PieStack

PieStack is a development and branding agency based in Lahore, Pakistan, founded in December 2024. The company emerged from the merger of two earlier entities—Bluhat (founded 2021, focused on marketing and sales) and CodeViz Technologies (launched 2022, custom software and SaaS development). PieStack operates with a stated focus on combining full-stack software development with strategic brand thinking, positioning itself as a hybrid shop that handles both product and go-to-market from one team. The agency has completed 100+ projects across industries including fintech, ecommerce, education, additive manufacturing, and sports. It maintains offices in Lahore and Maryland, USA.

Services and capabilities

PieStack organizes its offerings across three pillars: 50% development, 30% branding, and 20% strategy and growth. On the development side, the company builds AI-powered products, custom web and mobile applications, MVPs, ecommerce platforms, and product strategy from concept through launch. The AI work is specific: LLM-powered applications using OpenAI, Claude, and Anthropic; custom chatbots with OpenAI Assistant API or Vapi; RAG-based search engines; and workflow automation. One completed project, L3AD, demonstrates this approach—a manufacturing platform that reduced manual quoting effort by 70% and generates standard quotes in 11 seconds using AI trained on historical production data.

On the branding side, PieStack handles brand identity, digital marketing, Instagram and TikTok content, influencer programs, email marketing, meta ads management, and website design. The company also offers product photography and positioning strategy. A third project, Minimal Space (furniture e-commerce), saw a 220% increase in Shopify revenue, 11k+ Instagram follower growth, and 4.5x ad ROAS on Meta campaigns.

For emerging products, PieStack claims to move from idea to functional MVP without overbuilding. The company structures pricing via an AI-powered quote tool on its website for instant estimates, though engagement specifics aren't detailed in the source.

Notable work

Three projects are featured prominently. L3AD (additive manufacturing) is a full-scale manufacturing platform built for a 3D printing bureau in Reutlingen, Germany. The core challenge was structuring and cleaning legacy data; after iterations and accuracy testing, Phase 1 launched in early 2026. The platform covers file upload to order shipment, operates 24/7, and reduced manual effort by over 70%.

Check2Learn (education technology) is an AI-powered learning platform where students submit answers in typed, document, or handwritten formats, and AI evaluates responses instantly. Teachers can identify learning gaps and present content in alternative formats. Built with LangChain and LangGraph, the system is not a chatbot bolted onto an LMS but an evaluation engine driving every interaction.

Minimal Space (furniture retail) leveraged PieStack's combined development and branding services. The brand sells handcrafted furniture with minimalist aesthetics. Results: 220% Shopify revenue increase, 11k+ Instagram follower growth, and 4.5x Meta ad ROAS.

Other named clients include Haison Skin (K-beauty brand with TikTok and Instagram content work), JootiShooti (handmade footwear, local Pakistan production), and SportsBall (fantasy sports platform for PlayDFS, delivered in 3 months with full UI/UX design and mobile/backend development).

How they work

PieStack frames its approach around three core values: visionary thinking, action-oriented execution, and tech alignment. The company emphasizes accountability to outcomes, not just deliverables, with stated focus on clear process and honest communication. An instant AI quote tool is available on the website for quick estimates. The source does not specify retainer models, sprint structures, or communication cadence. Project timelines vary—SportsBall was completed in 3 months; L3AD shipped Phase 1 in early 2026 after data structuring and iteration.

Team and credentials

No specific team size or founder names are disclosed in the source material. The company does not mention ISO certifications, SOC 2, GDPR compliance, or partner badges (AWS, Google, Shopify Plus). It claims 5+ years of experience collectively (counting the predecessor entities Bluhat and CodeViz) and 75+ happy clients as of the source publication date. Awards are mentioned generically as "3 Awards achievement" with no specifics provided.

Technologies in use include React, Next.js, Python, Django, PostgreSQL, Stripe, Scikit-learn for the L3AD project; LangChain and LangGraph for Check2Learn; and integrations with OpenAI, Claude, Cohere, Vapi, ElevenLabs, Midjourney, and Stable Diffusion for AI work. The company explicitly lists support for frameworks including Windsurf and Cursor for developer tools.
