Brazil-Based DeepTech Startup Doroth Raises $4.5M to Build Latin America’s First Microfluidic Chip Manufacturing Plant

The Loccus-led round combines private investment and public funding to scale lab-on-a-chip diagnostics for healthcare and agribusiness.

Published

on

Brazilian deep technology company Doroth has raised approximately $4.5 million to expand its molecular diagnostics platform and build what it says will be Latin America’s first microfluidic chip manufacturing plant.

The round was led by Brazilian biotechnology and molecular diagnostics company Loccus. It combines private investment with public innovation funding from Finep and Fapesp.

Doroth will use the capital to expand its research, product development and production infrastructure. The investment is intended to support domestic manufacturing of molecular testing components and make decentralised diagnostic technology more widely available.

Combining Research and Manufacturing

The partnership brings together Doroth’s scientific and product development capabilities with Loccus’ manufacturing infrastructure, regulatory experience and distribution channels across human and animal health.

Loccus CEO Eduardo Araújo said the investment was driven by the complementary capabilities of the two companies. Doroth has experience in research and securing development funding, while Loccus can help move its technology from validation to industrial production and commercial distribution.

The companies plan to develop an integrated Brazilian technology chain covering enzymes, molecular tests, sensors, automated instruments and microfluidic consumables. This approach is expected to shorten the process of moving diagnostic products from research environments into commercial use.

Building a Microfluidic Chip Factory

Doroth plans to construct an automated factory capable of producing up to four million microfluidic chips annually. The chips will contain proprietary embedded reagents used to perform molecular tests.

Rodrigo Gurdos, founder and director of new business at Doroth, said the facility would be the first microfluidic chip manufacturing plant of its kind in Latin America.

The production system will use precision robots to handle lyophilised beads containing dehydrated diagnostic reagents. A delta robot assembly line will assemble the chips without direct human handling, supporting high-volume production while reducing contamination risks.

The facility will also manufacture Doroth’s proprietary enzymes for qPCR, LAMP and Extreme PCR amplification. The company says one of its enzymes can support test results in less than five minutes.

Decentralising Molecular Diagnostics

Doroth develops compact platforms that combine molecular biology, microfluidics, engineering, electronics, optics, automation and software.

Its equipment can prepare samples, extract genetic material, conduct amplification and read results outside conventional laboratories. This could bring molecular testing closer to farms, processing facilities and other locations where rapid results are valuable.

In agribusiness, Doroth’s technology can detect pathogens, microorganisms, genetically modified organisms and resistance genes in leaves, seeds, grains, milk and meat. It can also identify viruses and bacteria carried by insect vectors, including the corn leafhopper and Aedes aegypti, creating applications across plant and public health.

Supporting Brazil’s DeepTech Ecosystem

The transaction forms part of Loccus’ open innovation, venture-building and corporate venture capital strategy. Its Bios programme targets biotechnology, health, agribusiness, molecular diagnostics and the bioeconomy, while Nanos focuses on nanotechnology and advanced materials.

MOA Ventures advised Loccus on the investment structure, while S4 Consultoria advised Doroth during the transaction.

By combining private capital, public innovation funding and industrial expertise, Doroth and Loccus aim to reduce dependence on imported diagnostic components and establish local production capabilities for advanced molecular testing.

Brazilian Startup Plinq Raises $250K in Seed Funding to Expand Background Check App for Women

Led by Spectra Investments, the funding will support Plinq’s mobile app and its move from individual searches to a subscription service.

Published

on

Brazilian startup Plinq has raised about $250,000 in its first funding round, led by Spectra Investments. Angel investors also participated, including Anton Osika, Liana Selles, Fernando Montera and José Gerardo Carrero. The dollar amount is an approximate conversion of the R$1.3 million round announced in August 2026.

Plinq helps women search publicly available judicial records when checking the background of a potential romantic partner. Founded in 2025 by CEO Sabrine Matos, the company plans to use the investment to develop its mobile app and expand its ten-person team.

How Plinq’s Background Checks Work

Users enter a person’s name and phone number, and Plinq searches public sources, including court records and official publications, to compile a report. The company says its web platform attracted more than 60,000 users and processed nearly 85,000 searches during its first year.

