About OneGC

OneGC is building the legal function startups actually need, proactive and reactive, from inception through pre-IPO. The founder’s thesis comes from lived pain: his last company spent about $2.5M on big-law counsel over four and a half years, and he found big firms are great for tentpole moments (a big financing, M&A, major litigation) but a poor day-to-day partner, where an early-stage client is often paying $1,200/hour for a first- or second-year associate. OneGC gives companies always-on access to lawyers plus tooling that keeps them on the rails, similar to what Vanta did for SOC 2 or Rippling for hiring and firing, but for legal. The platform maps all 50 states’ employment laws (kept updated), generates custom legal workflows and documents largely via LLMs, monitors every client’s legal health (stale 409A, overdue board meetings, weak IP clauses, equity issued without board consent), and includes a full CLM with a rebuilt, licensed e-signature platform so a company can run its whole legal life in one place. Lawyers are there to review and handle what clients can’t self-serve. Traction is strong: since July they onboarded about 50 new clients in roughly 75 days and crossed $1M in revenue, with a demo-to-signing close rate over 50%. Growth is so fast that Evan has had to throttle it. They raised from well-known investors.

About This Role

This person owns the online presence, content, brand, and top-of-funnel. OneGC has done essentially nothing here yet (first-ever LinkedIn post was late last week; no socials, PR, content, advertising, outbound structure, or events program), so there are a lot of early wins. The goal is to drive qualified demos (from ~20-something a month to 50+), knowing the close rate is over 50%, so almost any reasonably qualified top of funnel converts.

The spike Evan wants is content generation, social media, and brand awareness, getting startups in front of other startups at a high clip, not partnership formation (they have people for that). Think a permanently-online growth marketer fluent across LinkedIn, Twitter/X, Reddit, Hacker News, and launch channels, who can run content, community, events, referral programs, SEO and especially AEO (getting OneGC’s content and data into the right places so startups find them first for legal). They set much of the creative direction themselves (with company support), own the voice, and manage the CRM (Monaco) and tracking. They get full access to the company and founders’ LinkedIn/Twitter and everyone’s network. Tone matters: OneGC sells legal services, so it has to stay mature and trustworthy (explicitly “not straight-up Corgi”), while still approachable and funny and plugged into the startup/tech zeitgeist. Companies Evan admires for this back-office-startup motion: early Ramp, Brex, Rho, Mercury to a degree, and Deel in its early days.

What You’ll Own

Top-of-funnel growth: driving qualified demos (toward 50+/month) across two motions (early-stage YC/Speedrun/a16z world, and a more upmarket motion)
Content generation and social media (LinkedIn, Twitter/X, Reddit, Hacker News, launches) and brand voice
Community and events, referral programs, SEO/AEO, and other creative top-of-funnel levers
Owning the CRM (Monaco), tracking conversion, and reporting on demos booked (the metric Evan cares about, not vanity metrics)

Requirements

A growth marketer who owns content, brand, and top-of-funnel end to end, scrappy and hands-on
Excellent at building a brand via socials and online; strong content creation
High agency and autonomous: gets things done, uses AI and tools, automates, figures out solutions, minimal management
Creative and big-thinking; can own creative direction from scratch
Gets the startup/tech zeitgeist and can hit a mature, trustworthy-but-approachable voice (not “Corgi”)
Comfortable owning a CRM and tracking conversion to demos booked

Signal

B2B (not B2C), ideally selling into startups; not enterprise-focused
People who did this well early at back-office-startup brands (Ramp, Brex, Rho, Mercury, early Deel)
~3 to 5 years out of college, has done this before

Who Will Thrive Here

A permanently-online growth marketer who wants to build a brand from the ground up in a wide-open space
A scrappy, autonomous operator who turns content and community into booked demos
Someone who can be a creative extension of the founder at events and online
A high-agency builder who wants room to grow
