How to choose

Can the search express your market?

Try a specific service, product, or customer type. Check natural-language matching, exact phrases, customer lookalikes, and location filters against the same ICP.

Which accounts are new and relevant?

Exclude customers and existing pipeline. Measure accepted new companies after review, with separate results for each geography or niche.

What happens after discovery?

Decide whether you need contact search, research, CRM enrichment, or sending in the same product. Include those steps in the cost comparison.

What to account for

Outreach runs in your CRM or sequencer. A retrieved company still needs qualification against the requirements of your campaign.

Company and contact search with outreach

Apollo

Company and contact search with enrichment and outreach in the same platform. Product source

A combined data and execution workflow can reduce handoffs for teams that want to search, enrich, and contact prospects in one platform.

What to account for

Evaluate coverage in your own segment and price the contact fields and outreach features you need. A company count alone does not establish contact quality.

Discovery based on successful customer segments

Ocean.io

Account discovery and fit scoring informed by customer segments and closed-won deals. Product source

Its current positioning centers on learning from won deals, finding similar accounts, and explaining fit. This suits teams with customer patterns they want to extend.

What to account for

The quality of your starting customer segments matters. Confirm current pricing and integrations for the workflow you plan to run.

Write an ICP you can test

Replace a broad label such as manufacturing with a target you can recognize: contract manufacturers producing sterile medical packaging in Germany. Decide which traits are required and which are preferences.

Run the same brief in each candidate product. Keep the returned domain and the reason it appears relevant. Review a random sample rather than selecting only the best-looking results. You are testing whether the tool can describe and find your market.

Separate market coverage from contact coverage

Finding a company and finding a current decision-maker at that company are separate tasks. A provider can be useful for one and weaker for the other. Keep separate counts for relevant accounts, usable contacts, and confirmed handoffs to your CRM.

DiscoLike's Company Index and Company Stats help you explore the company universe before building a list. Discovery can then feed contact search and account research. If another system already handles engagement well, you can keep that workflow and improve the accounts entering it.

Compare the cost of accepted accounts

Define an accepted account before the pilot: a new domain in the target geography, providing the required service, with enough evidence for a salesperson to act. Divide the full pilot cost by accepted accounts, and record review time separately.

Include subscription fees, records retrieved, enrichment, and repeat retrieval rules. A low export price can still leave substantial manual qualification. A more expensive workflow can be worthwhile if it completes the steps your team actually needs.

Common questions

How is company discovery different from firmographic filtering?

Firmographic filters use attributes such as location, industry, and size. Company discovery can also use website descriptions, customer similarity, and specific phrases to find businesses that a broad category does not describe well.

Should I replace my CRM or sequencer?

Only if that is part of the problem you need to solve. A company discovery tool can supply a better account list to your existing sales workflow.

How do I compare coverage fairly?

Use the same ICP, geography, exclusions, and review criteria. Count relevant new accounts, not just rows returned, and keep contact quality as a separate measure.
