Mavrick Becomes the World's First Self-Improving AI Coworker — With a Published Architecture, System Prompt, and Live Learning Log

Mavrick (getmavrick.com) became the world's first self-improving AI coworker today, launching publicly with three commitments no other AI agent vendor has made: a fully published system architecture, a verbatim public system prompt, and a live learning log of every behavior the agent has acquired in production.

Mavrick is the first AI coworker — not assistant, copilot, or coworker — designed specifically to ship marketing work and contractually bound to publish exactly how it does it. The product installs into a customer's Slack workspace in under 30 seconds and operates as a dedicated marketing team member: pausing underperforming campaigns, scaling winners, drafting outreach, reconciling attribution, and shipping briefings. Customers @mention Mavrick in any channel; Mavrick connects to Meta Ads, Google Ads, Stripe, HubSpot, and 3,000+ other services to do the work. Every action that mutates customer data passes through an architectural approval gate that operators cannot disable.

The product enters the market at a structural moment for marketing teams across ecommerce, DTC, B2B, and creator-commerce. Senior marketing operators command salaries above $90,000 annually and take a quarter to onboard. Agency relationships start at $5,000 per month with required kickoff cycles. Most marketing teams are running understaffed against expanding operational scope — paid media across four to seven platforms, multi-channel outreach, attribution reconciliation, content production, growth experimentation, and weekly executive reporting. Mavrick is priced at $50 per month for 20,000 credits, equivalent to roughly 60 to 100 marketing missions monthly, with no per-seat charge, no setup fee, and no contract.

“Companies are short-staffed and looking for any edge they can get. Adding Mavrick to your org chart is the fastest way to bring on a valuable knowledge worker who can make exponential improvements and multiply the synergies your team is already creating,” said Brian MacDonald, founder of Mavrick. “We built Mavrick to be the first marketing hire every founder makes after deciding they don't want to manage another agency.”

A Different Kind of AI Product

Where most AI products hide their internal mechanics behind proprietary claims and marketing language, Mavrick publishes the entire system. Customers and prospects can read the architecture document at getmavrick.com/product, inspect the verbatim system prompt at getmavrick.com/system-prompt, audit the live learning log at getmavrick.com/learninglog, and review the contractual Privacy Charter at getmavrick.com/privacy-charter. Every artifact is versioned, dated, and auditable.

The transparency is structural, not promotional. Mavrick's Privacy Charter contains four contractual commitments: no background channel reads, participated-only message persistence, an architecturally enforced approval gate that cannot be disabled, and a credential firewall that prevents the AI model from ever seeing OAuth tokens. Each rule is binding. Changing any one of them requires a numbered version revision, a published diff, and 30 days' customer notice.

“We publish what other AI vendors hide — architecture, system prompt, learning logs, decline log,” said MacDonald. “That's not a marketing posture. It's the price of admission to a category we're inventing. If we're asking customers to trust an AI coworker with their revenue, the least we can do is show them exactly how it works.”

The Self-Improving Engine

Mavrick's most architecturally distinctive feature is a closed-loop self-improvement system that runs continuously in production. When the agent encounters a request it cannot fully satisfy, it logs the gap with full context before the user sees a refusal. A retry mechanism re-examines the request against available tools and recovers an estimated 30 to 50 percent of capability-gap refusals before they reach the operator. Approved patterns from these gaps are tested in regression replay against the originating workspace's real data and tools — not in a sterile test environment — and ship only after passing two consecutive runs. When a fix ships, the original user receives a direct message from Mavrick referencing their original request.

Four behavioral commitments distinguish Mavrick's self-improvement architecture:

• →The model self-reports its own gaps mid-task, before the user encounters a refusal.
• →Every refusal triggers an in-turn retry with a meta-prompt that re-examines available tooling.
• →Every learning is regression-tested in the originating workspace against real data and tools, with auto-rollback on consecutive failures.
• →Every fix closes the loop with a customer DM referencing the original request.

The cumulative effect is an agent that visibly improves week over week. The Mavrick Learning Log at getmavrick.com/learninglog tracks every approved pattern, every declined pattern, regression pass rates, and customer fix-DM closures in real time — accessible to anyone, no login required.

