Blargo LLC.
Product studio & software consultancy.
We design, build, and ship our own apps, and we take on client development work. Web, mobile, AI-assisted tooling. Thirty years of engineering behind every line. No fluff, just shipped software.
Thirty years of shipping real software
Blargo is run by Keith Mangold — writing software since 1996, when he started at 17. Three decades of real applications: web, mobile, back-office systems, and the unglamorous parts nobody demos. User discovery, UI/UX, architecture, production incidents — and the judgment to know when technology isn't the solution.
Today that experience pairs with AI-assisted tooling. The tools got faster. The fundamentals didn't change.
Frequently asked questions
What does Blargo LLC do?
Blargo LLC is a San Diego product studio and software consultancy. We design, build, and ship our own products — VIBEpro for farmers markets, GLOBEpro for boutique travel agencies, and Passenger Seat for narrated road trips — and take on select client development engagements across web, mobile, and AI-assisted tooling.
Do you take on client work?
Yes — selectively. We take engagements where 30 years of engineering experience actually matters: real applications with real users, tricky UI/UX, product discovery, or projects that grew faster than their architecture. Right-sized for projects too small for an agency. Email hello@blargo.net with what you're building.
Is Blargo an agency?
No — deliberately not. Blargo is a small, founder-led studio. We take a handful of engagements at a time, typically projects that don't need (or can't justify) a full agency engagement. You work directly with the engineer building your product.
Who is behind Blargo LLC?
Keith Mangold, a software engineer who started coding professionally in 1996 at age 17. Three decades across web, mobile, and product work — engineering, UI/UX, user discovery, and problem solving. He posts regularly on LinkedIn.
Is this vibe coding?
We use AI-assisted tooling every day — and we owned vibepro.io before "vibe coding" was a term (VIBE stood for Vendor Information & Booking Experience). The difference: three decades of engineering means we understand, debug, and stand behind everything we ship. AI speed, engineer accountability.
