Lemit Tecnologia: What It Is and How to Protect Your Data

If you searched for Lemit Tecnologia after receiving a persistent call or seeing that name in your company's data report, this guide is for you. Lemit Tecnologia is a Brazilian B2B data enrichment company — and understanding what it does, whether it's legal, and how to protect your information has become urgent in 2026. Here are the facts, the legal basis under the LGPD, and what your business can learn from this case.

TL;DR

  • Lemit Tecnologia da Informação Ltda (CNPJ 29.015.808/0001-24, founded in 2017 in São Paulo) operates in B2B data enrichment, VoIP, and SMS.
  • It became a search trend due to complaints on Reclame Aqui about calls and data requests — the company denies calling consumers directly and attributes this to its LEMIT VOX division.
  • Data enrichment is not illegal, but it depends on a legal basis under the LGPD (legitimate interest, Art. 7, IX) and the balancing test required by the ANPD.
  • You have the right to request deletion of your data; your company should prospect through official channels with a clear opt-out.

What is Lemit Tecnologia

Lemit Tecnologia da Informação Ltda is a São Paulo-based company (CNPJ 29.015.808/0001-24), founded on November 7, 2017, with headquarters on Rua Amaral Gama in the Santana neighborhood. According to the Brazilian IRS (Receita Federal), its main activity is registered as “collection activities and registration information” — meaning the core of the business revolves around data on individuals and companies.

In practice, Lemit positions itself as a specialist in data intelligence. Its portfolio combines three fronts: data enrichment (completing records with phone, email, partners, and revenue), VoIP — branded as LEMIT VOX — and SMS broadcasting. All aimed at the B2B market, for sales and collections teams that need to locate, qualify, and contact leads faster.

It's important to separate what the company sells from what the public feels. For buyers, Lemit is a commercial productivity tool: less time prospecting for contacts, more time closing deals. For someone receiving a call without knowing how their number got there, the perception is quite different — and it's precisely this friction that put the brand on top of Google searches in Brazil.

The spike in interest for Lemit Tecnologia didn't come from a product launch. It came from complaints. On Reclame Aqui, consumers throughout 2026 report persistent calls, unknown numbers, and requests to confirm sensitive information. In January and March 2026, this type of complaint appeared frequently on the company's page.

Lemit's official response is straightforward: it states that it does not make calls directly to consumers. According to the company, the contact is made by clients using the LEMIT VOX technology division, a VoIP solution that connects businesses and consumers. In the first half of 2026, the company maintained an average response time of about 20 hours on the complaint platform — a sign that it monitors the feedback.

This mismatch — the company providing the infrastructure versus the client making the contact — is at the heart of the problem. When data circulates through multiple hands, the data subject loses traceability and no longer knows who is on the other end of the line. And that's when the conversation shifts from being about a specific brand to being about how Brazil handles personal data in 2026.

How B2B data enrichment works

Data enrichment is the process of taking an incomplete record and filling it with information from other sources. You only have a CNPJ? Enrichment returns the company name, estimated revenue, partners, phone numbers, emails, and decision-makers' titles. It's what turns a cold list into an actionable list for the sales team.

Suppliers in this market typically offer a similar set of features:

  • Contact validation — remove duplicates and outdated records from the database.
  • List enrichment — add revenue, corporate structure, and decision-maker titles.
  • Market calculation — estimate TAM, SAM, and SOM to refine the ideal customer profile (ICP).
  • Segmentation — filter by technology used, company size, industry, and location.
  • Visitor identification — reveal who anonymously visited your website and became an opportunity.
  • API integration — deliver all this into your CRM in real time.

For the sales team, the gain is obvious: fewer hours wasted chasing contacts, more focus on selling. The risk is also obvious: if the data source lacks a legal basis, efficiency becomes a legal liability. Enriching a business phone that the company publishes on its own website is one thing; calling someone's personal cell phone without authorization is entirely different.

Data enrichment and the LGPD: what the ANPD says

Here's the question everyone asks: is data enrichment legal? The short answer is: it can be, if there is a legal basis. The Brazilian General Data Protection Law (LGPD) does not prohibit enrichment, but it requires a valid justification for processing personal data.

The most commonly used basis in this scenario is legitimate interest (Art. 7, IX). The ANPD (National Data Protection Authority) published an Orientation Guide detailing how to apply it. The central point is the balancing test: the company must document why its commercial interest outweighs the impact on the data subject's privacy — and it can never use this basis for sensitive data, such as health or biometrics.

