TAM fits the 150M+ contact DB scope (US/EU mid-market)
- You need 95%+ email accuracy (incorrect emails are a recurring complaint)
- You need high daily volume (100/day cap on Basic is restrictive)
- You need responsive customer support (India-based; US-EU teams may face timezone friction)
What is Adapt.io?
Adapt.io is the B2B contact database + LinkedIn Chrome extension with 150M+ contacts, founded in 2016 in Coimbatore, Tamil Nadu, India. With 150M+ contacts and 30M companies in the database and 4.6/5 across 2,789 G2 reviews, Adapt.io has built one of the higher-rated B2B contact data platforms at the affordable mid-market price tier - meaningfully cheaper than US-based competitors (ZoomInfo, Apollo, UpLead) at similar use cases.
The core workflow combines a Chrome extension that pulls verified emails + direct dials from LinkedIn profiles with a web app for filter-based prospecting and ABM list building. Free tier delivers 25 email + 25 enrichment credits/month permanently. Starter ($49/mo annual) adds 500 credits + CSV export + saved search alerts + ABM list building. Basic ($99/mo annual) adds phone numbers + native CRM export to Salesforce, HubSpot, Pipedrive, Zoho, Outreach, Salesgear. Annual billing offers 20% savings.
Adapt.io Plans & Pricing
Prices below from adapt.io/pricing (May 2026). Annual billing offers 20% savings across all paid tiers. Daily contact limits per company apply on Basic and below. Phone number access only on Basic tier ($99/mo annual) and Custom.
| Plan | Price | Best for | Key limits |
|---|---|---|---|
| Free | $0 | Solo testing + light usage | 25 email + 25 enrichment credits/mo, Chrome extension, advanced filters, list building, email support |
| Starter | $49/mo (annual: 20% off) | Solo SDRs | 500 email + 500 enrichment credits/mo, all Free + CSV export + saved search alerts + ABM list building + priority email support |
| Basic | $99/mo (annual: 20% off) | Active SDR teams needing phones | 1,000 email + 100 phone + 1,000 enrichment credits/mo, all Starter + CRM export (Salesforce, HubSpot, Pipedrive, Zoho, Outreach, Salesgear) + contact limits per company + basic reporting |
| Custom | Contact sales | Larger teams + custom needs | Tailored credits, all Basic + suppression lists + job change alerts + department growth tracking + team management + advanced reporting + API access + dedicated account manager + onboarding + chat/call support |
Hidden costs to know about
Daily contact limits per company are the real bottleneck - on the Basic plan, you're capped at 100 contacts per day, which can quickly exhaust monthly allowances for active teams. Phone number access is gated to Basic tier and above - Free and Starter are email-only. Limited credits is a recurring complaint cluster - 34+ reviews mention it across G2. Sales Navigator subscription not included; Custom tier API access requires sales call.
Is Adapt.io fair value?
For solo SDRs and small teams running affordable mid-market US/EU outbound at low-to-moderate volume, Adapt.io Starter at $49/mo annual is competitive - meaningfully cheaper than UpLead ($74/mo annual), ZoomInfo (enterprise-only), or LeadIQ Pro ($150/mo annual). For high-volume teams or sender-reputation-sensitive cold email at scale, the credit caps + accuracy gaps push better fits to Apollo (free + $99/mo Pro Unlimited), Findymail (sub-5% bounce guarantee), or Hunter (transparent pricing + better accuracy). The narrow 'cheap mid-market US/EU contact data' use case is genuinely Adapt.io's sweet spot.
Adapt.io Pros & Cons - Summary That Actually Helps You Decide
Based on 2,789+ verified G2 reviews (4.6/5), 200+ Capterra reviews (4.5/5), 500+ customers globally, and 2026 testing from ProSpeo, Puzzle Inbox and Derrick.
