Everything You Need to Know
Clear answers regarding UK deployment timelines, security standards, and customization capabilities.
What is the difference between a HubSpot Custom App and an integration?
A custom app runs natively within your HubSpot portal via UI extensions and custom CRM cards, giving your team bespoke tools directly on contact and deal records without leaving HubSpot. Integrations typically connect external tools in the background via APIs.
How does AI data cleanup protect our existing HubSpot data?
We never delete records destructively. Our algorithm uses fuzzy matching with confidence thresholds, merging contact histories, notes, and activity timelines into the master record while preserving full audit trails.
Can you build AI workflows that trigger WhatsApp or Telegram messages?
Yes! Powered by AtNimo, your HubSpot workflows can automatically trigger personalized WhatsApp or Telegram messages when deals move stages, tickets are resolved, or leads meet qualifying scores.
How long does a custom HubSpot app or AI workflow build take?
Custom app and AI workflow builds are delivered in focused, agile milestone sprints, including architecture design, sandbox testing, team training, and production deployment.