Another important piece is Art. 7, §4: data manifestly made public by the data subject may be processed for legitimate purposes. This supports the enrichment of business emails and phone numbers disclosed on the company's official website or in public sector registries. You can check the legal basis directly at the source in the ANPD Orientation Guide on Legitimate Interest.

Situation Probable legal basis Allowed?
Business email on company website Public data (Art. 7, §4) Yes, with legitimate purpose
Business phone in public registry Legitimate interest (Art. 7, IX) Yes, with balancing test
Personal cell phone without consent High risk
Sensitive data (health, biometrics) No, via legitimate interest

The bar, therefore, exists and is documented. The problem arises when it is simply ignored in the name of volume.

Your data appeared at Lemit? How to request deletion

If you've been contacted and suspect your information is in an enrichment database, the LGPD gives you concrete tools. The data subject has the right to object to processing based on legitimate interest and the right to request deletion of processed data.

The practical path is this:

  1. Identify the controller. Ask the caller where the number came from and which company is behind it. If the answer points to LEMIT VOX or a similar service, the trail starts there.
  2. Contact the DPO. Every company that processes data must designate a data protection officer channel. Send a formal request for deletion and objection.
  3. Document everything in writing. Email creates evidence. Keep dates, protocols, and the response received.
  4. Escalate to the ANPD. If the request is ignored, you can file a complaint with the National Data Protection Authority.

Remember: the opt-out must be clear and functional. An opt-out that doesn't work is, in itself, an indication of irregular processing. For those doing prospecting, offering this exit is not a courtesy — it's a legal obligation under the law.

The other side: how to prospect without becoming a complaint

Maybe you're reading this not as someone who received the call, but as someone who needs to sell. The lesson from the Lemit Tecnologia case applies to both sides: you can prospect actively without turning your brand into a public complaint.

The practical rules for 2026 are straightforward:

  • Use business data, not personal data. Institutional emails and phone numbers publicly disclosed have a stronger legal basis than a partner's personal cell phone.
  • Document legitimate interest. Perform the balancing test in writing before the campaign. If you need to justify it to the ANPD, you already have the document ready.
  • Offer opt-out in every message. Visible unsubscribe, identifiable sender, and a reasonable relationship between the product offered and the recipient.
  • Respect frequency. Calling ten times in one day is not persistence, it's harassment — and that's exactly what generates complaints on Reclame Aqui.
  • Prefer channels the client chose. Those who opt to receive your message convert more and complain less.

Aggressive prospecting with dubious data delivers volume in the short term but destroys reputation in the long run. The model that survives the LGPD is permission-based: the client accepts being contacted, and each step is documented and auditable.

Official channels: the path Agathas Web recommends

At Agathas Web, we defend a simple thesis: good contact is contact the client authorized. Instead of buying lists and blasting cold calls, consistent returns come from official channels, with real opt-in and end-to-end traceable history.

The best example today is WhatsApp. The Official WhatsApp Business API allows you to chat with those who opted to talk to you, within Meta's rules, without the blocking risk that haunts those using irregular methods. I've already explained the difference between the regular app and the official version in WhatsApp Business App vs Official API, and showed how to avoid business number blocking when message volume grows. If your cost per message is high, it's also worth understanding the hidden markup of platforms.

The difference in mindset is huge. Data enrichment looks at a contact as a line in a spreadsheet. The official channel looks at a contact as someone who raised their hand. One generates complaints; the other generates relationships.

Data technology is not a villain — it's neutral. What decides whether it becomes an asset or a liability is the choice between efficiency at any cost and growth with consent. And in 2026, with the ANPD more active, this choice is no longer just ethical: it's also financial.

Conclusion: data is responsibility, not just opportunity

The Lemit Tecnologia case is a snapshot of the moment: Brazil discovered the commercial value of data before digesting the rules on how to use it. Data enrichment is a legitimate tool when anchored in a legal basis, balancing test, and functional opt-out. It ceases to be when the data subject becomes just a dialed number without context.

If you received the contact, you now know how to request deletion. If you sell, you know how to prospect without becoming a negative headline. And if you want to build a service channel that respects the client and still converts, Agathas Web can help you set up that structure with the Official WhatsApp API and automations that only talk to those who want to listen. Start with permission — the rest is consequence.
