What is a semantic data layer?
It is the layer that keeps your business definitions next to the data. It answers, once and for every query, what counts as a new customer, how CAC is calculated, which orders go into revenue and which channels make up each grouping. Without it, every report uses its own rule and nobody notices. It is what separates a lake that stores from a lake that answers.
Why does an AI need a semantic layer to answer questions about my operation?
Without one, the model reads loose spreadsheets and every platform speaking for itself. It adds up spend from three files closed on different dates, does not know whether a new customer includes someone who bought in the physical store, and returns a generic recommendation along the lines of review your campaigns. With the semantic layer, the same question returns the right number and a specific decision. It is not a better AI. It is the same AI, with your business translated for it.
What is an MCP server and why does it matter for e-commerce data?
MCP is the Model Context Protocol, an open standard that lets an AI assistant query an external data source during the conversation. With the Precisian MCP connected to Claude, to ChatGPT or to your own agent, the assistant queries orders, spend, sessions and inventory on the spot, and gets the number already reconciled and already defined, with the calculation on display. No spreadsheet exports, no copy and paste.
How do I connect my ERP to an AI?
With Precisian, you do not connect the ERP to the AI directly. You authorize the ERP as a source for the lake, Precisian loads the history, reconciles the keys with the other sources and applies the semantic layer. The AI then queries the lake through MCP. This avoids the classic problem of wiring a model straight into the database: it does read the table, but it does not know which column is valid revenue or which orders were cancelled.
How much does a managed data platform cost?
At Precisian, from R$ 3,000 per month, one plan and no setup fee. Everything is unlocked from the start: every connector, open API, MCP server, your whole team with no per-seat charge, a consumption and governance hub, a dedicated data analyst and the lake in an isolated environment. What moves the price is your operation's consumption, that is, data volume, connected sources and requests. Features never move to another plan.
How long does it take to start using it?
Authorizing the sources takes minutes and is the only part that depends on your team. You log in to the accounts you already have and click authorize. Precisian never receives, stores or asks for your password. History load, reconciliation and semantic layer are on us. There is no months-long project, no tool migration and no pipeline for your team to maintain.
Which sources do you connect?
Google Ads, Meta Ads, Google Analytics 4, TikTok Ads, Pinterest, VTEX, Shopify, Magento, RD Station, plus ERP and CRM. Custom connectors are included in the plan, with no separate charge.
Does Precisian replace my BI or my data team?
It replaces the engineering layer nobody wants to maintain: ingestion, reconciliation and modeling. Your BI stays where it is, consuming through the API. Your data team goes back to analyzing instead of fixing pipelines. With the MCP open, several clients have built their own systems on top of the lake, from a conversational agent to a dashboard platform.
Is my data kept in a shared database?
No. Each client has an isolated environment, with no shared database. Data is encrypted in transit and at rest, access is least privilege by role and with MFA, revocable at any time, and every query is logged and auditable down to the data that supported the answer. The data centers where the platform runs hold ISO/IEC 27001 certification. The certification is of the infrastructure, not of the Precisian product.
Do you use my data to train AI models?
Use of client data for training is defined by explicit policy in the contract, never by assumption. Architecture, sub-processors, retention policy and the split of responsibilities are in the full technical sheet, sent on request.
If I decide to leave, what happens to the lake?
You take the whole lake with you. The environment is portable at any time and the exit is planned from the contract onward, not improvised at the end.
Is Precisian useful for companies that are not e-commerce?
Yes. The platform serves e-commerce, omnichannel retail and lead generation operations. What changes between them is the semantic layer, because the metric definitions are different. The rest of the path is the same.
