8.3 /10
★★★★☆
31 verified reviews
Profile reviewed Sep 2026

ELEKS documents Chatbots & Conversational AI at 10% of its AI Expertise mix — a real but secondary capability behind Machine Learning (42%) and Natural Language Processing (26%) — reflecting its position as a broad enterprise engineering house rather than a chatbot specialist. Its 4.8/5 rating across 31 reviews and 2,000+ employee bench support chatbot builds that need to plug into much larger enterprise systems.

ScienceSoft

AI Agents · McKinney, United States · est. 1989
7.8 /10
★★★★☆
42 verified reviews
Profile reviewed Sep 2026

ScienceSoft doesn't publish a chatbot-specific service breakdown — its AI work is folded into a much broader IT consulting practice spanning healthcare, fintech, and cybersecurity. Its 4.8/5 rating across 42 reviews and ISO 9001/27001/13485 certifications make it a credible generalist option, but the least chatbot-specific evidence in this particular ranking.

  • Healthcare & FinTech AI
  • Cybersecurity

Intellias

AI Consulting · Kraków, Poland · est. 2002
7.4 /10
★★★★☆
30 verified reviews
Profile reviewed Sep 2026

Intellias doesn't document a specific Chatbots & Conversational AI percentage in its published AI Expertise breakdown — its strongest documented AI signal is Generative AI at 15% and AI Consulting at 10%, more oriented toward broader GenAI products than narrow chatbot builds. Its 4.9/5 rating across 30 reviews, the second-highest in this ranking overall, still makes it a credible choice for a chatbot delivered as part of a larger generative AI initiative.

Location Kraków, Poland
Founded 2002
Team size 1000–9999
Key Services
  • Generative AI Product Development
  • AI Consulting
  • Conversational Features (within larger builds)

Braintix Labs

AI Agents · est. 2026
7.2 /10
★★★★☆
Profile reviewed Sep 2026

Braintix Labs isn't positioned as a chatbot specialist specifically — its stated focus is turning calls, documents, footage, and business data into automation wired into existing CRM, ERP, BI, and telephony systems, which touches conversational AI through call handling without naming 'chatbot' as a distinct offering. Founded in 2026 with zero published Clutch reviews, its conversational-AI capability is unverified and should be confirmed directly before engaging.

Founded 2026
Team size 10–49
Key Services
  • Call & Voice Automation
  • AI-Driven Document Processing
  • Telephony Integration
Key Strengths
  • Call automation wired into existing telephony stacks
  • Small, focused 11–20 person team
  • Low $5,000 minimum project entry point
✓ Editor's note: ⚠️ No named chatbot service line and zero verified Clutch reviews — its 'calls' automation may be conversational-AI adjacent, but confirm scope directly.
Best for: Businesses that need voice or call automation integrated into an existing telephony stack, rather than a standalone web chatbot.
