Jason Teixeira.
Fintech engineer. Studio founder. The person on every Sage Ideas engagement — first call, last commit, signed handoff.
Five years inside fintech engineering taught me one thing well: the gap between a product that works in a demo and a product that survives a Stripe webhook retry storm at 2 a.m. is the entire job. Most agencies sell you the demo. The studio that grew out of that experience sells you the part nobody likes building — the idempotency keys, the row-level security, the migrations that don't lose data, the CI gates that catch the bug before the customer does.
Sage Ideas is one operator by design, not by accident. The person who scopes the work is the person who builds it. There is no offshore bench, no account manager, no “lead consultant” who disappears after the kickoff. You buy the keyboard. That is the whole proposition.

The founder story is not decoration. It explains why clients get senior judgment, production engineering, brand thinking, and AI-native execution from the same operator.

Why a one-person studio is the offer, not the limitation.
Most agencies sell you a lead practitioner on the call and hand the work off the moment the contract signs. Sage Ideas does the opposite.
The person who scopes the work is the person who builds it. No bait-and-switch teams.
Fixed scope and fixed price up front, with the artifacts and timelines spelled out before we start.
Custom engagements and retainers are always available — productized tiers are starting points, not ceilings.
Every deliverable is documented and handed off so it survives without me on the next call.
Direct communication. No agency theater, no status calls that should have been emails.
Two ways to start.
Nine fixed-price productized tiers for discrete scopes. Custom engagements, retainers, and ongoing care for everything else.
Track A — Productized
Audit, Sprint, Build, Operate
Nine fixed-price tiers from $750 audits to multi-month builds. Scope is named, deliverables are itemized, timelines are written in. Pick a tier, sign the SOW, ship.
See all tiersTrack B — Custom & Care
Retainers, custom packages, ongoing care
When the productized tiers don't fit, we build a custom engagement. Site Care, Brand Care, and Content Care retainers keep work moving month over month. Open to bespoke scopes — just ask.
