Season 01 · Los Angeles / San Francisco · Applications open
Your idea isn't the moat. Execution is.
In the vibe-coding era, everyone has the idea — it was never what made a company. We back three things instead: an AI co-founder — a Lumbridge agent with its own Git, compute, and tokens — that makes execution a commodity, the velocity to close the build-learn loop faster than anyone, and founders who'll pivot to Sunday. Twelve months later: a Series A, or set free under MIT.
The factory builds itself. Now it builds with you.
The thesis
The idea was never the moat.
In the vibe-coding era, everyone has the idea, the demo, the landing page by Friday. That was never what made a company. We select — and build — for three things instead.
A factory that makes execution a commodity.
The Lumbridge software factory turns “can we build it” into a solved problem. What's left is the only question worth asking: what should we build next.
How fast the loop turns.
Ship, learn, decide, ship again. We back the teams that close that loop faster than anyone else in the batch — because over a season, speed compounds into a category.
Willing to pivot to Sunday.
We read the team, not the pitch. Taste, grit, and the ego-free nerve to throw out Friday's plan and ship a new one by Sunday. Ideas are disposable. Founders who pivot without flinching are not.
What you get
Three ways we put execution on your side.
So we don't just wire money and wish you luck. We hand you engineers — human and agent — and stay in the build until the company stands on its own.
We fund the season.
Money in the bank and your LLC stood up on day one — plus a founders package so you start as a real company, not a weekend project.
An agent that executes.
A Lumbridge agent deployed as your technical co-founder — with its own Git, database, compute, and tokens. It runs the agentic SDLC around the clock, with Karti steering.
A CTO on your terms.
Architecture, technical hiring, the hard calls. A CTO's judgment on your cap table's terms — not a CTO's slice of equity.
The co-founder
Every company gets an agent co-founder.
Not a tool you operate — a co-founder that executes. We deploy a Lumbridge agent into your company and provision it a full AI-native workspace. It plans, writes, reviews, and ships around the clock. You point; it builds.
Its own repos. Every change lands as a reviewed pull request.
Provisioned and migrated — real state the agent owns and evolves.
On our neo-cloud. The agent never waits in a GPU queue.
Frontier models, metered so thinking is never the bottleneck.
The forge floor
A desk in the room where it's built.
Three to five desks in Los Angeles and San Francisco. Show up and build next to the people building the factory.
Your desk
A dedicated seat on the forge floor — LA or SF. Not a hot desk. Yours for the season.
Gigabit + Starlink
Symmetric gigabit fiber with Starlink on automatic failover. The uplink never blinks.
Neo-cloud, on-prem
A Dell workstation wired into our own compute — frontier Blackwell-class silicon, in the building. No queue, no cold GPUs.
The fleet, on tap
The Lumbridge agent fleet runs beside you on the same floor — spin up engineering capacity the moment you need it.
The team
Small, senior, and ten minutes away.
Lumbridge is Karti and two stealth engineers — battle-tested, hardened, AI-native. No account managers, no junior bench. You're in our Slack from day one, and we hold the line on a real SLA.
The season
One batch a year. Twelve months in the forge.
Raw idea to tempered company, followed the whole way. Every season ends one of two honest ways.
Ore
Selection. One batch enters the forge. LLC, capital, and founders package land on day one.
Forge
Build. The factory runs on your product while you find the true shape of the company.
Temper
Traction. Users, revenue, and the story a Series A can actually believe.
Ship
Raise or release. Close the Series A — or set the work free under MIT, or a license you choose.
The deal
You keep the majority. We earn the rest.
You bring the idea and the cap table. We bring an agent co-founder, the factory behind it, and the hours to push it to the moon. For that we take a real co-founder's stake — never control.
Where you land in the band depends on stage, capital in, and how much we build. We only win when you raise or exit — no fee, no salary, no board seat you didn't offer.
Season 01
Applications are open.
Tell us what you're building — but know we don't read for the idea. We read for how fast you move and how willing you are to be wrong by Sunday. If it's a fit, we'll talk within the week.
