Slide Raises $25M Series A to Reshape Financial Infrastructure for Insurance Payments
June 24, 2025
byFenoms Startup Research
Slide, a U.S.-based fintech startup founded by Michael Fass, has secured $25 million in Series A funding to transform how insurance payments and premium financing are handled across the United States. The round was led by Base10 Partners, with participation from Outsiders Fund, Top Down Ventures, and other institutional investors.
This injection of capital positions Slide as one of the most aggressively funded startups in the insurance infrastructure space, building modern tools for payment orchestration, embedded financing, and real-time underwriting.
What Slide Is Solving
The U.S. insurance industry is a $1.4 trillion behemoth that still runs largely on outdated financial rails. Despite rapid digital transformation in sectors like banking, lending, and investing, insurance payments remain fragmented, manual, and opaque - creating friction for carriers, brokers, and consumers alike.
Slide is building an intelligent payment stack purpose-built for the insurance ecosystem. Instead of relying on legacy billing systems and delayed processing, Slide enables real-time payment flows, embedded premium financing, and flexible installment options - all backed by proprietary underwriting models.
Their platform empowers:
- Insurance carriers to reduce collection risk and increase payment completion rates
- Agents and brokers to offer smarter, more transparent financing options to customers
- Consumers to gain more flexibility and visibility into their insurance payment plans
Key Features of Slide’s Fintech Stack
Slide isn’t just building another payment gateway. It’s creating a vertically integrated infrastructure layer tailored for one of the most complex verticals in fintech - insurance.
Core innovations include:
- Embedded premium financing directly within policy workflows
- Dynamic underwriting models that adjust based on policyholder risk and payment behavior
- End-to-end billing orchestration across multiple channels (ACH, debit, credit, digital wallets)
- Regulatory-compliant disbursement tools for insurers and MGAs
- Real-time reconciliation between carrier systems, finance partners, and end-users
This full-stack approach gives Slide a defensible moat in a market historically underserved by modern fintech.
Why It Matters Now
Timing is everything - and Slide is hitting the market at a perfect inflection point.
As insurers increasingly adopt API-first architectures and digital distribution models, the need for real-time, configurable payment solutions is growing fast. Traditional payment processors can't handle the nuances of risk-adjusted financing, flexible billing windows, or regulatory compliance within the insurance sector.
A recent Accenture survey found that 83% of insurance CFOs believe that "modernizing billing and collections" is key to improving customer experience and reducing churn.
Meanwhile:
- Over $330 billion in insurance premiums were financed last year through third-party channels
- 52% of insurance policyholders report frustration with billing clarity and payment options
- Legacy payment processors lack domain-specific underwriting, creating risk and inefficiency for carriers
Slide is solving a pain point that has been ignored for too long - and investors are taking notice.
But here’s where it gets interesting - not just for Slide, but for every founder operating in a complex industry.
The real leverage isn’t in just modernizing workflows - it’s in owning the invisible logic beneath them.
Slide didn’t try to disrupt the insurance industry by offering another shiny dashboard. Instead, they burrowed into the unsexy backend - the billing flows, the compliance layers, the underwriting math - and made it programmable. That’s where real defensibility lives.
Founders often chase obvious pain points visible to end-users. But the magic happens when you build products for the people behind the curtain: the finance teams juggling spreadsheets, the legal departments navigating 50-state compliance, the actuaries running overnight scripts just to reconcile cash flow.
Want to build something hard to replace? Don’t just plug into the stack - reshape the way it thinks.
That’s what Slide is doing. It’s not just fintech - it’s financial architecture, rebuilt from first principles.
Market Outlook: Insurance + Fintech Is the Next Infrastructure Frontier
The convergence of fintech and insurance - often called "insurtech infrastructure" - is one of the fastest growing segments in financial services.
- The global insurtech market is projected to reach $165.4 billion by 2030, growing at a CAGR of 34.4%
- Embedded finance within insurance (e.g., BNPL for premiums, in-policy financing) is forecasted to reach $70B in transaction volume by 2028
- Regulatory support for alternative premium financing models is expanding across major U.S. states
- Traditional premium financing players like IPFS and First Insurance Funding control legacy rails but lack embedded capabilities
Slide is at the forefront of this transformation - bringing fintech agility to one of the most inert financial verticals.
What’s Next for Slide?
With $25 million in fresh capital, Slide is doubling down on growth and expansion. Their near-term roadmap includes:
- Expanding integrations with insurance carriers and MGAs
- Scaling premium financing operations across more U.S. states
- Hiring across engineering, risk, and go-to-market teams
- Launching APIs for third-party platforms to embed Slide’s financing stack
- Exploring partnerships with neobanks and insurtech marketplaces
Michael Fass and his team are betting big on a future where insurance payments are fast, flexible, and deeply embedded in policyholder experiences. If they succeed, they won’t just modernize a payment flow - they’ll redefine an entire vertical.
