Working with Asper Brothers, led by Mike and Pawel Jackowski, has been an exceptional experience for us at Nursety LLC. Their team helped us take our initial concept and turn it into a well-structured technical plan, ultimately delivering a fully functional mobile app and backend platform for our MVP.From day one, the Asper Brothers demonstrated impressive technical expertise, strategic insight, and project management skills. They guided us through the entire development process—refining our MVP to fit within our budget and timeline while maintaining high quality and innovation.With their support, we successfully launched our MVP and completed three development sprints within our first year. During that time, the team helped us implement key new features such as text notifications, mobile announcements, and AI enabled user survey creation.The value Asper Brothers delivered has far exceeded our expectations. They’ve proven to be reliable, insightful, and genuinely invested in our success. We’re excited to continue working with them as a trusted technology partner.— Adrian Marsh, Co-founder, Nursety LLC

We've been working closely with Asper for almost two years and I can't rate them highly enough. The reality with any agency relationship is that success depends on mutual fit - both the agency being right for you and you being right for them. With Asper, issues are incredibly rare, but what matters most is that when challenges do arise, we work together 'like brothers' to set things right. The true test of any partnership is how a business handles things when they go wrong, and in this regard, Asper consistently exceeds expectations.

We partnered with HS on few projects. Started with small test work to see how things would go on a small scale. During this test we were able to talk with mgmt team (both PM and Top mgmt), CTO and few tech team members and we liked what we heard. Team was really focused on suggesting to us different options and describing pros and cons of each. So we proceeded to a bigger project planning. It's mid the journey and so far we are happy with the approach and quality, especially when some tension comes up with bugs or anything - we're able to figure out the win win, and we receive reasonable outline of why this or that happened.

One of the worst software companies we’ve ever worked with.If you're considering working with them, read this first:They never delivered the product they committed to — after getting paid, they vanished, leaving us with nothing.Their business model seems to be: drag out projects endlessly, then charge extra to fix their own technical mess.Endless bugs — every fix introduced more problems. It was a never-ending cycle.The product never worked at any point, not even partially.They talk a lot about “best practices”, “scalability”, and “clean architecture”, but:Their code, reviewed by external experts, was a disaster.Functions with over 500 lines, no automated tests, no proper error handling, and no security.Critical security flaws:Users could access and modify other users’ resources — a massive breach of trust and privacy.Ultimately, it was a complete waste of time, money, and energy.When challenged, they were arrogant and even mocked us instead of taking accountability.🔴 Avoid them at all costs. If you value your time, your budget, and your sanity — don’t even call them.
