For Startups
Playbooks, decision frameworks, and case studies written for startups.
Your AI Feature Doesn't Need More Data. It Needs a Harder Objective.
Most AI feature stagnation is not a data quantity problem. It's an objective mismatch — your model is perfectly optimizing a proxy metric that quietly diverged from the outcome users actually care about.
AI Prompt Versioning Cheatsheet: Track, Rollback, Deploy
A scannable reference for shipping prompts to production without breaking output quality. Covers versioning schemes, rollback patterns, regression testing, and the dev-staging-prod promotion pipeline most teams skip.
Questions to Ask Before Hiring an AI Fintech Dev Partner
Most AI fintech vendors demo well and use the right words. These 15 questions separate the ones who have actually shipped under regulatory and credit-risk constraints from the ones who haven't.
How GimBooks Served 3M Users Without a Broken Ledger
A teardown of the inflection point most accounting SaaS hit between 50K and 500K users — where ledger drift, reconciliation failures, and AI categorization errors look like three problems but are actually one. Here is what we learned shipping through it with GimBooks.
Batch vs. Real-Time AI Inference: A Decision Framework
Most teams default every AI feature to real-time inference and overpay for latency they don't need. The right question isn't how fast your model runs — it's whether a stale answer causes a worse user decision.
Stream LLM Tokens to a React UI Without Melting Your Server
Most LLM streaming tutorials skip the part that actually breaks under load: backpressure between OpenAI's ReadableStream, your Node response, and the browser. Here's the three-line fix and a working tutorial that survives concurrency.
How to Run a Shadow Deployment Before Your AI Feature Goes Live
Staging tests passed, but staging traffic looks nothing like production. Here's the shadow deployment playbook senior engineers use to validate an AI feature against real inputs before a single user sees an output.
Your AI Model Isn't the Product. Your Retraining Loop Is.
Most teams confuse deploying a model with building an AI product. The model you shipped is a depreciating asset — the retraining pipeline behind it is the only thing that compounds.
Event Sourcing for AI Products: Why Your Model Needs a Time Machine
Your CRUD database can tell you what your AI decided, but not why — because the world it saw at decision time is already gone. Event sourcing is the architecture that gives your model a time machine, and it's the prerequisite for any serious AI audit trail.
5 Mistakes We Made Shipping AI to a Live Pharmacy Marketplace
A field-level post-mortem on what breaks when AI substitution, routing, and recommendation features hit a real e-pharmacy catalog. Five specific mistakes, the symptoms you'll see in production, and how to recover without rolling everything back.
Ship a Drug Interaction Alert With a Local LLM in 7 Steps
A runnable tutorial for CTOs at e-pharmacy startups who need drug interaction alerts without sending patient data to OpenAI. Uses Mistral 7B locally, a versioned interaction dataset, and citation-grounded extraction.
How KarroFin Scaled AI Credit Scoring Without Killing Approval Rates
KarroFin's credit model wasn't broken. No alerts, no errors, no engineering fires. But approval rates were quietly compressing at scale — and the fix wasn't where the data science team was looking.
