Well, the strategies and tactics differ depending on a lot of factors. Having been responsible for sales and marketing for small, medium and large SaaS companies, I can tell you that the go to market approach is different as you target small, midsize and enterprise customers.
Without asking a ton of questions, I'll offer a few thoughts. Continually building out your company's knowledge of the specific needs and use cases for your SaaS solution categories at the customer segment and persona levels can be a key growth driver for your business. By doing this, your sales, product and marketing teams add value, deliver better messaging, improve products for your customers and of course this grows your sales. So ask yourself if your company has a process and commitment around capturing and taking action from this kind of information.
Another approach for growing revenue quickly for SaaS businesses is to monitor renewal and CAGR rates at the product and customer segment levels. Understanding price elasticity at the product and customer segment levels can dictate future price increase levels, prioritize investments and more.. Of course you need at least 3+ years of sales to do this effectively. Without knowing the details of your business, I can't get much more specific than this. Hope it helps.
