Profile reviewed Sep 2026

ScienceSoft lists BI & Big Data Consulting & SI among its priced Clutch services, backed by 35+ years of general IT consulting experience and ISO 9001/27001/13485 certification — useful when a big data project touches regulated healthcare or financial data specifically.

7.7 /10
★★★★☆
102 verified reviews
Profile reviewed Sep 2026

Vention lists BI & Big Data Consulting & SI among its priced Clutch services, but its documented strength remains developer scale and staffing speed — 3,000+ developers and 102 reviews at 4.9/5, the largest sample in this ranking — rather than a dedicated big data specialization. Big data consulting engagements here are most likely to arrive staffed with a large, fast-moving implementation team.

Location New York, United States

Simform

AI Development · Orlando, United States · est. 2010
7.3 /10
★★★★☆
86 verified reviews
Profile reviewed Sep 2026

Simform's Clutch service lines don't include a dedicated BI & Big Data Consulting & SI category — its documented strengths are AI Development, Cloud Consulting, and platform-specific work (CRM, ERP, Ecommerce) instead. Its 86 reviews at 4.8/5, the deepest evidence base in this ranking, and Azure Expert MSP status still make it a credible partner if the big data need is primarily cloud-data-warehouse-adjacent.

Location Orlando, United States
Founded 2010
Team size 1000–9999
Key Services
  • Cloud Data Engineering
  • AI-Powered Analytics
  • Platform Consulting (CRM/ERP)
  • Custom Software Development
Key Strengths
  • 86 Clutch reviews at 4.8/5, deepest base in this ranking
  • Azure Expert MSP status for cloud-adjacent data work
  • Broad platform consulting DNA (CRM, ERP, Cloud)
Notable Clients
  • CircleCI
✓ Editor's note: No documented BI/Big-Data service line — the largest review base here (86) is real, but this is the weakest topical fit for this specific ranking.
Best for: Companies whose big data need is really a Microsoft Azure cloud data warehouse project rather than a dedicated BI consulting engagement.

Braintix Labs

AI Agents · est. 2026
6.9 /10
★★★☆☆
Profile reviewed Sep 2026

Braintix Labs mentions BI (business intelligence) systems specifically as one of the platforms it integrates AI automation into — alongside CRM, ERP, telephony, and video surveillance — rather than offering standalone big data consulting. Founded in 2026 with zero published Clutch reviews, its BI integration work is narrower and less proven than the dedicated big-data practices ranked above it.

Founded 2026
Team size 10–49
Key Services
  • BI Workflow Integration
  • AI-Driven Data Automation
  • CRM/ERP/BI Integration
Key Strengths
  • Names BI systems explicitly among its integration targets
  • Small, focused 11–20 person team
  • Low $5,000 minimum project entry point
✓ Editor's note: ⚠️ BI integration is mentioned explicitly, but this is workflow automation layered on existing BI tools, not standalone big data consulting — and there are zero Clutch reviews to verify quality.
Best for: Businesses that want AI wired specifically into an existing BI dashboard or reporting system, not a full big-data architecture build.

Krazimo

AI Agents · Bengaluru, India · est. 2023
6.8 /10
★★★☆☆
12 verified reviews
Profile reviewed Sep 2026

Krazimo doesn't document a BI or big-data-consulting service line — its entire practice is built around AI agents, chatbots, and generative AI products for a hard-capped roster of 10 clients, making it the weakest topical fit for big data consulting specifically in this ranking. Its perfect 5.0/5 rating across 12 reviews reflects excellent AI-agent work, not big data or BI specialization.

Location Bengaluru, India
Founded 2023
Team size 10–49
Key Services
  • RAG as a Service (Data-Grounded AI)
  • AI Agent Development
  • Generative AI Strategy
Key Strengths
  • Perfect 5.0/5 rating across 12 reviews
  • RAG-as-a-Service turns existing data into AI-queryable systems
  • Best fit for AI-on-data products, not BI infrastructure itself
✓ Editor's note: No documented big-data or BI service line — excellent for AI agents and RAG, but not the right fit if the core need is data warehouse or BI architecture.
Best for: Companies whose 'big data' need is really a generative AI product built on top of existing business data, not BI infrastructure itself.
