$100k ARR but not able to scale!

Hello Founders, I need genuine help to scale my B2B Marketing Tech SaaS. We are doing $8k MRR and spending $5k expenses, we are not able to scale. Every month I need to build the runway for next month. We are bootstrap, raised $35k from known angel investor and got few VC’s traction but no luck. I need fund to do PMF and spending major time to build next month runway :(
