Answers to whatyou’re wondering.

We work with startups, small and mid-sized businesses, and e-commerce brands around the world — from first-time founders validating a product idea to established companies with 50+ employees modernizing their tech stack.

A focused MVP typically takes 8–12 weeks. More complex platforms with integrations, custom AI models, or multiple user types can take 3–6 months. We provide a detailed timeline before work begins.

Yes. After launch, we provide ongoing support including performance monitoring, security patches, feature updates, and bug fixes.

Security is built into our process from day one — end-to-end encryption, secure authentication, and role-based access controls as standard. For regulated industries, we build to meet HIPAA, GDPR, and other compliance requirements.

Both. We work with businesses of every size — from a founder validating an AI-powered MVP to an established company automating operations with custom models.

We use Kotlin for all new Android projects — it’s Google’s preferred language, produces cleaner code, and has better tooling support. We also maintain and modernize Java-based Android apps, and can migrate legacy Java codebases to Kotlin as part of a modernization engagement.

We define a target device matrix at the start of every project — covering the device brands, screen sizes, and OS versions that represent your actual user base. We test against this matrix throughout development and use responsive layouts and adaptive UI patterns to ensure consistent behavior across it.

Yes — and we do it regularly. We can build separate native apps for each platform, or use React Native or Flutter to share a codebase across both. We’ll recommend the right approach after understanding your priorities around performance, timeline, and budget.

A focused MVP typically takes 10–14 weeks. More complex apps take 4–6 months. Timeline depends on feature scope, backend complexity, and the number of third-party integrations involved.

We primarily develop in Swift — Apple’s modern, fast, and safe programming language. For legacy projects or specific use cases, we also work in Objective-C. We use SwiftUI for modern interface development and UIKit where broader device compatibility is required.

A focused MVP typically takes 10–14 weeks from kickoff to App Store submission. More complex applications with custom backends, integrations, or advanced features take 4–6 months. We scope every project individually and give you a detailed timeline upfront.

Yes — we design and develop with the full Apple device family in mind. Whether you need iPhone-only, universal iOS (iPhone + iPad), or an Apple Watch companion app, we scope and build for all the surfaces your users are on.

Absolutely. We take on iOS modernization projects regularly — migrating Objective-C to Swift, updating UI to SwiftUI, adding new features, or rebuilding from scratch when the existing codebase is beyond saving. We’ll audit your current app and give you an honest recommendation.

A website primarily displays content for visitors to read. A web app is interactive software that users log into, manipulate data within, and use to accomplish tasks — like a project management tool, e-commerce platform, or customer portal. We build web apps, not websites.

Our standard frontend stack is React or Next.js. Our backend is typically Node.js or Python (Django/FastAPI), depending on the use case. We use PostgreSQL or MongoDB for databases, and deploy on AWS, GCP, or Azure. We recommend the right combination for your specific project during our discovery phase.

A focused MVP with core functionality typically takes 12–16 weeks. Full-featured products with complex business logic, integrations, and custom dashboards take 4–8 months. We provide a detailed timeline after scoping your project.

Yes — completely. All source code, documentation, and infrastructure configurations are fully owned by you at the conclusion of the project. We don’t retain any IP or create any dependencies on Zentury to keep your app running.

Data requirements depend heavily on the type of AI system you’re building. Some approaches require large datasets; others work well with a few thousand examples. Transfer learning and foundation models have dramatically reduced the data needed for many tasks. We’ll assess your current data situation in our discovery phase and tell you honestly whether it’s sufficient — or what you’d need to collect first.

Off-the-shelf AI tools are general-purpose — they’re not trained on your data, they don’t know your business context, and they can’t be optimized for your specific performance requirements. Custom AI development means building systems that learn from your data, reflect your domain knowledge, and improve based on your feedback — giving you a genuine competitive advantage rather than the same tool your competitors are using.

It depends significantly on data availability, model complexity, and integration requirements. A focused AI feature integration (like adding a recommendation engine to an existing app) might take 8–12 weeks. A full custom AI platform with data pipelines, model training, and production deployment typically takes 4–8 months.

Yes — this is one of the most common engagements we take on. We build AI capabilities as APIs or microservices that integrate cleanly into your existing systems, or we work directly within your codebase to add intelligent features to an existing web or mobile application.

