Dynadok: Revenue, team and how it was built

Each row shows the evidence grade and the source numbers from the list at the end of this page. The grades are explained in How Aiolum verifies.

How to read this table: grade D is a figure that only the company stated, without an outside check. Grade C is a statement by the company or its customers about facts other than money. Grade X was calculated on this page. Quotations in Portuguese are followed by an English translation marked (translation). No value is grade A or B.

Dynadok sells by quote. A one-time setup fee pays for its project team to design the document flows and rules and to go live, which takes one to four months. After that, a monthly subscription buys an allowance of pages processed by the AI, which expires monthly or yearly; the price per page falls as the volume grows. There is no charge per user or licence. Modules such as anti-fraud and automatic issuing of certificates can cost extra. The one figure on the site is an example from the company's savings calculator: R$12,800 a month for 20,000 pages a month, about US$2,359 at the Federal Reserve H.10 rate of 30 October 2026 (5.4252 reais per US dollar). It is a scenario, not a list price.

Four causes, in the order they mattered. Each one is a reusable lesson.

How it was built

These details come from the company's site and the launch article. They are grade C. No source names the AI model providers. [7, 3, 5, 6]

• A combination of large language models, advanced OCR, computer vision and retrieval-augmented generation (RAG, where the model looks up stored reference text before it answers), according to the company's FAQ.
• At launch the company described IDP with machine learning, generative AI and natural language processing, and contrasted it with robotic process automation (RPA), scripts that copy what a person clicks.
• Configurable checklists and rules per document type, and cross-checks between documents and with the customer's systems.
• A portal where suppliers, students and candidates upload documents, with expiry tracking and renewal reminders.
• Automatic issuing and lookup of 27 official certificates and registers, such as federal tax, labour debt and FGTS certificates, directly at the government source.
• A REST API for integration with the customer's ERP, and a project team that sets up each customer over one to four months.

Three companies in our database of failed startups tried to turn paperwork or contract checks into software and failed. The values below are from that database and are not independently verified.

The failed startups come from our database of 1,749 dead startups, retold here in our own words. Its entries are AI-assisted summaries of public sources, so these cards carry no evidence grade.
