Krsnaa Diagnostics – what is the diagnosis?

I have recently started studying this co and there a re a few things I could not wrap my head around –

1. How much did the Promoter dilute to PE in 2015 that his stake came down to 31% Pre IPO?? Seems a little off to me given that Vijaya for instance, diluted to Kedaara and yet promoters held 54% post listing
2. Co began in 2011, raised PE money in 2015 – which means within 4 years of beginning operations, they were technically qualified to bid for large B2G Contracts (these often come with a minimal technical qualification rule)
3. co was doing 40-50 crore of rev till 2017, what exactly happened between 2017 and 2019 that revenues tripled, co filed IPO Papers all in the same period ? (this should be the quickest that a startup has began operations and filed for IPO – 8 years)
4. ZERO management bandwidth when it comes to this space. Apart from the COO who is ex Metropolis, I dont see any top management guy who has any experience in the healthcare space. Infact, Yash Mutha has spent 15+ years working at CS backend + top 4 accounting firms. Wonder what experience does that lend to in managing such a complex, government oriented biz
