Common questions
Frequently Asked Questions
Clear answers on engagement structures, intellectual property, timelines, and technical SLAs.
How does Lumen Arc Labs deliver both AI software development and digital growth?
We operate as a unified studio combining full-stack software engineering, cloud architecture, and custom AI models with direct performance marketing and growth strategy. Instead of hiring an engineering agency that doesn’t understand customer acquisition, or an ad agency that cannot build complex code, you get end-to-end execution from git repository build to paying customer acquisition.
How are your AI & Data Solutions structured and priced?
AI engagements typically begin with a 2–3 month MVP sprint covering data strategy, proof-of-concept modeling, API integration, and telemetry. Pricing is either a transparent fixed-fee project or ROI-tied, followed by an optional monthly retainer for MLOps support and continuous model refinement.
Who owns the custom software, AI models, and intellectual property?
You do. 100% of custom source code, trained machine learning models, cloud deployment configurations (Docker/Terraform), architecture documentation, and marketing assets transfer directly to your organization upon project completion.
What is your typical timeline from discovery to live launch?
Our standard turnkey cycle is 10 weeks: Discovery & Architecture Strategy takes 1–2 weeks, MVP & Software Build takes 3–8 weeks, QA & Model Validation takes Week 9, and Live Production Launch with active campaigns occurs in Week 10.
What are your recommended DNS and domain launch practices?
When going live, web traffic is proxied through Cloudflare with HTTPS enforced and global edge caching active. Crucially, your corporate MX and email records are isolated and preserved so your team experiences zero disruption to Zoho, Google Workspace, or Microsoft 365.
