They're clearly experienced, understand what's needed, and are truthful and honest about it. With Ptolemay, I don't have to worry about the ongoing process since all updates are easy to access.

      Анастасия Головенко's Review Sourced from Google

      We cooperate with Ptolemay for the last couple of years in terms of outstaffing demands. As we have already worked on more than 6 big projects, they have proven themselves as a reliable partner that provide high quality developers. Despite the difficulty of the position we need, they are always ready to involve their team to help us cover the demand. Even though any cooperation tend to have its own issues and misunderstanding, the Ptolemays’ team has always been open for resolving problems and finding compromise

Frequently Asked Questions

What is the total cost of AI development?

The total cost of AI development ranges from $50,000 to over $1 million, depending on whether you are buying an off-the-shelf artificial intelligence solution or hiring a custom AI development company. 

Typical ranges are: 

Project ScopeTypical AI Use CasesCost Range (USD)Expected Timeline
Pilot or Proof of Concept Simple chatbots, internal assistants, early prototypes $15,000–$40,000+1–2 months
MVP or Mid-Level Build Automation tools, analytics systems, small GenAI solutions $50,000–$150,000+2–4 months
Advanced Custom AINLP pipelines, computer vision, multi-agent workflows$150,000–$500,000+4–6 months
Enterprise-Scale AIPlatform-level AI, regulated systems, high-volume GenAI$200,000–$1,000,000+6–12+ months

Usual cost drivers include: 

  • AI model complexity: 30% to 40% 
  • Data collection and preparation: 15% to 25% 
  • Infrastructure and tech stack: 15% to 20% 
  • Tools choice (open-source vs proprietary): 5% to 15% 
  • Long timelines and extended engagement: 5% to 10% 
  • Regulatory and compliance work: 5% to 10% 
  • Testing, validation, maintenance: 10% to 15% 

What is the timeline from signing the contract to the first live use case?

The timeline from contract signing to the first live AI use case typically ranges from 2 to 18+ months, depending on project scope and complexity. Most AI agencies deliver value in phases, starting with a live pilot before expanding. 

AI development timeline from contract to first live use case: 

Project TypeTypical Use CaseTime to First Live Use Case
Proof of Concept (PoC) or MVPSimple chatbot, internal assistant, RAG prototype4–8 weeks
Mid-sized custom AI solution Invoice automation, CRM agent, analytics tools4–6 months
Enterprise AI platformMulti-agent systems, regulated workflows, supply chain AI9–18+ months

The first live use case is usually a limited but real deployment, not a full rollout. 

Top AI development companies start with a PoC or MVP to validate data, workflows, and adoption. Enterprise AI takes longer due to security, compliance, integration, and operational readiness.

What is the typical ROI for AI solutions?

Across enterprise and B2B use cases, studies consistently show an average return of about 3.5× for every $1 invested, with top performers reaching up to 8× returns.  

Most organizations see meaningful ROI within 12–18 months, and many deploy their first production AI use case within 6–12 months, which is when returns usually begin. 

What is the difference between Generative AI and non-GenAI?

Generative AI (GenAI) uses the patterns it has learned to create something entirely new that didn't exist before. In contrast, non-gen AI is designed to analyze, classify, and predict based on existing data.

  • Use GenAI when you need innovation and synthesis. If you need to brainstorm marketing copy, summarize a 50-page transcript, or generate a prototype logo, you want the "creator."  
  • Use Non-GenAI when you need accuracy and consistency. If you are predicting stock prices, diagnosing a disease from an X-ray, or calculating the fastest route home, you want the "judge" who focuses on facts and patterns. 

Take a look at their main differences: 

AreaGenerative AI (GenAI)Non-GenAI (Traditional / Discriminative)
Core functionGenerates new contentAnalyzes or predicts from existing data
Typical outputText, images, audio, video, code, or summariesA label, a number, or a probability
FlexibilityHighMedium to low
PredictabilityLowerHigher
Risk profileHallucinations, data leakageModel bias, data quality
Best use casesAssistants, copilots, content, exploration Fraud detection, forecasting, optimization
Governance needsHighModerate

Are there regulations on AI?

As of 2026, there is no single U.S. federal AI law. AI studios operate under a mix of existing federal rules enforced by agencies like the FTC, SEC, EEOC, and CFPB, which apply consumer protection, privacy, and anti-discrimination laws to AI systems.  

Federal policy is currently shaped mainly by Executive Orders and agency guidance rather than a comprehensive statute. 

States are moving faster. Colorado has passed strict rules for high-risk AI systems used in hiring, lending, healthcare, and housing, while California focuses on transparency and algorithmic bias.  

Because state and federal rules often clash, many companies simply adopt the strictest state standards to ensure nationwide compliance. 

Key regulations to watch: 

  • Executive Order 14365: Pushes toward a unified national AI framework and limits conflicting state AI laws. 
  • Colorado AI Act (SB 24-205): Sets compliance duties for high-risk AI systems starting February 1, 2026. 
  • TAKE IT DOWN Act: Requires removal of non-consensual and harmful AI-generated deepfake content, enforced at the federal level.
