Aquarium hobbyists are obsessive about water parameters, stocking levels, and compatibility — and they're currently tracking it all in spreadsheets, Reddit posts, and memory. TankMate lets you build a virtual version of your tank, log water tests over time with trend charts, get compatibility warnings when you add new fish, and track your maintenance schedule. It's Strava but for fishkeeping nerds.

An AI-native X Articles publishing platform that helps creators and founders produce long-form content optimized for X's algorithm. You input a topic or thread and it generates a full Article draft with proper formatting and embedded media suggestions and internal linking and SEO-optimized structure. It tracks performance analytics (views and read-through rate and engagement) across all your Articles and A/B tests headlines. Built for the new reality that X Articles are now the largest blogging platform by traffic.

A monitoring and observability platform for autonomous AI agent deployments. You install a lightweight SDK and it tracks every agent run — tokens consumed and tools called and errors hit and costs incurred and time spent and outcomes achieved. Get real-time dashboards showing agent health and cost anomalies and failure patterns and ROI per workflow. Set alerts for runaway costs and stuck loops and degraded performance. Think Datadog but for AI agents.

AI-native bookkeeping built specifically for freelancers and solopreneurs. You connect your bank account and the AI automatically categorizes transactions and tracks project-based profitability and estimates quarterly taxes in real time and handles multi-currency conversions and generates Schedule C-ready reports. Talk to your books naturally — ask 'How much did I spend on software this quarter?' or 'Am I on track for estimated taxes?' and get instant answers.

An AI-native subscription recovery and dunning management tool. You connect your Stripe account and it automatically detects failed payments sends personalized recovery sequences (email and SMS and in-app) updates payment methods via smart retry logic and recovers revenue you'd otherwise lose. The AI personalizes timing and messaging based on customer behavior patterns and optimizes retry schedules for each payment processor.

A multi-model agent orchestrator that automatically routes each subtask to the optimal LLM based on task type and cost and latency requirements. You define your workflow and ModelRouter picks Claude for reasoning-heavy steps and GPT for certain code generation and Gemini for long-context analysis and local models for simple classification — all transparently. You get a unified API with automatic fallback and cost tracking per model and performance comparisons.
