Independent investment case study

Sardine

I approached Sardine from a bank investor’s perspective. I wanted to understand whether its fraud and risk platform could add something useful to a bank’s existing tools—and whether that would justify the investment price.

The investment question

Could a unified fraud, identity, compliance, and risk platform create enough strategic and financial value to justify a new investment—when the prospective investor already has exposure to the category?

The analysis connects the product thesis to bank use cases, tests the cost of entry against exit outcomes, and identifies the evidence required before an investment decision.

How I approached it

  • Investment thesis: assess the potential for behavioral intelligence, network data, and embedded workflows to create a durable advantage.
  • Strategic fit: map possible bank applications and examine overlap with existing fraud and identity investments.
  • Financial analysis: construct an illustrative cap table, ownership bridge, dilution scenarios, gross returns, and sensitivity analysis.
  • Decision materials: bring the thesis, model, and open questions together in a memo and presentation, with the sources and assumptions recorded.

Investment judgment

Proceed to confirmatory diligence.

Strategic relevance supports further evaluation. Investment approval depends on measurable differentiation, durable bank customer economics, and a price that supports attractive returns.

The central tension is portfolio overlap. A broader platform is valuable only if its signals and workflows improve outcomes beyond the investor’s existing technology exposure.

Commercial value and financial returns should be evaluated separately. A useful bank partnership does not, by itself, justify an investment at any price.

Illustrative economics

The memo and workbook assume a $15 million investment at a $900 million post-money valuation, implying 1.67% initial ownership. All scenarios use a five-year hold.

Memo and workbook scenario set

Downside$1.5B40%1.00×0.0%
Base$4.0B35%2.89×23.6%
Upside$8.0B30%6.22×44.1%

Analytical assumptions, not disclosed financing terms or forecasts. Gross returns exclude fees, taxes, preferences, and follow-on capital. The IC preview uses a separate scenario set: $0.6B, $2B, $5B, and $10B exits with 35% dilution.

The operating model tests the exit assumption.

The workbook’s illustrative ARR build reaches approximately $273 million in year five. At an assumed 8× ARR multiple, that implies approximately $2.18 billion of equity value—below the $4 billion base exit. Supporting that base case requires stronger growth, a higher exit multiple, or another substantiated source of value.

What would change
the decision

  • Product advantage: evidence of better fraud detection, fewer false positives, and incremental value from network intelligence.
  • Revenue quality: verified ARR, retention, expansion, customer concentration, and gross margins.
  • Bank readiness: customer references, implementation timelines, model governance, and data-sharing controls.
  • Entry discipline: actual financing valuation, security terms, preference stack, and a credible ownership path.
  • Strategic fit: a defined commercial pilot that demonstrates value beyond existing vendors.
