Growth, product, and engineering have collapsed into one role. We run it for you.

Ads, landing pages, AI agents, and the wiring behind them. Built as one system. You buy the system, not the hours.

02 / Approach

The growth engineering team you’d hire if you could find one.

The best growth operators sit at Ramp, Perplexity, Cursor, ElevenLabs. They understand growth, product, and how to build with AI well enough to ship a new system overnight. There are not many of them. The ones that exist are not for hire.

The skills that used to need a whole team (junior code, design, copy, the glue work) are now things AI handles in the background. That leaves the senior free to think about the system and build the part that is actually hard. One person, ninety percent building.

We are that team, on retainer. Senior hands only. We build inside your company, on your data, sized to what your business actually needs.

Then we hand it over. The system keeps running without us. You own it. We sell the work, not the hours, so when the tools get faster you get more, not a smaller invoice.

03 / What we ship

Quick fixes break fast. We build the few that keep working.

Channels get crowded. Generic outreach gets ignored. We build systems that fit your business, target the customers you actually want, and keep performing as the market shifts.

Hey Sarah,

Saw Ramp just closed Series B. Teams going through NY to SF expansion usually hit finance ops bottlenecks in month 3.

Built a system for a company in your stage that saved 11h/week. Worth a 15-min look?

04 / How we operate

Four things you can count on, on every project.

Hover any card for the contrast →

01

Close to the work

No account managers. The person building it is the one you talk to.

01 · Close to the work
TYPICAL AGENCY
Your message goes to an account lead, then a manager, then a junior. Two days for a small change.
SYNTARI
Message the person doing the work. Small changes go live the same day.
02

AI where it actually helps

We use AI when it does the job better than a person. Not just to say we used it.

02 · AI where it actually helps
TYPICAL AGENCY
An old funnel with a chatbot bolted on the end.
SYNTARI
AI handles the busy work. People handle the calls that matter.
03

Outcomes, not hours

We sell the system that gets built. The clock is not the product.

03 · Outcomes, not hours
TYPICAL AGENCY
Hourly retainers that bill you slower as the work gets faster.
SYNTARI
Flat for the capability. Tools improve, delivery improves, the price stays where it is.
04

Measured in money, not slides

We report by the revenue or cost the work actually moved. Nothing else.

04 · Measured in money, not slides
TYPICAL AGENCY
Monthly slides full of clicks, opens, and leads that never close.
SYNTARI
One dashboard. New revenue and money saved, tied to what we shipped.
05 / How it actually runs

Most projects move in three beats. The length depends on the scope.

Start

Get in

We get inside your business. Read what you have, watch the funnel, talk to your customers. Output: one thing worth building.

Middle

Build

Senior hands, on your data, shipping every day. Work goes live as it lands. You see it move.

End

Hand it over

Playbook, training, shared channel. Your team owns it. We stay close for the first two quarters in case anything wobbles.

07 / Availability

Two slots open this quarter.
Three per quarter, ever.

We work in small numbers on purpose. Three projects per quarter. The first call costs you an hour, and by the end of it you know whether there is something worth building.

Build the system.
Keep the keys.

If your next hire is one senior who gets growth, AI, and product, talk to us first. One hour, no slides. You will know if there is a system worth building by the end.
