AI-led qualitative interviews
You set the goal, the hypotheses and the questions. The agent invites your customers, talks to each one over WhatsApp or on the web, accepts voice answers and asks the follow-up questions a form never asks.
About us
About ReveLumi
ReveLumi is an AI qualitative research agent that interviews customers over WhatsApp and on the web, in Portuguese, English and Spanish, and delivers reports with real quotes to any team that needs to hear from its customers.
Product
What ReveLumi does
Conversational NPS
The customer gives a score from 0 to 10, then the agent asks why and digs into the answer. The report shows the score and the reasons behind promoters and detractors, in each customer's own words.
Satisfaction surveys (CSAT)
The same approach as NPS, applied to a support contact, a purchase or a feature. The score comes with a short conversation that explains what drove it.
Ready reports with real quotes
Instead of transcripts, you get findings, customer quotes and recommended next steps. First signals arrive within a few hours, and the report comes in the language you choose.
Real-time human supervision
Your team follows every conversation as it happens. You can approve messages before they go out, take over the conversation or let the agent run on its own. When a customer asks something the agent does not know, it checks with you instead of making it up.
Differences
What makes ReveLumi different
Survey tools collect answers. ReveLumi keeps the conversation going until it understands the reason, and only charges when that happens.
A real interview, not a form
The agent asks again whenever an answer is vague, as many times as the conversation needs. Google Forms and SurveyMonkey ask respondents no follow-up questions, and Qualtrics Conversational Feedback allows at most two per survey.
The conversation happens inside WhatsApp, with voice
Customers answer in the app they already use, by text or voice, and the agent transcribes it. In SurveyMonkey and Google Forms, WhatsApp only carries a link to a form. In Qualtrics, WhatsApp requires XM Directory and Twilio, and the conversation supports only NPS, multiple choice and text.
Analysis in Portuguese, English and Spanish
The report with findings, quotes and next steps comes in the language you choose. In SurveyMonkey, AI analysis (Analyze with AI, Insights and Thematic Analysis) works only on English surveys. In Google Forms, Gemini summaries require a paid Workspace plan and cover up to 200 responses.
Public pricing, monthly plans, no sales team in the way
Plans start at R$647 a month with no lock-in, and you can launch your first study the same day with 5 free credits. Qualtrics and Listen Labs sell by quote, with a demo before use and automatic renewal. Under the Listen Labs contract, fees are non-refundable.
You pay per interview with insight, not per user
ReveLumi only charges for conversations that produced at least one useful answer for the report, and the whole team shares one account. SurveyMonkey team plans require at least three users, with annual billing and a response cap.
Your team can take over the conversation
Listen Labs lets you watch interviews in real time. In ReveLumi, besides watching, your team can approve each message before it goes out or step into the conversation, and chooses that level of control for each study.

Who it is for
Who uses ReveLumi

- Product teams that want continuous discovery without waiting on a researcher's calendar.
- Founders who need to understand why customers do not convert, do not renew or do not use a feature.

- Marketing teams that test concepts, messaging and positioning with real customers before launch.
- Design and UX Research teams that want more interviews without a bigger team.
Team
The team behind ReveLumi
ReveLumi grew out of a problem the founders lived through. In 2025, with AstroLumi, a conversational astrology product, plenty of people were interested and few paid. Joca interviewed users over WhatsApp, running 25 to 30 conversations at once, and found the problem was not usability: people did not understand what the paid plan offered beyond the free version.
The fix increased sales, and the next question was whether an agent could do that work on its own. In April 2026, Joca and Anderson founded ReveLumi. They had already worked together at Conta Azul, as CPO and CTO, and today they are the whole team.
Joaquim Torres (Joca)
Co-founder and CEO
Has worked in digital product for more than 30 years. In 1992 he co-founded Dialdata, one of Brazil's first internet service providers, later sold. He was CPO at Locaweb, Conta Azul and Gympass (now Wellhub) and CDO at Lopes, where he led the real estate company's digital transformation. A computer engineer from ITA, he has written four books on product management and founded Gyaco.
Anderson Borges
Co-founder and CTO
Was CTO of Conta Azul from 2013 to 2019 and of ClickBus from 2019 to 2021, then CTO of Zak and Trela. He started his career at technology companies in Santa Catarina, such as Informant, the company Conta Azul was spun out of. He holds a degree in Information Systems from UDESC.

Frequently asked questions
Frequently asked questions
Does ReveLumi replace a researcher?
No. ReveLumi does the operational work: inviting, running the interviews, transcribing and synthesizing. Deciding what to investigate and what to do with the result stays with your team.
How much does it cost?
Plans range from R$647 to R$3,680 a month, with 40 to 250 credits. You can also buy extra credits at R$21.50 each, valid for 12 months. Volumes above 250 interviews a month go to the Enterprise plan.
Do I need an annual contract?
No. Every plan is monthly and can be cancelled at any time. Access continues until the end of the cycle already paid.
What counts as an interview with insight?
A conversation in which the customer gave at least one answer useful for the report. Unanswered invitations, greetings, acceptances without content and test conversations are not charged.
Why WhatsApp instead of a form?
Because that is where your customers already are, and because a conversation lets you ask again when an answer is vague. Customers answer by text or voice, in their own time, and anyone who prefers can answer on the web.
Does ReveLumi work outside Brazil?
Yes. Interviews run in Portuguese, English or Spanish, and the report comes in the language you choose. Participants answer over WhatsApp or on the web, from any country.
Does the agent say it is an AI?
The agent talks with the name and tone your company sets and does not introduce itself as an AI. If a participant asks, it does not deny it.
How does ReveLumi handle my customers' data?
ReveLumi follows the LGPD and acts as processor of participant data: your company keeps ownership of the data and insights. Data is encrypted in transit and at rest and is not sold or used to train third-party models.
Can I try it before paying?
Yes. Every new account gets 5 welcome credits after verifying WhatsApp, and each study accepts up to 2 free test contacts.
