Where Nagent fits
the multiplayer AI platform for growth teams
Multiplayer AI platform for growth teams: AI agent teams for marketing, sales and CX work with people in one shared workspace, with Smriti memory, Karma scoring and autonomy that is earned, not deployed. Solo $29.99 per month ($19.99 on annual billing), Team $299 ($199), Business $1,499 ($999), Enterprise by quote. Credits per month are the unit of agent work; Growth Pods add human experts on Business and Enterprise.
Horizontal platforms compete on how people connect company knowledge, delegate work and keep control across tools. The central question is whether a reusable workspace can become an operating process, with a named owner and a reliable path from request to approved action. A visually appealing agent builder is only one part of that decision.
How to evaluate this category
Three evaluation scenarios for this category. Each names the inputs, the required output and the measure.
Account research to approved follow-up
Give the team an account record, a current product brief and a small set of approved customer references. Ask it to identify a relevant problem, distinguish observed facts from inferred needs, and prepare a follow-up for review. Then change one source and require a second person to correct the draft without restarting the research.
Measure: source accuracy, reviewer minutes, approved follow-ups and CRM consistency.
Campaign brief to coordinated delivery
Start with one campaign objective, audience, budget constraint and brand guide. Require research, a brief, assets and a release checklist with distinct human owners. Introduce an unresolved claim midway through the process. The system should retain useful work while preventing that claim from silently propagating into every asset.
Measure: accepted assets, revision burden, approval latency and missing handoffs.
Customer insight to shared learning
Provide anonymized support themes and sales objections. Ask for a synthesized insight, a proposed campaign adjustment and a knowledge update. A marketing owner and a CX owner should review the same underlying evidence. The exercise tests cross-functional context and accountability, not merely summarization quality.
Measure: evidence coverage, disagreement resolution and reuse of approved learning.
The evaluation owner should be a growth operations lead. Use accepted work completed across tools as the business target.
