Honestly, if you're super small and a one person sales team — just sequence through Apollo directly.
Hubspot will simply house your contacts, companies and deals that you've sequenced through Apollo (as long as it's integrated properly)
Another option (if you have the correct level of Hubspot support) would be to push data from Apollo to Hubspot and sequence from within Hubspot.
If you just want an easy plug and play. Go with the first recommendation.
