The team at tectonic is extremely knowledgable, friendly & professional! They are always willing to work with our needs/requirements as they evolve over time - even if those changes require some serious thought or change in approach (which we appreciate!). If you want true experts who can handle your technical implementation challenges from concept development through post-migration support this is THE firm for it!! Highly recommend them. Our organization uses sales force automation tools primarily but also has an extensive suite of custom apps developed by us that integrate into SFDC via connectors. We've been working closely with their teams since day 1 which really sets them apart from others in terms of long term commitment.
