How each directory is built
AI Ark positions itself against stale, LinkedIn-derived data, and on that diagnosis we agree. It assembles its database from "established, legally compliant B2B data vendors" plus its own indexing of corporate websites.
DiscoLike's company directory comes from business websites. Every company is classified from what its site says, geolocated, and placed in one of close to 300 SMB sub-industries, at over 99% company-record accuracy. The directory covers 87M+ business websites, 98% of businesses with a website, with 3x LinkedIn company coverage and 2x Google Maps coverage. A lookup returns every company that matches, not a ranked top N.
Both reject stale profile data. DiscoLike selects for ICP and role fit, supported by territory and sub-industry targeting.
Test it in a specialist service market
Use a market where you can check the answers, such as independent dermatology practices in two metro areas. In DiscoLike, define the radius and sub-industry, add an ICP sentence, and rank by size. In AI Ark, build the closest company search. Check business type and location first and count accepted practices.
Then move to people. Check current role affiliation and email status at the same practices: DiscoLike's contact search, email verification in real time with catch-all resolution. Keep account coverage separate from the number of contact fields returned; a long export of contacts at the wrong businesses is not progress.
Measure accepted accounts first, then usable contacts at those accounts.
Proof you can look at
AI Ark publishes its own figures for profiles, accuracy, and bounce rates. Test them on your segment, as you should with any vendor, DiscoLike included.
DiscoLike's customers have published their results: ColdIQ added 2,000 qualified accounts and 15,000 contacts using DiscoLike discovery with Clay qualification, and PipeRich reports 2.8M net-new domains across 720 campaigns with about 1.8x the qualified-account yield of its next source. See the ColdIQ case study and PipeRich case study.
Where AI Ark genuinely wins
Entry price. A free plan and a $49/mo usage plan undercut most of the category, including our subscriptions. Credits roll over up to twice the monthly allowance, and paid plans are 20% off annually. Its catch-all email validation at export is a substantive capability for agencies pushing high volumes. If your constraint is budget and the target companies are already easy to describe with filters, AI Ark is worth a pilot. Measure the results against ours.
Agent flows: from no account to first search
On DiscoLike the whole flow runs without a person opening a browser until payment. The agent posts the person's work email and name to POST /v1/public/signup, relays the next_step text, and the person confirms by email, keeps Pay as you go or subscribes, and authorizes the MCP client or issues a key. From there the agent authenticates with OAuth 2.1, so no secret sits in a config file, calls count before any large search so it knows the spend, and reads pricing.md, mcp.md, api.md, and llms.txt for the rules. The CLI emits JSON, the Python SDK validates parameters locally, and a published skill teaches Claude Code, Codex, and Cursor when to reach for all of it.
AI Ark's MCP server at api.ai-ark.com/v1/mcp is official, with a community-built alternative on GitHub, and authenticates with the API key as a token in the URL. Its tools are data queries plus documentation search. The docs describe no agent-driven account creation and no cost preview; the person signs up in the web app, generates a key, and pastes it into the client config.
AI Ark's agent flow is key-in-URL and human-created account. DiscoLike's is OAuth and agent-created account.

FAQ
Common questions
Aren't DiscoLike and AI Ark making the same claim?
Both argue against stale, profile-derived data. The construction differs: AI Ark combines vendor data with its own indexing of corporate websites, while DiscoLike's company directory is built from 87M+ business websites, geolocated and classified into close to 300 SMB sub-industries. DiscoLike also covers the steps after discovery: fit validation, research, contacts, and email verification.
AI Ark is cheaper. Why pay more for DiscoLike?
AI Ark's free plan and $49 entry are genuinely cheaper. DiscoLike Starter at $99 gives you ICP and role search through email verification in one platform, with local and sub-industry targeting available. Compare cost per accepted account and per usable contact on the same segment.
Can AI agents use both tools?
Yes. Both ship MCP servers. An agent on DiscoLike's MCP can count matches for free, pull the complete matching set, then run research, contacts, and email verification. Choose by the work your agent needs to finish, not the connector.
Should I pilot both?
Reasonable. Run the same ICP through both. DiscoLike is self-serve on Pay as you go or subscriptions from $99/mo, billing only new records. Records retrieved within 24 hours on Pay as you go or 30 days on subscriptions are free to retrieve again; older records are chargeable again. Compare how many accepted companies each finds that the other misses, then the usable contacts at each.
Does AI Ark have an MCP server, and how does DiscoLike's compare?
Yes. AI Ark documents an official remote MCP server at api.ai-ark.com/v1/mcp with the API key passed as a token in the URL, plus a community-built server on GitHub. Its tools are data queries and documentation search. DiscoLike's MCP server uses OAuth 2.1 instead of a key in the URL and adds lookalike search, exact homepage phrase matching, segmentation, ICP validation, and optional CRM push on top of company and contact lookup.
