Sigmoid vs Persistent Systems: pros and cons
| Sigmoid | |
|---|---|
| + | Very large pool of cloud-certified engineers (950+) across all three major hyperscalers. |
| + | Data-engineering-first approach reduces the risk of building models on unreliable data pipelines. |
| + | Multi-continent office footprint (US, Europe, South America, India) supports global delivery. |
| + | Twelve-plus years of continuous operation as a bootstrapped, profitable company (per reporting on ~$100M ARR). |
| - | Employee headcount estimates vary meaningfully by source (roughly 600–950), creating some uncertainty. |
| - | Model development itself is positioned as downstream of data engineering, which may not suit buyers wanting a model-first specialist. |
| - | No clearly located aggregate Clutch/G2 star rating in available public sources. |
| - | Pricing and minimum engagement are not published. |
| Persistent Systems | |
|---|---|
| + | Everest Group Leader ranking in the Data & AI PEAK Matrix 2025 (mid-market segment) is an independently sourced third-party validation. |
| + | Purpose-built DxH accelerators for MLOps and bias detection add concrete, named tooling beyond generic claims. |
| + | Publicly traded with 35-year operating history, providing financial transparency. |
| + | Named healthcare client work (e.g., cancer-detection collaboration) with a specific, checkable use case. |
| - | Very large scale (24,000+ employees) means ML/AI is one of several major practice areas competing for delivery focus. |
| - | No clearly located aggregate Clutch/G2 star rating specific to its AI practice in available public sources. |
| - | Pricing model and minimum engagement are not published. |
| - | India-centric delivery model may require additional coordination for clients preferring more localized teams. |
