Speedio brings lead volume, and GoSeek brings depth on the company
GoSeek and Speedio show up in the same search because both serve B2B prospecting, but they solve different stages. Speedio is known for generating lists of companies and contacts for outbound prospecting. GoSeek delivers the dossier of one specific company, so the salesperson walks into the meeting knowing why this company, why now and who to talk to.
If the question is "where will the next thousand leads come from", Speedio tends to help more. If the question is "what do I say to this company tomorrow", GoSeek tends to help more. Many operations need both answers.
What comes out about the company
Nineteen sections, each one answering a question in the sale
Speedio works on big data for lead generation
Speedio positions itself as a big data company focused on B2B lead generation, to support outbound prospecting in Brazil. Based on what it presents publicly, it helps the team segment companies by segment, size, location and revenue, find decision makers by level and department, and get phone numbers and emails for those contacts.
It also offers lists of companies similar to the operation's best customers and integration with CRMs and sales tools. Its strength is volume: many companies and many contacts, filtered and ready for the SDR to start calling and writing.
GoSeek brings the context of each company
Having the director's phone number does not tell you what to say when they pick up. GoSeek takes care of that part. The salesperson enters the CNPJ (the Brazilian company tax ID) and receives the company dossier in 7 to 15 minutes, built from 100 to 500 public sources, with an ICP fit score, a power map and the meeting preparation. The 19 sections are on the dossier page.

|---|---|---|

| Output | List with registration data and contacts, sent to the CRM | Dossier on screen, in PDF and in Excel, written cadence and company history |

Speedio tends to be the better choice when the team's bottleneck is at the start of the funnel.
When GoSeek is the better choice
GoSeek tends to be the better choice when the bottleneck is the quality of the conversation.
How to use Speedio and GoSeek together
The two work well together because they do not compete for the same stage. A common path:
- Speedio builds the target market list and delivers the contacts to the CRM.
- On the Intermediate plan, the team uploads the most promising CNPJs to GoSeek, in a spreadsheet, within the contract's monthly import quota.
- The ICP fit score separates the companies worth an in-depth approach, and the dossier prepares the first contact and the meeting.
Missing leads or missing preparation?
Look at the rate of conversations that become meetings and of meetings that become proposals. If conversations are scarce because there is no one to approach, the problem is the list. If meetings happen and do not turn into proposals, the salesperson did not reach the decision maker or had no timely reason to propose. GoSeek also has, on the Advanced plan, the Market Map, to generate leads by segment and region, but its focus is depth on each company. See how it works and the plans.
What people ask about GoSeek vs Speedio
Does GoSeek have a contact database like Speedio?
On the Advanced plan, GoSeek finds 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. To build large contact lists in volume, a dedicated database like Speedio is a better fit.
Can I upload a list generated in Speedio to GoSeek?
Yes, on the Intermediate plan. All you need is a spreadsheet with one CNPJ per row, within the contract's monthly import quota. Each company gets the dossier and the fit score against your organization's ICP.
Which of the two is better for SDRs?
It depends on the sale. For call and email volume, a lead database like Speedio helps more. For the SDR who opens meetings with large companies, GoSeek delivers the context and, on the Intermediate plan, the written cadence.
Does GoSeek replace the lead list?
No. GoSeek comes in after the list and before the contact, and works alongside the lead database and the CRM your team already uses.
