We integrate LLMs, RAG and automation into products that actually have to work. The model is one component; the value lives in the product, data and UX around it.
AI is a capability, not a product. Most "AI development" pitches sell the model — but the model is the easy part. The hard work is everything around it: the data pipeline that feeds it, the retrieval that grounds it, the guardrails that keep it honest, the UX that makes it usable, and the integration into systems your team already runs. Ostohlo is a product-engineering studio — we build systems, not demos — and we apply AI only where it measurably earns its place inside real product engineering.
So let's be blunt. An LLM won't fix a broken workflow, and a chatbot bolted onto a bad product just makes it faster to complain about. We treat AI like any other component: an engineering decision with costs, failure modes and a job to do. Sometimes the answer is a model with retrieval; sometimes it's a deterministic rule that never hallucinates. We tell you which, and build the one that ships.
The market is flooded with "AI-powered" everything, and most of it is a thin wrapper around someone else's API — impressive demos that quietly fail in production. We start from the use case and the numbers, not the buzzword. If a plain feature beats a model, we build the feature.
A model that confidently invents an answer is worse than no feature, especially in fintech or support. Trust is engineered, not promised: we ground responses in your data, cite sources, constrain outputs, and add evaluation so you see the error rate instead of hoping it's low.
Your data is the real asset, and it's often messy, siloed or sensitive. Feeding it to a third-party model raises real questions about privacy and leakage. We design retrieval and access so the model sees only what it should, and run open or on-prem models where compliance demands it.
The gap between a working notebook and a feature users rely on is huge — auth, rate limits, cost control, latency, fallbacks, logging, monitoring. This is where most AI projects stall, and it's exactly what we're built for, because we ship production software for a living.
Tell us about your task — we'll come back with architecture and an estimate within 24 hours.
Get an estimateWe wire language models — hosted or open-weight — into your product through clean, testable APIs, with streaming, retries, token-budgeting and cost controls. You get a maintainable integration, not a fragile script, and keep the freedom to swap the model later.
Retrieval-augmented generation grounds answers in your own content, so responses stay factual and current. We build ingestion, chunking, embeddings and vector search, then tune retrieval quality — the biggest lever for accuracy — and expose it as fast search over your knowledge base.
Assistants that do more than talk: they call tools, read your data, and take scoped actions for the user. We design the boundaries carefully — what it can and cannot do — so it's genuinely useful without becoming a liability, with a human in the loop where the stakes justify it.
The highest-ROI AI often lives in the back office — classifying tickets, extracting fields from documents, drafting replies, triaging queues. We embed models into these pipelines with clear pass/fail rules and human review, turning slow manual steps into fast, auditable automation.
Generation and ranking applied with judgment: copy, summaries, personalized feeds and recommendations tuned to your metrics. Because AI systems increasingly discover content, we also handle findability — see our take on optimizing for AI search.
You can't improve what you don't measure. We build evaluation harnesses on real test sets, track accuracy, cost and latency over time, and add guardrails — input validation, output constraints, moderation and monitoring — so a model change never silently degrades your product.
Our credibility is engineering depth, not an AI slide deck. We build and operate our own products across fintech, SaaS, marketplace and adtech — including Adgora, an ad network with algorithmic, data-driven components running at real scale. That's the honest evidence: we know how to ship data pipelines, low-latency services and production systems that AI features depend on. We don't claim a headline AI product we haven't built — we claim the engineering foundation that makes applied AI work, and we bring it to yours. See more in our portfolio.
We begin with the job to be done and the metric that defines success, then ask whether AI is even the right tool. Half of good AI engineering is knowing when not to use a model — which keeps you from paying for inference a simple rule would handle.
Model quality is capped by data quality. Before any prompt engineering, we assess what data you have, how clean it is, and what retrieval it supports. Often the biggest wins come from fixing the pipeline, not tuning the model.
We don't marry your product to one vendor. We design behind an abstraction so you can move between hosted and open models as price, quality and compliance shift. The model is a replaceable part; your product logic and data are not.
Every AI feature ships with evaluation and guardrails from day one, not bolted on after an incident. We define acceptable error rates up front, monitor them in production, and give you the dashboards to decide when the system is good enough to trust.
Both, but our sweet spot is applying AI inside an existing product or one we build with you. AI is rarely the whole product; it's a feature that makes a good product better. We integrate LLMs, RAG and automation into the software your business actually runs on.
Whichever fits the job. We design model-agnostic, so we use hosted models for quality and speed, or open-weight models on your own infrastructure for privacy and cost. We benchmark options against your data rather than defaulting to a favorite vendor.
By grounding and measuring. Retrieval ties answers to your data, output constraints limit what the model can say, and an evaluation harness tracks the real error rate. Where accuracy is critical, we keep a human in the loop and prefer deterministic logic over generation.
We design for it. Retrieval controls exactly what the model can see, sensitive fields stay out of prompts, and where compliance requires it we run open models on infrastructure you control. Privacy and data residency are constraints we plan for from the start.
Yes — we scope a narrow, high-value use case first, define its success metric, and build a measurable pilot. You see real numbers on accuracy, cost and time saved before scaling. We'd rather kill a weak use case early than sell you inference you don't need.
Yes. We work with product teams across the US, UK, Germany, Poland, the Netherlands and the Baltics, in English and remotely, with the process and communication a serious engineering partner is expected to bring.
Tell us the workflow you want to improve and we'll tell you, straight, whether AI is the right lever and what it would take to ship it. Talk to our engineers and get a grounded answer, not a pitch.
