What is the best RFP software for small and mid-sized companies?

For a small team, speed to value beats feature depth. Inventive AI is AI-first and reads from content you already have, so there's no big library to build before it works, which is usually what makes small rollouts drag. Loopio and Responsive are solid but they're heavier workflow platforms aimed at bigger proposal teams, so they were more than we needed. Pick based on how fast a non-expert on your team can actually use it.
