Your biggest customers need more than your product does out of the box.
Trellis lets your SE team build and ship any customization a customer needs — without waiting on engineering, without limits on what’s possible.
Every enterprise deal ends the same way.
Your biggest prospect wants a custom integration before they’ll sign. Your SE knows exactly what they need. But engineering is three months out. You have three options:
Do nothing. Hope the customer doesn’t care. Hope your competitor doesn’t ship it first.
Build it. Burn one to two engineers for two to four months. Make the product worse for everyone else. Ship it, only to discover the customer has moved on.
Build a plugin system. Spend three quarters on infrastructure. Discover that letting customers change background colors doesn’t solve anything.
A single bespoke integration costs $80K–$200K in direct engineering. But the real price is the roadmap work that doesn’t ship while those engineers are occupied. Multiply by every whale customer who needs something custom, and a quarter of your engineering capacity is spent on work that benefits one customer at a time.
The deal dies, or the competitor who can say “yes, we’ll build that this week” wins it.
Your SE says yes.
Engineering stays safe.
The deal closes.
Trellis is an embeddable customization platform. Your engineering team defines extension points — where in the product customers can attach logic. Your SE opens the builder, describes what the customer needs in plain language, reviews the generated workflow, tests it in a sandbox, and deploys through your existing approval process.
The customer gets exactly what they need. The product doesn’t get more bloated. Engineering never touched it. The SE handled it in an afternoon.
Close deals in the POC
Your SE ships exactly what the customer needs during the deal cycle. A $12M renewal isn’t the place to say “it’s on the roadmap.”
Protect your engineering roadmap
Customer-specific customization moves off the engineering backlog entirely. Your CTO stops choosing between the whale customer and product velocity.
Platform economics
Every customization deepens lock-in. Expansion revenue follows from deeper embedding. Churn drops. Your product becomes infrastructure.
Two layers. One guarantee.
Trellisx is the open-source sandboxed runtime. Scripts execute in kernel-enforced isolation — no filesystem, no network, no host environment leakage. The security model is structural, not policy-based. A script physically cannot escape the sandbox.
Trellis wraps it with the agentic builder, governance layer, and enterprise integration engine. Together, they give your SE team the power to build anything a customer needs — within boundaries your engineering team controls.
Define extension points
Your engineering team defines where in the product customers can attach logic — structured mutation boundaries with strict input/output schemas and permission scopes.
SE builds in the builder
Your SE describes what the customer needs in plain language. The agent generates a workflow, maps it to your extension points, and renders it as an inspectable visual graph.
Test in sandbox
Deploy to an isolated environment. Run against sample data. Verify behavior before anything touches production.
Deploy with governance
Configurable approval flows that scale with blast radius. Versioned, auditable, with automatic rollback on anomaly detection. Nothing goes live without the appropriate sign-offs.
Trellisx is open source. Don’t trust security claims — inspect them.
Three deals you’re losing right now.
A fintech customer using your fraud detection platform says: “We need our internal fraud scoring API integrated before we’ll sign.” Before Trellis, this enters the engineering backlog. Timeline: 2–3 months.
Transaction Event
→ Fraud Score Lookup (custom API)
→ Conditional Branch
├─ Score > 80 → Block Transaction
└─ Score ≤ 80 → Allow Transaction The SE handles it in an afternoon. The deal closes during the POC.
A customer trialing your AI support copilot says their agents need internal risk scores from Snowflake before sending replies. Without it, the AI generates suggestions that violate compliance policy. The trial stalls.
Support Ticket Arrives
→ Customer ID Extraction
→ Snowflake Lookup (pre-built connector)
→ Conditional Branch
├─ risk > 80 → Recommend escalation
├─ risk < 20 → Allow automated refund
└─ Otherwise → Standard response The trial unblocks that afternoon. A deal that would have stalled for a quarter closes during the POC.
Your sales analytics customer needs territory-based data filtering. Their territories are defined in Okta groups. Engineering scopes the work: full SCIM provisioning, role mapping, background sync. Timeline: 6–10 weeks.
Dashboard Load
→ Okta Group Lookup (user’s groups)
→ Extract Territory from Group Name
→ Inject Filter: territory = {extracted}
→ Dashboard Renders Filtered Data The extension only filters visibility — it doesn’t alter records. Security signs off because the scope is tiny. Rollout happens before the next QBR.
Three forces.
One deadline.
Non-developers can finally author real logic.
AI-assisted authoring crossed the threshold. SEs and implementation teams can now express genuine business logic as working, auditable code — not pseudocode for an engineer to rewrite.
Enterprise buyers expect platform extensibility.
Salesforce, Twilio, Stripe — they all built platforms. Your buyers now expect the product to adapt to them, not the reverse. If your SE team is still filing engineering tickets for custom work, you’re competing with companies whose SEs ship it in hours.
SE capacity doesn’t scale with pipeline.
Headcount pressure is real and deal complexity is growing. Every bespoke customization ties up an SE for weeks and often requires engineering support. The math doesn’t work: you can’t hire fast enough if every deal requires custom engineering.
Built by operators who lived this gap.
Trellis is built by engineering and growth leaders from Mercury Bank and Finicity (a Mastercard company) who spent years watching SE teams wait in line for engineering bandwidth. We built the infrastructure we wished existed.
