Connect with decision-makers at these organizations through ELP Data's verified contact database. Organizations across Technology, Financial Services, Healthcare represent the strongest user base, making BLACKHOLE contacts a high-value segment for complementary solution providers, implementation partners, and specialist consulting firms.

ELP Data's verified BLACKHOLE users list gives you direct access to 85,668 confirmed companies running BLACKHOLE in their technology stack. Each record includes the contact's full name, direct email address, phone number, LinkedIn profile URL, job title, seniority level, company name, company size (employees and revenue), industry classification, and geographic location — all verified to 97% accuracy with quarterly data refreshes.

The typical BLACKHOLE buyer and decision-maker profile includes Database Administrator, Data Architect, VP Engineering — professionals with direct budget authority and technology purchasing influence at their organisations. These contacts are actively evaluating software solutions that integrate with, extend, or complement their existing BLACKHOLE environment, making them highly receptive to targeted B2B outreach from relevant vendors and service providers.

Companies that purchase the BLACKHOLE users list from ELP Data use it for a wide range of B2B sales and marketing campaigns: selling complementary software integrations, offering BLACKHOLE implementation and customisation consulting, promoting training and certification programmes, running account-based marketing (ABM) campaigns by industry or company size, and competitive displacement targeting. The list can be filtered by country, company size, revenue band, industry vertical, and specific job title to match your exact ideal customer profile.

The BLACKHOLE installed base spans companies of every size — from fast-growing mid-market firms to Fortune 500 enterprises with global deployments. This diversity means the list serves multiple go-to-market motions simultaneously: enterprise sales teams can filter for companies with 5,000+ employees and specific industry codes, while SMB-focused vendors can target the long tail of smaller organisations that have adopted BLACKHOLE for the first time. Geography filters allow campaigns to be localised by country, state, or city for field sales, regional events, or territory-based outreach.

ELP Data sources BLACKHOLE install data from technology job postings, LinkedIn technology signals, integration partner directories, software review platforms, and verified firmographic databases — then cross-references every record against live business registries and direct email verification tools. The result is a list that reflects who is actually running BLACKHOLE today, not who ran it two years ago. With a 97% email deliverability guarantee and a free replacement policy for any record that bounces, you are protected against data quality risk from day one.

The total addressable market for vendors targeting BLACKHOLE users is defined by the 85,668 confirmed companies currently running BLACKHOLE worldwide. This installed base represents the universe of organisations that have already invested in the Database Management (DBMS) category — meaning they have validated budget, a procurement process, and active technology decision-makers in place. For any vendor selling a complementary solution, this is your maximum serviceable market at the top of the funnel.

Within the 85,668 total companies, the realistic serviceable addressable market (SAM) narrows based on your product fit, target company size, and geographic focus. For example, an enterprise software vendor targeting companies with 1,000+ employees operating in financial services would find approximately 32% of the list — or 27,414+ companies representing their highest-priority accounts. The ability to slice the BLACKHOLE list by industry vertical, company size band, revenue range, and geography is what converts a broad TAM into an actionable pipeline.

Decision-maker density is a critical TAM multiplier. Most of the 85,668 BLACKHOLE companies have multiple relevant contacts — the average enterprise has between 3 and 7 decision-makers involved in a technology purchase. ELP Data maps all relevant titles at each account: Database Administrator, Data Architect, VP Engineering, IT Director and more. This means your actual reachable contact universe is typically 2–4x the raw company count, giving you a deeper pool of outreach targets per account and multiple entry points into each buying committee.

The BLACKHOLE installed base represents one of the most commercially valuable B2B target segments available. Companies that have already invested in BLACKHOLE have demonstrated a willingness to purchase and deploy enterprise software — they have budget, a procurement process, and decision-makers who are accustomed to evaluating technology solutions. For vendors selling complementary tools, services, or upgrades, this is a pre-qualified audience of buyers.

Unlike generic email lists or broad industry databases, the BLACKHOLE users list is built on verified technology install signals. ELP Data tracks which companies are actively running BLACKHOLE through job postings, LinkedIn technology signals, integration partner data, and direct verification — meaning every company in the list is a confirmed BLACKHOLE user, not an estimate. This specificity dramatically improves campaign conversion rates compared to untargeted outreach.

The decision-makers in this list — Database Administrator, Data Architect, VP Engineering, IT Director — hold direct budget authority for technology purchases in the 85,668 companies using BLACKHOLE. They are actively engaged with the Database Management (DBMS) ecosystem, making them highly receptive to relevant vendor outreach, especially for solutions that integrate with, extend, or modernise their existing BLACKHOLE environment. Timing matters: companies that have recently deployed BLACKHOLE are in an active expansion phase and are most likely to purchase additional solutions.

ELP Data refreshes the BLACKHOLE users list quarterly, removing companies that have churned off the platform and adding newly identified users. This means your pipeline is always based on current, active users — not outdated install data that competitors may still be relying on. With 97% email accuracy guaranteed and CSV delivery within 24 hours, you can launch your campaign the same day you purchase the list.

For sales teams running territory-based motions, the BLACKHOLE list can be sliced by geographic region to build focused prospect sets for each account executive. For channel partners and resellers, the list is a powerful tool for identifying end-customer accounts where a conversation about BLACKHOLE licensing, support, or expansion is immediately relevant. Whatever your go-to-market model — direct sales, channel, or inbound-assisted — the BLACKHOLE installed base is a commercially actionable starting point that eliminates the prospecting phase and lets your team focus on selling.
