Business challenges we address
As insurance operations grow, speed, accuracy, and decision quality define profitability. Underwriting, claims handling, distribution, and compliance all depend on how well systems work together. We develop custom InsurTech software that improves execution across underwriting, claims, fraud defense, and policyholder experience — for faster decisions, stronger loss ratios, and an insurance environment built for scale.
Disconnected legacy core systems and ACORD bottlenecks
Our InsurTech solutions unify these environments through API architecture and semantic middleware. Legacy policy administration, ACORD flat files, broker feeds, and claims data are translated into a single, structured operational layer, so underwriters and claims teams work from one source of truth instead of re-keying data across siloed core systems.
Slow, manual underwriting and quote-to-bind
Our AI-driven underwriting workflows evaluate risk signals, third-party data, and policy rules in real time. This collapses quote-to-bind from days to minutes, raises straight-through processing rates, and lets underwriters focus their time on the complex, high-value risks that actually need human judgment.
Insurance fraud and deepfake claims defense
Our claims integrations include behavioral AI and automated fraud scoring. Claim patterns, image authenticity, document provenance, and ghost-broker signals are continuously evaluated, helping SIU teams flag AI-generated evidence and suspicious activity before payouts are approved.
Continuous, autonomous claims processing
AI claims control towers provide continuous monitoring of FNOL intake, third-party data, adjuster capacity, reserve movements, and regulatory deadlines. This architecture supports automated triage, straight-through settlement of simple claims, and more predictable performance across the claims lifecycle.
Custom InsurTech solutions we build
Autonomous underwriting and claims control
AI underwriting control towers
Control towers monitor submissions, third-party data, exposure limits, and portfolio appetite in real time. When a risk falls inside defined rules, the system can auto-quote, bind, or route the case to an underwriter with a full risk summary.
Digital twin of the risk portfolio
A digital twin creates a virtual model of your book using policy, exposure, and claims data. Teams can stress-test scenarios like a catastrophe event, rate change, or reinsurance shift before they affect live results.
Regulatory and NAIC compliance AI
Compliance pipelines process model decisions, rating factors, and adverse-action reasons, automatically generating audit-ready documentation aligned with the NAIC Model Bulletin on the use of AI in insurance.
Policy administration and distribution
Agentic quote-to-bind
AI agents process submissions, pull third-party data, apply rating rules, check appetite, and issue a bound policy with minimal manual work.
Policy administration software
Quoting, issuance, endorsements, renewals, billing, and reporting are centralized within one streamlined policy lifecycle.
Continuous underwriting
Underwriting combines telematics, IoT, and third-party data to reassess risk in real time rather than only at annual renewal.
Digital distribution and agent portals
Agent, broker, and direct-to-consumer portals handle quoting, document upload, e-signature, and policy servicing in a single flow.
Claims, documents, and fraud integrity
Predictive claims triage
Machine learning models score incoming claims by severity and complexity, fast-tracking simple claims and routing complex ones to the right adjuster.
Computer vision damage assessment
Computer vision evaluates photos and video of damage to estimate loss, detect inconsistencies, and support faster, more consistent claims decisions.
Deepfake and fraud detection
AI models verify image authenticity, document provenance, and claimant behavior to flag AI-generated evidence and organized fraud before payout.
Document intelligence for FNOL
Document understanding extracts structured data from ACORD forms, police reports, and medical records, removing manual intake from first notice of loss.
Policyholder experience and operational efficiency
Policyholder self-service
Policy details, payments, claims filing, and status tracking are handled in a single branded app or portal, reducing call-center load.
Pricing and premium optimization
Optimization systems continuously analyze loss experience, elasticity, and competitor rates to inform pricing decisions across the book.
Agent and adjuster activity monitoring
Monitoring tracks productivity, cycle times, leakage, and SLA compliance across underwriting and claims operations.

