Enrich Company Data: 7 API Tools Compared for Real Leads (2026)

I keep seeing the same pattern. A founder or ops person needs company data – funding rounds, employee count, tech stack, maybe a phone number that actually works. They Google “company data API,” find ZoomInfo, see the $15,000/year price tag, and either overpay or give up.

Clearbit doesn’t even exist as a standalone product anymore. And that data tool your sales team signed up for last month? It returns the same 15 fields for every company – industry, size, location – and calls it “comprehensive.” Fifteen fields. For $200/month.

I spent two weeks testing 7 APIs. Not reading pricing pages – actually calling their endpoints, checking what comes back, and doing the per-lead math.

Most of these tools hand you a fixed data model at a fixed price. You get whatever they have. Period. But there’s an approach that none of the “top 10 data tools” listicles mention: combining specialized APIs into a stack that returns more data for less money than any single tool.

TL;DR: A FlyByAPIs stack of Crunchbase + Google Maps + Jobs APIs costs $39.97/month. That covers funding, contacts, and hiring signals across 46 endpoints – richer data than Clearbit ever offered at 10x the price. 3,300x cheaper than ZoomInfo’s enterprise tier.

Here’s what I found.

All 7 company data APIs at a glance

Before the deep dives, the pricing reality across all 7. I verified these from each provider’s website in May 2026.

Now let’s break each one down.

1. FlyByAPIs – four APIs, one data pipeline

FlyByAPIs isn’t one monolithic API. It’s four specialized APIs you combine based on what you actually need.

Most data tools give you a fixed model. Their 30 fields, take it or leave it. Need hiring signals? Too bad. Need Google Maps reviews for reputation scoring? Not available. Need web presence data? Go find another vendor and stitch it together yourself.

With FlyByAPIs, you pick the APIs that match your use case:

The math: Crunchbase API Pro ($14.99/mo, 5,000 requests) + Google Maps Pro ($14.99/mo, 10,000 requests) + Jobs Pro ($9.99/mo, 10,000 requests) = $39.97/month. Richer data than Clearbit offered at 10x the price.

Need more volume? Crunchbase Ultra ($49.99) + Google Maps Ultra ($89.99) + Jobs Ultra ($49.99) = $189.97/month for 290,000 API calls covering company intel, physical data, and hiring signals. ZoomInfo charges more than that for a single seat.

Every API has a free tier. No credit card. Per-request billing, no per-field charges. One call to the Crunchbase company details endpoint returns the full profile: funding, investors, growth score, tech stack, key people. Not a stripped-down summary that makes you upgrade for the interesting parts.

And because all four APIs run through RapidAPI, you get one API key, one billing dashboard, one integration pattern. No stitching together four different vendors.

2. Clearbit (Breeze Intelligence) – the gold standard, now behind a paywall

Clearbit used to be the company data API. Clean data, simple REST endpoints, generous free tier. Then HubSpot bought them in December 2023 , rebranded everything as “Breeze Intelligence,” and locked it inside their CRM.

If you’re already paying for HubSpot Professional or Enterprise, the data is good. 55+ company attributes: industry classification down to sub-industry level, SIC/NAICS/GICS codes, tech stack detection, estimated revenue, funding raised, corporate hierarchy. The person-level API adds 40+ attributes per contact.

But if you’re not on HubSpot? Locked out. No standalone API for new users. Existing API keys still work, but there are no new features and the full sunset is coming.

Pricing reality: You need a HubSpot subscription plus Breeze Intelligence credits. $60-75/month at the startup end. $950-1,040/month for mid-market (Professional tier). $4,000-5,500/month for enterprise. Credits expire monthly, no rollover. Standalone API access requires a custom enterprise deal at reportedly $20,000+/year.

Verdict: Already deep in HubSpot? Breeze Intelligence is worth a look. For everyone else, especially startups watching their burn rate, it’s overkill. You’ll get comparable company data from a Crunchbase extraction API at a fraction of the cost, without being locked into a CRM you might not need.

3. People Data Labs – deepest data, steepest learning curve

People Data Labs is for teams that want to go deep. Their company schema includes things no other API here tracks: employee turnover rates, tenure breakdowns by role, executive hiring and departure signals, growth rates by country, full corporate hierarchy with parent/subsidiary relationships.

The data is impressive. 70-100 million companies, 3 billion person records, workforce analytics that let you spot companies scaling engineering teams or losing senior leadership. If you’re building an investment research platform or a competitive intelligence tool, PDL’s depth is hard to beat.

The catch: it’s API-only. No UI, no dashboard, no CRM integrations, no Zapier connector, no HubSpot sync. Average implementation time is reportedly 2 months. If you don’t have an engineer who can build and maintain the integration, this isn’t for you.

