Capital allocation inside an AI venture studio.
Reinvest, build a new brand, reduce debt, distribute. The four legitimate uses of portfolio cash flow, the default ordering Cobalt Glacier holds to, and the annual written argument that keeps allocation decisions honest over decades.
Tuck-in versus new platform brand: how we decide which a deal is.
A real tuck-in requires customer, workflow, and data model overlap with the parent brand. Anything less is a new brand pretending to be a tuck-in. Cobalt Glacier's default is new platform — we'll protect operator continuity at the cost of headline synergies.
Open source dependency risk in B2B SaaS diligence.
License risk is the smallest of three. License drift, maintainer collapse, and supply-chain compromise are the underwriting questions that matter on a twenty-five-year hold. The Cobalt Glacier dependency workstream and remediation pattern.
The three SaaS quality-of-earnings adjustments standard QoE misses.
Engineering investment, deferred revenue mechanics, and CAC economics are the three QoE adjustments most often missed in lower-middle-market B2B SaaS — and the three that most change the steady-state earnings number a long-hold buyer will own.
Proprietary data is the only real AI moat in vertical B2B SaaS.
Model access is not a moat. Cobalt Glacier builds AI features on the data behind them — workflow-generated, non-obvious schema, closed feedback loop — not the model in front of them.
Gross margin floors in AI-native B2B SaaS: how we underwrite the cost stack.
Cobalt Glacier's 70% steady-state gross margin floor for AI-native brands, the three axes that determine where the floor sits, and the patterns that disqualify a brand idea regardless of topline growth.
Customer concentration is the most underpriced risk in lower-middle-market SaaS.
How Cobalt Glacier underwrites customer concentration on three axes — revenue share, contractual entrenchment, and narrative dependence — and the diligence workstream we actually run.
Why we pass on most venture-backed B2B SaaS operators as co-founders.
We pass on most venture-backed SaaS operators not because they are bad operators, but because a venture capital stack is mismatched with a patient-capital building period. The structural reasons, and the narrow conditions under which we lean in.
Free cash flow conversion is the underwriting bar in B2B SaaS.
Why we underwrite every Cobalt Glacier brand to a steady-state seventy-five percent free cash flow conversion ratio, the four reconciling items we focus on, and what disqualifies a brand idea from our process.
LP-grade reporting for a patient-capital AI venture studio.
What we publish quarterly and annually, the governance stack behind the reporting, and why we hold ourselves to an institutional reporting standard nobody is making us follow.
Concentration is the strategy: why a five-brand portfolio is the right shape.
Why Cobalt Glacier holds five B2B SaaS brands on purpose, what concentration buys us that diversification cannot, and the specific conditions under which we will add another.
How we underwrite a new brand for a 25-year hold.
Three filters every brand idea has to clear before we greenlight it, what changes when the hold period is twenty-five years, and why the discipline is in the ideas we walk away from.
