Technical engineering studio · Web3 & AI

We build the parts of your startup investors
auditors actually check.

Smart contracts, dApps, and AI agent systems for founders building before a raise, and hardening after one. Audit-grade code, whichever stage you're at.

// what we build

One team, the full stack you need before launch.

Blockchain, AI, games, and the web2 software your business runs on — built by the same team that audits it, so nothing gets lost in a handoff.

01 · CONTRACTS

Smart contract development

Solidity contracts for token sales, presales, staking, and treasury logic — written to survive a live raise, not just a testnet.

02 · SECURITY

Audit & patching cycles

Line-by-line review against known exploit classes — reentrancy, oracle staleness, hard-cap overrun, unauthorized withdrawals — with fixes verified, not just flagged.

03 · DAPPS

dApp & wallet integration

Presale widgets, member portals, multi-chain wallet connections — built for the browsers and networks your actual users show up with.

04 · CHAINS

Blockchain clones & forks

Clone or fork an existing chain or protocol and customize it — consensus, tokenomics, and network parameters tuned to your use case.

05 · AI AGENTS

Agentic AI systems

Autonomous agent fleets for operations — support, research, monitoring — designed to run your back office while you run the raise.

06 · GAMES

Mobile & web games

Playable games for mobile and browser, on-chain or off — from play-to-earn mechanics to straightforward gameplay that just needs to ship.

07 · WEBSITES

Websites

Marketing sites, landing pages, and full web presences — designed and built end to end, not templated.

08 · WEB2 SYSTEMS

Business software

Inventory systems, hospital management systems, and other operational software — the non-blockchain backbone your business runs on.

09 · VR/AR

VR & AR applications

Immersive experiences and applications for VR and AR headsets — from prototypes to full builds, on the platforms your users already own.

10 · DATA

Data mining & analytics

Structured data extraction and analysis for clients who need it — scoped to your specific request, handled case by case.

11 · INFRA

Server & deployment ops

cPanel, hosting, and environment setup handled so your site and dApp stay online through launch day traffic, not just the demo.

12 · ADVISORY

Technical due diligence

A second set of eyes on vendor specs, proof-of-funds claims, and technical promises made to you — before you sign anything.

// how payment works

Built for wherever you are in the raise.

Pre-raise founders and funded teams have different cash realities. The commit log doesn't change — the payment terms do.

Upfront

If you haven't raised yet, we can structure a build against a signed technical services agreement — a fixed fee, a deferred payment at close, or a percentage of what's raised. Once you're funded, we work standard milestone billing. Either way, the audit standard doesn't move.

// process

Four commits from brief to launch.

Not a sales funnel — this is the actual sequence a build goes through before we call it shippable.

commit 1 / 4

Discovery & scope

We map what you actually need — contract, dApp, agent system, or all three — and agree on a fixed scope and payment structure in writing.

commit 2 / 4

Build

Contracts, front end, and integrations get built against that spec, with working versions in your hands early — not one big reveal at the end.

commit 3 / 4

Audit & patch

Every contract goes through security review before it touches real funds. Findings get patched and re-checked, cycle by cycle, until it's clean.

commit 4 / 4

Ship & support

Deployment, wallet and payment integrations tested live, and support through your actual launch — not just the handoff call.
