Editor's Verdict
Editor's VerdictEase of Learning
Ease of LearningClose lets outbound sales teams get started faster since you can make calls and send messages with minimal fuss, especially if you're used to high-volume outreach. Everything's in one place, so you skip the tool juggling. The catch is, if you want a flexible CRM or need to bring in your own tools, the learning curve spikes and some rough edges show up, making setup less smooth for anyone outside their core audience.
HubSpot, on the other hand, throws a lot of complexity at you right away, even for basic stuff. The interface is clunky and packed with more fields and options than most small teams want. Unless you've got someone dedicated to setup and training, you'll run into constant friction, and getting everyone actually using it is a struggle. It's not realistic to get up and running in less than a day, especially for smaller teams.
If your team is outbound sales and needs to get moving fast, Close is the less painful option. HubSpot might be fine for bigger companies with admins to handle the mess, but for quick, easy ramp-up, Close has the edge.
Workflow Presence
Workflow PresenceBoth Close and HubSpot fall short when it comes to showing up where your team already works, but Close makes you live entirely inside its own ecosystem for calls, texts, and email. If your team prefers using external tools like Gmail, Dialpad, or Aircall, Close just doesn't play along, you're stuck switching back and forth, which adds more admin and frustration.
HubSpot isn't seamless either. You have to send emails through their CRM or remember to use their extension and jump through hoops to make sure things log correctly. If you miss a step, you're left cleaning up incomplete data, which is a headache, especially for smaller teams.
If you have to pick, HubSpot is slightly less rigid. At least you have some shot at logging activity from your usual tools, even if it's clunky and unreliable. Close just locks you in and forces constant switching if you want to keep using your team's preferred apps. Neither is great, but HubSpot is the lesser evil here.
Team Adoption
Team AdoptionNeither Close nor HubSpot makes team adoption easy, and both end up creating friction that pushes people to work around the system rather than stick with it.
Close can work for high-volume outbound sales teams who want to live entirely in one platform and are willing to adapt to its workflow, but as soon as your team wants flexibility or relies on outside tools, it feels rigid and clunky. The immature features and weak mobile experience make it even tougher for teams that need to move fast or work on the go. Unless everyone is fully on board with Close's way of selling, you'll run into resistance and workaround habits that kill long-term adoption.
HubSpot doesn't offer a smoother ride. Smaller teams in particular will struggle with the steep price jump after the first year and fiddly email logging that often just breaks, making it hard to trust the system or keep everyone engaged. Even when it's less painful than Salesforce for larger teams, hidden integration headaches and mounting costs mean teams end up frustrated and adoption stalls.
Both are a struggle, but if your team is a high-volume outbound sales group ready to commit fully to a single platform, Close might be slightly easier to keep everyone inside day to day. For most other teams, neither is a clear win, you'll probably run into adoption issues with both.
AI Assistance
AI AssistanceBoth Close and HubSpot offer basic AI features, but neither one will overhaul your workflow or save you from reaching for outside tools. Close gives you call transcription, summaries, and some helpful data enrichment, but it all feels like early-stage tech that's just there for the sake of having it. The time savings are minor, and you'll still want a better note-taking solution.
HubSpot isn't much stronger overall, but its data enrichment is actually useful and does save you time by auto-filling company details. That's the only AI feature that stands out, and it's enough to give HubSpot a slight edge if you care about skipping manual research. Everything else is just as forgettable as Close, so don't expect either one to seriously lighten your workload.
If AI actually saving you time is your main concern, HubSpot is a bit more helpful thanks to its data enrichment, but the gap is small and both are pretty limited.
Integrations
IntegrationsHubSpot gives you a much broader set of integrations than Close, but you have to put in real effort to get them running well. The API isn't as easy as some competitors, so setting up or customizing connections can drag on and need ongoing babysitting. Still, once you get through the initial hassle, HubSpot's integrations are reliable and actually add value, especially for teams willing to put in the work.
Close, on the other hand, pretty much locks you into its own built-in calling and SMS tools. If you want to use your favorite third-party calling platform, you're out of luck. The email sync is fine for the basics, but you miss out on deeper integration features like syncing attachments or calendar events. Basically, if your workflow depends on mixing outside tools, Close is going to let you down and force you into manual work.
So if you care about high-quality integrations and need your CRM to play nicely with the rest of your stack, HubSpot is the clear pick here, even if it's not effortless, at least it's possible and reliable once set up. Close is only workable if you never plan to leave its walled garden.
