Which plan to pickStart on Free to check the data covers your market. Basic suits one person prospecting; Professional is worth it if you also call prospects or want AI scoring. Monthly billing costs noticeably more than the yearly prices shown.Start the 14-day trial and see how many conversations Fin handles, because that number drives the bill more than seats do. Most teams with more than a couple of agents end up on Advanced for the workflows. If you already run Zendesk or Salesforce and like it, try Fin on its own first.Multichannel is the best value if you use LinkedIn at all, since the add-ons on Email Volume quickly cost more. Only look at Jason AI SDR once your manual sequences are already booking meetings.
