It depends on your size. Vellum is the closest match on what Keep actually does. If you need something more established, sort the table by team size — larger teams generally mean more support and a longer track record. If budget is the constraint, the earlier-batch companies are usually the ones still competing on price.
Keep has been acquired, which often means pricing, roadmap or support changes. That is the usual reason people start looking at this list.
Every company here is Y Combinator-backed and was matched to Keep on what it actually does — its own description of its product — rather than on a broad category label. Batch, team size and operating status come from the YC directory and are shown as-is. We do not rank by payment.
