TechnoBlick is a software and AI company headquartered in Islamabad, with a second office in Lahore, Pakistan. Founded in 2020 and registered as TechnoBlick (SMC-Private) Limited, we have delivered 160+ projects for clients across Pakistan and 30+ countries worldwide, with 95.94% client satisfaction. WHAT WE BUILD Web development. Marketing sites, e-commerce platforms and custom web applications, usually paired with bespoke admin systems for inventory, orders, catalogues and content. We build on modern stacks and hand over clean, documented code. Mobile development. Native iOS and Android applications as well as cross-platform builds, from consumer apps to internal tools with offline capability and third-party integrations. Custom software. Internal platforms, dashboards, booking and scheduling systems, multi-tenant portals, and systems integration connecting tools that were never designed to talk to each other. AI and automation. Agentic systems, AI voice agents, transcription and document processing pipelines, and workflow automation. Our AI work is grounded in real business processes rather than chatbot demos - one recent build combines GPT-powered transcription, AI-graded assessments and a human review gate before any certificate is issued. UI/UX design. Product design, design systems and interface work, delivered alongside engineering rather than thrown over a wall to it. SEARCH AND DIGITAL MARKETING Our search practice is full-service, not technical-only. Traditional SEO. Technical SEO and site architecture, on-page and content optimisation, keyword and competitor research, local SEO for businesses with physical presence, programmatic SEO for sites that scale across locations or categories, and conversion rate optimisation so traffic actually turns into enquiries. Authority building. Link building, digital PR, directory and citation work, and review generation. We build authority the way it holds up over time - branded anchors and real editorial placements rather than bulk link buying. AI search. This is where search is moving, and it is a different problem from ranking. We work on Generative Engine Optimization and Answer Engine Optimization, structuring content, entities and schema so a business gets cited inside Google's AI Overviews and inside assistants like ChatGPT, Perplexity and Gemini. A page can rank first and still be invisible in the answer a buyer actually reads. We build for both. Paid and social. Google Ads management on fixed fees rather than a percentage of ad spend, plus social media marketing and content. HOW WE WORK Nineteen people, deliberately senior. The engineer who designs a system is the engineer who builds and owns it. There is no layer of account managers between you and the people writing code, and no junior handoff after the pitch. Engagements typically run 6 to 16 weeks. We open with a paid one-week scoping phase covering scope, success metrics and architecture, so both sides know exactly what is being built before anyone commits to a number. From there we ship in two-week sprints with weekly demos - progress is something you see rather than something you are told about. WHAT MAKES US DIFFERENT We build and operate our own SaaS product. Scaliam is designed, engineered and supported entirely in-house. Running a product in production means we deal directly with the reliability, retention, onboarding and support problems that most agencies only advise on. We stay accountable after launch. We run ongoing SEO retainers for several platforms we originally built, including e-commerce and healthcare systems, so we are measured on whether a product performs months later, not just on whether it shipped on time. We are honest about what we do not have. We tell clients when a market is not winnable in the timeframe they want, and we do not claim certifications or partner badges we have not earned. Every client site we name can be visited and verified. COMMERCIAL TERMS Fixed fees, quoted upfront after scoping. We do not charge a percentage of ad spend on marketing engagements, which keeps our incentives aligned with results rather than budget growth. Clients retain permanent ownership of everything - code, hosting, domains, ad accounts and analytics. If an engagement ends, all of it stays with the client. No proprietary platform to migrate off, no lock-in. INDUSTRIES We work across 12 industries: healthcare, education, e-commerce and retail, immigration and study-abroad, fintech and financial services, real estate, restaurants and hospitality, fitness and wellness, construction, logistics, legal and taxation, and marketplaces and SaaS.

