Build your stack
the right way.
A simple, opinionated project operating system for modern builders, agencies, and AI-native teams.
No bloat. No busywork. Just the tools you actually need to ship.
The Problem
The problem isn't work. It's everything around the work.
- 01
Too many dashboards. You're jumping between 5 tools just to track what's happening.
- 02
Too many statuses. Backlog, Groomed, Sprint-Ready, In Progress, In Review, QA, Staging, Done. Really?
- 03
Too many notifications. Every tool pinging you, none of it actionable.
- 04
Too much process. Standups, retros, planning poker. Rituals that outlived their usefulness.
AI has made execution faster, but overhead stayed the same. Buildstack exists to fix that.
What Is Buildstack?
The engine behind Mayven. Refined over years of real client work.
One place that doesn't fight how you work.
Task Execution
Clear boards. Clear ownership. No ceremony.
Conversations
Threaded discussions tied to work, not lost in Slack.
Visibility
Real-time dashboards. Always know what's shipping.
Accountability
Know who owns what. No ambiguity.
Built by Mayven
The system that powers Mayven.
Mayven is our software development agency. A team of AI-native engineers who build production systems for startups and product teams.
Over years of real client work, we built Buildstack to run our projects: tasks, discussions, visibility, invoicing, and outcomes. Without the bloat of traditional tools.
Now, we're opening it up.
Buildstack is the engine.
Mayven is what it looks like when the engine is used well.
Core Features
Everything you need. Nothing you don't.
Kanban Task Boards
Drag-and-drop boards that keep work visible and moving. No 15-status workflows. Just what matters.
Threads for Real Discussions
Conversations that live next to the work, not buried in a chat app. Context stays attached.
Unified Inbox
One inbox for tasks, mentions, and updates. No more checking five places for what needs your attention.
Clear KPIs & Dashboards
Real-time visibility into what's shipping, who's delivering, and where things stand. No guesswork.
Optional Invoicing
Stripe Connect-powered invoicing built in. Bill clients without leaving your project OS. Use it or don't.
Built for the AI Era
AI-native by design. Not a marketing gimmick.
AI is used only where it meaningfully reduces friction. No generic copilots. No constant message rewriting. No AI-generated noise.
AI assists. Humans decide.
Inbox-Native Daily Standups
Automatically generated standups delivered to each user's inbox. What moved forward, what's in progress, what's blocked, what's at risk. No meetings required.
- Founders and leads get instant visibility
- Teams stay aligned without check-ins
- Works across multiple projects
Task & Thread Summaries
AI-generated summaries for tasks, threads, and project-level activity. Key decisions, open questions, current status, and next actions. Surfaced in seconds.
- Faster onboarding to any task or thread
- Less rereading, better context preservation
- Always up to date
Thread → Product Spec
Convert discussion threads into structured specs: problem statement, goals, requirements, constraints, and open questions. Designed to be copy-pasteable into AI coding tools.
- Cleaner handoffs, faster execution
- Works with Claude Code, Cursor, etc.
- Human-reviewable and editable
Task State Intelligence
AI observes task behavior and flags what matters: likely blocked, stale, high-risk, or moving faster than expected. Based on thread activity, task movement, and dependency patterns.
- Earlier intervention on problems
- Less micromanagement needed
- Better prioritization signals
Weekly Outcome Summaries
Weekly reports focused on outcomes, not activity. Features shipped, systems unblocked, risks reduced, decisions finalized. No vanity metrics or raw task counts.
- Clear business signal for stakeholders
- Aligns teams around impact
- Replaces manual status updates
Lightweight Time Tracking
Built-in time tracking designed for internal clarity, not client billing. See where your team's attention goes, spot opportunities to automate or delegate, and make better planning decisions. Never a surveillance tool.
- Track time per task without leaving Buildstack
- Understand effort patterns to improve estimates
- Designed for leverage, not micromanagement
Less reporting. More building.
If it doesn't reduce friction, it doesn't ship.

Our Story
Why we're building this (again).
Seven years ago, we built the first version of Buildstack internally at Mayven. It was the system that powered every client project — task boards, threads, dashboards, invoicing. It worked. But the market wasn't ready for another project management tool.
Today, it is.
The rise of AI-native teams has changed what people need. Not more features — more focus. Not more integrations — more opinions. Teams are smaller, faster, and allergic to bloat. They need a tool that matches that energy.
Buildstack isn't trying to be everything. It's trying to be right.
Build your stack — the right way.