Pricing: Free tier = 100 lookups/month, basic fields only (no emails or phones). Pro plan is $98/month for 350 person credits and 1,000 company lookups. Company data costs $0.065-0.10 per credit. Person lookups are $0.25+ per credit.

The gotcha: their Search API charges 1 credit per profile returned. A single search returning 50 results burns 50 credits.

Verdict: PDL is for technical teams building data products. Not for startup founders who need to populate a CRM. If you want workforce analytics and corporate hierarchy, nothing else comes close. But for most use cases, the Crunchbase API gets you 80% of the company data for a fraction of the cost, and you can add hiring signals with a Jobs Search API at $9.99/month instead of paying PDL’s per-person rates.

4. FullContact – identity resolution, not really data appending

FullContact started as a developer-friendly contact API back in 2010. Simple REST calls, generous free tier, quick setup. Then it pivoted to enterprise identity resolution, got acquired by Ziff Davis in late 2024, and became something very different.

Today it maps fragmented identifiers (emails, phone numbers, social handles, device IDs, cookies) to a single persistent “PersonID.” That’s identity resolution, which is useful for ad tech and marketing platforms. For straightforward company data appending? Poor fit.

Their company data endpoint only accepts domain input (name search was deprecated in 2022) and returns about 20 fields: basic firmographics, industry codes, key people, social links. No revenue data. No tech stack. No funding information. For a tool that claims 1 billion person profiles, the company data is thin.

Pricing: Free tier gives ~250 matches/month. Paid plans start at ~$99/month but require annual contracts ($1,200/year minimum). Setup fees run $500-$5,000. Different actions consume different credit amounts – a phone number lookup costs 8 credits, which makes budgeting a nightmare. G2 reviewers report real-world match rates around 50%, well below the claimed 85%.

Verdict: If you need consumer identity resolution for ad targeting or marketing personalization, FullContact has a massive identity graph. For B2B company data, which is what most people reading this actually want, look elsewhere. The Crunchbase API returns more company data across 37 endpoints at $14.99/month than FullContact does at $99/month with an annual commitment.

5. Hunter.io – email finder with a solid company data bonus

Hunter.io is primarily an email finding and verification tool, but they’ve quietly built a company data API that returns 100+ fields and is directly compatible with Clearbit’s API structure. Migrating from Clearbit? Hunter markets itself as a drop-in replacement: “just swap your API key.”

The company API returns firmographics, industry classification (GICS, SIC, NAICS codes), tech stack detection across 90+ technologies, funding round history with investors, and corporate hierarchy. At 0.2 credits per company lookup, it’s cheap too. On the Growth plan (EUR 149/month for 10,000 credits), each company lookup costs about EUR 0.03.

Free tier: 50 credits/month, no credit card. Unlimited team members on all plans, which is rare. Built-in cold email campaigns with scheduling and tracking. Their GDPR approach is solid – they only use publicly sourced data from the web, no third-party data purchasing.

Where it falls short: Hunter is still an email tool at heart. Company data is a secondary feature. An independent benchmark by Dropcontact measured a 32.5% effective match rate and 11.2% hard bounce rate across 20K contacts. Reddit users report 20-25% bounce rates even after using the built-in verification.

No phone numbers at all. Email only. Data freshness can lag by months. And for SMBs under 50 employees, you’ll often get generic addresses (info@, support@) instead of personal contacts.

Verdict: Hunter works well if you need email finding and basic company data in one tool. The Clearbit migration angle is smart positioning. But if what you actually need is company intelligence – funding data, growth signals, hiring velocity – you’ll want Crunchbase-level profiles for the business data and a Google Maps Scraper API for verified phone numbers, which Hunter doesn’t provide.

6. Enricher.io – cheapest per record, priciest entry ticket

Enricher.io has the lowest per-record price in the market: $0.01 per record on their pay-as-you-go plan. No minimums, no credit expiration, no commitment. Need to process 500 records once and never come back? That’s $5.

But the subscription plan starts at $279/month for 10,000 credits. That’s steep for a tool that returns 17 firmographic/technographic fields per company – industry, employee count, revenue, tech stack, funding, location, social links. It does the basics. Nothing that would make you pick it over a $14.99/month API with 37 endpoints.

No free tier. Their database claims are contradictory: the homepage says “2.5 billion profiles” while the About page says “1.2 billion.” They report 87% accuracy, but it’s self-reported with no independent benchmark.

One thing that bothers me: their CEO writes “neutral” comparison articles on the company blog (“Top 13 Data Companies”) that conveniently omit Enricher.io from the ranked list while positioning it favorably in the intro. Minor thing, but it tells you something about how they approach transparency.

Verdict: The $0.01/record pay-as-you-go works for one-off bulk jobs. For ongoing data pipelines, $279/month buys you far more data from the Crunchbase API ($49.99 for 40,000 requests, 37 endpoints) plus Google Maps extraction ($14.99 for 10,000 requests) combined.

