About Us

We are a startup focused on developing projects and solutions in blockchain for business. We also operate as a software factory in general – where we develop specific, on-demand mobile systems and applications.

IBM is our partner and together we have been developing our flagship project: Notary Ledgers (see here), a blockchain specific to cartorial transactions, a pioneering solution in Brazil.

Other projects in blockchain, in other segments of performance are also being developed by us.

Our team

Our team is senior in having extensive experience in technology projects.

Agility in Deliveries

We are very agile in our projects, which allows us to make our deliveries in a short time.

Project Methodology

We have adopted our own methodology that merges the main positive points of agile and conventional approaches to project management.

What we do

Advice and Consulting in Blockchain

We can contribute to your project! We work from the understanding of scenarios, lifting of requirements to the design and modeling of solutions. We conduct technical trainings and specific lectures on blockchain applied to business.

Development in Blockchain

We develop business software – anchored in blockchain technology. We work from programming to the implementation of projects.

Software Development and Mobile Applications

We also act as a software factory, where we develop specific projects and under customized demands. In the field of mobile applications, we work with Android, IOS, Ionic and other hybrid frameworks.

Notary Ledgers

It is a solution developed by Growth Tech, in partnership with IBM, which allows the execution of services in virtual environments, where all transactions are validated and registered in a private blockchain, formed only by registries – of the most diverse assignments.

It is the ideal solution for integration with legacy systems of companies, that somehow have relation with services and demands that must be realized in notaries.

How it works?


1. The user (individual or legal entity) creates a digital identity ;

2. Choose the service to be performed;

3. Meets the requirements of the service chosen;

4. Generates the draft of the document (eg, Power of Attorney, Deed, etc.);

5. Electronically signs the generated document;

6. Everything is validated and registered in a blockchain.

Common Questions

Who can perform services in the solution?
Any natural persons, legal entities and / or other institutions that wish to carry out the services of account holders.
Is there a need to physically appear at the registry office?
In principle not. The services are carried out in a totally digital way. However, for some rare and very specific reason, it may be that the notary solicits his physical presence at some point.
Can the solution be integrated with other systems in my company?
Yes. The solution architecture is flexible and allows the integration of numerous systems, from different business scenarios.
Why services performed in the solution have legal value?
Because the registries that integrate the network act in the validation of all the transactions carried out, according to their attributions. This fact guarantees public faith and broad legal certainty to the services and acts performed.
How is public faith and the experience of notary offices being preserved in this project?
The solution that is the object of the project will allow all acts to be validated by the notary and its records registered in a blockchain, with the guarantee that the operation will fulfill all the requirements of existence, validity and effectiveness of a legal act, backed, still , by the public faith of the Notary. That is, the public faith of the notaries is being fully preserved, since all transactions continue to be validated and intermediated by these institutions, just as happens in the physical environment. This fact, undoubtedly, guarantees greater legal certainty to the acts and services performed in the digital environment.
What if, for some reason, I need a physical version of the document generated by the solution, how would I have it?
In this case, the notary can take the physical version of the document / act to you, through some logistic service.
How does the Blockchain castorária come to add value to the service of the Notary Public?
Firstly because it is an extremely safe solution, after all blockchain increases the legal security of transactions, mainly because of the immutability of the data recorded in the General Ledger and the fact that the blockchain is allocated outside the internet, as we all know, a of the biggest problems of the day, especially for the corporate world, is the cyber attack.
Then, because it will provide a comfortable user experience – because the service is performed through any computer connected to the solution, anywhere in the world, without the need for physical presence in a notary’s office, nor is it also required that your computer be of great power.
And, lastly, because it strengthens the technological disruption movement we have experienced in recent years, and also contributes to the redesign of the way the Brazilian notaries operate, which will migrate from a traditional position to a vanguard position and aligned with the aspirations of “New society”.
Why is it so safe?
Because records are immutable and protected by one-to-one threaded cryptographic hashes, which forms the blockchain (“block chain” in the literal sense). This means that any attempt to change records will require complex computational effort with the ability to defeat this “tightly bound block chain”. Nowadays, considering the available technological tools and the intellectual resource, it would be an extremely difficult task.
Why should society and the corporate and government segments use this solution?
Minimally, because it is extremely safe, as already commented. Then because it provides a comfortable experience – because the service is performed through any computer connected to the software, anywhere in the world. On the other hand, because it strengthens a strong technological disruption experienced in recent years, it also contributes to the redesign of the Brazilian registry offices, which will migrate from a traditional position to a more modern and aligned with the aspirations of the “new society”.
How does the whole process work?
The first step in performing any service in this solution is the creation of a digital identity in the software itself. The generation of this identity is strict and many validations are made to the competent bodies that issue certain identification documents. The facial recognition of the parts is also done, based on photos taken at the time of the transaction and the photo contained in the identity document.
After this creation, the services are conducted according to the specific requirements of each one, and in the end, the payment is made. The notary and the parties validate the entire process, impute unique digital signatures, which are generated exclusively for the transaction in question.
Concurrently, everything is recorded in a blockchain.
