General Partner
Y CombinatorCheck size: YC's current program deal is $500K for each accepted company: $125K for 7% on a post-money SAFE plus $375K on an uncapped MFN SAFE, together with a participation right. It is not Jon's personal check range.
Jon brings the paired lens of making a high-trust financial product accessible to consumers and then adapting its technology into an enterprise-grade platform for major institutions. He is relevant to founders who must earn user trust, handle regulation and sensitive data, deliver correct outcomes and translate a focused product into infrastructure that integrates with complex incumbents.
A painful high-trust problem, strong technical founders, clear user benefit, rigorous security and compliance, trustworthy recommendations or automation, excellent consumer UX, institutional-grade reliability, integration capability and a path from early adoption to repeatable distribution.
No personal pass list is public. His experience implies weak fit for regulated products that treat compliance as an afterthought, consumer finance without trust or economic benefit, enterprise platforms unable to meet security and integration needs, black-box advice without accountability and broad fintech claims with no initial wedge.
Apply through YC. Demonstrate the user or institutional workflow, trust failure in current products, regulatory perimeter, product and engineering insight, security, data permissions, accuracy, early usage and retention, distribution, integration plan and business model. If B2B2C, explain who buys, who uses and who bears risk.
Measure correctness, transparency, security, user control, recourse and the consequences of failure in a sensitive workflow.
Preserve user value while adding permissions, compliance, administration, integrations, reliability and support required by institutions.
Identify licenses, fiduciary or advisory obligations, data rules, disclosures, supervision and accountable entities before scaling.
Separate buyer, end user, beneficiary, data owner and risk bearer and align product incentives across all five.
