About Vertex Capital
Vertex Capital is a growth-stage investment firm backing B2B SaaS and fintech companies at Series A and B. We manage $420M across three funds and have backed 34 companies since 2018, including four that have gone public.
We believe that the best people in finance aren't always the ones with the most prestigious credentials — they're the ones who can build a model that actually reflects reality, spot the assumption that's hiding the risk, and present findings clearly enough that a board can act on them.
That's why we joined Xylomark. We wanted to see the work, not the pedigree. Every challenge we post is a real problem from our portfolio. The person who solves it best gets the job — regardless of where they went to school.

Members hired via Xylomark challenges
7 hires totalThe challenge was the best interview I've ever had. They gave me a real problem from a real portfolio company, reviewed my model without knowing my name, and offered me the job three days after the challenge closed. No awkward video interviews. No personality tests. Just the work.
I'd been applying to finance roles for 8 months with a non-traditional background. Most companies filtered me out before a human ever saw my work. Vertex's challenge was the first time my model was evaluated on its merits. Got an offer within two weeks.
What I appreciated most was that the blind review was real. When they revealed my submission was ranked #1, Rachel told me she'd been advocating for the model all week — she genuinely didn't know it was mine until the reveal. That tells you everything about how they operate.
