The easiest way to counter ad fraud.

Spider ‎‎AF is an ad fraud countermeasure tool. We support ad networks, advertisers, and agencies. We have many happy customers across the digital advertising industry.

Flexible and relaxed work environment

We do not believe in micro management. We highly value independent productivity, so you can do your work however you see as fit! As a team, we will think about the process and framework of achieving our goals together, and the independent tasks you are assigned can be completed however you choose to work on them. Our corporate culture ultimately is about doing what we need to do, and going home early. Working long hours is not a virtue here, we focus on quality over quantity.

The average age of our employees is the early 30’s. Since everyone’s age is close, everyone can talk to each other earnestly and freely. We have no dress code, so clothing, hairstyles, nails, and makeup are completely up to you!


Our diverse office is made up of many different nationalities, and we have offices in both Tokyo and Lisbon. We don’t require any Japanese abilities, and welcome overseas candidates looking to relocate to Tokyo (or Lisbon).

Family friendly

Our CEO has 2 kids of her own, along with many other company members having young families. There is a deep understanding for raising children as well as quality time with family. We have paid parental leave, and many events where children are more than welcome to participate.

Our response to COVID-19

During the state of emergency, we come to the office in shifts, so the sales team might come one day, and the customer support another.

We require employees to come to the office at least one day per week, and offer the option to work remotely on other days.
