Swallow is a no-code financial pricing platform for insurers and financial teams. It lets actuaries build, test, and publish rating models as APIs, embedded forms, or AI chat and voice agents.
About Swallow
What Is Swallow
Swallow is a financial pricing platform built by Llow Group Ltd in London. It moves pricing logic out of spreadsheets and legacy systems so pricing teams can build, test, and publish models on their own. The company was founded in 2022 by Callum Rimmer, who previously co-founded the UK pay-by-mile insurer By Miles.
The core problem Swallow solves is slow release cycles. When pricing lives in Excel files and custom code, even a small change can take weeks and pull in developers who have other work. Swallow separates pricing from code, so business users edit the model while developers keep a stable system to integrate against.
The main limit is that Swallow is a business tool, not a consumer product, and it focuses on insurance pricing automation rather than general use. Pricing starts at £2,500 per month, and the platform is aimed at carriers, MGAs, and comparable firms rather than solo users. It also expects a real onboarding call before you get full access.
Getting Started
- Schedule a short setup call so the team configures the platform and APIs around your products.
- Import an existing model from Excel, generate a starting point with the AI agent, or build one from scratch on the no-code canvas.
- Connect data sources, then run scenario tests and what-if analysis to check behavior before launch.
- Set up approvals and version rules for your pricing team.
- Publish the model as an API, embeddable form, or conversational agent, and push changes live with one click.

Key features
No-Code Model Builder
Swallow gives pricing teams a drag-and-drop canvas for building rates, rules, and calculations. You can design logic visually and drop into custom code only where you need it. Once a model is ready, publishing it is a single click, and future edits go live the same way.
AI Agent for Model Creation
An AI agent called Herbie turns a written prompt or a set of documents into a tested, deployable pricing model. It also drafts governance reports for compliance, finance, and underwriting stakeholders. The point is to compress model creation from months into hours without losing the audit trail.
Automated Testing and Version Control
Every change triggers automated tests, so you can check accuracy and stability before anything reaches customers. Real-time previews show outputs as you adjust inputs. Each model version is logged, and you can roll back to an earlier one instantly if a change misfires.
Multi-Channel Distribution
A single model can be served through REST APIs, embeddable forms, chatbots, or voice AI agents. Because every channel reads the same model, customers get the same quote whether they use a form, ask a chatbot, or take a phone call. Swallow says it integrates with voice tools like ElevenLabs.
Governance and Auditability
Version history, role-based permissions, and audit logs track who changed what and when. The platform is ISO 27001 certified, and it lets teams export or delete data to meet GDPR requests. For AI channels, Swallow adds guardrails to cut down on hallucinated quotes.
SERFF Filing Indexing
For US carriers, Swallow indexes SERFF filings at scale, pulls out the rating logic, and turns it into an executable model. You can also monitor competitors' filings and run any risk through their reconstructed rating plans to see how your rates compare.
Pros and cons
Pros
- Pricing teams publish changes without a developer release cycle.
- One model serves APIs, forms, chat, and voice, keeping quotes consistent.
- Built-in versioning, approvals, and audit trails suit regulated industries.
- SERFF indexing gives US carriers a shortcut from filed rates to a live rater.
- Scales to millions of quotes per month, according to Swallow.
Cons
- No free tier. Pricing starts at £2,500 per month, which rules out small or individual users.
- Full access requires a scheduled onboarding call, so you can't just sign up and start.
- It's built around insurance and financial pricing, so teams outside those fields won't get much use from it.
- Many advanced claims come from the vendor's own materials, so independent benchmarks are limited.
