A conversation.
A structured next step.

The challenge
Launching an AI agent is easy. Keeping it running in production is not.
Most teams have a pilot, a clever prompt, one more tool. Nothing connects them, nobody measures them, and the day the agent gets something wrong, nobody knows why.
Boostia is an AI consultancy and agency: we don’t sell a tool, we build the system that makes your agents reliable, useful and auditable, and we hand it over to your team.
Without a harness
- Isolated pilots that don’t talk to each other
- No testing before going live
- Made-up answers, untraceable sources
- No human oversight
- Costs and errors discovered after the fact
With Boostia
- An orchestrator that coordinates the agents
- Evals and tests run before every deployment
- RAG: sourced answers, and a refusal when the answer is not in the knowledge base
- Human-in-the-loop on sensitive cases
- Traceability of every decision and every call
What we do
Five areas of expertise, one goal: real business impact.
A focused engagement or an outsourced AI team, from strategy to deployment. Each capability is scoped and configured for your project.
Knowledge AI
Put your documents to work: knowledge assistants, sourced answers, a refusal when the context is missing.
Agentic Automation
Connect your tools and workflows: autonomous agents and multi-agent systems, CRM & API, scoped permissions, approval steps.
AI Consulting
Find a practical starting point: use-case discovery, prioritisation by value, feasibility and risk, fractional Chief AI Officer.
Custom AI Development
Build around your business: custom applications, tests and guardrails, documentation and handover.
Team enablement
Practical training for your teams: you stay in control of the systems we build, with tests delivered alongside the code.
Our signature · Agentic Automation
A harness, not a pile of tools.
A central orchestrator coordinates specialised agents. Every exchange is put in context, evaluated and traced. Hover over or select an agent.
Selected agent
Orchestrator
It receives every request, picks the right agent, gives it the right context and tools, then checks the result before replying.
Our flagship solution · Calleat
Calleat: an agent from our harness, already at work.
A voice agent for restaurants: it handles incoming calls, understands the order in natural language, restates it, confirms it and passes it on. Built for a restaurant in Annecy. Proof that our approach works with real customers, on the phone, in the middle of service.

StatusPending
Simulated demo for illustration only: dishes, first names and opening hours are fictitious. It shows the real sequence: answer → understand → confirm → pass on.
Live RAG
Ask Calleat’s knowledge base a question.
Try a question a customer might ask. The answer comes only from the restaurant’s documents (fictitious here) and gives its source. A question outside the knowledge base gets an honest refusal, not an invented answer. Demo: local lexical search (BM25); in production: vector RAG (pgvector) and an LLM.
The answer will appear here with its source and relevance score.
Incoming calls, real-time voice
Picks up on every ring, even in the middle of service, and talks naturally with low latency.
Structured orders
Items, quantities, options, pickup time: restated, confirmed, then passed on without retyping.
Knowledge base (RAG)
Menu, opening hours, allergens, pickup: the agent answers from your documents and cites its source. Outside its scope, it does not guess.
Human-in-the-loop
Allergy, group booking, dispute: the agent transfers the call or schedules a callback. Every call is traced and transcribed.
Why now · voice AI news, October 2026
Voice agents have moved from gadget to infrastructure.
What is changing this year, with the sources so you can check for yourself.
A conversational AI market worth 17.97 bn USD in 2026
Forecast: 82.46 bn USD in 2034, around 21% annual growth (Fortune Business Insights, cited in the 2026 Famulor report).
Source: Famulor (FR) ↗ElevenLabs raises 500m USD and reaches an 11 bn USD valuation
Series D round led by Sequoia (February 2026): synthetic voice becomes a core layer of enterprise AI.
Source: VKTR ↗Nearly half of deployments are used for booking or scheduling
Bookings, confirmations, follow-ups: appointment management is the number one use of voice agents, far ahead of spectacular demos (Famulor, 2026).
Source: Famulor (FR) ↗Voice quality is the main barrier, ahead of cost
72% of decision-makers cite voice quality and fluency as the No. 1 obstacle, compared with 38% for price (Voices.com 2026, via Famulor). That is where the difference between a robot and an agent is decided.
Source: Famulor (FR) ↗Who it’s for
Startup, restaurant or SME: an entry point for everyone.
Fundraising is picking up again and AI is attracting most of the capital. Teams that raise funds have to deliver fast, with few people. That is exactly what Boostia offers.

Method
From idea to agent in production, in four steps.
Each step produces something you can see, test and measure.
- 01
Scope
Assessment, prioritised use cases, quantified success criteria before a line of code is written.
- 02
Prototype
A first agent connected to your real data, tested with your teams within a few weeks.
- 03
Harden
Evals, tests, guardrails, human oversight: the agent must fail visibly and survive mistakes.
- 04
Deploy & run
Go-live, observability, handover to your team, continuous improvement.
Trust
Agents you can put in front of a customer, an auditor or a recruiter.
Human handoff & approval steps
Sensitive cases (allergy, dispute, large amount) go to a person, with approval before any significant external action. The agent knows what it does not know.
Evals before every production release
Test suites, out-of-scope refusals, mutation tests: we hold our own deliverables to the rigour we sell.
Scoped permissions · AI Act & GDPR
Each agent acts only within the agreed scope. Transparency about the use of AI, data minimisation, rights of access and deletion.
Traceability
Transcripts, decisions and tool calls are logged. When something happens, you can explain why.
A practical starting point in 30 minutes.
Free assessment, no obligation: you leave with 3 prioritised use cases, whether or not you work with us.
