Dear other entrepreneurs, what online tools have you purchased during your founding journey?

I'll be honest, I'm just looking for what other founders have spend money on for research purposes. I know founders make radical spending just to save time or whatnot to progress their startup or business – I have done so myself. I have been a founder myself for multiple startups so I will go ahead and start and listing the things I bought. You guys can tell me if certain spending decisions are bad, and we can do it for each other as well to save money for all founders. Maybe this thread can be a help for everyone involved who are like me in wanting to know more information regarding spending on softwares used for business growth.

I know your guys' information is valuable, so I'll offer mine upfront. I hope we can collectively build value – whether that be advising on each others' spending decisions, and also to gain collective knowledge on what founders spend money on for a win-win.

For me, I used to do a marketplace business that connects advertisers and businesses (now closed), but here are the services I paid for back during the 6 month process:
– supabase ($30ish/month) – for 2way database that firebase doesnt offer
– bubble ($43ish/month w/plugins) – for easy web app building and backend support
– framer ($100ish/month) – for beautiful animated front end for homepage
– zuplo ($25/month) – for api endpoint building though i just used the typescript functionality the most
– ahrefs ($129/month) – for getting started in backlink building and seo and competitor analysis and stuff like that
– fiverr homepage figma design ($138)
– fiverr seo 200 backlinks ($58)
– fiverr email scraping outsourcing ($100)
– hubspot (20$ish)