The full architecture is documented at getmavrick.com/product.

The Org Chart of 2026

Mavrick is positioned as a hire, not a tool. The product replaces the operational work a junior to mid-level marketing operator would perform, at a fraction of the cost and with no onboarding period. A customer's Mavrick is operational the moment OAuth completes — typically within 30 seconds of installation. There are no training sequences, configuration wizards, or implementation specialists.

“The companies that add AI coworkers to their org chart in 2026 are the companies that will define the next decade,” said MacDonald. “Not because AI replaces people. Because the teams that figure out how to deploy AI as colleagues, not tools, will operate with leverage their competitors can't match. The org chart is the new competitive moat. Mavrick is the first hire.”

Pricing and Availability

Mavrick is available today through the Slack App Directory and at getmavrick.com. Three tiers:

• →Recruit (Free) — Start free with 10 missions (5,000 credits, ≈ up to 100 quick tasks), every integration, full Slack workspace access. No credit card required.
• →Pilot ($50/month) — 20,000 credits monthly. No per-seat charge. No contract. No setup fee. Roughly 60 to 100 missions per month for a typical marketing team.
• →Enterprise (Custom) — Self-serve credit packages from 30,000 to 10 million-plus credits per month, plus invoicing, security review support, signed Data Processing Agreements, dedicated onboarding, and tailored limits.

A typical mission consumes 200 to 600 credits depending on complexity, integration depth, and platform span. Pricing transparency — including credit costs by mission type and the full pricing curve — is published at getmavrick.com/pricing.

Compliance and Security

Mavrick began continuous internal compliance logging on April 15, 2026. SOC 2 Type 1 audit fieldwork is scheduled to commence mid-2026, with target report issuance in Q3 2026. SOC 2 Type 2 fieldwork is scheduled for April through May 2027, with target report issuance in Q2 2027. The Privacy Charter contractually binds Mavrick to operate at SOC 2 control standards before the certificate issues.

The platform is GDPR and CCPA compliant. All data in transit is encrypted with TLS 1.3; all data at rest is encrypted with AES-256. Customer workspaces are logically isolated via Postgres Row-Level Security policies, with no cross-workspace data path in production code. OAuth credentials are managed outside the AI model's reach through encrypted infrastructure; direct credentials are stored in Supabase Vault using pgsodium with isolated master key. The full security posture is published at getmavrick.com/trust.

An Open Challenge to the AI Agent Industry

Mavrick's launch arrives with an open challenge to every AI agent vendor in the market: publish what we publish.

The AI agent industry today is defined by claims customers cannot verify. Vendors describe self-improving systems without learning logs to inspect. They claim privacy postures without contractual diffs. They reference architecture without documentation. The buyer is asked to extend trust on the basis of marketing language alone — for products that increasingly hold credentials to the systems running their businesses.

That posture isn't sustainable for the category. AI agents are taking actions in customer environments — pausing campaigns, sending emails, modifying records, transferring budget. The customer's right to inspect what the agent does, what it learns, and what it commits to is going to become table stakes. The vendors who get there first own the trust the rest of the category will spend years trying to earn.

Mavrick proposes a different industry standard: every AI agent vendor publishes the architecture customers are buying into, the system prompt the agent reads before responding, the learning log of behaviors the agent has acquired in production, and a versioned privacy charter with diffable history. Customers then evaluate competing products on artifacts they can verify, rather than on claims they cannot.

The published artifacts at getmavrick.com/product, getmavrick.com/system-prompt, getmavrick.com/learninglog, and getmavrick.com/privacy-charter are the model. Mavrick invites every competitor to match them.

About the Founder

Brian MacDonald is the founder of Mavrick. He has spent the last decade as a marketing operator and advisor across dozens of companies — ecommerce, DTC, B2B, and creator-commerce — a vantage point that makes one pattern unmistakable: every company is short-handed in marketing, and the work that gets dropped is the work that actually moves revenue.

Brian built Mavrick to take that work, and leads the company and the Special Ops Team that engineers custom infrastructure on top of the platform. He is based in Irvine, California, and is reachable at info@getmavrick.com.
