What type of consulting engagement can I expect

We commence our partnership with an initial conversation to deeply understand your product's challenges and the specific issues you are aiming to resolve. Our engagements are typically bi-weekly, during which we present our comprehensive findings and strategic proposals tailored to your objectives. Beyond these scheduled interactions, we maintain an open line of communication through a dedicated Slack or Teams channel, ensuring that your team has consistent access to our expertise and can engage with us for ongoing inquiries and support.
What is your pricing structure?

We'll work together on a month-to-month advisory contract.
What about startups or products that don't have much data yet?

Our clients range from startups to enterprises, and we would be happy to have you on board. Lacking direct empirical data is not a constraint, as we deploy our rigorously field-tested strategies and heuristic diagnostics. These methodologies are designed to accurately evaluate your current standing and to formulate a customized growth trajectory, positioning you for sustained success.
