‘Very advanced technical knowledge, constructive stance in negotiations, and availability to meet deadlines.’
‘Guilherme Monteiro has very advanced technical knowledge and has a differentiated and constructive stance in negotiations.’
‘Veirano is a firm that truly seeks to understand the client's needs. The assistance is unique and personalised; they seek to understand the client's stage and create a decision matrix on the impacts of each decision. They are quick to respond and work alongside the client.’
‘What I like most is their professionalism, which is praised even by the other side of the negotiation.’
‘I would like to highlight Guilherme Monteiro as one of the best lawyers for startups, regardless of their stage. The way he identifies the nuances of the contract, reports them to the client, and explains them during the negotiation makes him unique. In addition to being an excellent professional, he is a very nice person and his team has done an excellent job, especially Luciana Maffrei.’
‘Attentive, competent, and dedicated team. They are always ready to help and are attentive to deadlines. It is a relationship of great partnership and trust.’
‘Guilherme Monteiro is always attentive and concerned about the client. He follows through every detail and always seeks careful and creative solutions.’
‘Luciana Maffei is attentive, available and efficient.’
'The biggest difference for our company's scenario is that they offer a very advantageous model for early-stage startups without enough capital to cover law firm costs... the model with no initial costs in exchange for a portion of future fundraising is very good.'
'Our contact point is Daniel Malatesta, and he has been very helpful and attentive in supporting us. He has gone above and beyond to help us.'
