Life Implodes During the Pivot: Co-founder Leaves, No Cash, Twins, Medical Bills
Nick recounts the lowest point: losing his co-founder, support network, and personal financial runway while trying to keep the company alive. At the same time, a high-risk twin pregnancy and uncovered medical costs forced a move abroad, creating extreme personal pressure alongside the startup’s uncertainty.
- •Co-founder departure and loss of confidence from most supporters
- •Near-zero personal cash while still needing to hire and build
- •High-risk twin pregnancy with U.S. insurance refusing coverage
- •$10K weekly medical bills and the risk of bankruptcy
- •Relocating to the UK and continuing to build through crisis
- 0:45 – 1:54
What Sphere Does: AI-Powered Indirect Tax Compliance for Global Companies
Nick defines Sphere and the specific wedge: indirect taxes like sales tax, VAT, and GST. Sphere helps internet businesses register, calculate tax at checkout, file returns, and remit payments globally, backed by a new Series A to expand the opportunity.
- •Sphere focuses on indirect tax (sales tax, VAT, GST)
- •Core workflow: registration → calculation → filing → remittance
- •Targets fast-growing, cross-border software/AI companies
- •Raised a $21M Series A led by Andreessen Horowitz
- •Funding used to double down on global expansion
- 1:54 – 3:22
From Finance to Edtech Marketplace: The First YC Company and Early Traction
Nick explains his finance background and why he left for entrepreneurship, building an edtech live-course marketplace after a disappointing MBA experience. The company entered YC, grew quickly, and reached meaningful GMV and ARR—setting up a difficult pivot decision later.
- •Nick’s background: PwC and Macquarie (finance/advisory)
- •Built an edtech marketplace for live courses taught by industry experts
- •Met co-founder through mutual connections in Australia
- •YC growth: ~$1.5M GMV with ~20% take rate
- •Reached roughly ~$300K ARR before pivoting
- 3:22 – 4:32
Why They Shut It Down: The False Assumption That Broke Scalability
Despite traction, the business model hinged on instructors producing high-quality course content themselves. In reality, content quality suffered and the team had to become deeply involved, turning it into a media-like business with poor scalability—plus a tough edtech market ceiling.
- •Assumed instructors could productize and self-create great courses
- •In practice, content quality required heavy hands-on involvement
- •Model drifted toward a services/media business
- •Edtech market dynamics made building a huge outcome unlikely
- •Decision: shut down rather than spend 10 years on a capped business
- 4:32 – 5:33
‘Pivot Hell’: Chasing What’s Hot and Why Thrashing Doesn’t Compound Learning
After shutting down the first company, Nick and his co-founder cycled through trendy ideas, especially around the early ChatGPT wave. Nick describes why this approach failed: they didn’t know the customers and each attempt reset progress, making iteration slow and conviction hard to build.
- •No clear next idea after shutting down the first startup
- •Tried AI agents for sales and AI-generated integrations
- •Entered markets they didn’t understand and lacked customer intimacy
- •Learnings didn’t compound; each idea restarted discovery from zero
- •Realization: stop chasing hype and anchor in domain expertise
- 5:33 – 9:26
Solo Reset: Focus on CFOs, Finance, and Surviving a Personal Crisis
Once the co-founder left, Nick narrowed to what he knew best—finance—and targeted CFOs specifically, which made learning and iteration compound. He also details the intense period of personal hardship and why he continued: proving resilience and having no other viable path.
- •Co-founder leaving removed the need to overlap interests
- •Strategy shift: focus only on finance and talk only to CFOs
- •Compounding insights replaced random experimentation
- •Personal hardship: high-risk twins, medical bills, relocation, charity housing
- •Motivation: prove doubters wrong and fight through a no-choice corner
- 9:26 – 10:29
Finding the Real Problem: Cross-Border Compliance Pain (Sales Tax/VAT/GST)
Nick connects the opportunity to lived pain from the prior marketplace business, where indirect tax issues are acute. He frames the broader thesis—helping businesses expand globally by removing compliance friction—and then narrows toward tax as the repeated pattern across customer conversations.
