What OpenSource Technologies (OST) does

OpenSource Technologies, Inc. (OST) is a privately held, woman-led custom software development agency headquartered in Lansdale, Pennsylvania, founded in 2012 by CEO Manish Mittal and led alongside President Shaili Gupta. Incorporated as a Pennsylvania corporation with 51–100 employees, the firm builds, modernizes, and operates custom software for mid-market US businesses, K-12 districts, higher education, government/SLED buyers, nonprofits, and growing commercial brands. Its stated specialties are legacy system modernization, custom web and cross-platform mobile application development, API and systems integration, cloud-native/DevOps work, and AI/LLM integration. The company reports 150+ to 500+ completed projects across 35+ countries and maintains a 4.8/5.0 Clutch rating across 36 verified reviews.

Technically, OST builds on modern frameworks (React, Node.js), headless CMS architectures (PayloadCMS, Drupal), and cloud infrastructure on AWS, with Cloudflare for edge/CDN, GitHub/GitLab for source control, and OpenAI/Anthropic LLM APIs for AI features. It operates two of its own products alongside services: AI Assistant 24/7 (a RAG-based, WCAG-accessible, multi-tenant customer-support chatbot used by clients such as Wild Boar ATV Parts and Council on Aging Martin County) and TapRelief (a free consumer wellness app with a 3D body picker). In April 2026 it launched a productized AI-Powered Ecommerce Chatbot sold in three tiers (Starter, Growth, Enterprise) with drop-in integrations for Shopify, WooCommerce, OpenCart, and Magento.

The business model is predominantly professional services with a recurring overlay. Revenue streams include project-based custom development (3–12 month build phases, quote-based pricing), ongoing maintenance retainers (most running $50K–$200K annually), white-label engineering for US agencies (offshore economics with US-time-zone presence), government RFP delivery (SAM-registered, Section 508/WCAG 2.2 AA conformant, WOSB-certified), and subscription licensing of its AI chatbot. Go-to-market is sales-led through a direct enterprise field-sales motion organized around three buyer doors — commercial businesses, agencies (white-label), and government/SLED — supported by content marketing (256 blog articles), SEO, free tools, case studies, and Clutch reviews. The firm emphasizes long-term retainer relationships, citing 5+ year average client tenure and a 12+ year longest engagement.