It depends on your use case, data sensitivity, and cost tolerance. GPT-4 and similar APIs are excellent for general tasks with no data privacy concerns. Open-source models (LLaMA, Mistral) are better when you need data privacy, lower inference costs, or the ability to fine-tune extensively. We’ll analyze your requirements and recommend the right approach — not the most expensive one.

RAG is a technique that gives your LLM access to a knowledge base — your documents, data, or database — at inference time. Instead of relying purely on what the model learned during training, it retrieves relevant context and uses it to generate accurate, grounded responses. Most production LLM applications benefit from RAG because it dramatically reduces hallucination and keeps responses up to date.

Hallucination prevention is a systems problem, not just a model problem. We combine RAG (to ground responses in real data), output validation (to check responses against known facts), confidence scoring, and human-in-the-loop escalation for low-confidence responses. We also build evaluation pipelines that continuously test for factual accuracy on your specific domain.

A focused LLM integration — like a RAG-powered Q&A system for your documents — can be delivered in 6–10 weeks. A full custom LLM application with fine-tuning, evaluation infrastructure, and production deployment typically takes 3–5 months.

Traditional AI systems analyze and predict based on existing data — classifying, ranking, or detecting. Generative AI creates new content — text, images, code, audio — based on patterns it has learned. The two approaches are complementary and are often combined in production systems.

Quality control is a core part of our Generative AI engineering. We combine automated checks (coherence, factual validation, style compliance), human review workflows for sensitive applications, and continuous evaluation frameworks that measure output quality over time. We also fine-tune models specifically to improve quality on your content type and domain.

Yes — with fine-tuning and prompt engineering. We expose the model to examples of your content, develop detailed style and tone specifications, and iterate until the generated output consistently reflects your brand voice. The process takes iteration, but the results can be remarkable.

A focused text generation system — like a product description generator or email drafting tool — can be built in 8–12 weeks. More complex multimodal or multi-stage generation systems with custom quality control infrastructure typically take 3–5 months.

Rule-based chatbots follow scripted decision trees — they only work when users follow a predicted path. AI chatbots use natural language understanding to handle the full range of how humans actually express themselves — including questions the scripts never anticipated. They’re more flexible, more useful, and dramatically better at handling real conversations.

We use a combination of fine-tuning and Retrieval-Augmented Generation (RAG). We ingest your product documentation, support history, FAQs, knowledge base articles, and any other relevant content — building a knowledge retrieval system and training the model to give accurate, on-brand responses based on that material.

Yes — integration with your existing systems is a standard part of what we build. We commonly integrate with Salesforce, HubSpot, Zendesk, Intercom, Freshdesk, and custom CRM or order management systems. The chatbot can look up account information, log interactions, create tickets, and update records in real time.

We design explicit escalation logic for every chatbot we build. When the bot isn’t confident in its response, or when the user requests a human, it hands off to a live agent — with full conversation history — so the customer never has to repeat themselves. The escalation triggers, messaging, and handoff workflow are all designed specifically for your business.

GPT-4o is the best balance of capability and cost for most production applications. GPT-4 Turbo is appropriate for the most complex reasoning tasks. GPT-3.5-Turbo is viable for high-volume, simpler tasks where cost efficiency is critical. We analyze your use case and recommend the right model — and often design architectures that use different models for different parts of the workflow.

By default, OpenAI does not use API inputs to train models. For applications with strict data privacy requirements — healthcare, legal, financial — we can architect solutions using Azure OpenAI Service (which has enterprise data privacy guarantees and HIPAA BAA availability) or locally-hosted open-source alternatives.

Yes — this is one of our most common engagements. We build RAG systems that give GPT access to your product catalog, documentation, support content, and knowledge base — so it can answer specific questions about your products and services accurately, rather than generating plausible-sounding but incorrect answers.

OpenAI API costs depend on the model you use and the volume of tokens processed. We design architectures with cost efficiency in mind — caching, context compression, model tiering — and provide cost projections at your expected usage volume as part of our project scoping.

We generally recommend against relying on page builders for custom WordPress development — they add significant performance overhead, create vendor dependency, and make long-term maintenance harder. We build custom Gutenberg blocks and themes that give you the same editorial flexibility without the downsides. If you have a specific business reason to use a page builder, we’ll discuss the trade-offs honestly.

