Lusha delivers the contact, and GoSeek delivers the company's context
GoSeek and Lusha both serve B2B prospecting, but they deliver different things. Lusha positions itself as a B2B data and GTM intelligence layer for teams and AI agents, with verified contacts and companies. GoSeek delivers the dossier of one specific company, from its CNPJ (the Brazilian company tax ID), so the salesperson walks into the meeting knowing why this company, why now and who to talk to.
Lusha helps more with finding the email and phone of many people. GoSeek helps more with knowing why each large company in the portfolio would buy now.
What comes out about the company
Nineteen sections, each one answering a question in the sale
Lusha brings together contact data and buying signals
Based on what it presents publicly, Lusha brings together a database of verified contacts and companies, with emails and phone numbers, and dated buying signals on specific companies. Its AI ranks companies by ICP and maps the buying committee. The team uses Lusha through the Workspace, through the Chrome extension, which reveals contacts on LinkedIn, Sales Navigator and company websites, through the API or through MCP.
It has native apps for Salesforce and HubSpot, integration with other CRMs, a free plan and paid credit-based plans, and it states compliance with GDPR and CCPA and security certifications such as SOC 2 and ISO. It also states contact coverage in Brazil and South America. According to Lusha's public material, as of October 24, 2026, it offers email sending; WhatsApp and LinkedIn messaging do not appear. Its focus is contact data, and the team chooses how to reach out. For anyone who needs email and phone in volume, inside the workflow they already use, this is a strength.
GoSeek researches the company behind the contact in depth
GoSeek works on the company, not on the isolated contact. The salesperson enters the CNPJ and gets the company dossier in 7 to 15 minutes, built from 100 to 500 public sources, with an ICP fit score, power map and meeting preparation. The 19 sections are on the dossier page.

When Lusha is the better choice
Lusha tends to be the better choice when the challenge is getting the contact.
When GoSeek is the better choice
GoSeek tends to be the better choice when the challenge is knowing what to say to each company.
- Before calling, the salesperson needs to know what the company announced, which pains it stated and who decides.
- The team wants a battlecard, a 1st meeting script, discovery and MEDDPICC for each company, not just a list of names.
How to use Lusha and GoSeek together
The two complement each other when each one answers its own question:
How to choose between contact and context
Ask what holds your team back the most today. If the salesperson knows what to say but has no way to reach the person, the contact is missing, and a database like Lusha solves it. If they have the director's phone but do not know why that company would buy now, the context is missing, and the GoSeek dossier covers that part. See how GoSeek works and the plans.
What people ask about GoSeek vs Lusha
Does GoSeek find email and mobile numbers like Lusha?
On the Advanced plan, yes: the email of each person on the power map and the mobile number of whoever the cadence approaches first, with the option to look up anyone else's.
