It's everything around it, and that's what takes the most time. In-house, your team solves - Contract models, pick them and migrate when better ones come out - The agent's orchestration, memory and tools - Connect and maintain each customer channel - An inbox and a CRM for the advisors - Encryption, permissions, traceability and approvals - Measure and evaluate what the agent answers And then, maintaining all of it when something changes. With Shimli, from day one I need a collections agent on WhatsApp connected to our core, with human approval for exceptions. - The agent is built by conversation, in under 10 minutes - FusionAI picks and updates the models for you - Eight channels, omnichannel inbox and CRM included - Encryption, per-client isolation, roles, human approval and traceability - REST API with an OpenAPI spec and MCP to extend it Your technical team focuses on what's specific to your business. ### The comparison, point by point Building in-house makes sense in some cases. The table shows what's left on each side. | Criterion | Build in-house your own development | Shimli all-in-one platform | | --- | --- | --- | | Time to production | 8 months on average from prototype to production, per Gartner | First agent in under 10 minutes | | Team required | AI, development and security engineers | The operations team, without code | | AI models | Contracts with each provider; pick, test and migrate | FusionAI picks them and adopts better ones without you changing anything | | Channels and CRM | Integrated or built separately | Eight channels, official WhatsApp and omnichannel CRM included | | Security and traceability | Designed and audited from scratch | Encryption, per-client isolation, roles, human approval and a record of every decision | | Control and extension | Full over every piece | Limits and policies you set, plus REST API and MCP to extend | | Cost | Team salaries, infrastructure and model usage | Monthly plan with every feature, plus AI usage | All of the above is in the $139 monthly plan, with AI usage in blocks of $49 per 2,450 queries. No implementation cost.

Can my technical team extend Shimli? – Yes. Shimli has a REST API with an OpenAPI 3.1 specification and supports MCP, so your team can connect in-house systems, build tools for the agents and integrate it with what it has already built. The documentation is at docs.shimli.app. Where does my data stay? + Data travels and is stored encrypted, each client operates in an isolated space and access is controlled by roles. Only stable, tested models run in production. Can I start with a pilot? + Yes. The usual path is to start with a contained process, measure it in the first weeks and connect the rest of the systems progressively via API.
