Case study: Custom software
Sales outreach CRM with AI replies over iMessage
A subscription CRM that runs personalised iMessage campaigns, with AI drafting replies for the sales team.
Overview
A sales software company needed help with this: a subscription CRM that runs personalised iMessage campaigns, with AI drafting replies for the sales team.
The problem
A sales software company came to us with these problems:
- Traditional SMS outreach tools had low engagement and trust from recipients
- Need for human-like, conversational messaging using iMessage with real US phone numbers
- Supporting a subscription-based model with secure access control
- Separating internal administration from customer-facing functionality
- Ensuring scalability for multiple users and outreach campaigns
What we built
We built a subscription-based CRM platform that enables sales and marketing teams to run intelligent outreach campaigns through iMessage. The system was architected as two connected applications, an internal admin board and a public-facing user dashboard, ensuring secure management, scalability, and a smooth experience for subscribed users.
- IMessage-based outreach using real US phone numbers
- Subscription-enabled CRM for sales and marketing teams
- Separate internal admin panel and customer-facing dashboard
- Scalable architecture to support multi-user campaigns
- Improved engagement through human-like conversations
How it works
The system runs on the tools listed below. Platform names appear here and in the stack, so you can see exactly what was used.
- Frontend: Retool (Admin and External Apps)
- Backend: Custom API server for iMessage communication
- Payments: Stripe & PayPal integrations
- Automation: Retool Workflow Automation
- Hosting: Deployed scalable backend server for real-time message delivery
Result
- The CRM enabled users to run authentic outreach campaigns that felt personal and timely.
- With iMessage integration, users saw an increase in open rates compared to Twilio-based tools.
- AI auto-responses reduced manual workload, and plan-based throttling ensured system stability and compliance.
- The platform now supports dozens of recurring subscribers with consistent performance and measurable sales outcomes.
"Working with MaqMinds was a fantastic experience! Their deep expertise in custom software development really stood out. What impressed me most was how quickly they understood our app’s structure and needs with very little direction from me. They were easy to work with, super professional, and I’ll definitely be hiring them again for future projects. I highly recommend it."
