sentiention™

Firm

sentiention™ is a sourcing and venture practice run from the European front and executed on the ground in Asia. Its founder, Pierre Blanquett, spent fifteen years on both sides of the table, eight of them in Shanghai and two in Guangzhou: half as a corporate buyer for BMW, Nielsen, Kantar and NetEase, half building the operator setup that supplies brands like them. The firm is registered in Lüneburg and sources materials and electronics, enters markets and builds ventures for its clients, and it runs its own ventures, Nordling Outdoor and TerraLinen among them, on the same system. The buyer-side eye stays.

Record

Expertise is a utility, not a secret. sentiention™ publishes its working knowledge as open reference, and this platform is the standing record of one field, Battery, read across Chemistry, Format and Safety. It is written for the buyer, the founder or the product owner who has to decide, so every entry starts from the vocabulary that reader actually meets, landed cost, certification, tolerance, lead time, and works toward a decision that can be acted on. Where the firm has a number it names it and does not explain it: a China entry takes 18 to 24 months, and three days as a visitor beat three weeks at a desk.

Method

The record is written the way the firm works, from public sources and from its own sourcing work, with LLM assistance in the drafting, and it is held to the rule the firm applies to a quote: name the number, never invent one. An entry says what can be verified and adds nothing to sound specific, and where the firm does not know, the entry says less rather than more. Every entry is published to be checked, not believed: where a number, a rule or a standard decides a purchase, verify it against the current text and your own audit before committing volume.

Correction

A record that cannot be corrected is not a record. An entry found wrong is corrected in the entry itself, not defended and not annotated beside. Say so through the intake, naming the entry and the line, and the same 24 hours apply.

Intake

Reading the record asks nothing of the reader. When a project is live there is one intake, at sentiention.com, and this platform hosts no form of its own. Send the brief: what is being sourced or built, the volume, the market and the date it has to exist by. A person answers inside 24 hours, and the first answer is a scoping, not a pitch.
