What 303 Software does

303 Software is a privately held, founder-owned custom software development firm headquartered in Denver, Colorado, operating since 2006 across the U.S. domestic market with a primary emphasis on regulated verticals. The company delivers end-to-end web, mobile (native iOS via Swift/SwiftUI and cross-platform via Kotlin Multiplatform), and AI-integrated applications for SMBs, startups, and mid-market enterprises, with particular depth in healthcare (HIPAA-compliant portals, telehealth, EMR integration), fintech (PCI-compliant builds), and mining safety (MSHA compliance tooling). Its core technology stack emphasizes senior-led Agile teams, peer code review, static security scanning, and a proprietary System Design & Planning (SD&P) framework that gates large builds behind fixed-price planning engagements; AI capabilities include custom RAG-based copilots (e.g., MSHAWise), twelve named workflow agent patterns (ERP Bot, Forecast Copilot, Voice-to-Field Log, Compliance Monitoring), and a Vibe Check code-review service for AI-generated code.

The business model is a hybrid of professional services and recurring revenue. One-time planning engagements start at $997 for Needs Analysis and $12,000 for an SD&P Roadmap; full App Development engagements run at $20,000/month minimum on a 6-month commitment; ongoing maintenance plans are priced monthly from $179 (Essentials) to $499 (Premier) with combined Web & Mobile coverage at $469/month; and emerging Vibe Check / Vibe Build / Vibe Live subscriptions range from a $997 review up to $2,997/month retainers. Fractional CTO and consulting work provide further subscription-like recurring revenue. Go-to-market is sales-led and direct, with senior leadership involved in discovery, supported by content marketing, SEO, referrals, and event presence (CES, Western MSHA Conference). Customer mix spans enterprise (Johns Manville, Genesis Inc.), mid-market (Zing Credit Union, Comfort Dental), and startups (Simple Farms, Acensa Health, MSHAWise), and the company reports a 95% client retention rate and 97% on-time delivery across 200+ projects.

303 Software remains unfunded and is independent of external capital, with no disclosed parent company, M&A activity, or institutional investors; ownership and operating control have stayed with co-founders Matt Jaffe and Stefan Ramsbott since inception. The trajectory since 2023 has shifted from pure custom development toward productized AI services and vertical compliance tooling, while maintaining the founder-led, senior-engineer delivery model that anchors its brand and pricing.
