We're on a mission to eliminate the friction that slows down software teams worldwide
In 2024, our founders—former engineering leaders from Google, Meta, and startups—noticed a recurring pattern: brilliant product ideas were getting bottlenecked at the planning stage.
Product managers would spend weeks crafting beautiful PRDs, only to watch them sit in limbo while engineering teams scrambled to translate vague requirements into technical specs, architecture diagrams, and actionable tasks. The process was manual, inconsistent, and painfully slow.
We asked ourselves: "What if AI could do in minutes what takes engineering teams days?"
That question led to SpecToStack. We combined our expertise in software architecture, AI/ML, and engineering management to create an intelligent assistant that truly understands the engineering planning process—from clarifying ambiguous requirements to generating production-ready technical designs.
Today, we're helping 500+ engineering teams ship faster by eliminating the planning bottleneck. And we're just getting started.
To empower engineering teams to move from idea to execution 10x faster by automating the tedious, error-prone parts of technical planning—while preserving the creative, strategic thinking that humans do best.
A world where every software team—from startups to Fortune 500s—has access to AI-powered planning tools that make engineering as efficient and predictable as manufacturing.
The principles that guide everything we build
We believe you shouldn't have to choose between moving fast and building right. Our AI accelerates planning without compromising quality.
Generic AI tools give generic results. We've trained our models specifically on software engineering patterns and best practices.
Your ideas and architectures are your competitive advantage. We never train our models on customer data without explicit consent.
Great planning tools shouldn't be a privilege. We offer generous discounts to nonprofits, education, and early-stage startups.
AI should augment, not replace, human judgment. Our tools provide smart suggestions while keeping humans in control.
We ship new features every week based on customer feedback. Your voice directly shapes our product roadmap.
