Waiting for review / approval from @davesnx.

I'm not completely convinced by the angle tbh. Ahrefs was always using ocaml. Extending it to the frontend isn't a dramatic change or a real shift in the company culture. ocaml was basically present since day one. It would maybe be more accurate while still being interesting to explain that it's possible to bootstrap a company around ocaml and reach $100M+ in ARR, 150 employees, 4000+ servers, leadership in a competitive industry? And maybe do a complete different story focused on the migration to melange?

"Result", "Why OCaml", and "Solution" sections have some overlap, creating some repetition. Maybe one of them should be dropped, or we should create more differentiation?

We could make the style less corporate, to be more in line with ahrefs' identity

Will take another high-level look in terms of tone next week.
