AI product engineering, by people who ship their own

We build AI-native products for ourselves and for clients, so we know the difference between a demo and a feature your customers can depend on. Cost, latency, abuse, fallbacks: handled.

Engagements

Four ways to work with us

AI Integration

from $750

Claude and OpenAI wired into your product the production way: vision pipelines, structured extraction, RAG over your data, and agent workflows, engineered for cost ceilings, rate limits, abuse prevention, and graceful fallbacks.

Claude & OpenAI APIs, agents, RAG, MCP
Prompt design with measurable evaluation
Usage metering, quotas, and cost control

AI Document & Workflow Automation

from $1,500

PDFs, scans, and images turned into structured data that flows into your systems. Human-review queues where accuracy matters, monitoring where volume matters.

PDF / image → structured data pipelines
CRM, ERP, and back-office integrations
Deployed endpoints with monitoring

Mobile Apps & App Store Rescues

from $500

Native iOS and Android apps end to end, plus fast fixes for apps that are stuck. StoreKit 2 subscriptions, entitlement verification, App Store rejections, TestFlight and App Store Connect problems.

SwiftUI and Kotlin, subscriptions & IAP
Server-side receipt (JWS) verification
App Store submission, done right the first time

Why Gold Bits

We eat our own cooking

Empty repo → App Store

in under a month

Unscribble: on-device OCR, Claude/GPT vision pipeline, StoreKit 2 subscriptions, anti-abuse backend, A/B-tested paywalls. Built and submitted solo.

3 products

live and operating

Unscribble, OneFit AI, and MyMembrs. We run our own AI products, so we build client work the way owners build: for cost, retention, and reliability.

Full stack, one team

no handoffs

iOS, Android, web, backend, AI pipeline, payments, analytics, and app store operations handled by the same engineers who architected the system.
