Simple CRM

Build an internal tool for my team: "Simple CRM".

The problem: We pay for a giant CRM and use about ten percent of it.
Who uses it: a team of 1–15 people.

What it should do:
- Contacts: People and companies, with owner, stage and the last thing that happened.
- Next follow-up: Every contact has a next-step date. Overdue ones float to the top in red.
- Log activity: One button to record a call, email or meeting, and set the next follow-up.
- Pipeline view: Deals by stage with a total value per column, for the Monday meeting.

Data:
- Contact { name, company, email, owner, stage, next_follow_up_at }
- Deal { contact_id, value, stage, expected_close_at }
- Activity { contact_id, type, note, happened_at, by }

Constraints:
- Built for one team inside one company. Simple sign-in (or none), no billing, no multi-tenant setup.
- Fast, calm and obvious enough that teammates need zero training.
- Data must persist and be shared across the team.
- Ship the simplest version that works, then tell me what you'd add next.
