AI-native
delivery
AI in the loop from spec to ship: generation, review, refactors, tests, docs. Faster than agencies built before the AI era, with the review discipline a working product needs.
Ship the agent, the eval, and the integration layer your AI product needs to be real.
AI agents, RAG pipelines, vector stores, LLM routing, evals, streaming interfaces, multi-modal inputs. The engineering layer that turns a prompt prototype into a product. One subscription, pause any time, no notice period.
Subscription, fixed build, or white-label, depending on the work.
See all ways to workThe patterns we ship for AI products
AI products fail in predictable ways: no eval, no fallback, no observability, no abstraction over the model. Here are the patterns that survive contact with users.
01
Agent platforms
Multi-step agents with planning, tool use, memory, and recovery. OpenClaw, custom orchestrators, or framework-on-rails.
02
RAG pipelines
Chunking, embedding, retrieval, reranking, citation. Hybrid search where it earns its place, evals on every stage.
03
Vector databases
Pinecone, Qdrant, pgvector, Turbopuffer. Picked per workload, indexed for the queries that matter, observability on hit rates.
04
LLM routing + caching
Anthropic, OpenAI, fallback chains, prompt caching, semantic cache, cost + latency observability per route.
05
Evals + observability
Append-only eval log, regression on every prompt change, latency + cost + accuracy tracked per model. The audit trail an AI product earns trust with.
06
Streaming + multi-modal
SSE or WebSocket streams, partial JSON parsing, multi-modal inputs (image, audio, file). The UI patterns that make AI feel real-time.
Recent work, built and shipped.
Four featured projects Stacklane delivered end to end. Engineering, design, and brand on one cadence, with no internal hires required.
From idea and brand to full product.
Stacklane covers software development, design, motion, brand work, and AI automation. One team, one cadence, one invoice.
From prototype to production AI
We ship the agent, the eval harness, and the integrations that make an AI product something a paying customer can rely on.
01
Book a call
We discuss your goals, timeline, and technical needs to see if Stacklane is a good fit.
02
Subscribe & onboard
Start with a monthly subscription. We onboard quickly and integrate with your team and tools.
03
Build & ship
We work from a shared task list and deliver weekly progress, with clear communication throughout.
04
Scale or pause anytime
Need more speed or less capacity? Adjust, pause, or cancel, no long-term contracts.

AI products that survive the second user.
Engineering for the layer between the model and the customer, where most AI products fall apart.
Real
software
Architected, reviewed, tested, owned. Software you can keep, maintain, and hand over. Not demoware, not prototype code that ships, not unreviewed AI output sent to your customers.
Visible
progress
Progress you can see as it happens, not at quarter-end. Working software, not a slide deck. Pause anytime with 7-day notice.
End-to-end
ownership
Accountable for what ships, not what gets coded. Discovery, design, build, deploy, maintain. One team that owns the outcome.
Frequently Asked Questions
01
How fast will I receive results?
We usually start the same day after onboarding. You'll see progress daily and weekly, with features and improvements delivered continuously based on your backlog and priorities.
02
Who will work on my product?
Senior software developers, 8+ years in production, with AI in the loop end-to-end. We use the AI tooling, we own the architecture, and we sign the review on every PR. Stacklane takes full responsibility for delivery.
03
Is there a limit to how many requests I can make?
No, you can submit as many requests as you want.
04
How do you handle larger requests or features?
Large features are broken down into smaller milestones and delivered step by step. You always see progress and can adjust priorities as we go.
05
Can agencies use this as a white-label solution?
Yes. Agencies can work with Stacklane as a technical partner and offer our software services under their own brand if desired.
06
What if I only have a single request or small project?
We also offer one-off projects with fixed pricing. If you don't need ongoing development, a one-off project may be a better fit.
07
What if I don't like the result?
We work closely with you and iterate based on feedback. Our goal is to build software that fits your needs, not just deliver code.
08
Are there any requests you don't support?
We focus on software development and product design. We are not a good fit for simple marketing websites, very small design-only tasks or non-software services. If you're unsure, we'll help you determine fit during the discovery call.
09
How do we communicate and request work?
You submit requests through a shared backlog or project board. We communicate through tools like Slack, email, and regular check-ins.
10
How does pricing work?
Stacklane works on a flat monthly subscription: predictable pricing, no hidden fees, no long-term contracts. You can scale up, pause, or cancel at any time.
11
Are there any refunds?
We don't refund time already worked. Pause or cancel any time to avoid future charges; both take effect from the next billing cycle.
Let's ship the agent and the eval harness.
Stacklane builds AI agent platforms, RAG pipelines, eval and observability tooling, and the integration layer real AI products need.
