Profound and Arenza are both Generative Engine Optimization (GEO) platforms, but they target different buyers and make different architectural bets. This comparison is dated May 2026 and uses publicly available information from each vendor's website + product documentation. We update it monthly; if a fact is wrong, email hello@arenza.ai and we'll correct it.
TL;DR — who wins what
| Dimension | Winner | Why |
|---|---|---|
| Enterprise SLA + dedicated CSM | Profound | Profound is built for Fortune-1000 brand teams; has had 18 months to build a managed-service motion. |
| Agency multi-brand workflow | Arenza | Built agency-first: bulk import, copy-settings A→B, white-label from Protect tier, per-brand Slack channels. |
| Number of AI platforms covered | Arenza | 10 on Protect (ChatGPT, Gemini, Perplexity) vs Profound's 4-5 (ChatGPT, Gemini, Perplexity primary; others vary). |
| Wrong-claim / hallucination tracking | Arenza | Accuracy is a first-class pillar with severity scoring + verbatim quote storage + auto-deployed fixes (llms.txt + schema). Profound focuses on mention frequency. |
| Sample size + statistical rigor | Profound | Larger sample volume (50M+ mentions claimed); longer history. |
| MCP-native integration | Arenza | mcp.arenza.ai exposes 10 tools to AI agents (Claude Desktop, Cursor, etc.) directly. Profound is dashboard-first. |
| Public REST API + open-source SDKs | Arenza | TypeScript + Python SDK + LangChain / LlamaIndex / Vercel AI SDK + n8n / Cursor / Slack / Zapier integrations all public on GitHub. |
| Bilingual / multilingual UI | Arenza | Bilingual zh-CN + en-US shipping; ar/es/ja/de/pt roadmap committed Q3 2026. Profound is English-only. |
| Headline price | Arenza | Pro at $9.99/mo (single brand, ChatGPT) is ~98% under Profound's $499 floor. Protect at $99/mo + usage (multi-brand, all 10 LLMs, white-label) is ~80% under. |
Pricing
Public pricing as of May 2026, USD per month:
| Tier | Profound | Arenza |
|---|---|---|
| Free / trial | No persistent free tier; demo by request | Free — 1 manual scan/week, ChatGPT only, 10 prompts hard cap, 1 brand |
| Entry | Starts at $499/mo (per public site) | $9.99/mo Pro — single brand, ChatGPT only, 50 prompts (extras at $0.25/prompt-month), accuracy + fix suggestions, Slack + Lark, weekly auto-scan |
| Mid (multi-brand) | Custom — typical agency rate cards land at $300+/brand | $99/mo + usage Protect — multi-brand workspace, all 3 AI platforms, white-label, REST API + MCP server, daily auto-scan, auto-deployed fixes. Base includes 1,000 scans + 10 findings + 5 fixes/mo; overage $0.05/scan + $1/finding + $5/fix. |
| Enterprise | Custom, with dedicated CSM + SLA | $999/mo + usage Enterprise — 50,000 scans + 500 findings + 100 fixes/mo (40-50% off Protect unit overage at $0.03/scan + $0.50/finding + $3/fix), real-time scanning, SSO, SOC 2, 99.9% SLA, dedicated CSM, multi-region |
For an agency managing 20 client brands, the public pricing math: Profound at $300/brand is $6,000/mo. Arenza Protect at $99/mo + usage (one workspace, all 20 brands) — even with 3,000 scans + 20 findings + 10 fixes a month layered on top of base, the all-in lands around $234.00/mo. That's roughly 96% under Profound — the agency-vs-enterprise positioning gap, not a quality gap.
AI platform coverage
- Profound (May 2026): primary coverage of ChatGPT, Gemini, Perplexity. Coverage of Claude, Copilot, Grok depends on tier and roadmap announcements.
- Arenza: full coverage of all 3 AI platforms (ChatGPT, Gemini, Perplexity) included from the Protect tier ($99/mo + usage). The Pro tier ($9.99/mo) is intentionally ChatGPT only — the budget option for solo brand owners who only need to track the dominant LLM.
If you only care about ChatGPT and Gemini, Profound's deeper sample size in those two LLMs may matter more than Arenza's wider coverage. If you're tracking a category where Claude, Perplexity, or Google AI Overviews drives meaningful share, Arenza Protect's all-10 coverage is the only complete picture.
Accuracy / hallucination tracking — the biggest functional gap
Profound's product description emphasizes "Brand Visibility Index" — the share-of-voice metric. Arenza's accuracy pillar (wrong-claim detection with severity scoring + verbatim quote storage, with auto-deployed fixes on Protect tier) is a distinct function not present at the same depth in Profound's public surface.
For a regulated brand (financial services, healthcare, legal), the wrong-claim detection isn't a nice-to-have — it's the entire point of running a GEO tool. A 30%-share-of-voice number is meaningless if the AI is repeatedly stating an incorrect maximum loan amount or an outdated drug indication.
Agency features specifically
- White-label reports: Arenza includes white-label from the Protect tier ($99/mo + usage). Pro doesn't include it (single-brand by design). Profound gates white-label to Enterprise.
- Bulk CSV import: Arenza ships CSV bulk-add (50 brands in one paste). Profound is one-brand-at-a-time per public docs.
- Copy-settings A→B: Arenza lets you copy a brand's competitor list + tracked prompts to another brand in one click.
- Per-brand notifications: Arenza ships per-brand Slack / Lark / webhook routing. Profound: workspace-level notifications.
Integrations (publicly documented as of May 2026)

| MCP server | Not published | Yes — mcp.arenza.ai with 10 tools, OAuth + Bearer auth |
| LangChain / LlamaIndex / Vercel AI SDK | No | Open-source on GitHub (arenza-langchain, arenza-llamaindex, arenza-vercel-ai-sdk) |
| n8n / Zapier templates | No public templates | Public templates + manifest at github.com/arenza-ai/arenza-n8n-template + arenza-zapier-actions |

Who picks Profound
- Single Fortune-1000 brand with a centralized brand-marketing team.
- Need for a managed-service relationship + dedicated CSM as part of the contract.
- Workflow lives entirely inside the Profound dashboard — no need for code-side integration.
- Coverage of ChatGPT + Gemini is sufficient for the category being tracked.
Who picks Arenza
- Agency managing 10-200 client brands and needing white-label + bulk operations from day 1.
- Multi-LLM coverage matters — especially Claude (high in legal / SaaS) or Perplexity (high in research / B2B).
- Wrong-claim tracking is a hard requirement (regulated industries, brand-safety-sensitive categories).
- Engineering or DevRel team owns the GEO motion and wants programmatic + MCP-native integration.
- zh-CN UI requirement (Chinese market or bilingual agency).

Methodology note
Comparison data was collected from each vendor's publicly accessible website on 2026-05-05. Where a feature's existence depends on a private SLA tier or sales-call disclosure, it is annotated. We do not have access to non-public Profound pricing; the agency rate-card estimate ($300+/brand) comes from third-party agency procurement reports and may not reflect current sales practice.
If you work at Profound and find a factual inaccuracy here, email hello@arenza.ai with a public-source citation and we will update within 48 hours. We track this as a wrong-claim finding against Arenza's own brand and resolve it the same way we ask customers to resolve theirs.
