Sport Auto Plus: Website, App & Platform Development and Automation & AI Integration.

Starting point

Sport Auto Plus launched in Bochum in 2024 with car subscriptions for people with a connection to sport — from competitive athletes to gym members. Circle was involved from day one: the first website went live on 1 July 2024. According to a published case study, Sport Auto Plus had already recorded more than 3,000 orders after six months.

Platform

• Three website generations that grew with the company (v1, v2, v3).
• A dealer app built on the trafe stack and a customer app.
• UI/UX design of all web presences and apps from a single source.

The “Normalizer” data hub

At the core was a custom MongoDB-based tool for central data management. The “Normalizer” connected the website, HubSpot, the customer app and the dealer app and kept their data in sync — necessary not least because HubSpot’s APIs only allow a limited number of requests.

Tools and automation

• Introduced Jira and Confluence, set up HubSpot and supported automations with Make.
• Invoicing with easybill through to automatic direct debits with DATEV integration.
• Emails, newsletters and automations with Brevo.

Operations and IT

• Hosting, maintenance and patching (DevOps) and setting up Cloudflare.
• Supported the rollout of Microsoft 365 (E3 with Teams and telephony licences) and email protection with Hornetsecurity.

Handover

In July 2025 we handed the systems over to Sport Auto Plus’s own team, built up in the meantime, which has run operations itself ever since.
