This is possibly misleading as this 20-Person company is obviously not yet at a phase where they have a mature customer acquisition pipeline. It's obvious because they're on basic or free tiers for all these services.
As soon as they try to land a customer with any sort of compliance requirements, the pricing tiers on nearly all these SaaS plans will jump significantly. It's unrealistic to expect to pay less than one full time employee for basically all your supporting infrastructure.
SaaS is definitely great to start out, as demonstrated here, but the danger is lock-in and expense creep, which can kill otherwise strong companies. Burn cash to accelerate but always have an escape hatch ready for when you need to tighten the purse strings.
Intercom alone will cost more than $1,183 once they roll off the 12 month startup plan.
We migrated to Crisp and are much happier @ $99/month.
