- Recommendations - Ask in your network
Filter by:

- Availability for calls
- First impression of the team

Avoiding Common Mistakes
Mistake 1: Unclear Requirements
Problem: "We want an app like Uber, but for X"
Solution: Invest in a discovery phase. Document requirements in user stories with acceptance criteria.
Mistake 2: Only Looking at Price
Problem: Choosing the cheapest agency and having to fix things later.
Solution: Evaluate total value, not just hourly rate. Faster, higher-quality delivery saves money long-term.
Mistake 3: Too Little Involvement
Problem: Handing over the project and waiting for the result.
Solution: Stay involved. Participate in sprint reviews, give timely feedback, be reachable for questions.
Mistake 4: No MVP Approach
Problem: Wanting to build everything at once.
Solution: Start with an MVP. Learn from the market. Iterate based on real feedback.
Mistake 5: Missing Maintenance Planning
Problem: After launch, no one is responsible for bugs and updates.
Solution: Plan a maintenance budget from the start (typically 15-20% of development costs per year).
