It depends on your size. Vellum is the closest match on what Serial 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.
Serial is no longer listed as active, so anyone still relying on it should plan a migration to one of the alternatives above.
Every company here is Y Combinator-backed and was matched to Serial 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.
