About Aplis AI

The People Behind Aplis AI

A founder-led software product studio building modern web applications from scratch with agentic development workflows. We combine rapid product delivery with the engineering discipline needed for products people rely on every day.

Mike Chionidis

Founder & Lead Engineer

With over a decade of experience at the intersection of software engineering, data engineering, and AI, I've built scalable systems for some of the world's largest organizations and most innovative tech startups.

As the first engineering hire at San Francisco-based Headquarters Health, I built its virtual concussion-care clinic from the ground up, from AWS infrastructure and patient management to virtual appointments. Today it supports more than 100,000 patients across the U.S.

At Publicis Groupe, I led the technical delivery of marketing technology platforms used by Fortune 500 companies.

I've also contributed to frontier AI model training and evaluation with Mercor, DataAnnotation Tech, and Ethos AI.

As a founding member of AI Academy, I help kids and organizations learn to use AI effectively and responsibly, for the benefit of people.

My approach pairs deep technical expertise with a product-first mindset. I ship fast, using a proven agentic workflow to deliver well-tested, high-quality code. I seek early and frequent feedback from real users, work to understand their needs, and build to solve their pain points.

Katerina Mitsiani

Co-Founder & Full Stack AI Engineer

As a clinical psychologist turned software engineer, I bring an understanding of people to the products I build. My work combines software development with a human-centered approach, creating platforms that are practical, intuitive, and designed around real needs. I also excel at processing and analyzing data, surveys, and research findings, turning complex information into clear insights that inform better decisions.

My work includes building software platforms for organizations such as Great Place to Work and Bluefields Digital, as well as public-sector organizations. I focus on understanding how people work and turning their needs into reliable software that supports their everyday tasks.

I'm also an educator at AI Academy, teaching artificial intelligence to kindergarten and primary school children.

I co-founded Aplis AI with Mike to build products that solve meaningful problems. My background in psychology shapes how I listen to users, understand their challenges, and make product decisions that put people first.

Trusted by ambitious teams.

We’re proud to have partnered with global leaders and exceptional startups to shape what’s next.

What we do

3 ways in

  1. 01

    Strategy

    We map the processes you already run. What consumes your time, what you do inefficiently, and where artificial intelligence can tighten the work, save resources, or raise productivity.

    The starting point, before any build.

  2. 02

    Projects and Platforms

    We build AI projects for your company from scratch. An MVP usually takes one to three months. From the first month you see mechanisms working in practice, and results you can measure.

    For companies that already exist and want to modernize their operations, or make the shift to AI.

  3. 03

    Software Company Development

    We build a technology company from zero and take the technical side end to end: CTO, software architecture, engineering lead, and software development. You can start a software company without a technical background.

    For founders in tech hubs such as San Francisco, New York, and London, with access to funding, investors, or grants. We build. You run marketing, sales, and distribution.
