Ideas for real problems, built on apps that already exist
Businesses in every industry lose time and money to the same few problems. Most can be solved by joining services that already exist: payments, WhatsApp, calendars, maps and AI. Pick an industry, open an idea, and see exactly what would be built and how it works.
What is an MCP server?
MCP (Model Context Protocol) is an open standard that lets an AI assistant use other apps as tools: read a calendar, search files, update a CRM. If an app has an MCP server, an AI agent can use it without anyone writing a custom integration.
Where the margin comes from
- Usage costs rise with customers, so a small base is never a big bill.
- You skip months of building payments, messaging and maps, so the app launches sooner and cheaper.
- The value is the workflow you add. Customers pay for the outcome, not for the API calls.
Problems businesses face, by industry
Clinics and healthcare
- Patients miss appointments and the slot is wasted
- The front desk answers the same questions all day
- Consultation fees are collected by hand
- Patient details are scattered across paper and chats
Real estate
- Leads from ads go cold before anyone calls
- Agents forget to follow up
- Site visits get double-booked
- Buyers cannot quickly find what suits them
Online stores and D2C
- "Where is my order?" fills the inbox
- Returns and refunds are handled over chat by hand
- Carts are abandoned with no follow-up
- Cash-on-delivery orders are not confirmed
Schools and coaching
- Fee reminders are chased by hand
- Parents ask the same questions again and again
- Batch timings and changes are hard to communicate
- Results and attendance reach parents late
Gyms and wellness
- Memberships lapse quietly
- Trial leads are never followed up
- Renewals are forgotten
- Class booking over WhatsApp turns into a mess
Restaurants and cloud kitchens
- Table booking happens on the phone
- Orders from WhatsApp mix with everything else
- Repeat customers are never nudged
- Feedback is ignored
Field services and logistics
- Jobs are assigned by phone calls
- Customers keep asking for an arrival time
- There is no proof the work was done
- Invoices go out late
Wholesale and manufacturing
- Distributors reorder by calling
- Order errors and rework
- Credit limits are tracked in a spreadsheet
- Payments are chased by phone
Agencies and professional services
- Invoices are chased by hand
- Client reports take days to put together
- Meeting notes and actions are lost
- Founders drown in email and scheduling
Creators and media
- Turning one video into many posts takes forever
- Sponsor deals and deadlines are tracked in notes
- Memberships are managed manually
- Posting consistently is hard
Ideas
- Clinic front-desk assistant: Answers patients on WhatsApp, books the slot, takes the fee and sends the reminder.
- Invoice-to-cash assistant: Reads invoices from email, tracks who owes what, and chases politely until it is paid.
- Property lead-to-visit app: Takes every ad lead, replies in seconds, and books a site visit with directions.
- Online store order assistant: Tracks orders, handles returns and answers "where is my order?" on WhatsApp.
- School fee and parent assistant: Collects fees on time and answers parents' questions without a phone call.
- Gym renewals and trial follow-up: Follows up every trial, renews members before they lapse and wins back the quiet ones.
- Restaurant table and order assistant: Takes bookings and orders on WhatsApp and brings regulars back.
- Field service dispatch app: Assigns jobs to technicians, shows the route and keeps the customer informed.
- B2B reorder app: Distributors reorder in a chat, and you get a clean order sheet and payment link.
- Client reporting assistant: Pulls the numbers together and writes the client report in plain words.
- Creator content studio: Turns one long video into posts, shorts ideas and a week of captions.
- AI chief of staff, built on MCP: One assistant that reads your mail, calendar and notes and does the routine work.
Things to watch
- Provider prices and terms can change, so build with the option to swap a provider.
- You depend on other companies' uptime and rate limits.
- Customer data passes through several services. Privacy and consent need care.
- Some APIs have approval steps before real customers can use them (for example WhatsApp and Google).
