Finance Architect
Digital Asset Infrastructure

Hi, I'm Grant. I design financial systems for institutional operators.

I work with digital asset businesses that have complex products, institutional clients, and regulators who demand rigor. The gap between what the accounting standards say and what blockchain products actually do — that's usually where I feel at home.

I like systems. I like precision. I like when accounting and code actually work together.

Here'swhatIactuallydo.

Financial Architecture

Designing GAAP frameworks for products that didn’t exist when the standards were written. Revenue recognition, policy infrastructure, control environments built to survive audit scrutiny at institutional scale.

ASC 606Revenue PolicyControl EnvironmentsGAAP DesignPolicy Infrastructure

Automation & Systems

Built systems that eliminated $1M+ in audit labor. Automated reconciliation pipelines, audit prep workflows, and financial reporting infrastructure — production code that runs while the audit proceeds cleanly.

IPO & Institutional Readiness

SOX-ready control environments, audit committee governance, S-1 financial infrastructure. The systems that let digital asset businesses survive public market scrutiny — built before the banker calls, not after.

Production Software

Full-stack systems built in TypeScript, Python, and SQL. Onchain data pipelines, FastAPI backends, Next.js frontends, Supabase databases. I don’t advise on software. I build it.

Vibe Coding Is Creating a Security Debt Crisis

AI & Security · 2026-04-17

Andrej Karpathy coined 'vibe coding' — shipping production software by feeling through AI prompts rather than engineering it. The litellm supply chain attack in March demonstrated exactly what happens when AI-generated code reaches production without security review. We are accumulating a security debt that insurance actuaries, compliance frameworks, and liability law are not remotely prepared to handle.

Solo Founders Hitting $1M ARR With Zero Employees: The Tax and Legal Nightmare Nobody Warns You About

Tax & Business Structure · 2026-04-14

IndieHackers is full of solo founders celebrating $1M ARR with zero employees. What's missing from those celebration posts: the self-employment tax on $1M, the S-corp election timing you probably missed, the QBI deduction phase-outs you didn't budget for, and the multi-state nexus exposure that's accumulating with every remote customer.

The SaaS Extinction Event: When AI Agents Replace Your $7,500/Year Software Stack

AI & Business Models · 2026-04-10

McKay Wrigley cancelled 7 B2B SaaS subscriptions in a single weekend after building replacements with Claude. He's not alone — and the compounding effect of AI-native replacements on SaaS revenue recognition, valuation multiples, and the $700 billion SaaS industry is being dramatically underestimated.

Grant Stellmacher

I'm curious about how things work — accounting systems, protocol mechanics, software. That curiosity is probably why I ended up at the intersection of institutional finance and crypto infrastructure.

Outside of work I stay sharp with CrossFit (Level 1 Trainer), build production software, and generally prefer systems that can be tested.

What I stand for.

01
01
Precision over speed
Do it right the first time. Audit-ready from day one, not after the regulator asks.
02
02
Systems thinking
Every policy, workflow, and control exists within a larger system. Design for the whole, not the symptom.
03
03
Rigor without rigidity
Standards exist for reasons. Applying them to new technology requires judgment, not just pattern-matching.
04
04
Build before you advise
I write the code. I’ve built the product. That changes how I see accounting for it.