WordPress is the most widely attacked CMS, so security requires active attention. We harden the installation at setup (hardened wp-config, restricted file editing, proper permissions), configure a web application firewall, implement two-factor admin authentication, set up automated backups, and apply updates on a regular maintenance cycle.

Yes — WordPress performance optimization is a standalone service we offer. We audit your current site, identify the top performance bottlenecks (usually slow plugins, unoptimized images, poor caching, or an underpowered host), and implement targeted fixes. Most sites we optimize see Core Web Vitals improvements within two weeks.

Yes — that’s a core requirement for every WordPress site we build. We configure the CMS for non-technical editors, build custom blocks that make content editing straightforward, and provide training for your team on how to use what we’ve built.

Premium Shopify themes are a good starting point for small stores or quick launches. But they have limitations: everyone on the same theme looks similar, performance can suffer from unused features, and customization options are constrained by what the theme supports. A custom Shopify theme gives you full control over design, performance, and functionality — and for a growing brand, the investment pays for itself in conversion rate improvements and brand differentiation.

Yes — migration is a standard service we provide. We migrate your product catalog, customer records, order history, and SEO URL structure to Shopify, with thorough data validation before and after. We also manage the technical SEO migration to protect your search rankings during the transition.

Yes. We build custom Shopify Plus experiences including checkout.liquid customization, Shopify Scripts for automated discounts and shipping logic, multi-store configurations, and B2B wholesale functionality. Shopify Plus is the right choice for stores processing significant monthly revenue who need the advanced customization and SLA it provides.

Shopify has some SEO limitations by default — duplicate content issues, URL structure constraints, and canonicalization challenges. We address all of these as part of our standard build process: clean URL structures, proper canonical tags, schema markup, sitemap configuration, and page speed optimization. Your Shopify store should be technically sound for SEO from launch day.

Webflow is the best choice for design-conscious brands, startups, and marketing teams that need editorial independence and design quality — without the technical overhead of a custom-coded site. It’s ideal for marketing sites, landing pages, portfolios, and content-driven sites. It has limitations for highly complex web applications or large e-commerce operations with complex requirements — and we’ll tell you honestly if your use case pushes beyond what Webflow does well.

Yes — editorial independence for your team is a core goal of how we build. We design CMS schemas that make content management straightforward, configure the Webflow Editor for non-technical users, and provide training and documentation so your team is genuinely confident managing the site.

Webflow offers better performance out of the box, significantly better design freedom, simpler hosting and security management, and a better CMS editing experience for non-technical users. WordPress has a larger plugin ecosystem, more mature e-commerce (WooCommerce), and more flexibility for very complex custom functionality. The right choice depends on your specific needs — and we’re happy to help you think through the decision.

Webflow has its own managed hosting — fast, reliable, and included in Webflow’s plans. We configure and manage your Webflow hosting as part of the project, and your team manages the ongoing plan subscription directly with Webflow. This is one of the operational advantages of the platform: no separate hosting bills or server management.

HubSpot is modular — Marketing Hub, Sales Hub, Service Hub, CMS Hub, and Operations Hub are each licensed separately and have Starter, Professional, and Enterprise tiers. The right combination depends on your team size, workflow complexity, and budget. We assess your requirements and make a specific recommendation as part of our discovery process — we won’t recommend more than you need.

Yes — CRM data migration is a standard part of HubSpot implementation projects. We map your existing contact, company, and deal data to HubSpot’s properties, clean up data quality issues in the process, and validate the import before go-live. We also migrate historical email activity and customer interactions where the source system supports it.

HubSpot has a large native integration library covering most common business tools. For systems not in the native library, we build custom integrations using HubSpot’s API — bidirectional data sync, webhook-triggered automations, and custom data mappings that reflect how your specific tools need to exchange information.

A clean HubSpot setup with CMS website, core automation, and CRM configuration typically takes 8–12 weeks. More complex implementations involving custom integrations, data migrations from multiple systems, or large automation buildouts take 3–5 months. We scope each project after a discovery session and give you a realistic timeline upfront.

We work with startups, small to mid-sized businesses, and enterprise clients across industries including e-commerce, healthcare, fintech, education, logistics, and more. Whether you’re launching a new product or optimizing existing operations, we tailor our solutions to your specific goals.
