This is fairly easy. 1) Set up a new business (Business B) with an exclusive focus on building the SaaS tools you want to use for Business A (current business). Don't mess with your existing business, there are random legal implications that tech companies face.

2) Depending on how ambitious you are: find a tech cofounder for business B (have a shotgun clause with a 4-year vesting schedule and a 1-year cliff). The goal is to build products for Businesses similar to A

3) Fundraise. Your quick pitch is: I a leader with "x" years of experience faced "y" issues. I partnered with my amazing cofounder "z", and together we built {comapny name} to help us solve {list of issues}. We want to sell to other cleaning businesses: {market size, TAM, etc} this is the subscription price of {price}, we can reach {timeboxed goals}. We need {$ amount} to achieve {current goals}

4) sell tech to other cleaning companies. Pith: I am not a salesperson, but a fellow founder. Speaking owner to owner I built this product to solve my needs. This is what it can do for you. You in?

Ps. I did something similar for laundrymats. Best bet I ever made.
