The Engineering Behind
Priority-First Coordination
StitchLink doesn't use AI to guess your schedule — we use deterministic math to solve it. Here's how.
Mandatory-First Scheduling
Traditional scheduling is a “democracy” where everyone's time is treated equally. This is why group polls fail — they generate noise instead of decisions.
Core Principle
If a “Required” attendee isn't available, the time slot doesn't exist. Period.
Result: We eliminate 90% of the “back-and-forth” by enforcing team hierarchy at the algorithmic level.

What StitchLink sees
🔒 Busy — 9:00 AM to 10:00 AM
✅ Free — 10:00 AM to 2:00 PM
Zero-Retention Architecture
Fetch → Process → Forget
We don't want to “read” your calendar — we want to coordinate it. Most scheduling tools are a liability because they store your sensitive meeting titles.
Ephemeral OAuth
We fetch free/busy status, then discard the connection. No event content is ever extracted.
Row-Level Security
Built on Supabase with RLS policies on every table. The public API surface never exposes cross-tenant data.
Architectural Blindness
We can't see your event details — not “won't,” can't. The data is never fetched in the first place.
Deterministic Coordination Engine
While other tools bolt “AI” onto scheduling and hope for the best, StitchLink uses constraint-satisfaction solvers — the same class of algorithms used in airline crew scheduling and factory optimization.
Zero Hallucination Risk
LLMs can suggest impossible times. Our engine mathematically guarantees that every proposed slot satisfies all constraints.
Deterministic = Repeatable
Same inputs, same output, every time. No randomness, no “sorry, the AI was confused” moments.
Priority-Weighted Optimization
Required attendees are hard constraints. Optional attendees are soft preferences. The solver maximizes total attendance.
Collect Constraints
Required attendee calendars, duration, date range
Apply Hard Constraints
Eliminate all slots where required attendees are busy
Optimize Soft Constraints
Maximize optional attendee coverage + time preferences
Return Ranked Results
Top 3 slots with match scores — deterministic every time
The Production Stack
To ensure “Zero-Touch” speed, we abandoned legacy “no-code” builders for a production-grade environment. Every layer is SOC 2 certified.

Why This Architecture Wins
Legacy players like Google and Microsoft are incentivized to centralize your data — it's their business model. They cannot adopt a Zero-Retention approach without abandoning the data pipeline that funds their entire ecosystem.
Privacy as Architecture
Our depth isn't in AI — it's in the architecture. Privacy isn't a feature toggle; it's baked into every data flow.
Math, Not Guesswork
Constraint solvers produce provably correct results. No training data, no bias, no hallucinations.
Sustainable by Design
Stripe-integrated from day one. We're a paid product — not a free tool that mines your data to survive.
