Services

Expertise that funds
the open core.

lean-ctx is Apache-2.0 and free locally, forever. That is CI-enforced and non-negotiable. These engagements buy senior time, not features: rollout, integration and operations expertise from the people who build the engine.

Fixed-price packages

Three packages, no surprises.

Every package has a fixed scope, a fixed price range settled before we start, and a measurable outcome. Work that improves the engine lands upstream in the open core. You never pay for a fork.

Enterprise Onboarding

CHF 6–12k fixed price · 2–4 weeks

Enterprise customers deploying lean-ctx (cloud or self-hosted) for 50–800+ developers.

Deployment setup: cloud provisioning or self-hosted installation on your infrastructure
IdP integration: SAML/OIDC SSO + SCIM provisioning connected to your identity provider
Policy creation: PathJail roots, shell allowlists, model policies, token budgets, rate limits
Admin training: governance console, audit queries, savings ledger verification
Developer onboarding workshop: hands-on session for your engineering teams, recorded

Outcome: production-ready deployment with documented policies and a measured before/after savings report.

Custom Connector / Integration

CHF 5–15k fixed price · 2–6 weeks

Teams that need lean-ctx wired into internal systems or a custom agent.

A production connector (REST/GraphQL/DB/queue) through the provider pipeline
Consolidation into search, knowledge and cache: your data becomes context
Or: embedding lean-ctx in your own agent product via the versioned /v1 API + SDKs
Contract tests against the frozen surface, CI-ready
Handover session + runbook; code delivered under your license of choice

Outcome: your system shows up in ctx_semantic_search and survives engine upgrades (frozen /v1 contract).

Platform Retainer

CHF 1.5–4k per month · 3-month minimum, cancel monthly after

Teams running lean-ctx in production that want guaranteed expertise on tap.

Private support channel with a 1-business-day response SLA
Monthly savings & config review (read modes, budgets, cache hit rates)
Upgrade shepherding: RC validation against your workload before you ship it
Priority triage for issues that block your rollout (fix lands upstream, in the open core)
Quarterly roadmap session: your needs, argued honestly against the public roadmap

Outcome: someone who knows your setup answers within a business day, and fixes land upstream rather than in a fork.

Not ready for a package?

Run an 8-week guided pilot.

CHF 1.5–3k / month · 8 weeks · stops automatically unless you continue

We set lean-ctx up on two of your real repositories, define the success metric with your cost owner up front (tokens, latency, or developer time), and review the signed savings ledger together every two weeks. At the end you have a decision document with your own numbers, not ours.

Week 1: setup on real repos, baseline measurement, success metric agreed in writing
Weeks 2–7: rollout to the pilot group, biweekly ledger reviews, config tuning
Week 8: decision document with measured savings, costs, and an honest go/no-go recommendation

Rules of engagement

Read this before you email us.

Services never gate features.

Everything local is free forever (the local-free invariant is a frozen, CI-enforced contract). If your problem is solved by a config change, we will tell you in the first reply, for free.

Fixes land upstream.

Engine improvements from any engagement are released in the open core under Apache-2.0. You pay for prioritization and expertise, never for a private fork.

Honest numbers only.

Every claim we make in a pilot or onboarding is measured on your repositories with the signed savings ledger: reproducible by you, without us in the room.

Small by design.

This is a focused operation, not an agency. We take a small number of engagements per quarter; if capacity is full, you get a date, not a runaround.

Tell us what you are rolling out.

Two paragraphs about your team, your agents and your repos is enough. We reply within one business day with either a fit, a config tip, or a referral, whichever is true.
