Most fintech tools weren’t built for your local auto shop. Affiniti is changing that. Founded in 2021 by Aaron Bai and Sahil Phadnis while they were students at UC Berkeley, the startup aims to become the financial brain for small and medium-sized businesses.

From Expenses to Intelligent Finance

Affiniti began by launching an expense management tool and a small business credit card in late 2024. These products weren’t designed for startups or tech companies, but for everyday businesses like HVAC companies, independent pharmacies, and auto dealerships. The goal was to help business owners manage spending, track expenses, and streamline reimbursements without relying on tools built for a different type of user.

The team has since expanded its ambition. Affiniti is building “AI CFO” agents; industry-specific financial tools that automate and manage banking, bill payments, sales analytics, cash flow insights, and more. Instead of being a generic assistant, each AI agent is tailored for a particular vertical, making financial intelligence more useful and accessible for busy operators.

Rapid Growth and Strong Investor Backing

In May 2025, Affiniti raised $17 million in a Series A round. This came only six months after an $11 million seed round, bringing its total funding to $28 million. Investors included SignalFire, Contrarian Thinking Capital, Sequel, Indicator Ventures, and several notable angels.

This new capital is being used to expand the platform’s features; building in banking services, deeper analytics, and integrations with systems like ERPs and point-of-sale tools. The speed of the company’s fundraising reflects both strong investor belief and a clear product-market fit in an underserved segment.

Going Deep with Industry Trust

Affiniti’s growth strategy isn’t just about tech. The founders have placed heavy emphasis on building credibility within the industries they serve. That includes partnering with trade groups for verticals like independent pharmacies. These partnerships help validate Affiniti’s offering and allow for bundled benefits, such as group purchasing discounts, which make the financial platform even more attractive.

“We want to be their full financial operating system over time, because we have the advantage of being the first fintech they’ve ever used.”

— Aaron Bai, Co-founder of Affiniti 

In just over a year, Affiniti has grown to 1,800 business customers and is processing $20 million in monthly transaction volume. It expects to cross $1 billion in total volume by the end of 2025.

Key takeaways for fintech startups

Here’s what fintech startups should take away from this:

• Focus on real-world business needs. Affiniti built tools for businesses often overlooked by fintechs
  
  
• Customize your product for the user, not just the sector. AI CFOs tailored to specific verticals offer more value than one-size-fits-all tools
  
  
• Strategic partnerships can unlock access and trust faster than broad marketing
  
  
• Fast, focused execution helped Affiniti raise two rounds in six months

Conclusion

Affiniti shows that there’s massive potential in building for the backbone of the economy. By combining tailored AI with deep industry insight, it is redefining what financial management looks like for small business.

If your fintech startup is looking to do the same, we can help you craft the strategy to get there. Let’s talk.

Chime launched in 2012 with a simple premise: what if people actually liked their bank? Founded by Chris Britt and Ryan King, Chime offered a mobile-first experience, no fees, and an unusually friendly tone. A breath of fresh air in a stale industry. But instead of getting a banking license, Chime cleverly partnered with existing chartered banks. It’s now one of the most recognized neobanks in the U.S., with over 7 million monthly active users and $1.67 billion in revenue reported in 2024.

“The trust levels that mainstream Americans have in banks is extremely low, and that was part of the opportunity that we pursued.”

-Chris Britt, Co-Founder and CEO of Chime (2023)

Of course, the road to becoming everyone’s “non-bank bank” wasn’t without its potholes. Let’s rewind through the highs, lows, and strategic pivots that shaped Chime’s journey.

Dependency on Banking Partners

In the early years, Chime leaned heavily on partners like The Bancorp Bank and Stride Bank to provide core banking services. This gave them a fast go-to-market route, but also meant they had limited control when things went wrong; which, unfortunately, they sometimes did.

How they navigated it: Chime strengthened relationships, invested in internal infrastructure, and quietly became more operationally resilient without breaking their “we’re not a bank” message.

Lesson for fintech startups: If you’re building on someone else’s rails, make sure your seatbelt (and your support agreements) are tight.

Service Outages and Customer Complaints

In October 2019, Chime’s customers woke up to locked accounts and frozen funds due to a major service outage. About 5 million users were affected, and the complaints piled up fast on social media.

