How We Work

Scrum Development
We embrace Scrum as our framework to foster agility, collaboration, and continuous improvement. Our Scrum team includes a Certified Scrum Product Owner (CSPO) and a Certified Scrum Master (CSM), ensuring a structured yet adaptable development process.

Domain-Driven Design
We prioritize Event Storming as a core practice to explore and understand complex business domains. By mapping domain events, we gain a shared understanding among engineers, product managers, and stakeholders, allowing us to identify key business processes and constraints early. This event-driven approach helps us design systems that accurately reflect real-world behaviors and evolve alongside our business.

Our Culture

Product Driven: We focus on solving our users' issues, not just writing code. Our discussions are always centered around our customers' needs. We value quick iterations and rapid feedback loops to continuously refine and improve our product.
Creative + Innovative: We encourage our team to go beyond solving our users' immediate problems. Until now, our best features have come from implicit or hidden information within user feedback. We look at feedback from many angles to discover our users' underlying needs and produce compelling features that achieve high user satisfaction. To support rapid feature development, we have a solid testing infrastructure.
End-to-End Ownership: Every team member can shape the product and contribute to its success. Our engineers practice end-to-end ownership in their work, from design to implementation and monitoring. We believe in continuous improvement, proactively refactoring and enhancing our architecture to keep it scalable and maintainable. Ultimately, we take ownership not just of the code, but of the impact we deliver to users.
Documentation: We believe that well-written documentation is a reflection of clear thinking. Whether it's API specs, architectural decisions, or onboarding guides, we document knowledge to ensure clarity, alignment, and long-term maintainability. Clear documentation empowers our team, accelerates onboarding, and enables us to scale efficiently.
Blameless Retros: We value continuous improvement of processes, creating a supportive and open work environment. We prioritize learning and improvement over blame. We always seek to enhance our processes through honest and constructive discussions.

About amptalk

amptalk's mission is to maximize the time people spend with each other and to create opportunities that did not exist in the world until today.

They aim to create a society where people can live more efficiently by accomplishing tasks that humans alone can not do.

amptalk develops and markets products that allow users to focus more on high-level sales activities and accelerate sales generation through the use of voice recognition and various AI technologies. They hope to help create more opportunities in the world by developing these efficient and effective sales tools.

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.

Why amptalk - "An exceptional team with a deep understanding of pain points"

amptalk is a product-driven team that respects each other and is committed to excellence. They are a team of people who respect each other and are committed to being the best. They work in a diverse environment of nationalities and languages, unlearning from past experiences and sometimes using them as ideas to provide innovative solutions for their users and to make the world a more amazing place. amptalk focuses on creating products that solve problems by removing the focus from unnecessary and uninspiring tasks.

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.
