Custom solutions
When the off-the-shelf doesn't exist.
Some workflows are too specific, too proprietary, or too valuable to hand to a vendor. We design and build them with you, on your stack, with your data, owned by you.
When custom is the right call
Four shapes that don't fit a vendor.
01
Proprietary workflow with no SaaS for it
You've looked. The vendors approximate it. None of them get the half that actually matters. We build the half that matters.
Recent shapes
Underwriting copilot for a specialty insurer · Spec-to-quote agent for a precision-machining shop
02
Sensitive data that can't leave your perimeter
Regulated industry, customer PII, IP-heavy product. The agent runs in your VPC, on your models, against your warehouse.
Recent shapes
Clinical-record summarization in a HIPAA boundary · Source-code review agent in an air-gapped repo
03
High-stakes decisions that need full audit
Every input, prompt, retrieval, and output captured. Replayable. Reviewable by counsel. Not a black box.
Recent shapes
Compliance triage with reviewer hand-off · Pricing exception engine with override trail
04
A category we haven't named yet
You have a hunch about what an agent could do that nobody is shipping. We'll prototype it in two weeks and tell you if it's real.

How a custom engagement actually goes
Shape. Spike. Decide.
Custom doesn't mean open-ended. It means a sharper definition of done than a SaaS contract.
- 01
Discovery
3–5 days
Working sessions with the people who do the work today. We trace the workflow, find the seams, and pick the wedge.
- 02
Spike
2 weeks
A working prototype on your data. Not a slide deck. We use it to learn what's actually true vs. what we assumed.
- 03
Decide
1 week
Build it, kill it, or change shape. We tell you which we think and why. You decide.
- 04
Ship
4–10 weeks
Production agent inside your stack. Eval harness, observability, RBAC, runbook, on-call rotation.
- 05
Operate
Ongoing
We stay until the team that owns it is faster with it than without us. Then we leave the lights on.
When this isn't the move
We're not the right call if
- × You want a SaaS contract you can sign and forget
- × You don't have a clear owner on your side
- × You want a chatbot you can sticker on a homepage
- × The workflow you want changes weekly
For those, the right move is one of our pre-shaped pillars or a vendor we'll happily point you to.
How we work
Discover. Spike. Ship.
One engagement, three phases. Outcomes shipped, not seats sold.
Consult
Map the foundation that's actually missing.
A 30-minute consultation, then a focused audit. We trace the systems you have, the seams between them, and the agentic surface that should replace the manual middle.

Questions
The questions sophisticated buyers ask before they commit.
Four answers. The full library lives at the homepage Q&A.
Q1 Are OsmoSync custom builds the same as every other engagement?
Are OsmoSync custom builds the same as every other engagement?
The kernel is shared. The layer model, the build order, the orchestration patterns, the Business OS scaffolding. The configuration is yours. Your context, your data sources, your agents, your rules, your brand, your dashboard. Two OsmoSync clients have the same shape; they have completely different bodies.
Q2 How is a custom build different from hiring an internal team?
How is a custom build different from hiring an internal team?
An internal hire is one person's brain. OsmoSync gives the company an OS that holds the founder's context permanently, doesn't quit, doesn't forget, and doesn't take its institutional knowledge with it when it leaves. An internal team builds at Level 2 in a quarter, because that is what one team can ship. OsmoSync builds to Level 4 in the same window because we have built dozens of these.
Q3 Do I own the OS after OsmoSync builds it?
Do I own the OS after OsmoSync builds it?
Yes. The OS lives in your environment, your accounts, your data, your domains. Your context, your agents, your asset, permanently. No rented runtime, no vendor lock. When the engagement ends, the OS keeps running.
Q4 What happens when an AI model improves or a tool gets disrupted?
What happens when an AI model improves or a tool gets disrupted?
The OS continues. Models and tools live inside the layers. Better Claude model? Layer 4 inherits it. Cheaper voice? Layer 6 swaps in. Underlying automation tool disrupted? Migrate the components, the rest of the OS does not notice.

Tell us the shape.
If your problem doesn't have a vendor, that's the conversation. 30 minutes, your stack, your hardest workflow.
