Security first approach

Our solution is SOC2 Type 2 compliant, a crucial security policy for handling sensitivecustomer data. It allows the storage of Protected Health Information (PHI) and Personal Information, fully compatible with GDPR and HIPAA regulations.

Here‘s a break down of our process

Design sprint

9 out of 10 startups fail, because they fail to skip the competition

Design Sprint is an effective methodology purpose-built to address the changing needs of agile development. Through a week of design sprint, we carve out a product strategy like Calendly's "easy scheduling" or Superhuman's "Fastest email experience" for your vision. We then proceed to develop, test, and iterate on the app prototypes.


UX Design & Development

Cutting-edge UX, auto-generated UI, and modular backends enable us to develop your app at blazing speed

Over the past 4 years, we have laid the building blocks of an effective assembly line that allows us to develop apps within a 2-week timeframe.


Launch & Deploy

Build in days, ship to millions at a fraction of the average hosting costs

Startups spend a considerable portion of their runway on product development with limited iterations. Our streamlined product delivery process, combined with our automation tools, enable you to build, launch an grow at a fraction of the average cost.

Frequently asked questions
No upfront payment. How does it work?

Pay at the end, after the launch of the app. If we don't launch your app in 4 weeks, we will work for free until we do launch, in case you would like to continue working with us still.

When can you start working on our project?

At the start of each month, we kick off a new project.

Why is there limited seats?

When committing to a new project, our entire attention is dedicated to its success above all else. Taking on multiple projects simultaneously forces us to divide our focus, which compromises the likelihood of achieving success.

How do you guarantee 4 week delivery?

We follow our own blueprint, which is the result of years of designing, developing, and launching apps. We call it an assembly line. Over the past four years, we've developed all the building blocks to design, develop, and launch apps within 4 weeks. We're so confident in our execution that we offer a no-upfront payment guarantee to all of our clients. You only pay after successful delivery.

Who do we work with?

You work directly with Behrad and Omid throughout the 4-week process. You will have daily touch bases with us through a direct Slack channel and participate in multiple workshops.

I have negative experience with other dev agencies. How are you different?

We're serial entrepreneurs, passionate about building scalable products. We accept only one client per month and dedicate 100% of our focus. We don't charge a retainer fee; you only pay us upon successful delivery. Many of our current clients are returning, a testament to our commitment to the success of your enterprise.

How do I translate my idea into a MVP?

We leverage design sprint methodology, which is a proven and effective process to design and test app concepts. This process was initially developed at Google Ventures and is now a widely used method to arrive at MVP concepts. Behrad has conducted many design sprint workshops in his career.

How does Development work?

Through the past 4 years, we've created a modular low-code platform focused on scalability, security, and data protection. Our numerous customizable modules enable us to deliver solutions swiftly, in weeks instead of months. We offer everything necessary to develop your digital products, granting you full ownership of every line of code.

How do you guarantee security & scalability?

Our solution delivers flexibility, speed, and power, providing you with absolute control over your infrastructure. You can scale your solutions unlimitedly, regardless of the number of users or the volume of data. Our platform is modular and containerized, allowing indefinite scaling to meet your growth needs. From day one, we adopt a composable architecture with robust security features and granular permission controls to protect every bit of your critical data. Your data is securely encrypted both at rest and in transit, safeguarding against unwanted access and breaches. Additionally, we offer a comprehensive audit module out of the box, enabling you to track all activities on your solution..

How do you ensure data security?

Our solution is SOC2 Type 2 compliant, a crucial security policy for handling sensitive customer data. It allows the storage of Protected Health Information (PHI) and Personal Information, fully compatible with GDPR and HIPAA regulations. Moreover, all customer data is encrypted at rest with AES-256 and during transit via TLS. Thanks to our role-based access control, you can keep track of who has access to what at any given time.

Do you have a DPA (data protection agreement)?

We build your products with heavy focus on scalability and data protection. Since every line of code is your IP, we opt for hosting the solution on your cloud provider with us being here to support after launch to maintain your solution. Therefore we typically do not offer a DPA, only if you prefer to host the solution with us.

How do you manage DDoS attacks?

Our solution has out-of-the-box features to enhance security & data protection. More specifically, we offer protection against DDoS  attacks, mitigating resource abuse and preventing unexpected costs.

What if my app idea is complex? Can you still launch it in 4 weeks?

During the first week workshop, we will prioritize and focus on the most important product capability first. Many successful businesses have been built on delivering ONE product capability like no others. Calendly, Doodle, Docusign, and UserTesting are some of the prime examples. They all began by focusing on doing one thing exceptionally well.

What if I need additional features after the initial launch?

We offer you flat retainer and each month, we will launch an additional feature for €3500/month on a 12-month minimum engagement contract

Can you help apps with existing customers and complex architecture?

Yes. We would offer you a customized offer depending on the scope of the project. Please schedule a discovery call with us, and we will decide whether your project is the right fit.

What if what you build won't get us to revenue?

Entrepreneurship is a game of taking calculated risks. There's always a risk of not succeeding. Your odds of achieving $100k ARR working with us are higher compared to any other scenario. We narrow down your focus around a single product capability that your target market would want now. With our exceptional execution capability, you can present your offer to them in as little as 4 weeks. You will quickly learn whether your core offering can generate revenue or if you need to pivot. This is already a significant advantage compared to typical scenarios where you might have to wait 6 months to enter the market.

We can’t afford 20k but we would like to work with you. Can you still support us?

Considering how long and how much you need to invest in a typical scenario to launch your app, 20k is already a great offer. On average, a startup costs about 7.5k Euro per month to assemble a development team, and it typically takes them 6 months to launch their app. That's already 25k saved for you, We also offer an additional 7.5k in bonuses. Plus you get to tap into our years of experience in developing and scaling products. Experience + execution = success.

Where's your company registered?

We're a German company operating under the legal structure known as GmbH. This structure is commonly used for private companies in Germany and Austria. GmbH is analogous to the Limited Liability Company (LLC) in the United States.

Do you have business liability insurance?

We are covered for financial and business damages caused by our work, up to €500,000.

Where is your team based?

50% of our team is based in Germany; the rest is from France, Japan, Mexico, Brazil, Turkey, England, and Iran.
