Resourcing is the bottleneck
The campaign is ready, but the form, tracking, landing page, notification, or CMS change needs someone technical to ship it.

the problem
You're constantly blocked by engineers
You've done the research and created the strategy. Now you just need engineering resources to get it done.
"We'll put it on the roadmap"
Your team has goals, but product and engineering have their own goals.
All you need is a one-time setup
AI pipelines, A/B testing, and CMS tooling all promise leverage, but all you need is someone to install them.
the fix
A fractional marketing engineer for B2B teams.
Bring in an experienced engineer with a marketing mindset. We'll research, install, build, and hand-off any technical levers your marketing team needs.
Marketing brain for AI
Clean up your team's agentic workflows. Establish consistent brand voice, guidelines, and systems for agents to run in.
Tools
- Claude
Codex
Email, push, and in-app notifications infra
Set up tooling for lifecycle messaging, product nudges, or triggered campaigns, like Braze, Iterable, or Knock, without bothering the product roadmap.
Tools
Knock
Website maintenance
Build, edit, and instrument landing pages, conversion flows, analytics, and campaign pages for B2B growth teams.
CMS setup or migration
Set up or migrate your CMS so your team can publish without continual engineering support. Set up tools like Sanity, Ghost, or Contentful for your team.
Set up A/B test infra
Install experimentation tooling, create first tests, and leave your team with a repeatable launch process. Use tools like Eppo, PostHog, or LaunchDarkly to run your tests.

the process
How it works: One month from kickoff to handoff.
We start with what you need, scope the project and technical decisions, ship/install/build, and then set your team up with a handoff plan for usage.
Sign / kickoff
We align on the one-month engagement, working cadence, team access, and the marketing levers we need to unblock.
Scoping
We turn the backlog into a clear sprint plan: what ships, what gets deferred, and where engineering input is needed.
Tool research / recommendations
Optional support for choosing AI, CMS, experimentation, messaging, or analytics tools before anything gets installed.
Installation
We implement the pages, workflows, events, integrations, tests, and technical marketing assets needed for launch.
Handoff, plan, and strategy
Your team gets documentation, recommendations, and a practical roadmap for what to run next after the sprint ends.
case studies
What fractional engineering unlocks.
One-time technical investments that give marketing teams lasting, independent leverage.
Braze infrastructure for 5M users
Installed the Braze SDK, event ingestion, and user attribution, then proved the setup with initial campaigns—giving Phantom’s marketing team independent control of email, push, and in-app content cards across its mobile apps.
A publishing workflow without deploys
Replaced hardcoded Next.js articles with Sanity so marketing could independently publish product launches, blog posts, and company announcements without engineering or risky production deploys.
Many agents, one company brain
Normalized context from Slack, Notion, Granola, and tribal knowledge into an AI-ready company brain, aligning landing pages, workflow docs, and client messaging around one consistent brand voice.

Frequently Asked Questions
Who is this for?
B2B growth and marketing teams with technical marketing work blocked by engineers.
Is this consulting or implementation?
Both, but the emphasis is implementation. Our goal is to install, implement, or build technical systems that give your marketing team levers.
Do you work with our engineering team?
Yes. We can work directly with engineering to understand constraints, propose safe approaches, and keep marketing work from creating surprise maintenance burden.
How long is the engagement?
The target engagement is one month at a fixed cost, focused on the highest-leverage technical marketing backlog we can clear in that window.
What happens after the sprint?
You get a handoff, documentation, and a recommended plan for experiments, tooling, and implementation priorities your team can continue with.