7. Abstract API – developer-friendly, developer-shallow

Abstract API runs a suite of ~15 utility APIs, and their Company Data API is one of them. Most developer-friendly option on this list: a single GET request to companyenrichment.abstractapi.com/v2?domain=example.com returns a JSON response with 25-30 fields covering identity, location, industry (SIC/NAICS), employee count, revenue, tech stack, and social links.

Pricing is straightforward: $99/month for 60,000 requests. That’s $0.0017 per request, the cheapest per-request cost here by a wide margin. They also return a company logo URL in every response, which most competitors don’t bother with.

But “developer-friendly” and “developer-shallow” are both accurate. 25-30 fields is less than half what Hunter.io returns. No person-level data. No funding information. No intent signals. No org charts.

Their own documentation admits that “larger and/or ‘more online’ companies” get more comprehensive coverage. Translation: smaller companies come back sparse. And the free tier gives you 100 requests total. Not per month. Lifetime. Once they’re gone, you’re paying $99/month.

A mid-2025 G2 reviewer reported an unexpected price increase with no warning. The 3 requests/second rate limit on the paid plan makes batch processing of large lists impractical. And credits get consumed on failed lookups too – query an invalid domain and you still pay.

Verdict: Abstract API works for side projects and MVPs where you need basic company info fast. For anything serious – lead scoring, sales intelligence, competitive analysis – the data model is too shallow. You’ll end up supplementing it with other tools anyway, and at that point you’re better off starting with a Crunchbase API that returns 100+ fields per company from a single call.

How to enrich company data for under $100/month

If I were starting a data pipeline from scratch today, this is the approach:

Step 1: Start with Crunchbase data. The Crunchbase API is the foundation. Company name, industry, employee count, funding history, investors, growth score, tech stack, key people. That’s your firmographic and financial layer. Pro plan: $14.99/month for 5,000 requests.

Step 2: Add physical and contact data. Verified phone numbers, office addresses, business hours, customer reviews. The Google Maps data extractor fills the gap that every firmographic database has: real-world contact info that’s actually current, because it comes straight from Google Maps. Pro plan: $14.99/month for 10,000 requests.

Step 3: Layer in hiring signals. A company posting 15 engineering jobs is a different prospect than one posting zero. The Jobs Search API shows you hiring velocity, salary ranges, and role types in real time. Pro plan: $9.99/month for 10,000 requests.

Total: $39.97/month for a three-source pipeline covering business intelligence, physical contact data, and hiring signals.

Every API has a free tier, so you can validate the whole stack before spending a dollar. All on RapidAPI, one dashboard, one API key.

What to look for when choosing a company data API

After testing all seven, a few things became obvious:

Data model flexibility. One tool that returns 50 mediocre fields vs. multiple sources that each do one data type well. Crunchbase for business intelligence. Google Maps for physical/contact data. Jobs data for growth signals. Need competitive pricing intelligence? An Amazon product data API feeds e-commerce insights into your pipeline. Expanding into new markets? A translation API handles multilingual data normalization.

I’ve watched this play out with every monolithic data platform I’ve tested. They try to be everything. They end up average at all of it.

Transparent pricing. Credits that expire monthly, per-field billing, opaque “contact sales” pricing, surprise overages – all red flags. Look for per-request billing where one API call returns everything, free tiers that actually let you test, and published overage rates.

Data freshness. Any API is only as good as its last crawl. Monthly refresh cycles mean you might pull a contact who left the company three weeks ago. The APIs in this stack run active data-drift monitoring. When the source platform changes something, the parser gets patched within hours, not months.

Integration complexity. Some tools take 2 months to implement (looking at you, PDL). Others require a $20K annual contract just to get API access (hi, Clearbit). The sweet spot: a standard REST API with JSON responses, a free tier to test, no SDK dependencies.

All four APIs in the FlyByAPIs stack work with a simple GET request through RapidAPI. Same integration pattern whether you’re pulling Crunchbase funding data or Google Maps business details.

So here’s where I land: if you’re a startup founder or ops person trying to build company profiles without blowing your budget, the old playbook of buying one expensive data tool doesn’t work anymore. Clearbit is gone as a standalone product. ZoomInfo costs more than most startups’ entire tool budget. And every “top 10” listicle recommends the same enterprise platforms that start at $1,000/month.

Build a stack of specialized APIs instead. Richer data, lower cost, and you control which data sources actually matter for your use case.

Start with the free tiers: Crunchbase API (100 free requests), Google Maps API (100 free), Jobs API (200 free), Google Search API (200 free). Test your pipeline against real leads. If it works, upgrade to Pro plans and you’re under $40/month for data that enterprises pay thousands for. If it doesn’t work, you’ve lost nothing.
