Public Google reviews written by people who hired the consultancy — with name, company and a link to the source.
Exato supported the structuring of our contractor safety management programme, delivering consistent work, on schedule and with sound technical quality. The initiative helped strengthen our processes and develop our team. I recommend Paulo for his competence and professionalism.
Translated from Portuguese.
View on Google →MSR works in environmental solutions and has relied on Exato as its senior technical back-office for over a year, on demanding projects for large industrial operations. Paulo delivers reports and technical opinions with rare depth, meets deadlines and has a rapport with the environmental agencies that unblocks processes. He is the kind of partner who raises the level of our own service. I recommend him without reservation.
Translated from Portuguese.
View on Google →I work directly with Paulo on MSR's technical demands: scopes and evaluation of laboratory analyses, CADRI permits, SIGOR waste tracking and reports for pulp and paper projects. He is a technically complete and fast professional — he knows the legislation inside out and knows exactly what the agencies require, and he explains the reasoning behind every route taken. That expertise saves a surprising amount of time. I recommend him without hesitation.
Translated from Portuguese.
View on Google →We operate a fertiliser terminal in Praia Grande and needed to structure the entire environmental side: CETESB registration, permitting (LP/LI/LO), technical documentation and operating procedures. Exato has been handling all of it for us — from the registration and the facility report through to CETESB and city hall requirements, including the review of fertiliser storage standards, among them international ones such as the ASTM self-sustaining test. Paulo is fast and technically very thorough. For logistics and storage companies that need to get licensed and operate in compliance, he is the consultant I recommend.
Translated from Portuguese.
View on Google →Exato supported AgroCP on important environmental processes: CETESB registration to obtain a CADRI permit, SIGOR waste registration and review of service contracts. Paulo handled everything with agility, a strong command of the legislation and an excellent rapport with the environmental agencies — complex processes became simple and well managed. I recommend Exato to any industrial company that needs support with environmental compliance and permitting.
Translated from Portuguese.
View on Google →Exato delivered a regulatory feasibility study (permitting, protected areas and water-use grants) for my company. It came with clear costs, timelines and recommendations, within a few weeks and with an executive presentation. The team has a strong command of federal and state environmental legislation. I recommend them.
Translated from Portuguese.
View on Google →Excellent professional! Always very attentive, helpful and extremely competent in what he does. He shows great care and caution, conveying security and confidence. Beyond his technical knowledge, he is always available to clarify questions and find the best solution for the client. He is a complete professional, committed to quality and excellence in service. I highly recommend him to anyone looking for a top-level service.
