Tell us what you're trying to ship.
Five problems we've shipped before, usually more than once. Pick the closest match, we'll tell you in 72 hours what it'd take.
01
From $8k · 3–6 weeks
AI agents and multi-agent systems
Agent systems built to run in production, handling customer conversations, internal workflows, or domain-specific reasoning. Agents with tools, memory, and structured output, not chatbot wrappers.
The founder problem
"I want AI in my product, but ChatGPT wrappers feel cheap and OpenAI's assistants API breaks under load. I need something that holds up in production."
Our approach
Custom orchestration over hosted agent APIs, specialist agents over monoliths, and cost optimization through model routing. Built to scale.
Things we've shipped
- →Multi-agent sales triage for Lonesyte
- →RAG-backed internal Q&A for an enterprise client
- →Tool-using agents for an Ops automation suite
- →Domain-tuned drafting agents (fintech, NDA)

02
From $3k · 1–3 weeks
Vibe-coding fixes and rescue
When Lovable, Cursor, Bolt, or v0 got you to a working demo but it buckles in production. We take the AI-generated codebase you already have and make it secure, scalable, and maintainable, no rewrite from scratch.
The founder problem
"I shipped a prototype with AI tools, users actually like it, but now it's slow, insecure, and I'm scared to touch the code. I need someone senior to fix it before it falls over."
Our approach
We audit the generated codebase, close the security holes (auth, row-level security, leaked keys), untangle the architecture, add tests and observability, and hand back a codebase a human can maintain. Rescue over rewrite, unless a rewrite is genuinely the cheaper path.
Things we've shipped
- →Production-hardened a Lovable-built SaaS before launch
- →Auth + RLS fixes on an AI-generated backend
- →Refactor and test suite for a Cursor/Bolt prototype
- →v0 frontend wired into a real, secured API

03
from $6k · ~4 weeks
SaaS MVPs, end to end
A working product in production, with auth, payments, and admin, built to scale past PMF without a rewrite. Not a Figma mockup or a no-code stitch-up.
The founder problem
"I've validated the idea, talked to users, and now I need someone who can build it. The real thing, not a no-code prototype."
Our approach
Fixed 4-week Phase 1 sprint to a Core MVP in production. Production-ready stack from day one. Weekly working demos. Later versions ship as follow-on phases. You get a product that survives the first hundred users.
Things we've shipped
- →BuildAI creator-economy SaaS, 3.5 wk launch
- →Reverbly subscription SaaS
- →Folio portfolio tracker

04
From $4k · 1–3 weeks
Custom automation and integrations
When n8n or Zapier isn't enough. Bespoke automation flows that hit real APIs, handle real edge cases, and don't break when a vendor changes their JSON schema.
The founder problem
"My team is drowning in manual work, pulling reports, updating CRMs, scraping data, sending follow-ups. I need this automated yesterday."
Our approach
n8n for the 80% case, custom Node/Python for the 20% n8n can't handle. Built with retries, error handling, and observability, not held together with duct tape.
Things we've shipped
- →Elara, 14 ops workflows replaced
- →CRM-to-warehouse sync for a fintech
- →PDF lab-report pipeline (healthcare)
- →Multi-source enrichment for SDR teams

05
From $12k · 4–8 weeks
Multi-tenant SaaS infrastructure
B2B SaaS architecture done properly: tenant isolation, role-based permissions, billing per workspace, audit trails. The boring stuff that breaks you in year two if you skip it.
The founder problem
"We're selling to teams, not individuals. I need workspaces, seats, admin roles, per-tenant data isolation, and I need it right the first time."
Our approach
Row-level security from day one. Workspace-scoped everything. Per-tenant rate limiting, audit logs, soft deletes. Designed so SOC2 doesn't require a rewrite later.
Things we've shipped
- →XPANDIFI multi-tenant workspace infra
- →Sentry-RX healthcare RLS rollout
- →Per-tenant Stripe Connect billing
- →Audit-log infra for a B2B compliance SaaS

FAQ
Questions founders ask before booking.
Can you combine services in one engagement?
＋
Yes, most projects do. A typical MVP includes both AI agents and multi-tenant infra. The five categories above are how we describe what we do, not how we bill.
What if my project doesn't fit these five?
＋
Tell us anyway. The categories above are the patterns we've shipped most often, they're not exhaustive. If we can't help, we'll usually know someone who can.
Do you work with non-technical founders?
＋
Often. We're used to translating product thinking into engineering decisions.
Can you take over an existing codebase?
＋
Yes, with caveats. We do a free 2–3 hour code review first. If it's salvageable, we quote. If it's not, we tell you.
