Gitlab is a good example, we had to leave the free tier in order to get features that Gitlab specifically chose to be in the paid tier because their absence is a big blocker when you grow... So we pay $100/mo/seat on Gitlab.
We also use at least 10 paid general-purpose tools that each fill a real need (we don't keep tools we don't use):
- Notion for knowledge management
- Airtable to manage operations data (not customer data)
- Hubspot for Sales and Marketing
- Lattice for HR
- Spendesk for expenses management
- Quickbooks for accounting
- Typeform for various customer feedback
- Zoom for remote work and link between our offices
- GSuite for everything in it
- Figma for UI design
- Recruitee for recruitment management
And finally, add also at least 10 paid Engineering-specific tools:
- Gitlab of course
- AWS for hosting of course
- Cloudflare for DNS stuff
- Sentry for error reporting
- Crowdin for internationalization
- FullStory for UX studies
- Apollo engine to get decent analytics about our backend
- Webflow for our Website (Not for the webapp of course)
- Pagerduty for operations
- We used Cloudcraft at some point to have an idea how our AWS stack look like
I could go on... But in the end, you end up with ~10 Saas tools peer seat, with costs from $2 to $100 per tool. And it is valuable, we pay them because they are worth it. But yes this is an interesting trend...
