Viktor Is Now on the Slack Marketplace
Key Takeaways
- Viktor is officially listed on the Slack Marketplace -- reviewed and approved by Salesforce's security team.
- Slack's Marketplace review includes automated security scanning, architecture review, OAuth scope auditing, TLS verification, and manual testing of the full app experience. Out of ~2,900 apps in the directory, fewer than 50 are AI agents.
- The typical review process takes 2-3 months. Viktor was approved in two weeks after its viral launch (2.5 million views on X).
- For enterprise Slack admins (Business+ and Enterprise Grid), Marketplace-listed apps come pre-vetted -- reducing the friction of internal IT approval.
- Viktor is one of only a handful of autonomous AI agents in the Marketplace. Most AI apps in the directory are search tools, summarizers, or IT service desk bots. Viktor is the only general-purpose AI coworker with 3,000+ integrations.
Viktor is now officially listed on the Slack Marketplace. Reviewed by Salesforce. Approved for distribution to Slack's 215,000+ organizations.
This isn't a vanity badge. The Slack Marketplace review is a real security and quality audit run by Salesforce's team. Here's what it actually involves, why it matters, and what it means for your team.
What Slack's Marketplace review actually checks
Slack doesn't just check if your app works. They check if it's safe, well-built, and ready for enterprise deployment. The review covers:
Security:
- Automated web application and network security scanning
- Architecture review of all services that interact with Slack or process user data
- TLS 1.2+ verification on all endpoints
- OAuth scope auditing -- every permission must be justified. Slack rejects apps that request more access than they need.
- Request signing verification (signed secrets or mutual TLS)
- OWASP Top 10 vulnerability assessment
- Slack reserves the right to conduct penetration testing at their discretion
AI-specific requirements (added 2025):
- Full disclosure of LLM models used (Viktor: Anthropic Claude Opus 4.6 and Google Gemini Flash 3.0)
- Data retention, tenancy, and residency details (Viktor: AWS US, encrypted PostgreSQL + Cloudflare R2)
- Explicit policy that the app does not use Slack data to train LLMs
- AI accuracy disclaimers on listing and landing pages
User experience:
- Full end-to-end testing: installation, onboarding, core functionality, and uninstallation
- App must be tested as a new customer would experience it
- Notification hygiene -- no spam, no @channel abuse, batched high-volume messages
- Clear error messages and visual feedback for all actions
- Support response within 2 business days
Ongoing compliance:
- Regular audits after approval
- Resubmission required for any changes to scopes, endpoints, or functionality
- Apps can be delisted if landing pages break, support goes dark, or quality drops
This is the kind of review that typically takes 2-3 months. Viktor was approved in two weeks.
Why two weeks instead of two months
Viktor launched on February 11, 2026 and went viral -- 2.5 million views on X in the first week. The volume of teams trying to install Viktor from Slack accelerated the review timeline. Salesforce's team prioritized the review, and Viktor passed on the first submission.
That's not a shortcut. It's the opposite. When a security review gets fast-tracked, the scrutiny goes up, not down. Viktor was ready because the security architecture was built for this from day one:
- Credential isolation. Viktor never sees your API keys or OAuth tokens. A backend tool gateway injects credentials at execution time. Even if the AI model were compromised, your account credentials are physically inaccessible to it.
- Isolated sandboxes. Each workspace runs in its own execution environment. Your data never touches another company's.
- Approval system. Sensitive actions (sending emails, modifying ad campaigns, deploying code) require explicit human approval via a button in Slack before Viktor executes.
- No Slack data training. Viktor does not use any Slack data to train models. Full stop.
What Marketplace listing means for your team
If you're evaluating Viktor for your company, the Marketplace listing changes three things:
1. IT approval gets easier.
On Slack Business+ and Enterprise Grid plans, admins control which apps can be installed across the organization. Marketplace-listed apps come pre-reviewed by Salesforce -- meaning your IT team doesn't have to run their own security assessment from scratch. The review is already done. The security scanning, the architecture review, the OAuth scope audit -- all completed by Salesforce's team before Viktor was listed.