It's not just a tool; it's the compass that guides your business to the future.
Yury ShamreiCEOWe build an insurance system that improves itself
Insurance performance depends on how quickly operations turn data into decisions. Underwriting, claims handling, distribution, and pricing require systems that function as a single structure. We build insurance environments where policy administration, claims, third-party data, and operational workflows work as one decision layer — IoT, AI, and machine learning support live execution and help the system grow with your business.
IoT and telematics for usage-based insurance
Connected vehicles, homes, and wearables continuously generate the data that defines risk, pricing, and prevention. Our telematics solutions create a single environment across underwriting and claims, giving actuaries, underwriters, and leadership full visibility into how policyholders behave and how risk changes over time.
IoT development servicesArtificial intelligence and agentic workflows
Our AI solutions turn insurance operations into faster, more coordinated systems. AI works directly with policy administration and claims environments, processing live data and executing approved business logic within clearly defined rules. Your teams get faster decisions, stronger consistency, and fewer manual bottlenecks across daily operations.
AI developmentBig Data and ML
Our Big Data and machine learning solutions turn fragmented policy and claims data into a continuous optimization layer across the insurance lifecycle. Pricing, reserving, and portfolio management move into one continuous process, so results stay predictable, loss ratios improve, and capital allocation becomes significantly more precise.

Production-ready deployment roadmap
Replacing insurance infrastructure requires more than a standard software rollout. Underwriting must stay uninterrupted, claims must keep moving, and compliance must hold across every product and state.
Our deployment model is built for operational continuity. Performance is validated before cutover, ROI is proven before scale, and rollout happens in controlled stages without disrupting the business.
Phase 1 – Core system and API auditing
The first step is an audit of your operational environment – core policy administration, claims workflows, and critical integration points across the insurance lifecycle.
During this stage, we identify where manual work and system gaps create delays, increase leakage, and slow underwriting and claims. We also define baseline KPIs so every technical decision directly supports measurable business outcomes and loss-ratio improvement.
At the end of this phase, you receive:
- A system blueprint
- Integration architecture
- Rollout priorities
- A clear ROI model
Phase 2 – Shadow AI pilot
Before replacing operational workflows, the new system runs in parallel with your existing process. AI-driven underwriting and claims triage work alongside human teams while live operations continue without interruption. This lets us validate decision reliability and measure real impact under production conditions.
Leadership receives clear proof of cost savings and accuracy improvements before production cutover, along with go/no-go criteria for scaling the solution across lines of business.
Phase 3 – Compliance validation and phased rollout
We devote the third phase to validation against regulatory and audit requirements. Model decisions, adverse-action reasoning, and data lineage are tested to ensure the system holds up under examination and NAIC-aligned scrutiny. After validation, rollout moves in controlled stages across products, states, and teams.
Deployment includes:
- A controlled rollout
- Team enablement and education
- Post-launch operational support
Frequently asked questions
We never let a black-box model decide alone. We engineer a Dual-Engine Underwriting Architecture. Deterministic, auditable rules enforce eligibility, filed rates, and regulatory constraints, while machine learning scores risk within those boundaries. Every decision produces an explainable reason code and adverse-action documentation, aligned with the NAIC Model Bulletin, so compliance teams can defend it under examination.

Post-launch support
We recommend that you do not neglect post-release support. It includes monitoring, alerts, security patches, dependency updates, response to changes in third-party APIs, minor improvements, infrastructure maintenance (cloud, networks, storage), and SLA reporting. It's also valuable to get post-launch user training and development according to the roadmap.
Why insurers trust Nexterse LLC
ROI-first architecture
Every project starts with business economics. We define KPIs such as loss ratio, combined ratio, quote-to-bind time, straight-through processing rate, claims cycle time, and leakage before development begins. This allows leadership to see clear ROI, controlled TCO, and measurable business impact. 98% of our Clients are satisfied with our delivery quality, and 70% return with another project.
Legacy core to AI translation
Your partners and core systems still run on ACORD flat files and legacy policy administration. AI needs structured APIs. We build semantic middleware that converts legacy formats into structured JSON and routes them into production-ready business systems and vector databases. This makes decades of insurance infrastructure usable for automation, analytics, and AI without replacing your ecosystem.
Production-ready deployment approach
We use shadow pilots, parallel validation, and phased rollout before production cutover. AI underwriting runs alongside your underwriters first, claims triage is validated against historical outcomes, and automation is proven in live operations before it takes on more responsibility.
Enterprise-grade security and compliance
We use ISO 9001- and ISO 27001-aligned processes, role-based access control, encrypted data flows, audit trails, and a zero-trust API architecture. AI agents never have direct access to the core database. All sensitive actions move through controlled middleware, so policyholder data stays protected and regulatory risk is minimal.
