White Prompt

White Prompt is a Brazil-based software development agency with 120 senior developers operating in U.S. time zones. Founded in 2022 (per copyright), the company positions itself as a nearshore partner for American tech companies, emphasizing architecture, design, and development across the full software lifecycle. They've logged over 1 million hours on 100+ production projects, working with names like YieldStreet, Angie's List, Common Desk, and Troops.ai.

The agency runs a branded MVP process called the 5-D Method—Discovery, Design UI, Design Architecture, Develop, and Delivery—claiming to ship MVPs in 8 weeks rather than the typical 16. Whether that timeline holds depends on scope, but the process itself is explicit: align vision, design user flows, architect for scale, code with AI assistance, then launch. They also offer fixed-scope package solutions (AI Insight Vault for data analysis, Scale Guard for performance tuning, Data Poirot for KPI collection) that bundle process with tooling and a locked cost.

Services and capabilities

White Prompt organizes around six horizontal pillars: Architecture, Product Design, Development, DevOps, Quality Assurance, and an emerging AI practice. Their architecture team has 20+ years of cumulative experience. They design and build serverful or serverless systems, handle technical due diligence via Proof of Concept, and specialize in event-driven microservices, data engineering, and blockchain. Their product design function includes UX audits, user testing, and branding work. Development covers the coding itself, complemented by DevOps services: infrastructure-as-code (Terraform, Ansible, Puppet), CI/CD pipeline setup, monitoring and alerting, performance optimization, and infrastructure cost reduction.

QA appears to span manual and automated testing. The emerging AI practice includes natural language processing, machine learning, and computer vision; they also market an "AI Insight Vault" product that processes data within your own cloud for privacy, and "Tailored4U," which predicts user preferences to drive sales.

They also provide IT consulting and strategy services, implied through their positioning on discovery and architecture phases. All services are billed as part of an end-to-end offering; they avoid positioning as a commodity coding shop.

Notable work

Their portfolio includes YieldStreet (a digital wealth management platform, architecture, development, DevOps, QA), Angie's List (crowd-sourced reviews platform, architecture, development, QA), and Aquto (mobile engagement via data sponsorship, R&D and development). Other named projects: Talent Acquisition Automation Platform (fully automated job candidate integration), Wine & Spirits publication, ArtistOnGo (beauty industry staffing), Ashiwea (HR/sales loyalty), Lokals (travel marketplace), Virtual Terms (contract creation), Aleign (Agile project management), Olive (eco-friendly e-commerce logistics), and Common Desk (coworking space booking app).

Client testimonials come from Common Desk CEO (Nacho Cidre led on-site strategy before delivery), Troops.ai CTO (praised autonomous execution and existing-team integration), Soyouapp CEO (noted time-zone alignment benefits), Analytics Fire CEO (deep React.js expertise), CabinetM Founder (helped build early platform), SalsaMobi Founder (modern tech stacks like Scala and React), and Ubuntu Founder (called them "integral partner from inception through growth").

How they work

White Prompt uses a discovery-first model. They start with stakeholder interviews, technical analysis, and proof-of-concept sprints to validate architecture choices before committing to a build. Their 5-D Method bundles this into an 8-week timeline for MVPs. For ongoing work, testimonials suggest they either embed (on-site or U.S. time-zone sync calls) or integrate into existing teams. They offer a free 30-minute consultation and longer 3-hour paid engagement options. Pricing is not disclosed in the source, though they emphasize fixed-scope packages with transparent timelines and costs for their bundled solutions.

Team and credentials

White Prompt employs 120 experts, all English-speaking and available during U.S. business hours (nearshore advantage). Their architects claim 20+ years of combined experience in systems design. No formal certifications (ISO 27001, SOC 2, etc.) are mentioned in the source material. No partnerships with major cloud providers are stated, though infrastructure work involves AWS, GCP, and Azure implicitly. Founder and lead named as Nacho Cidre, mentioned in testimonials as the point person who spent a week at Common Desk's office in Texas.
