Sparse helps solo freelancers and tiny agencies send tracked, signable proposals a few times a month without paying a full proposal-suite seat tax. Credits you can pause when the pipeline is quiet.
Public reviews of tools like PandaDoc and Proposify keep repeating the same pattern: monthly price for intermittent use, free-credit cliffs, and paying suite prices just for e-sign + open tracking. Sparse is validating a thinner product: template → send → track → sign, with pause/credits billing, before we build the full editor.
