CompanyData.com (BoldData) vs Leadzen.ai in 2026
Comparing CompanyData.com (BoldData) vs Leadzen.ai is like comparing a lumber yard to a carpentry shop. One sells raw materials in bulk. The other promises to build you the finished product - meetings on your calendar. The only thing they share is the word "leads" somewhere in their marketing copy.
BoldData rebranded to CompanyData.com in September 2025, but the product hasn't changed: it's a bulk firmographic data provider powered by official trade registers in 200 countries. Leadzen.ai is an AI SDR platform focused on booking confirmed meetings, with an India-first go-to-market and broader APAC positioning. We've dug into both platforms' product pages and pricing structures, and here's the honest truth - if you're comparing these two, you're probably trying to solve a problem that neither one perfectly addresses.
30-Second Verdict
- Need bulk firmographic data for compliance, KYC, or large-scale data projects? CompanyData.com. It's a data warehouse, not a prospecting tool.
- Running AI-driven outbound targeting India specifically? Leadzen.ai - though their own blog admits it's not suitable for EU/US campaigns.
CompanyData.com Overview
CompanyData.com covers 400M companies across 200 countries, with 607M contacts, 175M phone numbers, and 48M email addresses. The database adds roughly 2M new companies per month, all powered by official trade registers and chambers of commerce - no scraping. That trade-register sourcing means the firmographic data stays relatively fresh for compliance use cases, since it's tied to government filing cycles rather than web crawlers.
The company has been around since 2013, operates out of Amsterdam, Berlin, and Dubai, and counts 5,000+ clients. They display a 9.2/10 on Kiyoh across 85 reviews, but there's no meaningful footprint on G2 or other mainstream software review platforms. CompanyData.com isn't a prospecting tool - it's a data supply chain. You buy lists in bulk via CSV, JSON, or API for enrichment, analytics, or compliance workflows. If you're a sales rep who needs 200 verified emails by Friday, this isn't your product.
Leadzen.ai Overview
Leadzen.ai positions itself as an AI SDR that converts website traffic into confirmed meetings. It supports multi-channel outreach across email, WhatsApp, and AI-driven voice calls in 105+ languages, with a Chrome extension for revealing contact details while browsing websites and professional profiles.
The platform's real strength is hyperlocal targeting in India - it offers PIN-code level filtering that's genuinely useful for regional campaigns. About 200+ companies use it. Leadzen's own blog acknowledges it's "not suitable for EU/US campaigns," and it also highlights a limitation: it lacks built-in outreach automation like email/call sequences.
Like CompanyData.com, Leadzen has zero G2 reviews. Neither tool has meaningful third-party review coverage, and there's essentially no Reddit discussion about either product. That alone tells you something about their market penetration outside their core niches. For broader context, one Reddit user testing AI lead gen platforms reported bounce rates of 19-31% versus about 8% with manual prospecting - which is exactly why transparent verification matters when you're buying "AI leads."
Neither BoldData's EUR425 minimums nor Leadzen's 3-month lock-ins give you campaign-ready emails fast. Prospeo delivers 300M+ profiles with 98% email accuracy, 30+ filters including buyer intent, and a 7-day data refresh - all self-serve with no contracts.

Pricing Breakdown
CompanyData.com starts at EUR425 for 1,000 B2B addresses. Scaling up, 50,000-100,000 companies runs EUR3,925-EUR5,175. Bold Bulk datasets typically start at 1M records for around EUR10,000. This is enterprise data procurement pricing, not self-serve prospecting.
Leadzen.ai has two different pricing models, and the lack of a clear "which one should I buy?" explanation on their site is genuinely frustrating:
- A credit-based plan ranges from $133/month for 300 credits up to $800/month for 2,600 credits.
- The AI SDR "confirmed meetings" packages run $2,000-$8,000 depending on meeting volume, with a 3-month minimum commitment.
Which One Should You Pick?
Pick CompanyData.com if you're running enterprise data projects - compliance checks, KYC workflows, bulk firmographic analysis. You need volume, you have budget, and you're buying raw data as infrastructure. It's not a tool for sales reps; it's a tool for data teams.
Pick Leadzen.ai if you're targeting India and want an AI-driven outbound engine with hyperlocal filtering and a "confirmed meetings" package. Don't expect it to work for US or European campaigns - they say so themselves.
Skip both if your sales team needs verified emails for a campaign next week. We've tested dozens of data providers over the years, and self-serve tools consistently outperform bulk data providers for campaign-speed use cases. Prospeo covers 300M+ professional profiles with 98% email accuracy, a 7-day data refresh cycle, and 30+ search filters including buyer intent and technographics - all self-serve and exportable in minutes. Our customers like Meritt report bounce rates under 4%, compared to the 19-31% bounce rates seen with AI lead gen platforms. That gap isn't marginal. It's the difference between a healthy sending domain and a blacklisted one.
When comparing CompanyData.com (BoldData) vs Leadzen.ai, the real takeaway is that they serve fundamentally different buyers. If neither matches your workflow, a self-serve data platform with verified contact data will get you to pipeline faster than either option. If you're building your outbound motion, start with proven sales prospecting techniques and a clean list.
AI lead gen tools average 19-31% bounce rates. BoldData sells raw firmographic data, not verified contacts. Prospeo's 5-step verification keeps bounce rates under 4% - just ask Meritt, who tripled their pipeline to $300K/week on our data.
Protect your domain with emails that actually land.