Aimprosoft

Engineering Partner Accountable to the Outcomes

Aimprosoft is a product engineering and AI implementation partner for companies that need technology to produce measurable business outcomes, not just working software. We build custom software platforms, SaaS products, and mobile apps, and we implement AI in production, including LLM integrations, RAG pipelines, intelligent document automation, and conversational assistants, with adoption tracked rather than left to a pilot that never ships. What sets us apart is accountability. We put KPI commitments in writing before Sprint 1, covering targets such as lead time reduction, defect rate, and planning accuracy. Before any AI investment, our AI audit gives clients a GO/NO-GO recommendation grounded in the evidence, not a sales pitch dressed up as a roadmap. In 20 years, we've grown from 3 people to a team of 200+ people, delivered work across 26 industry verticals, and built partnerships with 650 clients in 28 countries, some spanning 16 to 17 years. 72% of clients return for their next major initiative, more than double the industry average, because they get a business partner instead of a resource pool. Core services: - Custom product and platform engineering: web, mobile, cross-platform, cloud, DevOps, and QA - AI in production: LLM and RAG integrations, intelligent document automation, computer vision, NLP, and predictive analytics - AI audit and AI strategy consulting - Legacy system modernization - Embedded, long-term engineering teams and staff augmentation

We focus on careful architecture, direct communication, and systems that keep working under real operational pressure.

Anadea

Engineering what comes next

Code is no longer the bottleneck. Strategy, speed, and the right architecture are. How you engineer your product defines how far it can go. Founded by engineers in 2000, Anadea brings a builder's mindset to every project. The company operates as a one-stop-shop for product ideation, creation, and maintenance, guided by direct involvement in clients' success. Anadea is trusted by lasting partnerships. For over a decade, they have helped platforms like Visdeal (a top sector performer) and StreetEasy (part of Zillow Group). Today, StreetEasy is New York's leading real estate service, attracting over 180 million visits annually. Transparency is a standard practice for Anadea, and verified client references are readily available as part of the due diligence process. AI-ACCELERATED ENGINEERING Launch a new product and get to market 5x faster with AI-accelerated engineering AI-accelerated development lets us ship your product in weeks instead of months. But speed means nothing if the product can't scale, so we build every MVP on architecture that's ready for growth. It all starts with a two-week Discovery sprint at a fixed price. You walk away with an architecture, a roadmap and a clear estimate before committing to anything bigger. LONG-TERM PARTNERSHIP Get a strategic engineering partner for long-term product growth For 12 years, StreetEasy has trusted us as its engineering partner. Together, we’ve evolved its platform from a monolith into a system that handles 180 million annual visits and runs 33 times faster. That doesn't happen when you only write code. We take ownership of technical direction and help established teams move faster with confidence. OPERATIONAL AI Automate operations and multiply team capacity with AI For a US law firm, we built AI that processes thousands of pages of medical records in minutes instead of a week. For a $10B European private equity fund, we deployed five AI agents that screen 5,000 opportunities in hours. Most companies want automation but don't know where to start. We figure that out with you and handle the entire technical side.

What We Do: We provide end-to-end software development services across the full product lifecycle: from early-stage idea validation and MVP development to scaling complex enterprise platforms. Our core services include: - Custom web and mobile app development - UI/UX design and product design - AI/ML integration and custom AI development - Cloud engineering and DevOps - SaaS development and consulting - Dedicated development teams and staff augmentation - UX audit and product modernization We work across industries including fintech, insurtech, logistics, edtech, e-commerce, healthcare, real estate, and travel & hospitality. How We Work: At Brights, we act as co-creators — not just executors. Our specialists bring ideas, initiative, and ownership to every engagement. We focus on understanding the business goals behind every project, not just the technical requirements. That means our teams actively contribute to product decisions, suggest improvements, and help clients think strategically about their technology. We offer flexible engagement models to fit different project stages and business needs: Time & Materials, Dedicated Team, Fixed Cost, and milestone-based billing.

And internally, we invest in each other just as much as we invest in client projects. Strong teams build strong products. 2. High standards, always. We are selective in hiring and demanding in delivery. Our specialists are celebrated for going beyond — because we genuinely believe that transcending limits is what separates good software from great software. 3. Co-creators, not doers. Our average client relationship lasts over three years. That's not an accident — it's the result of treating every engagement as a long-term partnership, not a transaction. Trusted by Leading Brands: We've collaborated with globally recognized organizations including Mastercard, Microsoft, Pepsi, and Danone, as well as Fortune 500 companies such as Coca-Cola, McDonald's, and Kimberly-Clark.