For teams where app approval is a bottleneck, this removes weeks of back-and-forth with IT.
2. One-click install.
No API keys. No configuration wizards. Find Viktor in the Slack Marketplace, click install, authorize, and Viktor joins your workspace like any other teammate. Connect your tools via OAuth (about 90 seconds per tool), and it's ready to work.
3. Ongoing accountability.
Marketplace apps aren't approved and forgotten. Slack conducts regular compliance audits. If Viktor's landing page breaks, support goes dark, or quality drops, Slack can delist the app. That ongoing oversight means Viktor has to keep meeting the standard -- not just pass once and coast.
How Viktor compares to other AI agents in the Marketplace
Out of ~2,900 apps in the Slack Marketplace, fewer than 50 are AI-powered. And most of those are narrow: search tools, summarizers, or IT service desk bots.
Here's how the AI agents in the Marketplace compare:
| Agent | Marketplace Listed? | What It Does | Integrations | Price |
|---|---|---|---|---|
| Viktor | Yes | Full AI coworker: marketing, ops, finance, engineering, code, deliverables | 3,000+ with read/write | Free tier + paid |
| Slack AI | Native feature | Search and summarize Slack history | Slack only | Included in paid plans (basics in Pro; full AI in Business+ $15/user/mo) |
| Moveworks | Yes | Enterprise IT/HR ticket resolution | Enterprise IT stack | ~$100-200/employee/yr |
| Dust | Yes | AI knowledge assistant over internal docs | Select knowledge sources | From $29/user/mo |
| Glean | Yes | Enterprise search across company knowledge | Enterprise knowledge | ~$50+/user/mo (enterprise) |
| Agentforce | Yes (Salesforce) | Custom AI agents for HR, IT, sales | Salesforce ecosystem | Enterprise pricing |
What stands out: Every other AI agent in the Marketplace is either a search tool (Glean, Dust), an IT service desk bot (Moveworks), or a Salesforce-ecosystem product (Agentforce). Viktor is the only autonomous AI coworker that covers all business functions -- marketing, operations, finance, and engineering -- with 3,000+ integrations and real read/write access.
Lindy, Relevance AI, and Aisera offer Slack integrations but are not listed in the Marketplace -- meaning they haven't gone through Salesforce's review process.
What Viktor actually does (for teams discovering it through the Marketplace)
If you're finding Viktor for the first time through the Slack Marketplace, here's the 60-second version:
Viktor is an AI coworker that lives in Slack. You @mention it like a teammate. It connects to 3,000+ business tools -- Stripe, HubSpot, Meta Ads, Google Ads, Notion, Linear, GitHub, PostHog, and more -- and does real work:
- Marketing: Pulls ad performance from Meta Ads and Google Ads, compares periods, delivers PDF reports with charts
- Operations: Matches invoices to bank statements, generates reconciliation spreadsheets, flags discrepancies
- Engineering: Clones repos, creates branches, fixes bugs, submits pull requests
- Finance: Analyzes Stripe revenue, models pricing scenarios in Excel, delivers board-ready summaries
- Internal tools: Builds and deploys full-stack web apps (Viktor Spaces) from a single Slack message
- Proactive automation: Notices patterns in your team's work and suggests automations before you ask
- Scheduled tasks: Daily digests, weekly audits, monthly reports. Set once, runs forever.
Each Viktor instance runs on its own persistent cloud computer with a full Linux sandbox. It has persistent memory that learns your company over time. And every sensitive action requires your explicit approval before executing.
"Slack was built to be the place where work happens. We're building Viktor to be the coworker that does the work. Getting approved for the Marketplace means every team on Slack can now add Viktor with one click and see what that looks like." -- Fryderyk Ovcaricek, CEO, Zeta Labs
