AI Development

Most AI projects die in the demo. Yours gets to Friday.

We design, build, and deploy production AI: custom assistants, retrieval systems, and workflow automations wired into the tools your team already uses.

Custom GPTs RAG / Vector Search Voice Agents Workflow Automation Fine-Tuning

The last step is a person. Nothing sends on its own.

What we build

We’ve built these enough times to stop estimating them.

Every engagement is custom, but the underlying patterns repeat. These are the surfaces where AI consistently moves the needle for marketing and operations teams.

01

Custom GPTs & assistants

Branded, persona-driven assistants trained on your voice, your data, and your guardrails. For support, sales, copywriting, and ops.

  • Tone-locked outputs
  • Auth-gated access
  • Tool / function calling
02

RAG & knowledge systems

Search your handbook, your contracts, your past creative, and get a real answer with citations, not a hallucination.

  • Vector + hybrid search
  • Source citations
  • Slack / web / API surfaces
03

Workflow automation

Long, repetitive marketing ops (brief generation, asset routing, reporting) replaced with deterministic pipelines.

  • n8n / Make / Zapier
  • Python + LangGraph
  • Human-in-the-loop checkpoints
04

Voice & phone agents

24/7 inbound + outbound voice agents that book, qualify, and escalate. With a human-quality script and call analytics.

  • Vapi / Retell / Twilio
  • CRM write-back
  • Transcript scoring
05

Fine-tuning & evals

When prompting plateaus, we fine-tune. With proper eval suites so you know when the model is actually getting better.

  • OpenAI / Anthropic / OS
  • Eval harnesses
  • Cost-quality tradeoff plans
06

AI strategy & audits

Where does AI actually belong in your stack? We map opportunity, risk, and ROI, and tell you what not to build.

  • Workflow inventory
  • Build / buy decisions
  • Governance & data policy
How we build

From whiteboard to production in five.

A repeatable engagement model that gets you to a working system fast, without skipping the boring parts that make it actually work in 6 months.

01 · Discover

Map the problem

Workflow walk-through, data audit, success metrics agreed before any prompt is written.

02 · Prototype

Spike, don’t sprint

A scrappy v0 in days, not weeks. Real data, real users, real feedback.

03 · Engineer

Production build

Auth, logging, evals, fallbacks, rate limits: the unsexy 80% that keeps it alive.

04 · Deploy

Wire to your stack

Slack, Notion, HubSpot, your site: wherever your team already lives.

05 · Operate

Tune & observe

Weekly evals, cost dashboards, prompt versioning. AI that gets better, not flakier.

The stack

We’ll use whichever model doesn’t wake you at 3am.

We don’t have a favorite model. We have favorite outcomes. The stack flexes to the job, sometimes that’s a $0.0001 prompt, sometimes a fine-tuned 70B with a vector store and a queue.

  • ModelsOpenAI, Anthropic, Google, Mistral, Meta Llama 3, plus open weights for sensitive data.
  • OrchestrationLangGraph, LlamaIndex, custom Python: whatever survives a 3am pager.
  • Vector & dataPinecone, Weaviate, pgvector, Supabase, BigQuery: driven by your data residency.
  • SurfacesSlack, Notion, HubSpot, Webflow, custom dashboards: your team’s existing tools first.
  • ObservabilityLangSmith, Langfuse, custom evals, because you can’t improve what you can’t measure.

Where it lands

Real systems, for teams that have to use them Monday.

A few of the patterns we ship most often. Each one started as “wouldn’t it be great if…” and ended as a button in someone’s Slack.

Marketing Ops

Brief & deck generator

Strategy team feeds in a goal + brand context, gets back a media plan, creative brief, and pitch deck: pre-formatted, on-tone, ready to edit.

StackGPT-4o + RAG + Notion API
Sales

Inbound voice qualifier

24/7 voice agent answers leads, qualifies BANT, books to calendar, writes the recap to HubSpot: handing off only the hot ones.

Coverage24/7 in 3 languages
StackVapi + Twilio + HubSpot
Customer Support

Knowledge-grounded helpdesk bot

Trained on your help center, past tickets, and product docs. Cites sources. Escalates with a transcript when it’s out of depth.

StackClaude + Pinecone + Zendesk
Content

SEO content factory

Keyword cluster → outline → draft → editorial review queue. With brand voice locked in and human approval before publish.

StackGPT-4o + Ahrefs + Webflow

The toolkit, opinionated.

Tools we reach for first. Always evaluated against the alternative.

FAQ

Questions we get asked, including the rude ones.

If yours isn’t here, drop a note. We answer every inquiry inside one business day.

Will my data train someone else’s model?

No. We use enterprise endpoints with zero-retention contracts wherever possible (OpenAI ZDR, Anthropic, Azure OpenAI). For sensitive data, we deploy open-weight models on infrastructure you control. Data policy is part of the audit, not an afterthought.

How long until something is in production?

For a Build Sprint, expect a working v0 in 1–2 weeks and a deployable system in 4–8. We resist the consultant move of “we’ll have a strategy deck for you in Q3”, momentum is the project.

Can you work with our existing AI / engineering team?

Frequently the best way. We pair with internal teams as a force multiplier. Bringing patterns, tooling, and prompt engineering depth, then handing off cleanly. No black-box code.

What if the model “gets dumber”?

Eval suites and prompt versioning are built into every project. When a model regresses (it happens), we catch it on the dashboard. Not from a customer ticket. Quarterly model refresh is part of the embedded retainer.

Do you handle compliance / SOC 2 / HIPAA?

We’re not a compliance vendor, but we build to your control set. We’ve shipped systems inside SOC 2 Type II, GDPR, and HIPAA-adjacent environments. We’ll route data and choose models accordingly.

What does “production” mean to you?

Auth, logging, evals, fallback paths, rate limits, cost monitoring, prompt versioning, on-call runbook, and a human-in-the-loop where stakes are high. If it’s not there, it’s a demo, not a system.

Let’s build

Everyone’s seen the demo. Fewer have shipped the system.
