Custom Acquisition & Retention Software Development
In short
Shattuck Software builds custom acquisition and retention software — paid-ad engines, lead discovery, AI SDRs and conversion systems, plus onboarding, customer-success and renewal tools — that your team owns outright. You get a working demo before you pay.
What we do
Services & Capabilities
Two jobs, one stack you own: software that brings customers in, and software that keeps them. From paid-acquisition engines to retention platforms — production-grade, shipped with a working demo before you pay.
Custom Web & SaaS Applications
We design and ship full-stack web products your team owns outright — no per-seat licensing, no vendor lock-in.
Full-stack delivery in Next.js, FastAPI, or Astro with PostgreSQL, Redis, and clean REST or GraphQL APIs
Multi-tenant SaaS architecture, auth flows, billing integration, and role-based access out of the box
Production-hardened with Docker, Caddy, Cloudflare, and systemd process management
ProofL&S Command Center — a custom platform with 50 data models and 380+ API endpoints, owned outright by the client.
AI Agents & Automation
We build multi-agent systems that replace manual workflows and operate autonomously at production scale.
Orchestrated agent pipelines on Claude, local LLMs via Ollama, and tool-use APIs — reliable, auditable output
Self-improving feedback loops: agent decisions flow back into context so the system sharpens over time
Deployed via systemd or Docker with atomic kill-switches and observable logs — safe to run unattended
ProofDoorLoop Paid-Acquisition OS — 10 AI agents auditing ~300 live ads; Gametime — 11 agents on paid search.
Growth & Marketing Platforms
We wire ad APIs, CRMs, and send engines into one owned system that scales paid and outbound without growing your SaaS bill.
Direct Meta Marketing API + CAPI and Google Ads API integrations for real-time data and automated optimization
Cold-email infrastructure on AWS SES — 10,000 emails/day with deliverability controls and an atomic kill-switch
Lead engines that discover, enrich, and verify B2B contacts autonomously
ProofCold-Email Send Engine (10K/day on SES) + OSS Apollo (38K businesses, 56K verified emails) — both client-owned.
Data, Scraping & Integrations
We build pipelines that collect, verify, and serve structured data at scale — from directory crawlers to API bridges.
Custom scrapers and ETL in Python with self-healing build loops that recover from upstream changes
REST and webhook integrations across CRMs, ad platforms, and internal systems via typed FastAPI / Node adapters
Geo-spatial data layers with Leaflet, ArcGIS, and OpenStreetMap for directory and location-aware products
ProofPortaPottyList — a 50-state, 630+ page directory built and maintained by a self-healing pipeline with zero manual upkeep.
Internal Tools & Dashboards
We replace generic project-management and reporting SaaS with purpose-built tools that fit exactly how your team works.
Custom dashboards with live data from your existing APIs, databases, or third-party services — no BI vendor
Workflow automation and internal CRUD apps in Next.js or Astro with TypeScript, built to last
Role-based access, audit trails, and data models designed from your operations — not a template
ProofL&S Command Center — a bespoke PM + customer-success tool that replaced four separate SaaS subscriptions.
Cloud, Infrastructure & Reliability
We set up and harden the infrastructure layer so your product stays up, scales cleanly, and costs what it should.
Zero-downtime deploys with Docker, Caddy, and Cloudflare — SSL termination, WAF rules, DDoS mitigation
OAuth and credential management, environment isolation, and secrets hygiene from the first deploy
systemd service management, health checks, and log pipelines so autonomous workloads run without babysitting
ProofOSS Apollo + the Send Engine run autonomously in production via systemd, with observable logging and atomic controls.
Why us
Why Shattuck Software
Custom software, built the way it should be: owned by you, built by a senior operator, shipped fast.
You own the code — no subscriptions, no lock-in
Every system is yours outright: source, infrastructure, deployment. Across our network, clients have replaced ~$3,496/mo in SaaS fees with software they own permanently. No vendor can raise your price or hold your data hostage.
A senior operator builds it — not a junior team
Mikee Shattuck codes your project directly — 15 years hands-on across full-stack engineering, AI systems, and growth. You get principal-engineer thinking on every line, not a PM relaying requirements to an offshore queue.
Working demo before you pay — days, not months
We ship a working demo within one day for a $100 refundable deposit. No 12-week SOW negotiation, no bloated sprints. You see real software running against your actual use case before committing to a full build.
AI-native and full-stack
We build with the full modern stack and embed AI where it earns its place — autonomous agents, self-improving loops, API orchestration at scale. 47 live products shipped. Not a pivot to AI; it's how we've built from the start.
Ship a working demo before you pay a cent.
We scope it, build it, and hand you something live — within one business day. A $100 refundable deposit is all it takes to start. If the demo doesn't impress you, you owe us nothing.
