Launching a startup saas mvp in 90 days

overview

Example Engagement
Industry: Startup SaaS (Illustrative)
Scope: From idea validation to investor ready MVP launch
Timeline: 90 days
Objective: Show how a typical founder engagement with Harnik Digital unfolds

Note: This case study is illustrative, based on common founder challenges. It is designed to demonstrate Harnik Digital’s approach and the results early stage startups can expect.

The challenge

Early stage founders often face the same dilemma:

  • They have an investor pitch or early customers waiting

  • They need a working product fast, not just wireframes or slides

  • Hiring a full in house team is expensive and time consuming

  • Offshore freelancers can’t be trusted with quality or to deliver on time

In this example scenario, a SaaS founder needed to have a working MVP ready in just 90 days to secure their next funding round. The product scope included:

  • A responsive web app with authentication and onboarding

  • A core feature set that demonstrated the unique value of the idea

  • An admin panel to manage users and monitor activity

  • A product polished enough to demo to investors and test with pilot customers

The challenge: move from idea to live product in three months, without sacrificing quality or overspending.

The solution

Harnik Digital applies a repeatable, structured process to turn raw ideas into investor ready SaaS MVPs. This engagement followed a clear three phase roadmap:

  1. Discovery (Weeks 1–2)

    • Collaborated with the founder to define scope and prioritize features

    • Received mockups and made minor improvements to focus on the core value proposition

    • Chose a scalable tech stack (React + Node.js, with cloud hosting)

  2. Build (Weeks 3–11)

    • Developed the core user facing features, including authentication and onboarding

    • Built the Admin Panel enabling the founder to manage users and monitor product usage

    • Created a minimal but professional frontend interface aligned with SaaS best practices

    • Worked in agile sprints, delivering working product increments every two weeks

  3. Launch (Weeks 12–13)

    • Finalized UI polish and QA testing

    • Deployed the app to a production environment

    • Delivered documentation and onboarding support for the founder

Throughout the 90 days, the team maintained a remote first, highly collaborative process, giving the founder weekly demos and updates. This ensured there were no surprises and the product stayed aligned with investor expectations.

The results

By day 90 the founder had a fully functioning MVP:

  • Core SaaS Functionality → User signup, onboarding and feature workflows were live

  • Admin Portal → Provided visibility into user activity and product performance

  • Polished UI → Clean, responsive design that gave investors confidence in product readiness

  • Investor-Ready Demo → The founder pitched with a live product rather than a deck, standing out from competitors

  • Early Customer Validation → With a working app, the founder onboarded pilot users and gathered feedback immediately

Takeaways for startup founders

This example illustrates the power of a 90 day MVP roadmap:

  • Speed matters. With a structured process, founders don’t have to choose between “fast” and “good”

  • Focus creates results. By prioritizing the core value proposition, an MVP can impress investors without scope creep

  • Remote collaboration works. With clear communication, even distributed teams can ship complex SaaS products on tight deadlines

At Harnik Digital this process is repeatable. Every founder engagement is designed to deliver a real, working SaaS product in 90 days, giving startups the momentum they need to raise capital, test markets and grow.
