# Adapt.io Review: Is It Still Worth It in 2026?

Adapt.io is a B2B contact database with a LinkedIn Chrome extension covering 150M+ contacts, best for solo SDRs and small teams that need affordable B2B contact data. A permanent free tier gives 25 email and 25 enrichment credits per month, and Starter costs $49/mo. Skip it if you need 95%+ email accuracy, high daily volume, or fast support.

> **TL;DR** 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.

- Your TAM fits the 150M+ contact DB scope (US/EU mid-market)

### Skip if

## 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 pricing

| Plan | Price | Best for | 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 |

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.

### 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.

## Pros

### 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.

> "Tested 5 affordable contact DBs. Adapt.io was the highest-rated and the experience matched - clean Chrome extension, reasonable accuracy, fair pricing for solo SDR use." (Verified G2 user, BDR, G2 review (Q1 2026))

### 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.

> "Adapt.io's filters let me build mid-market SaaS prospect lists in minutes. Chrome extension on LinkedIn is clean - one-click email + phone reveal." (Verified G2 user, Sales Manager, G2 review (Q4 2025))

### 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.

## Cons

### 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.

> "Bounce rate ran 12% on Adapt.io data. Migrated to Hunter for verification on top - added cost erased the original Adapt savings." (Verified G2 user, Outbound Lead, G2 review (Q1 2026))

### 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.

> "Hit the 100/day cap by 11am most days on Basic. Couldn't justify Custom upgrade for our 3-person team - migrated to Apollo Pro Unlimited." (Verified G2 user, BDR Manager, G2 review (Q4 2025))

### "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.

Derrick is the contact data layer that finds + enriches contact data in its web app or Google Sheets - comparable accuracy + phones + LinkedIn data with a free plan to start, with no daily caps or credit limit complaints. Most outbound teams should test <a href='https://app.derrick-app.com'>Derrick (free)</a> first; consider Adapt.io Starter only if you specifically need the 150M+ DB scope at $49/mo entry.

## Use Adapt.io if

| [Apollo](https://derrick-app.com/tools/apollo-review) | All-in-one contact data + outbound | $0-119/user/mo | Larger DB (275M+) + bundled dialer + sequencer; better unit economics at scale; transparent pricing |

## Verdict

**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 starts free as the data layer** that delivers comparable accuracy + phones + LinkedIn data without daily caps, credit complaints or India-timezone support friction.

## FAQ

### Is Adapt.io free?

Yes - Adapt.io offers a permanent free plan with 25 email + 25 enrichment credits per month, full Chrome extension access, advanced filters, list building and email support. Paid plans start at $49/month annual ($59/month monthly) for the Starter plan with 500 credits/month.

### How much does Adapt.io cost in 2026?

Free: €0 (25 email + 25 enrichment credits/mo). Starter: $49/mo annual (500 credits, no phones). Basic: $99/mo annual (1,000 email + 100 phone + 1,000 enrichment credits, CRM export). Custom: contact sales for tailored credits + API access + dedicated CSM. Annual billing offers 20% savings across all paid tiers.

### How accurate is Adapt.io?

Adapt.io's email accuracy is mid-tier - 14 G2 reviewers flag incorrect emails as a recurring issue, with real-world bounce rates higher than UpLead's 95% accuracy guarantee or Hunter's <3% bounce in independent testing. For deliverability-sensitive cold email at scale, pair Adapt.io with a verifier (Findymail, Hunter) for production motions.

### Adapt.io vs Apollo - what is the difference?

Apollo has a larger 275M+ contact DB + bundled dialer + sequencer at $0-119/user/mo. Adapt.io has a smaller 150M+ DB at $49-99/mo with a focused contact-data positioning. Pick Adapt.io for solo SDRs on tight budgets needing US/EU mid-market coverage; pick Apollo for broader DB + bundled outbound infrastructure with better support.

### Why is daily contact limit a bottleneck?

On the Basic plan, 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 (Apollo Pro Unlimited, Cognism custom pricing). For solo SDRs at low volume, the cap is rarely hit.

### Where is Adapt.io based?

Adapt.io is headquartered at Annamalai Industrial Park, Coimbatore, Tamil Nadu 641048, India. Founded in 2016, the company has grown to 500+ customers, $2.1M ARR and a 4.6/5 G2 score across 2,789 reviews - among the higher-rated affordable B2B contact data platforms in the category.

### Does Adapt.io include phone numbers?

Phone numbers are gated to Basic tier ($99/mo annual) and above. Free and Starter tiers are email-only. Basic includes 100 phone credits/month - modest for phone-heavy outbound motions. For phone-heavy workflows, Cognism (EMEA), Lusha (US) or <a href='https://app.derrick-app.com'>Derrick</a> (web app) deliver more phone capacity.

### Adapt.io vs Derrick - what should I pick?

Different tools at different price points. Adapt.io is the affordable B2B contact database with 150M+ contacts ($49-99/mo annual). Derrick is the contact data layer that finds + enriches contact data in its web app or Google Sheets - comparable accuracy + phones + LinkedIn data with a free plan to start, with no daily caps. Most outbound teams should test Derrick first; consider Adapt.io only if you specifically need the 150M+ DB scope at $49/mo entry.
