Ask HN: Books recommendation for scaling a SaaS from 2 to 10 mill ARR?

Hey,

Hope you all had a good year and a better one will come next.

We launched 5 years ago and we kept the business bootstrapped and small, more like a lifestlyle business with 10 employees.

We have a high profit rate and we're ready to scale to the next level. However, our growth rate is stalling due to churn catching up and new solid competitors entering the space.

Any books or learning materials tailored for SaaS in this situation: scaling a product in an increasingly competitive market where growth staled.

Thank you and happy new year!
