Reserv found the money hiding in the claims file

A tenant stops paying rent. The landlord has insurance. The claim ought to be small enough to understand and ordinary enough to settle. Yet ordinary claims have a habit of acquiring extraordinary amounts of paperwork. LEAP, an insurance intermediary serving residential landlords, encountered precisely this mismatch. In Accelerant’s account of its partnership with Reserv, frequent rent-related claims became a practical place to introduce automation. The interesting invention was a shorter journey through a familiar problem.

Reserv occupies a peculiar position in insurance. It is a third-party administrator, or TPA: an organization hired to handle claims for someone else. Its customers include carriers, managing general agents, corporate captives and brokers. The policyholder meets the service when something has gone wrong. The insurer meets the bill, the file and, eventually, the lessons.

01A customer before a company

The origin contains a detail aspiring founders should linger over. Runyon Design, which incubated Reserv with Bain Capital Ventures and Altai Ventures, says it arranged a three-year customer contract with Accelerant. Demand was waiting before the machinery was finished. Runyon also says the first claim was processed within 150 days of launch. Insurance, famously suspicious of novelty, had supplied an actual customer.

CJ Przybyl and Martha Dreiling founded Reserv in 2022. Przybyl had previously co-founded Snapsheet, bringing experience at the junction of claims and technology. Today he is CEO; Dreiling is president. Their company’s proposition bundles experienced claims professionals with software designed around their work. A buyer gets people to handle the problem and tools that make the resulting information easier to inspect.

That puts Reserv between familiar alternatives: an established outsourced administrator, a carrier’s internal claims department, and a software purchase that leaves the carrier running the operation. Newer TPAs such as Elysian and ClaimSorted occupy related territory. Owning an operating claims business gives Reserv somewhere to test what its engineers build.

02The price of moving a file

Consider the obstacle before any impressive demonstration: getting the old claims out of the old system. In June 2025, Reserv described automated rollover technology that ingests legacy records, maps them to its platform, structures emails and file notes, and reconciles financials. The company claimed migration times could fall from more than nine months to under two weeks. That is a vendor claim, rather than a promise for every portfolio, but it identifies the right nuisance.

A better workflow is difficult to buy if switching to it means a prolonged excavation. Reserv made that excavation part of the product. Its Glance platform, described in the May 2026 funding announcement, brings historical and open claims into a centralized database and lets clients vary the amount of automation. Simpler cases and complicated cases can receive different treatment.

The financing followed the work. An $8 million seed round came in 2022, then a $20 million Series A in 2023. Series B brought $25 million in June 2025 and a further $16 million that September, led by QBE Ventures. In May 2026, KKR led a $125 million Series C. The funding measures investor commitment; it does not establish what a customer saves.

03A claims file with a second job

Settling a claim produces information as well as a payment. The information often arrives in forms that resist neat counting: a call, an email, a note about the circumstances of an accident. Reserv’s analytics and reporting tools make those records useful to claims leaders and underwriting teams. Accenture’s 2025 investment brought a collaboration focused on integration and configuration for carriers with large, complicated legacy datasets.

In May 2026, Dreiling described a batch analysis that compared claim-file details with a client’s underwriting guidelines. She also offered a wonderfully concrete question: how many accidents involved left-hand turns? If a portfolio contains that pattern, it might change risk management or underwriting. The distinction matters. A claim file records what happened; a collection of readable files can suggest what to do next.

Reserv reported nearly 200 customers and $100 million in annual recurring revenue in its Series C announcement. ARR describes the recurring revenue run rate, rather than audited annual sales. Those figures suggest adoption. They do not, by themselves, tell us whether every claim closed faster or every underwriting decision improved.

04The technology gets its own door

For years, accessing Reserv’s technology meant outsourcing claims to Reserv. Dreiling’s AiDE announcement acknowledged that arrangement could never suit every carrier. AiDE opens another route: organizations retain their own claims operations and use the technology. Przybyl has described sharing those tools as part of the original intention, accelerated by generative AI.

The commercial detail is unusually legible. AiDE advertises compute cost plus 10%, with no seat or license fees. Its website gives an indicative $3 for ingesting and structuring a bordereaux report, the insurance industry’s periodic listing of business or claims. Pricing varies by task and volume. That figure belongs to a specific data task; it is not a price for settling a claim.

The offering includes intake, data extraction, subrogation detection, file-quality checks and portfolio analysis. Carriers retain ownership of their data, with no grant-back to Reserv. They and their integration partners can build workflows around the models. Buying this route consequently requires a team capable of turning the technology into working processes.

05A lesson in changing habits

By May 2026, Dreiling said Reserv had deployed 15 to 20 tailored AI agents. The harder challenge had become retraining people. Technology can draft the email; someone still needs to trust, check and use it. Reserv’s careers page emphasizes solving underlying problems, customer focus and remote work, but culture acquires substance when professionals change how they spend Tuesday.

There are limits to the promise. Dreiling said heavily litigated claims still have long tails. Reserv’s model offers more room to improve the routine journey between intake and resolution. The lessons worth borrowing are practical: secure operating demand, make migration manageable, and give the people doing the work a voice in development. Start with the landlord’s paperwork. Let the grand theory earn its keep.