Matos founded Plinq after learning of a femicide case in which the perpetrator had faced multiple domestic violence proceedings that the victim reportedly did not know about. The startup’s aim is to make existing public information easier to find and understand before a relationship begins.

Plinq says 10% of the risk alerts identified by its platform relate to domestic violence records. Those alerts reflect information found in public databases; a search result alone cannot establish a person’s current conduct or guarantee someone’s safety.

Mobile App and Subscription Plans

When the round was announced, Plinq said it planned to launch a women-only mobile app in early September 2026 and replace one-off web searches with a monthly subscription. The proposed app includes identity checks using facial recognition. The launch date was a company plan at the time of the funding announcement; the cited report does not confirm that the app has since launched.

Plinq aims to reach one million active users within six months of the app’s launch. For 2027, it has outlined further features, including a way for users to alert nearby women if they feel at risk during a date. It is also considering services for Brazilian women living abroad. These remain expansion targets rather than existing features or user figures.

Brazil-Based AI Startup Nuvia Raises $1.8M to Expand AI Sales Agents Across Latin America

Amador Capital and Nascent led the round, which will support product development and commercial growth.

Published

on

Brazilian startup Nuvia has raised $1.8 million in a funding round led by Amador Capital and Nascent. Existing investor NXTP participated alongside Crivo Ventures, Delusional Capital and investors brought together through Spectra Investimentos. Nuvia plans to use the capital to develop its platform, strengthen its team and expand in Brazil and other Latin American markets.

Nuvia develops AI agents for sales and customer service. Its platform brings conversations from WhatsApp, Instagram, voice calls, websites and email into one system and connects them with customer relationship management tools. The aim is to help businesses respond to enquiries, qualify prospective customers and carry conversations through more complex sales processes.

Building a presence beyond Brazil

Nuvia is focusing on markets where companies handle large volumes of customer conversations, particularly through WhatsApp. Most of its customers are currently in Brazil, but the company also serves clients in Mexico, Colombia and the Iberian Peninsula. The new funding will help it grow its sales and marketing operations as it pursues a wider Latin American customer base.

The startup says its agents can support tasks that extend beyond answering routine questions. In one example cited by the company, retailer Chocolat Du Jour handled approximately 25,000 customer interactions during an eight-day Easter period, with AI agents managing 91% of the conversations. These figures describe that customer’s reported use of the platform, rather than a result Nuvia has demonstrated for every deployment.

Founded in 2024, Nuvia is led by CEO John Paz, a former Brazil general manager at fintech Pomelo. The latest round follows an earlier raise of about $1.7 million, bringing its disclosed funding to approximately $3.5 million. Reports differ on the date of that earlier round, so the total is more useful here than assigning it a specific month.

Brazil-Based EdTech Startup Premia Raises $975K to Expand AI-Powered Learning Platform and Pursue Acquisitions

The company’s first external investment has been followed by its acquisition of Aulapp, extending its reach into corporate education.

Published

on

Brazilian education technology company Premia has raised approximately $980,000 in its first external funding round from an undisclosed family office with interests in education. The investment will support product development, hiring and acquisitions as the company expands beyond its existing school and higher education business.

Premia previously funded its operations without outside investment. Its platform uses AI to assess students’ progress, identify learning gaps and help educators tailor their support.

AI Tools for Schools and Universities

Premia says its platform uses 18 proprietary AI models designed for educational tasks. The technology analyses how students interact with learning materials and provides information that teachers and institutions can use to guide instruction.

According to the company, its products have reached 3.8 million users across 400 Brazilian municipalities and have been used by more than 4,500 teachers. Premia has also reported improvements in student performance, although the figures provided do not establish how much of that improvement can be attributed to the platform alone.

Acquisition Opens Corporate Education Market

Premia said it would use part of the investment to acquire businesses that add products or customers to its platform. It has since acquired Aulapp, an education business serving schools and companies. The value of that transaction was not disclosed. The acquisition makes Premia’s planned move into corporate education a current part of its expansion, rather than only a future objective.

The company also plans to strengthen its commercial and technology teams. Over the next two years, it aims to reach more than 20 million users, expand to 1,500 municipalities and support over 40,000 teachers. Those are company targets, not current operating figures.
