If you’re a non-technical founder, chances are you’ve been burned by flaky devs, vague timelines, or code that doesn’t match the prototypes. That’s exactly why we built a model designed for trust.

At Designli, we pair non-technical software founders with full-time, founder-aligned product teams. Software engineers, designers and product owners who don’t just speak code, they speak human. We guide you through every step with clarity, structure, and care.

How it works, and what we can build:

Starting from Scratch?

We turn your idea into a clickable, interactive prototype with a feature roadmap and estimates so you can align co-founders, test the market, or pitch investors before writing a single line of code. No dev required (yet).

Recovering from a Bad Build?

Our team audits your codebase, cleans up what’s broken, and builds a plan for a second launch you can trust. We don't start over, we step in and make it better, fast.

Scaling What You’ve Built?

We help you scale with purpose. That means feature roadmaps tied to real metrics and user insights, not gut instinct or guesswork.

Each path begins with a dedicated product team assigned full-time to your project. Whether you need a prototype, a clean codebase, or a smarter scaling strategy, we’ll guide you there with clarity, speed, and craftsmanship you’ll be proud of.
