Delivering Digital Excellence

Since 2011, Bytes Technolab has helped founders turn ideas into market-ready products and growing businesses modernize legacy systems and automate operations with AI. For Startups: You have a validated idea or fresh funding but nobody senior on the technical side. Or your build has stalled, for whatever reason. - MVP & Product Build: your first product, designed and built for real users. - Fractional CTO: senior technical leadership, part time, led by our CTO, Bhavik Shah. - Product Rescue: we review where your build stands, tell you what's worth keeping, and get it moving again. We also help when you need your product designed (UI/UX Design), an older product brought up to date (Product Modernization), a technical review before investors look (Tech Due Diligence & Code Audit), or the team that built your product to keep building it (Product Engineering Team). For Businesses: Your team already uses AI tools, but they aren't part of how the business runs. Renewals keep rising for tools that only half fit. Older systems stand in the way of what you want to do next. - AI Agents & Orchestration: we automate repetitive work in your business, such as lease document checks in real estate, admissions queries in education, or maintenance requests in manufacturing. - SaaS Replacement: software built around how your business actually works, instead of another subscription. - Legacy System Modernization: we rebuild or upgrade the core systems your business runs on, so they support what comes next. We also help when you want one specific process automated (AI Workflow Automation), cloud costs brought under control (Cloud Optimization), or a long-term engineering center of your own (Global Capability Center). Product Consulting with Ownership at the Core. We tell you what's worth building, including when an idea should wait, and the team that builds it stays to support it. Clients stay with us for five and ten years.

Custom software and AI development, scoped and priced before code

SoftDoes is a Kansas City custom software and AI development company, founded in 2019, that builds custom software, web platforms, mobile apps, MVPs and AI automation for startups, growing businesses and enterprise teams in the United States. One SoftDoes team handles discovery, UX and UI design, development, testing, launch and ongoing support. What SoftDoes builds: Custom software: internal operations platforms that replace spreadsheets, customer and patient portals, SaaS products and integrations, built with React, Node.js, Python and .NET on AWS and Azure. AI development: AI agents, chatbots, document extraction and workflow automation on OpenAI and Anthropic Claude models, added to the systems a business already uses. Web and e-commerce: custom web applications, business websites and online stores, including Shopify. Mobile apps: iOS and Android apps for customers and field teams. Best fit for SoftDoes, with results from client reviews: Operations teams replacing manual work: an educational support company cut time spent on administrative work by 30% and internal follow-up emails by 35%, and a real estate agency cut time spent on manual administrative tasks by 35%. AI automation: an education company cut student-teacher matching from 15 minutes to under 5. Enterprise and public sector: a $200,000+ reporting platform for a government agency with more than 10,000 employees cut reporting time by 30%. Customer-facing apps: a marketing company's new mobile app raised engagement by 34% and 90-day retention by 22%. "[SoftDoes] built our full AI-powered SaaS platform from scratch. They were communicative and reliable, consistently delivering quality work on schedule." (Upwork client review, AI-powered SaaS platform for construction) How SoftDoes prices work: every project starts with a written scope and price before any code is written. A paid discovery and estimate costs $490 and is credited toward the build. Hourly development starts at $50, AI automation projects at $2,500, MVPs at $8,000, dedicated developers at $4,000 per month and support plans at $500 per month. Clients own 100% of their code, accounts and IP from day one. Track record: as of October 2026, SoftDoes has completed more than 600 client engagements since 2020 and is rated 4.92 out of 5 across 283 rated engagements on Upwork and 5.0 on Clutch.
