How we work
The speed of AI,
the judgment of senior engineers.
Most agencies quote in months. We compress the same work into days by putting AI coding agents in the hands of experienced engineers, then keeping a human accountable for every line that ships.
01
Scope in hours
We meet, map the problem and return a clear plan and fixed timeline, usually within a day, not a fortnight of back-and-forth.
02
Build with AI leverage
Senior engineers paired with AI coding agents compress months of work into days, without cutting corners on quality.
03
Ship & iterate
You see working software early and often. We deploy, gather feedback and refine in tight loops until it's right.
04
Scale & support
From launch to growth, we maintain, optimize and extend, or augment your team with our specialists as you scale.
Global by default
A remote-first studio with a worldwide client base.
We collaborate with innovative partners across the globe who believe in our vision. Together we're building technology that delivers meaningful results, on every timezone.

Questions, answered
What does Null Studio build?
Custom AI agents (voice receptionists, appointment setters, chat and workflow agents), full web and mobile products, business automations, and AR/VR/XR systems — designed, built and run end-to-end by a senior team of nine.
How can you ship in days when agencies quote months?
AI coding agents handle the mechanical majority of implementation while senior engineers direct architecture and review everything; we build in vertical slices so a working workflow exists within days; and we scope ruthlessly to the workflow that creates value first.
How much does an AI voice agent or receptionist cost?
Usage runs roughly $0.07–$0.20 per call-minute. Builds range from about $1,000 for a single-purpose agent to $5,000–$25,000 for production systems with CRM, calendar and compliance integrations, plus a monthly service fee that covers monitoring and tuning.
Do you work with clients outside the US?
Yes — our clients span the US, UK, Europe, Singapore and beyond. The team works across timezones, and most engagements are fully remote with daily async updates and live preview links from day one.
Can you take over or fix an existing project?
Yes. We regularly step into existing codebases and stalled builds — as fractional CTO support, rescue engineering, or team augmentation — after a short technical audit to scope what's actually needed.
