Already Being Migrated to ARGUS Intelligence?

Altus is actively migrating ARGUS Enterprise customers onto ARGUS Intelligence — and the company's CFO disclosed on the Q3 2025 earnings call that those migrations land with a roughly 16% blended price increase, with Altus actively steering customers toward a new asset-based pricing model that scales with the size of the portfolio you run through it. For lean acquisitions teams, syndicators, and growing sponsors, that combination lands harder than the old per-seat structure.

In Altus's Own Words — Q3 2025 Earnings Call

"On a blended basis, we're seeing about a 16% price increase."
"Our net revenue retention... is well north of 100%."

— Altus Group CFO, Q3 2025 earnings call (November 2025).

The translation: customers are absorbing the increase because rebuilding their models elsewhere is painful. That switching cost — not price, not feature parity — is the moat. The migration moment is the one window in your contract cycle where you are already paying it.

Here is the underrated part: re-modeling your portfolio in ARGUS Intelligence is not free either. You are already redoing the work and signing a new contract. That is the one moment where the switching cost of evaluating an alternative is already on the table — and the natural time to put Solsten side-by-side with ARGUS Intelligence on the same deal before you lock in the next contract cycle.

Asset-Based Pricing Math

Your cost grows with portfolio size, not just seats. Solsten pricing stays predictable as you scale.

Re-Modeling Anyway

If you have to rebuild your rent rolls and assumptions in ARGUS Intelligence, you can rebuild them in Solsten in the same import wizard step.

Founder-Level Support

You get the founder on the phone for onboarding. As Altus moves more support offshore, that contrast matters more.

Why Professionals Are Switching from ARGUS

$3K–$10K Per Seat

ARGUS Enterprise pricing shuts out individual investors, small firms, and emerging operators — even those who need institutional-grade analysis.

Desktop-Only

No cloud access. No real-time collaboration. Sharing analysis means exporting files and emailing them back and forth.

Steep Learning Curve

ARGUS requires specialized training. Many firms pay for certification courses on top of software fees.

No AI Assistant Layer

No conversational assistant grounded in your property model. Teams still rely on manual review to explain assumptions, timelines, and output changes to stakeholders.

Where ARGUS Still Wins

We believe in transparency. Here's where ARGUS currently has an edge:

  • IFRS 16 / ASC 842 lease accounting compliance — important for public REITs and institutional mandates.
  • 35+ year industry track record — ARGUS is deeply embedded in institutional workflows and training programs.
  • On-premise deployment — some institutions require local installations for compliance reasons.

For most investors, analysts, and firms — Solsten delivers everything you need at a fraction of the cost. If you require IFRS compliance or institutional mandates, ARGUS may still be the right fit.
