What Is hyperexponential?
hyperexponential builds hx Renew, a pricing platform for specialty and commercial insurers. In insurance, pricing is where the money is made or lost: actuaries build mathematical models that translate a risk's characteristics into a premium. Historically those models lived in fragile spreadsheets that took months to change and were painful to test against real outcomes. hx Renew reimagines that flow. It gives actuaries a modern environment to build a pricing model, deploy it to underwriters quickly, and then iterate on it as real quoting and loss data comes back — a continuous loop from data to decision and back to a sharper model. The problem it solves is speed and feedback: markets move, and a pricing model that takes half a year to update is always a step behind.
The company, hyperexponential, was founded in 2017 and is headquartered in London, with additional operations in Warsaw. It raised a 73-million-dollar Series B led by Battery Ventures with participation from Andreessen Horowitz (a16z) and existing investor Highland Europe. Established insurers write tens of billions of dollars of premium on hx Renew each year, including names such as Aviva, HDI, and Conduit Re — a scale that reflects how central pricing is to a carrier's results.
💡Key Concept
Pricing decision intelligence: Rather than treating a pricing model as a static formula, hx Renew treats it as a living decision that improves with feedback. Actuaries build and deploy a model, watch how it performs against real quotes and losses, and refine it — closing the loop between the data an insurer collects and the pricing decisions it makes. Faster iteration means pricing keeps pace with the market.

Core Capabilities
Rapid model building
hx Renew gives actuaries a purpose-built environment to construct pricing models far faster than the spreadsheet-and-code approach it replaces, shortening the time from an idea to a working model.
Deploy models to underwriters
Once built, a model can be pushed into the hands of underwriters through the platform, so the pricing logic actuaries design is the pricing logic actually used at the point of quoting — without a fragile hand-off.
Data-to-decision feedback loop
The platform captures how models perform against real quoting and loss experience and feeds that back to the actuarial team, so pricing sharpens continuously instead of being frozen between rare overhauls.
Governance and versioning
Because pricing models are mission-critical and regulated, hx Renew provides structure around how models are versioned, reviewed, and controlled, giving teams an auditable record rather than untracked spreadsheet edits.
Strengths
- Fast iteration: Building and updating models in a dedicated platform lets pricing keep pace with shifting markets instead of lagging by months.
- Closes the feedback loop: Real quoting and loss data flow back into models, so pricing improves continuously.
- Replaces fragile spreadsheets: A governed environment reduces the operational risk of critical pricing living in error-prone workbooks.
- Proven at premium scale: Major insurers price tens of billions of dollars of premium on the platform each year.
Limitations & Considerations
- Models still require actuarial validation. Faster iteration does not remove the need for qualified actuaries to validate assumptions and results; the human expert remains accountable for the pricing.
- Governance is non-negotiable. Insurance pricing is regulated, and speeding up model changes raises the stakes on review, documentation, and control to satisfy regulators and internal risk functions.
- Specialty and commercial focus. The platform targets specialty and commercial insurers; teams in very different lines should confirm fit before committing.
- Adoption and skills effort. Moving pricing off spreadsheets into a new platform is a change-management project requiring actuarial teams to learn new tools and workflows.
Best Use Cases
| Task | Why hyperexponential |
|---|---|
| Building specialty pricing models fast | Purpose-built environment replaces slow spreadsheet development |
| Keeping pricing current with the market | Data-to-decision loop lets actuaries iterate continuously |
| Getting models into underwriters' hands | Deploys actuarial pricing logic to the point of quoting |
| Controlling model risk | Provides versioning and governance over critical pricing models |
Getting Started
- Assess how your pricing models are built today and where spreadsheet fragility or slow iteration is hurting you.
- Engage hyperexponential to scope hx Renew for your specialty or commercial lines and your data sources.
- Migrate a priority pricing model onto the platform, keeping actuarial validation and governance central to the process.
- Use the feedback loop to iterate on that model against real results before expanding to more lines.
Key Takeaways
- hyperexponential makes hx Renew, a pricing decision-intelligence platform for specialty and commercial insurers.
- It lets actuaries build, deploy, and iterate pricing models quickly through a data-to-decision feedback loop, with tens of billions of dollars of premium priced on the platform annually.
- Founded in 2017 in London, it raised a 73-million-dollar Series B led by Battery Ventures with participation from a16z.
- The honest caveats are that models still need actuarial validation and that regulated pricing demands strong governance around fast iteration.
