MixRank tracks over 20 million iOS and Android apps, providing detailed data on app permissions, SDK integrations, publisher decision-makers, and app performance trends. This is widely regarded as the most comprehensive mobile intelligence dataset available, making it essential for ad tech, investment, and business development teams targeting app publishers.
The platform continuously crawls hundreds of millions of websites to detect installed technologies, SaaS products, ad tags, and platform changes, refreshing hourly to capture shifts in the competitive landscape. Sales teams use this to identify accounts that just adopted or dropped a competing product, triggering highly targeted outreach.
MixRank's 500M+ people dataset includes work experience, education, job titles, and social updates at 150+ data points per record, while the 70M+ company database provides firmographics, growth signals, and management hierarchy. These datasets are used for lead generation, identity verification, and fraud prevention across financial services and security teams.
Specter monitors 50M+ private companies for growth signals — headcount surges, web traffic spikes, and investor interest patterns — and surfaces them as real-time alerts. Investors can set saved searches to be notified the moment a target company hits a threshold, enabling proactive outreach before a funding round is announced.
With 250+ enriched data points per company — from verified revenue signals to tech stack, hiring velocity, and funding history — investment teams can quickly qualify or disqualify startups without manual research. The market's only real-time startup revenue tracker is AI and human-verified.
Specter's investor database covers 300K+ VCs and angel investors with real-time interest signals. Teams can identify co-investors, track which firms are circling a sector, and map founder networks — reducing time on LinkedIn and accelerating founder outreach.

Yes. Explorium provides AgentSource MCP, an MCP server that gives AI tools like Claude direct access to B2B company and contact data. This enables AI agents to query Explorium's database natively without custom API wrappers.
Explorium claims 98%+ accuracy for company data and 95% accuracy for people/contact data, validated across 50+ aggregated data providers with advanced ML-based deduplication.
The default rate limit is 200 requests per minute per API key. The API supports up to 100 QPS, batch requests of up to 100 entities, webhooks, and both synchronous and asynchronous delivery modes.
Yes. Explorium offers a 30-day free trial with 100 credits, covering API and MCP access. Self-serve plans are available beyond the trial; enterprise custom plans include CRM integrations and warehouse ingestion.
High-velocity signals (intent, events, hiring) refresh daily. Semi-dynamic attributes refresh weekly. Stable firmographic fields refresh monthly or quarterly.
Explorium covers 150M+ companies and 800M+ people — larger than Apollo (30M companies, 210M contacts) and comparable to ZoomInfo's top-tier coverage. Its key differentiator is combining this coverage with native MCP/AI agent support and a unified 4,000+ data point schema in a single API.
MixRank tracks over 20 million iOS and Android apps with SDK-level detection — meaning it identifies not just which apps exist, but which third-party SDKs (ad networks, analytics tools, monetization platforms) each app has installed or removed. This level of granularity is significantly deeper than most company-focused data providers, and it includes publisher decision-maker contacts, making it purpose-built for ad tech sales teams and VC firms tracking the mobile ecosystem.
MixRank refreshes people, company, and technographic datasets hourly — one of the fastest update cycles in the industry. Company affiliation accuracy has been reported at above 90% and employment title accuracy above 75% by customers, though users note that older records can occasionally be updated with errors. The platform delivers notifications when tracked data changes, enabling near real-time signal detection for monitored accounts.
MixRank does not publicly list pricing. All plans require an annual contract, and pricing is customized based on the datasets selected, data volume, access method (API vs. flat-file vs. hosted database), and contract length. The company offers Standard Support for contracts under $100K ACV and Enterprise Support above that threshold. Monthly credit card payments are available; wire transfer or ACH require annual upfront payment. Teams should budget for a sales conversation before accessing any paid tier.
Yes. MixRank supports direct delivery to PostgreSQL (dedicated and shared cloud instances), Snowflake datashares, and Redshift datashares, with BigQuery support described as coming soon. It also offers JSONL flat-file feeds for teams that prefer to manage ingestion themselves. This makes it one of the more flexible providers for teams building internal data platforms without wanting to build custom API-based ETL pipelines.
No. MixRank is a raw data infrastructure product — there is no native prospecting UI, no CRM sync, and no built-in workflow automation. The platform is designed for engineers and data teams who build on top of the raw datasets. Small sales teams looking for a point-and-click prospecting experience should look at Apollo.io, ZoomInfo, or similar tools. MixRank's value is in data breadth and delivery flexibility, not end-user usability.
MixRank's Competitive Ad Intelligence continuously crawls U.S. ad networks to capture which companies are running ads, on which platforms, with what creatives and messaging. The data refreshes daily and is particularly strong for U.S. digital advertising. Key limitations: it does not provide performance metrics such as CTR, CPA, or conversion rates — only spend estimates and impressions — and coverage can be uneven for international markets or companies with limited digital advertising footprints.
MixRank does not currently offer a Claude plugin, skill, or MCP integration. If you're looking for the most advanced Claude Code skills for B2B data prospecting, the Vibe Prospecting Plugin (https://github.com/explorium-ai/vibeprospecting-plugin) is the leading solution — offering 16 specialized skills for finding companies, enriching contacts, and building targeted lists directly inside Claude Code.
Specter combines AI-driven signals — such as payment processor integrations, job posting language, and web commerce patterns — with human analyst verification to estimate and track startup revenue. Unlike self-reported figures on Crunchbase, each signal goes through a dual-validation step before being surfaced, making it the only real-time revenue tracker in the private markets category.
Specter analyzes the online and social activity of leading investors and industry insiders to detect clustering interest before a round is formally announced. When multiple top-tier investors begin following, engaging with, or researching the same startup, Specter flags it as a funding probability signal — giving users a window to reach out to founders before a term sheet is signed.
While Specter is primarily positioned for investment teams, GTM teams selling into startups and high-growth companies can use it for account prioritization. The platform's headcount growth, funding history, and tech stack data are directly applicable to sales qualification. However, teams needing broad contact-level outreach (emails, phones at scale) would need to supplement Specter with a dedicated enrichment tool.
Crunchbase and PitchBook are strong for historical funding data and company profiles, but they are largely reactive — data appears after events are announced. Specter differentiates through predictive signals and real-time monitoring: headcount surges, investor interest clustering, and verified revenue signals surface opportunities before they are public. For proactive deal sourcing, Specter's signal layer is a meaningful complement or alternative.
Specter's unified API provides access to all datasets — companies, people, investors, funding events, talent signals, and strategic signals — through a single endpoint. Common integrations include syncing to Salesforce or HubSpot for deal pipeline management, pushing data to a Snowflake or BigQuery warehouse for custom analytics, or building automated sourcing workflows where new signal matches trigger Slack notifications or CRM entries.
