During 12 months we experienced a 100% growth. It was something new to us. It was very exciting but led to a lot more work too. We had to increase our pricing to stop the customer stream. The ratio cost / onboarding was not good and we were not able to serve properly our customers anymore.
That said, we were able to hire a new Software Engineer in the team and now we can provide better services. We ran an ad-campaign too on niche websites. The ROI was not obvious but we became more visible in our industry.