- •Prior company experienced sales tax/VAT/GST issues directly
- •Marketplaces owe tax on full GMV, not just their take rate
- •Broad thesis: remove cross-border compliance friction for global expansion
- •Systematic discovery revealed tax as a consistent, escalating problem
- •Identified gaps where incumbents handled international needs poorly
- 10:29 – 14:39
Methodical Customer Development: 60 Calls, Figma Prototypes, and LOIs
Nick outlines a structured three-stage approach: discovery calls, prototype feedback, and then selling. High-fidelity Figma demos enabled rapid iteration and helped secure LOIs, creating the conviction needed to commit to building.
- •Stage 1: 20 discovery calls with CFOs to map pain points
- •Stage 2: 20 calls using high-fidelity Figma prototypes; nightly iteration
- •Pattern matching showed international tax as the strongest wedge
- •Stage 3: 20 selling-focused calls to non-YC SaaS businesses
- •Outcome: 5 LOIs that validated willingness to buy
- 14:39 – 17:36
Selling Before Building: Landing the First 10 Contracts Off a Prototype
Without a technical co-founder, selling first wasn’t optional—Nick had to validate demand before engineering. Sphere secured its first 10 binding contracts from a Figma prototype, aided by true differentiation, speaking the CFO language, and a modular rollout that reduced risk.
- •Intentional strategy: sell before building due to limited engineering resources
- •Closed first 10 contracts from a Figma prototype (until credibility pushback)
- •Differentiation: international compliance vs. pen-and-paper workflows
- •CFO-centric selling: polish, rational ROI framing, and trust-building
- •Modular product enabled low-risk trials and land-and-expand adoption
- 17:36 – 18:54
Trust as the Product: Moving Upmarket, Security Proof, and Inbound Momentum
As Sphere moved upmarket, trust requirements intensified—security, references, and proof at scale became essential. Over time, Sphere’s differentiation in international functionality shifted the company from outbound-heavy sales to majority inbound demand.
- •Upmarket sales increases the burden of trust and procurement rigor
- •Trust signals: security posture, scale proof, references/referrals
- •Reference customers become a repeatable sales asset
- •GTM shift: from ~100% outbound to ~70% inbound
- •Core theme remains: trust is central even with a mature product
- 18:54 – 19:24
Why Global Tax Is Hard: 100+ Authority Integrations and End-to-End Automation
Nick explains that most vendors don’t truly automate global tax compliance—they outsource pieces to local advisors, creating manual work, delays, and higher costs. Sphere spent 18 months in stealth building deep integrations across many tax authorities to automate registration, calculation, and filing end-to-end.
- •Sphere built integrations into 100+ tax authorities across the U.S. and globally
- •Automates end-to-end: registration, calculation, filing, and remittance
- •Incumbents often outsource international work to local advisors
- •Outsourcing leads to poor UX, heavy back-and-forth, and 3–4x cost
- •Stealth period used to build defensible infrastructure and workflows
- 19:24 – 21:05
Building an AI-Native Tax Engine (TRAM) and Expanding Beyond Indirect Tax
Sphere’s second major differentiator is an AI-native tax engine that codifies and monitors tax law globally to apply correct tax treatment by product and jurisdiction. This foundation supports expansion into adjacent compliance areas like withholding tax, input tax, and tariffs—positioning Sphere as a broader revenue-based compliance platform.
- •AI-native tax engine monitors and codifies global tax law
- •Applies correct tax treatment to products across jurisdictions
- •Contrasts with ‘AI-washing’ limited to peripheral tasks
- •Adjacencies: withholding tax, input tax (expenses), tariffs
- •Vision: revenue-based cross-border compliance akin to Deel for payroll
- 21:05 – 21:52
Founder Advice: It’s a Mental Game—Persist, Focus on What You Know
Nick closes with guidance for founders stuck in pivot hell: resilience and persistence are the real differentiators. He emphasizes staying in the fight and narrowing to domains where you have genuine expertise and customer understanding.
- •Pivoting and persistence are primarily psychological challenges
- •Many people will rationalize quitting; endurance is rare
- •The tiny fraction who persist are disproportionately rewarded
- •Choose problem spaces where you have depth and credibility
- •Focus on what you know and what you’re good at to compound learning