How they handled it: Chime stepped up communications and worked to overhaul infrastructure and monitoring. Transparency improved. Trust slowly returned.

Lesson for fintech startups: Even with the best UX, backend cracks will show. And Twitter (or X, if you want) will absolutely notice.

Pivot to Financial Health

By 2020, Chime realized its “millennial banking” image was limiting. So, it leaned into financial health, launching features like early direct deposit, fee-free overdraft, and credit-building tools. This wasn’t just a rebrand; it was a mission shift.

Why it worked: These features hit real pain points, especially for low-income Americans. Chime moved from being “cool” to being useful.

Lesson for fintech startups: Branding helps, but solving real-life problems builds loyalty.

Regulatory Slap

In May 2024, the CFPB fined Chime $3.25 million and ordered $1.3 million in customer redress. Why? Account closures were delayed, and customers didn’t get their money back fast enough. Not a good look for a company built on trust.

What went wrong: A third-party vendor error led to the issue, but Chime took the reputational hit. They’ve since improved controls and compliance processes.

Lesson for fintech startups: Even when it’s “not your fault,” it’s still your problem. Regulation doesn’t care who wrote the code.

IPO Incoming

After years of speculation, Chime filed for an IPO in 2025, reporting 31% year-over-year revenue growth and aiming to position itself as the default choice for fee-free digital banking.

How they’re framing it: Steady user growth, deep engagement, and expanded offerings; including savings, credit, and possibly investments down the line.

Lesson for fintech startups: You don’t need to be a bank to go public like one, but you do need bank-level numbers.

Looking Ahead

Chime is still out to prove that a friendlier, cheaper, mobile-first approach to banking can win over the mainstream. With a successful IPO on the horizon and continued focus on financial health, it’s no longer just a clever idea – it’s a serious challenger to traditional banks.

Big changes are coming for Buy-Now, Pay-Later (BNPL) in the UK. Earlier this month, HM Treasury announced that the days of BNPL operating like the “wild west” are numbered. Starting next year, the sector will face proper regulation, bringing millions of shoppers stronger protections and giving fintechs a clearer rulebook to grow from.

Over 10 million people in the UK currently use BNPL products. Until now, they’ve had little in the way of safety nets if things went wrong; no affordability checks, no ombudsman support, and often confusing refund processes. That’s about to change.

What’s actually changing?

Under the new rules, BNPL providers will need to play by the same rules as other consumer credit firms. That includes:

• Upfront affordability checks to stop unaffordable borrowing
  
  
• Clearer information so users know exactly what they’re signing up for
  
  
• Faster access to refunds when purchases go wrong
  
  
• The right to complain to the Financial Ombudsman Service

This is all part of the government’s broader Plan for Change, aimed at modernising consumer finance and giving households more financial stability. According to Economic Secretary Emma Reynolds, the reforms are designed to protect working people while helping BNPL firms grow with confidence.

Out with the old, in with the flexible

The changes don’t stop at BNPL. The government is also reforming the 50-year-old Consumer Credit Act; replacing it with a more modern and flexible framework. Oversight will shift to the Financial Conduct Authority (FCA), cutting outdated red tape while keeping consumer protection front and center.

For fintech founders, this shift is big. It signals a move toward clearer rules, more regulatory certainty, and a level playing field for newer products like BNPL. The consultation on this kicked off in late 2024, and now the government is following through – with legislation already being laid in Parliament.

Key takeaways for fintech startups

Here’s what this regulatory shift means for founders and fintech teams working in or around BNPL:

• BNPL regulation is coming: Start preparing now if you offer or plan to offer split-payment products.
  
  
• Affordability checks will be non-negotiable: Creditworthiness tools or partnerships will be key.
  
  
• Stronger consumer protections = more trust: Faster refunds and formal complaint rights could boost user confidence and brand reputation.
  
  
• Regulatory clarity helps with growth: Investors and partners are more likely to back products that are FCA-compliant.
  
  
• The Consumer Credit Act overhaul matters: Fintechs working with lending, credit, or payment innovations should track these reforms closely; it could impact your entire roadmap.
  

These aren’t just rules to follow. They’re guardrails that could help the BNPL model mature and scale sustainably.
