AI chatbot development is the process of building conversational AI systems powered by large language models, retrieval-augmented generation (RAG) and multi-turn context management.
Pharos Production develops custom AI chatbots that go beyond template-based conversation flows. Our chatbots use retrieval-augmented generation (RAG), multi-turn context management and enterprise integrations to deliver intelligent conversations that resolve real business problems. We build chatbots for customer service, internal helpdesk, HR self-service, IT support, lead qualification and onboarding. Each chatbot connects to your knowledge base, APIs and backend systems, maintaining conversation context across sessions and channels. Multi-language support, sentiment detection and intelligent escalation to human agents come standard. Clients deploying our AI chatbots report 50-70% resolution rates without human intervention, 90% faster response times and consistent 24/7 availability across web, mobile, WhatsApp and Slack. Every chatbot includes analytics dashboards, conversation quality monitoring and continuous improvement through feedback loops.

Pharos Production collaborated with a taxi aggregator platform to develop a high-load ride-hailing application that connects passengers and drivers in real time. This platform consolidates various fleets and independent drivers into a single system, ensuring quick ride matching, live tracking and transparent pricing. Built on a cloud-native infrastructure, the solution offers low-latency interactions, reliable trip processing and scalability for operations at the city and regional levels.
Pharos developed a B2B platform that brings keyword research and search visibility analysis together with search data APIs, public-web collection and access through AI assistants. Our responsibility covered the full product.
Pharos Production has partnered with Sagas to create a location-aware social platform that enables users to capture, publish and explore geo-located timelapses over time. This system combines real-time data ingestion, large-scale media processing and map-centric discovery to transform physical locations into dynamic digital stories. Leveraging cloud-native infrastructure and event-driven architecture, Sagas allows users to document urban changes, natural evolution and personal moments tied to specific places. The result is a scalable social network where time and location are central to content discovery.

Pharos Production has been in business since 2013, with over 13 years of experience in custom software development. During this time, we have delivered over 110 applications for 200+ clients across 28 industries, including FinTech, healthcare, crypto and e-commerce. We are rated 5/5 on Clutch based on 107 verified reviews (2026).
Pharos Production provides six core service categories: AI Development (LLM applications, AI agents, machine learning and computer vision), Blockchain and Web3 (smart contracts, DeFi, tokenization on Ethereum, Solana, TON and other chains), FinTech Development (payment platforms, digital banking, KYC and AML integration), Software Development (mobile apps, web platforms, database design, UI/UX), Security and QA (code audits, penetration testing, smart contract audits, manual and automated testing) and Consulting (architecture design, MVP validation, startup consulting).
Pharos Production is headquartered in Las Vegas, Nevada, USA (5348 Vegas Dr, Las Vegas, NV 89108), with an engineering office in Kyiv, Ukraine (44-B Eugene Konovalets Str. Suite 201, Kyiv 01133). We work with clients worldwide and provide remote collaboration across all time zones. Visit our contact page for directions and scheduling options.
Pharos Production has a team of 90+ engineers, including software developers, blockchain specialists, QA engineers, DevOps experts, UI/UX designers, project managers and solution architects. Our founder, Dr. Dmytro Nasyrov, holds a PhD in Artificial Intelligence and leads the technical direction of all projects.
We serve a wide range of clients, from startups and product companies to mid-sized enterprises and large institutions. Our clients include crypto exchanges, FinTech providers (like Pleenk), healthcare organizations, sportsbook operators (like Pro Gambling), e-commerce platforms and SaaS companies. Pharos Production has worked with 200+ clients across 28 industries since 2013, adapting engagement models to match each client's stage, whether it is MVP validation for a startup or enterprise-scale development for an established business.
A custom software development company like Pharos Production assigns one dedicated engineering team that owns your product across multiple release cycles, instead of handing it off once a contract ends. Agencies more often rotate staff between clients and optimize for fast delivery over long-term product ownership.
Pharos Production keeps the same team on your codebase through 2-week sprints, so there is no re-onboarding cost each time you request a new feature.
Custom software development costs vary based on project scope and complexity. At Pharos Production, typical project ranges are: MVP development ($10,000-$25,000), suitable for startups validating a product idea; full-fledged production ($25,000-$50,000), for established businesses scaling a proven concept; and full-cycle development ($50,000-$80,000+), for complex enterprise-grade systems. These ranges include architecture design, development, QA testing and deployment. Hourly rates range from $50 to $99 depending on role and seniority. Final pricing depends on technology stack, number of integrations and engagement model (staff augmentation, dedicated team or project outsourcing).
Development timelines depend on scope and complexity. At Pharos Production, a typical MVP takes 2-4 months, a production-ready application takes 4-8 months and a complex enterprise system can take 8-12+ months. We use an agile methodology with 2-week sprints, delivering working increments after each sprint. Every sprint includes a retrospective, progress report and planning session for the next iteration. This approach ensures transparency and allows businesses to launch faster by prioritizing high-impact features first. Get a timeline estimate for your project.

Hiring a software development company offers faster time-to-market, lower upfront costs and access to specialized expertise without long-term employment commitments. According to Deloitte's 2024 Global Outsourcing Survey, 57% of companies outsource software development to access skills they cannot hire internally.
| Factor | In-house team | Software development company |
|---|---|---|
| Time to assemble | 3-6 months (recruiting + onboarding) | 1-2 weeks |
| Upfront cost | High (salaries, benefits, equipment) | Lower (project-based pricing) |
| Specialized expertise | Limited to who you can hire locally | Access to 90+ engineers across blockchain, AI, FinTech |
| Scalability | Slow (each new hire takes months) | Fast (scale up or down per sprint) |
| Long-term commitment | Full-time employment contracts | Flexible engagement models |
| Risk | High if key engineers leave | Company ensures continuity and knowledge transfer |
For businesses that need blockchain, AI or high-load architecture expertise, outsourcing to a specialized firm like Pharos Production reduces risk and accelerates delivery.
Pharos Production focuses on mid-to-large custom software projects with budgets starting at $10,000. We do not take on template-based websites, WordPress theme customization or short-term contracts under one month. We also do not provide non-technical staffing (marketing, sales or design-only roles). Our strongest fit is blockchain, FinTech and healthcare projects where security, compliance and high-load architecture are critical. For smaller projects or MVPs under $10,000, we recommend exploring freelance platforms or no-code tools as a more cost-effective starting point.
We use agile with 2-week sprints because it reduces the risk of building features that miss the mark. Each sprint ends with a working demo, a retrospective and a plan for the next iteration.
This means clients see progress every 14 days and can adjust priorities based on real results, not assumptions. We chose this approach after years of experience showing that rigid, fixed-scope contracts lead to scope creep, missed deadlines and products that do not match market needs by launch day.
Custom development is not the right choice in every situation. You should not hire a custom software company if: your problem is fully solved by an existing SaaS product (e.g. Shopify for e-commerce, Salesforce for CRM); your budget is under $10,000 and timeline is under 4 weeks; you need a simple landing page or marketing website (WordPress or Webflow is faster and cheaper); or you are still validating the idea and have not spoken to potential users yet.
In these cases, off-the-shelf tools or no-code platforms offer better ROI. Custom development makes sense when you need unique workflows, regulatory compliance, high-load architecture or competitive differentiation that packaged software cannot provide.
