Our Journey
2015
David Simões, a Portuguese national and future founder of Sounds Good Agency, moved to Brno and started working at the development agency Ents. Just a year later, he began leading their e-commerce department with a focus on Shopify solutions.
2016
We became the first developers in the Czech Republic and Slovakia to receive the Shopify Experts certification. Most companies are merely Shopify Partners — a status anyone can obtain by registering for the Shopify Partner program. The Shopify Experts certification is awarded only to agencies that have been individually vetted by Shopify directly.
2018
Sounds Good Agency is established as an independent development company specialising exclusively in Shopify. We earned 80+ reviews with an average rating of 5/5, and built a Fakturoid integration following the introduction of the EET (Electronic Sales Records) act. We also became one of the few Shopify Experts worldwide with access to the Shopify Hosted Payment SDK, which enabled us to build integrations with GoPay and ComGate.
2022
Over the preceding years we had the opportunity to work not only for over a hundred e-commerce companies from around the world, but also for well-known local brands such as Mana, Okay.cz, Ledvance, ETA, and GoPay.
This year also brought a moment where David had to choose between family and business. Due to illness in the family, he decided to step back from the business and sell the agency to two colleagues — Robin Navrátil and João Antunes.
2023
David decided to exercise his buyback option and reacquired a 30% stake in the agency. Shopsys, the domestic leader in custom e-commerce development, acquired Sounds Good, the local leader in custom Shopify development.
This strategic move allows us to expand our service portfolio, increase accessibility to a broader segment of the e-commerce market, and accelerate growth. Together we are able to offer unique expertise in both custom development on the Shopsys Platform and custom development on Shopify. Read the full article.
2024
Sounds Good, Shopsys, Reservio, Smartsupp, and Survio join forces to form the ABUGO group. This allows us to offer a broader technology portfolio under one roof. The combined annual revenue of the newly formed holding is approaching three hundred million Czech crowns. For Sounds Good, this means shared know-how with international reach and access to AI innovations. Together we can simplify online shopping and provide our clients with a wider range of products and expertise in one place.
Our Values
Expertise & Client Obsession
We have the deepest Shopify expertise and strive to convert it into success for our clients. We often don't need to explore dead ends — from experience, we know which path is best to take. Our clients' successes are what we love to show off.
Enterprise-Ready, Yet Accessible to Mid-Sized Online Stores
We have years of experience with enterprise clients, but we equally enjoy working with ambitious mid-sized online stores. There is no "B-team" with us — the same attention, effort, and seniority of team for projects of any size.
Transparency, Honesty, No-Bullshit
You have full visibility into our kitchen: we open Jira to you, you can participate in planning and retrospectives, and you are kept continuously informed about budget usage. We want to discuss everything openly — if something doesn't make sense, we'll say so directly and try to propose a better approach.
Stability, Security, Long-Term Partnership
A custom online store is not a commodity; it is a partnership for years. We build a financially healthy company with low staff turnover. We are part of Shopsys and the ABUGO group — a foundation that brings capacity, specialised teams, and continuity you can rely on for the future.