High G2 score (4.6/5 across 2,789 reviews)
The 4.6/5 G2 score across 2,789 reviews is among the higher in the affordable B2B contact data tier - meaningfully better than RocketReach (4.5), Datanyze (4.2), or Lusha (4.4). Operational maturity from 8+ years in market shows in product polish at the budget price tier.
Robust filtering + clean Chrome extension UX
Robust filters target leads by industry, company size, or job title - making prospecting much more efficient than less-filtered competitors. Chrome extension is incredibly user-friendly, allowing users to extract verified emails and direct dials straight from LinkedIn. UX polish is genuinely strong at the $49-99/mo price tier.
Genuinely usable free tier
25 email + 25 enrichment credits/mo permanently free is meaningful for solo evaluation. Combined with full Chrome extension + advanced filters + list building access, the free tier alone delivers more functionality than many $30/mo paid tools at this tier.
150M+ contacts + 30M companies (broad DB)
Adapt's database covers 150M+ contacts and 30M companies - meaningfully larger than Datanyze (48M contacts), competitive with Apollo (275M+) at a fraction of the price. Coverage is strongest for US/EU mid-market and tech.
Incorrect emails recurring complaint (14+ G2 mentions)
Fourteen G2 reviewers flag incorrect emails as a recurring issue. Real-world bounce rates are meaningfully higher than UpLead's 95% accuracy guarantee or Hunter's <3% bounce in independent testing. For deliverability-sensitive cold email at scale, Adapt.io alone is a sender-reputation risk - pair with a verifier (Findymail, Hunter) for production motions.
Daily contact limits cap workflow (100/day on Basic)
Daily contact limits are the real bottleneck - on Basic, you're capped at 100 contacts per day. Active SDR teams hit the cap regularly, forcing campaign delays or upgrade to Custom tier. The daily cap is the structural constraint that pushes serious-volume teams to alternatives without daily limits.
"Limited credits" cluster in 34+ reviews
Beyond daily caps, 'Limited credits' shows up in 34 reviews and 'Credit limitations' appears in 24 more - the structural complaint cluster around credit constraints. Combined with paid-tier-only phone access and email-issue mentions, the credit economics push teams to outgrow Adapt.io faster than the headline pricing suggests.
India-based support (timezone + responsiveness friction for US/EU)
Customer service is India-based; US-EU teams may face timezone delays on support requests. Combined with the credit-related complaint cluster, support friction during quota issues can be meaningful for production workflows. Apollo, Hunter and Findymail (US/EU based) typically deliver faster support response times for Western teams.

The Verdict on Adapt.io
Adapt.io is the right answer for solo SDRs and small teams running affordable mid-market US/EU outbound who want a 150M+ contact database + clean Chrome extension at $49-99/mo annual entry pricing. The 4.6/5 G2 score across 2,789 reviews is among the higher-rated in the affordable B2B contact data tier, the free tier (25 email + 25 enrichment credits/mo permanent) is genuinely usable for evaluation, and the India-based team's pricing flexibility delivers meaningful value vs US-based competitors at similar use cases.
The trade-offs are concrete and limit Adapt.io's fit at higher volume or sender-reputation-sensitive workflows. Incorrect emails are a recurring complaint cluster (14+ G2 mentions) - bounce rates are meaningfully higher than UpLead's 95% accuracy guarantee or Hunter's <3% bounce. Daily contact limits cap workflow at 100/day on Basic - active SDR teams hit the cap regularly. 'Limited credits' shows up in 34+ reviews as the structural complaint pattern. And India-based support creates timezone friction for US/EU teams during quota issues.
For solo SDRs and small teams on tight budgets running mid-market US/EU outbound at low-to-moderate volume, Adapt.io Starter at $49/mo annual is fair value within the affordable contact-data tier. For higher accuracy or volume, Apollo, UpLead or Findymail. For broader DB scope, ZoomInfo or RocketReach. And in all cases, Derrick stays free as the in-Sheet data layer that delivers comparable accuracy + phones + LinkedIn data without daily caps, credit complaints or India-timezone support friction.
