Why real estate teams build with Greta instead of agencies or freelancers
Secure file storage with proper access controls is part of our standard build — not an afterthought
We build portals that clients actually use — clean UX reduces the 'I'll just email you' fallback
AI-assisted development cuts the portal build from a 10-week agency engagement to 1–3 weeks
Role permission models are architected correctly the first time — no half-built access control that breaks at scale
Greta vs Freelancers vs Traditional Agencies
Freelancer
Cost
Similar budget range, but file security and permissions are frequently underscoped
Speed
3–10 weeks — complexity spikes around file handling and role permissions
Reliability
Variable — security considerations in portals require discipline the best freelancers provide, the average don't
Quality
Often produces a basic file-sharing tool without the UX that replaces email workflows
Traditional Agency
Cost
2–4× more, with significant discovery around compliance and security requirements
Speed
12–20 weeks with stakeholder reviews and security audits
Reliability
High, but enterprise-focused processes slow delivery significantly
Quality
Highly polished and secure, but often over-featured for service businesses that just need a clean client interface
