Primer, configured on your model.
Live in 48 hours.

We onboard five acquisition teams a month and we'd love to work with you. Send us your Excel underwriting model. We teach Primer your logic so it does your underwriting first pass in minutes. Cohorts get two weeks free.

  • Configured on your template. Not a generic form. Your actual XLSX, your chart of accounts, your tabs.
  • Live within 48 hours. Onboarded by the team that built Primer. Direct Slack line, no ticket queue.
  • Every cell cited to source. Run it on two weeks of real deal flow before you decide anything.

Who we're onboarding

Built for active acquirers.

Primer earns its keep on real deal flow. If these sound like your team, request a slot.

01

You model in Excel

Not Argus. Not a black-box BI tool. An actual XLSX your analysts open every morning.

02

5+ deals a month

Enough volume that manual data entry is the bottleneck. Under five and you don't need us yet.

03

U.S.-based active acquirer

You're submitting LOIs this quarter, not just evaluating tools. Acquisitions analysts welcome at any title.

All three fit your team?

How onboarding runs

Two weeks on your real deals.

No demo data, no sandbox. You upload live OMs, rent rolls, and T-12s. Primer populates your model. That's the entire test.

Day 0 1

Send us your model.

We map every named range, every formula, every tab. You get your exact template back — ready to populate.

Day 2 2

You're live in Primer.

Upload a live deal OM. Primer returns your populated XLSX with every cell cited to source and conflicts flagged.

Day 14 3

Decide if Primer stays.

Two weeks on real deals is enough to know. If you want to keep going, we talk pricing. If not, no hard feelings.
