amptalk’s mission is to create "a world where people are empowered around conversations”.

They are creating a world where each and every person is empowered by using software to streamline and eliminate unnecessary tasks, and by using software to do what people have been unable to do until now. Conversation accounts for a large percentage of people's lives in society, and the concept of negotiation is not only used in business negotiations, but also in all aspects of human life, including romantic relationships. Yet, many aspects of conversations have not been given much opportunity to be reevaluated. amptalk presents such opportunities through developing software to create a world in which each individual is empowered and all users are happy.

MISSION, VISION, and VALUE

MISSION - Maximize the time people spend with each other. The responsibility of sales and other customer-facing positions is to determine how much time they can spend with customers in a higher-quality manner. amptalk will unlock sales operations to maximize the amount of time spent talking to customers, and minimizing all the peripheral operations and communication barriers that are preventing the forementioned.

VISION - To create opportunities that didn't exist yesterday. The world is losing countless opportunities due to the inefficiencies of conversations and human behavior. By streamlining all sales-related tasks, such as training and administrative work, amptalk will create opportunities that didn’t have the chance to exist before.

 

VALUES

GET IT DONE

The best people are those who take initiative and execute. Ideas and theories alone accomplish nothing. Don't be a critic. Act first, instead of overthinking.

 

EXTREME OWNERSHIP

Let's stop drawing lines based on roles or titles. Break down barriers and treat everything as your own responsibility. Treat problems happening elsewhere as your own, and step outside the box to challenge yourself if it helps the team move forward.

 

EXPLORER

In a rapidly changing world, we applaud those who have a proactive spirit of exploring and taking on new challenges, and are always eager to try new things.

 

GIVE FIRST

Do good without expecting anything in return. Acting bases on short-term gains alone won't lead to real change. Put yourself in the shoes of society, our customers, and others, and act on what truly matters.
