Custom AI Revenue Systems
Scoped per engagementProduction software you never rent back. It runs in your environment, under your license, and on day 91 the source, weights, prompts, harness, and runbook are yours.
See how →03 — Method
Spend on custom only where custom pays. Every capability has four answers.
The cheapest answer is often a tool you already pay for. Configure it, build inside your team, buy from a vendor, or commission a system that does not yet exist. Each capability on your roadmap has one best-fit answer, chosen by fit rather than by what the firm across the table sells.
Quadrant I
Configure
Internal × Off-the-Shelf
An existing tool already in your stack serves the capability. The gap is configuration, not capability.
e.g., lead scoring in HubSpot.
Quadrant II
Build
Internal × Custom
The capability is specific to your motion. No tool serves it well. The system needs to live in your estate.
e.g., pipeline scoring on your win data.
Quadrant III
Buy
External × Off-the-Shelf
The capability is a commodity. The vendor's version is demonstrably better than what you would build.
e.g., calendaring, conversation intelligence.
Quadrant IV
Commission
External × Custom
The capability is custom, but the maintenance burden does not belong inside your team. You own the system.
e.g., a churn-detection system you own on day 91.

04 — What you get
01
Fit
— Enterprise-grade delivery, priced for investor-backed B2B SaaS between $5M and $50M ARR: the tier enterprise delivery groups are not priced to serve.02
Delivery
— Nothing is lost between scoping and shipping. The partner-led team that scopes your system builds it, forward-deployed inside your estate, in ninety days at a fixed fee.03
Method
— Spend goes where it returns most: configure, build, buy, or commission, decided by the diagnostic. No platform alliance or referral fee sits behind the call.04
Ownership
— No rent after delivery. On day 91 you hold the source, weights, prompts, harness, and runbook.05 — Insights
Field notes for revenue leaders.
Founder & Principal Engineer
Most revenue problems are not strategy problems. They are systems that were never built. Your team knows what should happen at each stage; nothing in the stack makes it happen. FusedLabs exists to close that distance.
Mihnea Stoian spent twenty years inside the revenue stack — first as a practitioner at growth-stage B2B SaaS companies, then as an advisor through Loyal VC, where he works with venture-backed founders on their go-to-market motion. FusedLabs is the thesis that followed: the AI shift makes most of what go-to-market consultancies traditionally sell — integrations, dashboards, playbooks — obsolete within a hiring cycle. The replacement is software. So the studio builds it.
The studio stays small so the team that scopes your system has the hours to build it.
