Eight months in and hitting thirty grand a month - that's solid work. What stands out to me is that you didn't just jump into pure marketing services. Building a SaaS alongside strategy consulting gives you two different levers: one recurring and scalable, the other high-touch and relationship-driven. It's like having a garden and a farmers' market stall - you're not reliant on one harvest.
I've seen a few people in the thread chase ten thousand as a goal, but your trajectory shows that if you pick the right niche (in your case, SaaS development with advisory), the revenue ceiling shifts. The sixty grand mark by year-end sounds ambitious but doable if your product market fit holds.
One thing I'd gently point out - you mentioned "we advise our customers on strategies." That's actually a marketing service, even if you frame it as advisory. Could be worth formalising into a paid consulting tier or workshop. Keeps the expertise visible while the SaaS scales.
