Grindstoneby REFM

For real estate programs

Prove every class graduates with sharper deal judgment than the last.

Grindstone gives your students reps on real deal decisions with a Socratic coach, and gives your department a measure of judgment across four rings, class after class.

The problem

Employers wish judgment was more developed in new graduates

01

Coursework grades the model

Placement depends on judgment, but most assignments reward a correct spreadsheet, not a sound call.

02

Faculty time doesn't scale

No professor can walk every student through every deal. The students who need it most get the least.

03

Employers end up teaching it

New hires arrive able to build the model but not to question it, so firms spend the first year teaching the judgment they hoped to hire.

Inside a session: no math, no modeling. All judgment.

Brentwood Medical II · Ring III prompt

Measured year over year

See whether each class is getting better, and where

Every case scores reasoning on four rings: the asset, the capital, the people and the cycle. Compare this year's class with last year's, ring by ring, and see where your curriculum is working and where it needs attention.

Average judgment score by ring

Each bar is one graduating class. Scores run 0 to 100.

How it runs in a course

Fits the syllabus you already teach

01

Faculty assign

Pick cases from the landmark library and assign them to a cohort, in the order your syllabus needs.

02

Students work the deal

The coach probes their reasoning until they commit to a call. It never gives answers or does the assignment.

03

You see the results

Completion and ring-level results roll up by student and by cohort.

Ask the Coach

Practice defending the call out loud

For all cases, students can record themselves arguing their position, the way they would to an investment committee or in an interview. The coach listens and critiques the reasoning: what held up, what they skipped, and where a skeptical partner would push. It is ungraded and each attempt is saved as text with its critique, so students can go back and study how their argument improved.

  1. 01

    Record. Students talk through their call for 30 to 90 seconds, right inside the case.

  2. 02

    Get the critique. Their words are transcribed and the coach responds to the reasoning. Nothing is scored.

  3. 03

    Come back and study. Each attempt is saved as text with its critique, private to the student, so they can review how their argument improved. The audio itself is never kept.

Coach critique

You made a clear case on rent growth, but you never said what happens if the loan can't refinance in year three. A committee would ask that first. What would have to be true for you to walk away?

Saved attempts3 on this case

  • Attempt 3, todayTranscript + critique

    “I'd only proceed with a rate cap and a lower loan amount...”

    Coach: Good. Name your walk-away point.

  • Attempt 2, TueTranscript + critique

    “Rent growth covers the refinance risk because...”

    Coach: Refinance still unaddressed.

  • Attempt 1, MonTranscript + critique

    “The deal works on rent growth alone...”

    Coach: What if it can't refinance?

Interview Prep

Interview practice built into the coach

Student accounts get Interview Prep inside Ask the Coach: stock interview scenarios across the risk spectrum, from core to distressed, plus any question a student expects. Answers are spoken and critiqued, and the coach stays Socratic; it never supplies the answer.

Market deals gives students a daily feed of real transactions from the CRE trade press, searchable by metro, property type and financing. One click turns any deal into an interview question, so market fluency becomes a habit.

  • Stock scenarios from core to distressed, or your own question
  • Market deals: fresh transactions daily, filterable on a US map
  • Every spoken answer saved with its critique

What faculty see

Results, not transcripts

The cohort view shows completion, ring coverage and the students who need attention. Each student's detailed feedback stays private to them, so they can reason out loud without performing for a grade.

Landmark Cases

The deals that made the industry, produced as cases for your students.

Our Landmark cases put students in the chair at a real deal's hardest decision point. Every Landmark case is drawn from a documented North American CRE transaction between 2005 and 2025: Stuy Town, Equity Office, the Hilton LBO, Hudson Yards, the Brookfield DTLA defaults, the office reckoning. Reconstructed from primary sources, stripped of spoilers, and rebuilt as Socratic judgment cases across four rings.

Privacy and consent

Students choose to share

Students join a cohort and agree before any results are shared with faculty. Enrollment is confirmed against registrar records, so only your students are counted in your numbers.

For the department

What your program gets

Evidence for accreditation

Year-over-year judgment results you can put in front of accreditors and your advisory board.

A stronger placement story

Tell employers what your graduates can do, with numbers behind it.

Records students can show

Each student earns a completion record to link from a resume, showing the work, never the scores.

Questions

Does it fit an existing syllabus?

Yes. You choose which cases to assign and when, so it slots into the course you already teach.

How big can a cohort be?

Cohort plans cover whole classes, with up to 200 case assignments per cohort.

What can faculty see?

Completion, ring-level results and who needs attention, for students who agree to share. Not their conversations with the coach.

Who pays, the department or the students?

Either. Departments can fund a cohort, or students can join on the student plan and link to your cohort.

What about academic integrity?

The coach never writes, rewrites or answers assignments. It only asks questions that push the student to reason it out.
