Gartner’s Global Business Sales (GBS) segment was primarily established following the $3.3 billion acquisition of CEB (Corporate Executive Board) in April 2017. While GBS initially saw a decline in revenue as Gartner divested non-core CEB assets (such as Talent Assessment), the segment has since transitioned into a high-growth, high-margin subscription engine.
The following data tracks GBS Research Revenue (the core subscription business) rather than total company revenue, as this is the metric Gartner uses to measure segment health.
GBS Revenue Growth (2017–2025)
| Year | GBS Research Revenue ($M) | YoY Growth (%) | Context / Key Drivers |
|---|---|---|---|
| 2017 | ~$775 | — | Pro-forma annualized (CEB integrated April 2017). |
| 2018 | $771 | -0.5% | First full year; heavy focus on CEB integration. |
| 2019 | $716 | -7.1% | Divestiture of non-core CEB business lines. |
| 2020 | $692 | -3.4% | Impact of the COVID-19 pandemic on new sales. |
| 2021 | $775 | +12.0% | Post-pandemic rebound; record retention rates. |
| 2022 | $881 | +13.7% | Expansion into HR, Supply Chain, and Finance. |
| 2023 | $994 | +12.8% | Double-digit growth in Contract Value (CV). |
| 2024 | $1,113 | +12.0% | Reached $1.2B in total Contract Value. |
| 2025 | $1,148 | +3.1% | Slowdown due to U.S. Federal budget headwinds. |
CAGR Analysis
To calculate the Compound Annual Growth Rate (CAGR), we look at the period from the first full year of integration (2018) to the most recent full-fiscal year (2025).
- Beginning Value (2018): $771 Million
- Ending Value (2025): $1,148 Million
- Time Period: 7 Years
CAGR=(7711,148)71−1≈5.85%
[!NOTE] While the Revenue CAGR is ~5.9%, the Contract Value (CV) CAGR—Gartner’s preferred forward-looking metric—is significantly higher, averaging ~11-13% over the last four years. This discrepancy exists because revenue lags CV due to the subscription-based recognition model.
Segment Health & Strategic Outlook (2026)
- High Margins: The GBS sales channel operates within the "Insights" segment, which maintains a contribution margin of ~78%.
- Focus Areas: GBS now covers all enterprise functions beyond IT, specifically targeting HR, Finance, Supply Chain, Sales, Marketing, and Legal.
- Recent Headwinds: Growth in late 2025 and early 2026 slowed to ~3% primarily due to the "Federal drag"—a slowdown in U.S. government contract renewals—which management expects to lap by mid-2026.
- 2026 Divestiture: In early 2026, Gartner sold its Digital Markets business (Capterra, Software Advice) to G2. While these assets were related to business sales, their removal will streamline the GBS segment back to its pure-play research roots.
