Best CRM for an app based company?

We’re a B2B startup that’s primary an app (website is secondary) and looking for a CRM that integrates well. Ideally we’d get an all-in-one solution for marketing, sales, and customer support.

We met with EngageBay, ActiveCampaign, Hubspot, Insightly, zoho, and a few others. Hubspot is great but very expensive.

Any suggestions?
