Be careful with advice like this. You don't know if the company has yet succeeded. A lot of it is quite logical but at the same time many things are an anomaly e.g the tool launched and closed fundraising within a short period of time. That's not always how it works out. Just because first commit to funding was 3 months doesn't mean you'll experience the same thing. I struggled for 4 years alone on an OSS project before raising funding. Hiring people, defining the product and executing was even harder. A person's experience only tells you what worked or is working for them or lessons they learned, it can't be cookie cutter fitted to your own journey.
