— FULGURBUILD ON BITCOIN
— Fulgur

Come back home. Build on Bitcoin.

An accelerator for founders who want to build on global, permissionless freedom money: Bitcoin. Fully funded residency at the Network School. Real investors. Rolling monthly cohorts.

01 — Why Bitcoin

The revolution has been waiting for serious builders.

Bitcoin is freedom money. Global, permissionless, private. The only monetary network with no CEO, no foundation, no committee to capture. The infrastructure is maturing fast. Founders and venture firms have spent a decade chasing token speculation instead of bringing bitcoin to billions, and we are here to redress the balance.
01

Freedom money

Global, permissionless, private. Money that can't be frozen, seized, or inflated away.

02

Half of everything

The market for a digital store of value is worth half of everything. The largest opportunity on the planet sits right here.

03

Underbuilt by default

A decade of token speculation starved the application layer. Bring bitcoin to billions and you own the primitives.

02 — What you get

Three things, done properly.

Scholarships, ideas, capital. No theatre.
01
Scholarships, earned
You arrive at the Network School paying your own way. Once you've shown us something — any kind of traction or commitment — we put you on a scholarship. Could be a month. Could be six.
02
Fundable ideas
Education, mentorship, and direct access to operators who've already built on Bitcoin and Lightning. We have a shortlist of fundable ideas ready for the right teams.
03
Investment
Cyphertank Demo Day. Investors compete to back the strongest teams. Win the room and you're on the plane to the Cyphertank Final in Lugano.

An offer from us is an invitation, not a free ride. Once you're here, we're watching. Ship something, make progress we can point to, and we'll put you on a rolling scholarship.

03 — Ideas

Fulgur will fund these ideas today. Why not you?

Seven open problems. A Bitcoin-native builder can ship any of them in a month.
01
Savings
Bitcoin-only savings apps with stablecoin rails. Relai / Strike-style products for Asia. Simple UX, recurring buys, self-custody optionality. The challenge: can you get 100k users buying $100 of bitcoin a month?
02
Markets
Trading infrastructure and prediction markets. Next-gen exchanges, derivatives, and BTC-denominated prediction venues. Compliance-aware venues built for the depth and sophistication bitcoin markets now demand.
03
Finance
Bitcoin neobanks, primitives, and lending. Mortgages, pensions, treasury management, BTC payroll. Retail and institutional credit markets, DeFi-style or CeFi-hybrid. Financial products built on a bitcoin balance sheet with conservative LTVs.
04
Yield
Bitcoin yield from economically productive sources. Lightning routing, liquidity marketplaces, hash-rate-linked products. Yield that comes from actual economic activity on the bitcoin network, not from Ponzi mechanics or wrapped tokens.
05
Payments
Universal bitcoin payments. B2C, B2B, and AI-agent payments across the L2 stack (Lightning, Spark, Ark, e-cash). The challenge: private, permissionless, seamless payments at every transaction size.
06
Institutional
Institutional custody and security. Fireblocks / Anchorage-class infrastructure for the bitcoin era. MPC, key management, audit, insurance wrappers. The security layer of the bitcoin economy.
07
Bitcoin × AI
Where bitcoin meets AI. Machine-to-machine payments over Lightning. AI agents that settle in bitcoin. Bitcoin firewalls as the anti-sybil primitive. Bitcoin as the native settlement and access-control layer of the agent economy.

Eight detailed problems — with specific markets, partners, and metrics — that Fulgur will fund today.
Request for Startups

You're not just getting a programme. You're joining a community.

01

Community

Live and work alongside the ambitious people already building at NS. Solo operators, seasoned founders, senior researchers, venture partners — the people pulling the frontier forward.

02

Co-founders

Arriving solo? Good. Week one includes co-founder matching, informal onsites, and the chance to meet the people you'd actually want to build with.

03

Team building

Find your engineer, your designer, your commercial partner. The density of shipping talent at NS makes the hire that would take a year somewhere else take a week here.

04 — How it works

Rolling monthly cohorts. You arrive on the 1st.

You stay as long as you're building.
01
Apply
Pick your cohort up to three months out. We review on a rolling basis.
02
Arrive
Land on the 1st. Onboarding, co-founder matching, first-week education led by Plan B.
