Software application adoption is very different for early-stage startups compared to established businesses. Very different growth-stage problems. For me personally, these platforms I find to be consistent across, regardless of the growth stage of the company, with a lot of the clients I work with or have worked for. Asana or Clickup for project management, Slack for communications, 1Password for login credentials management, Notion and Google Drive for document management, Figma for wire framing and designs, Zoom for video comms, Zapier for integrations/workflows, and Loom for quick video instructions. Aside from that, other platforms choices across email marketing, CRM, development, (etc) is normally bespoke and comes down to the individual companies themselves.
