    Good, but Not the Best B2B Database

    As a B2B database, ZoomInfo certainly has a lot to offer. Its detailed business information on people and companies is impressive, and I've found it to be a useful resource for researching potential clients and partners.

    However, I do have a few criticisms of the product. Firstly, its pricing is quite steep, especially compared to other B2B databases on the market. This makes it difficult for smaller businesses or startups to justify the cost. Additionally, while the information on ZoomInfo is generally accurate and up-to-date, I have come across a few instances where the information was incomplete or outdated.

    Despite these drawbacks, ZoomInfo is still a good resource for business information. It just might not be the best option out there. If you're willing to pay for a premium service, then ZoomInfo could be worth considering. However, if you're looking for more cost-effective alternatives, there are several options to consider.

    Pros:    Detailed|Accurate
    Cons:    Expensive|Incomplete

ZoomInfo vs Lusha vs Apollo vs MillionPhones: 2026 Comparison
ZoomInfo is the industry standard. Their database is massive, their intent data is best-in-class, and enterprise sales teams swear by it. The catch: pricing starts around $15,000/year and requires an annual contract. If you're an SDR team of 10+ at a well-funded company, it's worth it. If you're a solo founder or small team, it's overkill.

  • Enriching Free Trial Signups: The PLG Data Stack for Turning Inbound Users Into Qualified Pipeline
    Skip ZoomInfo for this use case. It's enterprise-contract priced, built for outbound prospecting from company lists, and adds zero value for personal email resolution. Same story with Lusha — excellent for Chrome extension-style lookups starting from a LinkedIn profile, wrong tool for an automated inbound pipeline. - Source: dev.to / 4 months ago
  • How to Build an OSINT-Powered B2B Prospecting Workflow in 2026 (Without Getting Banned)
    Most SDR stacks start with a contact database — ZoomInfo, Apollo, or Lusha — and treat enrichment as a one-time step at the top of the funnel. The problem: these databases are 3–18 months stale on average. Job titles change. Companies restructure.

  • Forward spam emails back to sender!
    I just found a few data collator sites, zoominfo.com and signalhire.com are just two - they seem to scrape sites like Linkedin etc and collate everything. Personal numbers can be found pretty easily, if you've ever signed up for a business identification number it could be there, could be in a data leak somewhere - these companies are pretty shady and will buy data from places to just get a lead.
