Sendburg is a B2B contact database and sales intelligence platform for sales, marketing, and RevOps teams. It aims to replace multiple tool categories—email finding, company intelligence, buying intent signals, tech stack identification, and CRM enrichment—with a single platform. The site states that it serves 1,000+ revenue teams across 40+ countries, with a positioning that leans toward outbound B2B lead generation and sales development for international markets.
The platform offers Email Finder, Verified Direct Dials, Company Intelligence, Buying Signals, Tech Stack Filter, Burg AI, a Chrome extension, CRM Enrichment, an MCP connector, and a REST API. In terms of data scale, Sendburg claims to provide 150M+ verified B2B contacts, 10M+ company profiles, 14,000+ tracked tools, and 300+ signal types. Signal sources include hiring activity, funding, leadership changes, technology adoption, news, company websites, and public professional profiles. It also states that it does not buy data from third-party data brokers, and that contacts are re-verified on a 90-day cycle.
Pricing is relatively transparent: the Free plan is free forever, includes 1,000 credits/month, and does not require a credit card. Growth costs $29/month, with 5,000 credits/month and 3 seats. Scale costs $89/month, with 20,000 credits/month, unlimited seats, plus the REST API, MCP connector, priority support, and SLA. Annual billing saves 20%, there is no annual contract, and users can cancel. A paid trial must be requested via the demo form, while teams with 10+ seats or high-volume enrichment needs can request a custom enterprise plan.
The main advantages are its generous free allowance and low barrier to entry. Its feature set covers contact discovery, company research, buying-timing signals, and CRM push workflows, making it suitable for quickly building outbound calling or email prospecting processes. It also supports ecosystems including Salesforce, HubSpot, Pipedrive, Outreach, Instantly, Lemlist, Claude, and ChatGPT. Limitations include SOC 2 Type II still being in progress, no mention of payment methods commonly used in China, and no disclosure on data coverage or access stability in mainland China. Some key features, such as direct dials, CRM integrations, MCP, and API access, are concentrated in paid tiers.
Sendburg is better suited to B2B sales teams, SDR teams, growth marketing teams, SaaS companies, and agencies targeting Europe, North America, or broader international markets. For Chinese users doing overseas lead generation, it can be used as an alternative or supplement to Apollo.io, ZoomInfo, or Lusha. The site does not provide information on availability from mainland China, and the only clearly stated payment options are PayPal and Cashfree, so network access and payment convenience should be tested in practice.
