Congrats on the new offer! I’m in a similar situation as you. My company pays me well, but they are not huge fans of “Fancy ass tools and software” either.
I think is possible to sales without a stack of tools. However, it will be more difficult. I personally invest with my own money on these depending on their ROI (return on investment).
For example, I use seamless.ai to get prospect contact information. That tool has changed my game! I love it! I close more deals, and it makes my job easier, so I invest on it with my own money.
You would just have to determine which software gives you the best ROI. Follow the 80/20 rule to save money. Ask your self, what is the 20% of software that I use, that gives me 80% of the results, and only purchase those for a lean, cost efficient software stack.
Hopes this helps!
