What is Bytemine?
Bytemine is a B2B data platform and API for sales, marketing, RevOps, and AI teams that need real-time contact, company, and consumer data without heavyweight contracts. It provides searchable access to more than 130 million B2B contacts, tens of millions of mobile numbers, and over 150 million consumer records. Teams use it to build prospect lists, enrich CRMs, and feed AI agents like Claude or custom workflows with verified emails and phone numbers.
Bytemine combines low per-record pricing and unlimited seats with an AI-native delivery stack that includes an MCP server for Claude and Cursor plus developer-friendly REST APIs and code examples. Instead of centering on per-seat contracts, it positions itself as an API-first contact layer that plugs into CRMs, GTM automation, and LLM agents. That emphasis on programmatic access and AI workflows is less common among traditional contact data providers.
Bytemine gives sales, marketing, and product teams a programmable contact data layer built for AI-era workflows rather than legacy seat-based contracts. It is best suited to groups that value APIs, MCP tools, and low per-record costs more than having a full engagement suite in one product. Teams that require audited security certifications or independent accuracy studies will need to do extra diligence, but builders and revenue teams comfortable testing data will find it a strong engine for modern GTM.

How Bytemine fits into your stack
Browser

Teams upload CRM or prospect CSV files for bulk enrichment, automatic column mapping, data hygiene, and export of enriched records.
Automation and APIs
REST APIs, batch processing, webhooks, SDKs, CLI, and MCP let engineering teams connect Bytemine to data pipelines and AI-agent workflows.
Desktop / IDE
Bytemine's MCP server connects with clients such as Claude Desktop and Cursor, allowing those environments to search and enrich B2B data.
Pros
- +AI-native delivery: Native MCP server, Claude and OpenAI integrations, and prompt enrichment patterns fit modern LLM and agent workflows.
- +Generous free tier: Starter plan grants 500 credits per month for 12 months with the same feature set as Pro, which is strong for trials and small teams.
- +Low effective cost per record: Published pricing comes out to roughly $0.03 per fully enriched contact while still including unlimited seats and exports.
- +Fast responses: Sub-200 millisecond enrichment endpoints support interactive tools and in-product personalization.
Cons
- −Limited independent validation: There are few public third-party reviews or accuracy benchmarks, so teams must run their own quality tests.
- −Sparse enterprise security signals: Beyond a privacy policy, the site does not foreground compliance badges such as SOC 2, which may slow approval with strict security teams.
- −Region coverage clarity: Marketing copy emphasizes large US mobile and email volumes, while coverage in other regions is less clearly documented.
Limitations & when to consider alternatives
Known limitations
- Free credits are time-limited. The advertised free allowance is 500 credits per month for 12 months rather than an unlimited free data plan.
- Credit-based usage. Enrichment consumes credits, generally one credit per complete contact record, and paid plans are based on usage volume.
- Credit card requirement. The primary free offer states that a credit card is required, although the site also presents other free-credit messaging.
- Browser extension scope. The dedicated extension is designed for LinkedIn and supported websites; it is not documented as a native mobile application.
Look elsewhere when
- You need a native mobile app.
- You need image analysis or vision input.
- You need model fine-tuning or custom weight training.
