Haldenmiller: model before diligence

Haldenmiller is a founder-led company preparing a first round. The product had early revenue, but the model was a template with a single blended churn number. Leadership knew investors would ask for numbers they could take apart.

As Haldenmiller prepared to raise, several gaps showed up at once:

• The spreadsheet broke when assumptions changed
• Unit economics lived in a slide, not a working workbook
• Blended churn hid what cohorts were actually doing
• Diligence asked for scenarios the model could not stress
  ‍

Although the team had slides and a spreadsheet, those materials did not answer diligence. The founder did not need another pitch rewrite. They needed a linked model that could survive a partner opening the tabs.

Logifx began with a brief focused on what Haldenmiller sells and to whom. This included:

• Rebuilding drivers as a linked five-year model
• Separating cohort retention from blended churn
• Stress-testing base, upside, and downside cases
• Documenting assumptions investors can edit
  ‍

Rather than filling a template, the approach centered on numbers an investor can challenge. The goal was deliverables the founder owns, not a deck for the shelf.

After delivery, Haldenmiller had a workbook diligence could open:

• Five-year linked statements that update together
• Cohort retention instead of a single churn number
• Base, upside, and downside scenarios stressed
• A clear burn path past month twelve
  ‍

The founder reported clearer answers in diligence, fewer stalled investor threads, and a workbook they could edit. Importantly, this arrived as a flat fee paid on delivery, without a retainer.

Following delivery, Haldenmiller uses the memo and model through diligence. Logifx does not introduce investors or take a share of the raise. The documents stay with the founder.
