INSART runs two complementary delivery modes under one roof — a Startup Studio that ships fixed-scope fintech products in weeks, and an Enterprise practice that modernizes the systems financial platforms run on. Same engineers. Same fintech focus. Different gear.
Fixed scope, fixed price, real product. For founders who need traction, not slide decks.
Modernization, integration, and scale engineering for platforms 10K+ users depend on.
We've built the same fintech engineering capability into two delivery models — one tuned for speed and validation, one tuned for depth and scale. Pick the lane that matches where you are.
Each program has a fixed scope, a fixed price, and a fixed timeline. No scope creep, no hourly rates, no ambiguity. You know exactly what you'll have in your hand on the last day.
From idea to a working fintech product with real paying users. A focused proof of concept with payment flow, conversion analytics, and validation data — the fastest path from a hunch to evidence.
Validate new product or technology bets without risking your live platform. We build an isolated proof of concept outside your stack so your team can see what works before committing internal capacity.
Structured modernization for established software platforms. Reduce technical risk, modernize the highest-leverage components, and make your platform safe to evolve again — without committing to a full rewrite.
Get your startup growing again. We audit growth blockers and ship the landing pages, paywalls, and conversion flows that turn interest into paying users — in two months flat.
A predictable way to win new B2B fintech clients. Done-for-you outbound infrastructure, sequences, and meetings — pointed at the exact ICP that already knows your kind of product.
Test and build demand in new geographies before you commit local headcount. INSART runs targeting, localized messaging, and outbound end-to-end so expansion is guided by real buyer signal — not assumptions from the home market.
Every program above maps to a startup we’ve actually shipped — concept to working product, fixed scope, real users. Five recent ones, straight from insart.com.
London-based property lending marketplace. We turned a pitch deck into a working platform with KYC, e-wallet integration, and an investor dashboard — sprint-based, scope-locked, ready for real users.

Stripe-based subscriptions and one-time invoices for financial advisors. Built from a Project Charter to a beta-ready product with role-aware logic, webhooks, and tokenized payments — built to be evidence, not theater.

Rebuilt a thin companion app into a React Native field platform with conversational AI, geofencing, push, and predictive workflows. Six months from gap analysis to a mobile experience richer than the web one.

A diagnostic + fix on a paid SaaS onboarding flow. We found where activation broke, rebuilt the first-run experience, and turned the leak into a conversion engine — without rewriting the product.

How the Studio actually ships. The exact sequence behind the productized programs — discovery, scope-lock, and a 6-week build cadence that turns founder ambition into a product real users can touch.
Read the story →Whether we're shipping a $10K startup MVP or rewriting a piece of a 1,400-firm wealth platform, it's the same 80+ fintech engineers, the same delivery discipline, and the same 20+ years of focus on financial services. The mode changes — the people don't.
We build, modernize, and integrate the systems financial platforms run on — from legacy re-engineering to new product delivery and deep API integrations. Exclusive fintech focus. US-incorporated. 80+ engineers. SOC 2 in progress.
Full-stack fintech systems from the ground up — backend, frontend, mobile, APIs, and cloud architecture.
Re-engineering, refactoring, and migrating aging fintech systems to modern platforms — without stopping operations.
Connecting custodians, CRMs, payment processors, and banking APIs into coherent, reliable workflows.
Pipelines, analytics platforms, and reporting systems that turn operational data into business decisions.
Automating the manual, repetitive parts of fintech operations — document processing, classification, intelligent workflows.
CI/CD, cloud infrastructure, and QA automation so your team ships faster with fewer incidents.
End-to-end delivery — discovery, roadmap, team setup, sprint execution, and stakeholder reporting.
Not a generalist software firm. Every domain below is something we've built production systems in.
Portfolio platforms, advisor CRMs, custodian integrations, performance reporting, fee billing.
Payment processing, transaction orchestration, multi-rail connectivity, reconciliation, fraud.
Loan origination, underwriting automation, servicing platforms, borrower portals.
Core banking integrations, digital banking platforms, account management, treasury operations.
AML, KYC workflows, regulatory reporting, audit infrastructure, compliance monitoring.
Order management, trade processing, market data integrations, back-office automation.
Policy management, claims processing, underwriting systems, agent portals for insurers.
Aggregation, enrichment pipelines, financial data APIs, enterprise data warehouses.
Open banking connectivity, API gateways, consent management, PSD2/FDX compliance.
Not a generic service list — these are the actual fintech components we've built for enterprise clients.
Across wealth, payments, banking and nonprofit-tech, INSART has been the engineering partner behind platforms that financial institutions, advisors, and fundraisers depend on every day. A snapshot:
Plus AdvisorEngine, Snappy Kraken, Salsa Labs, Enmark, FutureBricks, ChalicePay, ZimpleMoney, Couplr.AI, Smart Grant Solutions, and 500+ fintech integrations across our partner catalog.
Built and scaled a wealth-management CRM platform serving 1,400+ advisory firms.
Long-term platform engineering for one of the largest nonprofit-tech companies.
INSART's contribution to our technology played a key role in the Junxure acquisition and in achieving Franklin Templeton Investments acquisition metrics.
One of the main reasons we trust INSART with our business is the process transparency the team has established. The amount of features and suggestions was just awesome.
It seems as if INSART was with us from the very beginning. The team invests the same effort in what we do as anyone at Salsa Labs. One of our best experiences with fintech solution providers.
Whether you're a founder shipping an MVP in eight weeks or a financial-services CTO modernising a 15-year-old platform, AI is no longer a side project. We design, build, and operate AI features as production systems — same engineering rigour as the rest of our work, integrated into the systems of record your business actually runs on.
Domain-aware assistants for advisors, ops teams, and end customers — wired into your CRM, ledger, and policy data with grounded retrieval and audit trails.
Smart onboarding platforms that read statements, IDs, and contracts; flag fraud patterns; and turn weeks of manual review into hours — with human-in-the-loop where compliance demands it.
Credit scoring, churn prediction, and risk forecasting models running on real customer data — built to be explainable, monitored in production, and retrained on a cadence your risk team can sign off on.
Retrieval-augmented systems over policy, regulation, and operational knowledge — so the right answer comes back with citations, not hallucinations. Multi-tenant, permissioned, and version-aware from day one.
The unsexy work that makes everything else possible: clean pipelines, unified identity layers, real-time event streams, and the warehouses your models and dashboards both pull from.
We build with AI ourselves — MCP servers, agent-driven test generation, AI code review, and prompt-aware CI. That's part of why we ship faster than the line item suggests.
Founders don't ship AI as a feature in 2026 — they ship products where AI is the product. We build those MVPs the same way we build any other one: fixed scope, fixed price, real users.
Established financial platforms can't bolt AI on the side — it has to live next to the data, the compliance trail, and the production runtime. That's the work we do every week.
Three from inside fintech where we live every day; three from the industrial side, where we proved the same engineering plays anywhere data, sensors, and decisions need to be wired together.
Document AI + LLMs that read statements, IDs and contracts, score risk patterns, and route to human review only when compliance demands it.

Twenty years inside financial services has shaped how the team thinks — about money, trust, compliance, and edge cases. That instinct travels well into adjacent domains.
