About
We’re
Sir Vendor Inc
Sir Vendor Inc is a web & app development company founded by William Lopez. We design, build and launch fast, custom websites, web apps and mobile apps end-to-end — and we stay on to support them. You work directly with the team building your project.
We started Sir Vendor Inc because too many good projects get lost between salespeople, project managers and developers who never actually speak to the client. We do it differently: you work directly with the team building your project, from the first sketch to launch day.
Across 8+ years of building for the web, we’ve shipped 120+ projects — marketing sites, online stores, web apps and mobile apps — for founders and businesses around the world. We care about clean code, honest timelines, and work you actually own.
What we stand for
How we work
Honesty first
Straight advice and realistic timelines, even when it’s not the easiest thing to hear. No inflated promises to win the job.
You own everything
All the code, design files and assets are yours. We build on standard, open tools, so you’re never locked in.
Direct communication
You talk to the team doing the work — with regular updates and no account-manager telephone game.
