Growth and engineering consultancy

Two founders, two disciplines: growth marketing that builds your audience, and a full engineering practice that builds the software, AI, and data systems behind it. No agency layers, no handoffs.

Brands we've helped grow

What they say

The architect and mastermind behind all of our SEO, from strategy to execution. His work really moved the needle for Live it Up.

Haim Nigri Founder & CEO, Live it Up

My go-to person for all things SEO, across seven years and every project. He doesn’t just hand you solutions, he explains the reasoning.

Charles Lee CEO, S Universe

If you ever pass up the opportunity to work with him, you are missing out on one of the best experiences you can have in your career.

The engineering pillar

And the system.

Marketing brings them in. Software keeps the promise. We design and build what runs behind the experience: full-stack web applications, AI agents that do real work, the data pipelines and integrations that feed them, and automation that earns its keep. One of our founders builds AI-native software for a living, so this is real engineering, not a slideshow.

What they say

Mark is the engineer project leads fight over. Hard problems usually force a trade-off. Mark is the rare case where you don’t have to choose.

Derrek C. Developer Relations Lead, Recall Labs

One of the most adaptive and AI-native engineers I’ve worked with. He operated well beyond what you’d expect, with very little supervision.

Carson Farmer CTO & Co-founder, Recall Labs

He constantly ships, learns, and improves. With the AI shift every tech company now faces, I can’t think of anyone better suited to it.

Danny Zuckerman COO, Recall Labs

We design the system.

We build it.

We ship it.

Production AI systems carrying30+tools across one MCP layer, shipped to real users.
