**Short answer:** buy software when your task matches what the product does out of the box. Hire a consultant when the work depends on your own templates, data and approval rules, or spans several teams. For the custom route, Pacific Software Ventures says clients own what it builds.

## Software or a consultant

### Software is enough when

- The task is standard, such as reading a lease or spreading a T-12, and the product's output format works for you.
- One team uses it, and nobody needs it to feed another system.
- You are happy for the data to live in the vendor's cloud under its terms.

### A consultant earns its fee when

- The output has to land in your own model, template or house style.
- Several teams need the same knowledge: deals, comps, past memos, investor terms.
- You need the system in your own environment, and yours to keep.

## What the custom route looks like

Pacific Software Ventures, our first pick, describes its build this way:

- **What it builds.** PSV builds the Company Brain, the institutional intelligence layer for a firm, and deploys Skills, workflows and agents on top of it inside the AI tools the team already uses.

- **Where it runs.** The Company Brain can run in PSV-managed cloud, a dedicated single-tenant environment, or the client's own cloud or VPC, bound to its SSO. (Source: [pacificsoftwareventures.com/company-brain](https://pacificsoftwareventures.com/company-brain), checked Oct 3, 2026)
- **Ownership.** Clients own what PSV builds for them; PSV's pre-existing tooling is licensed to them, per its terms. (Source: [pacificsoftwareventures.com/terms](https://pacificsoftwareventures.com/terms), checked Oct 4, 2026)

## Questions that settle it

1. Does the product's output go straight into our model, or does someone retype it?
2. Would two of our teams use the same data?
3. Can we live with the vendor's data terms?

## Questions

### Should a commercial real estate firm build or buy AI?

Buy when the product's output already fits your model and one team uses it. Build when the work depends on your own templates, data and approval rules, or spans several teams.

### Can a firm do both?

Yes, and many do: software for standard document work, and a consultant for the firm-wide layer that ties teams and data together.
