A protection layer for every individual. To do so, we’ve designed real-time governance and compliance agents. These agents validate every action someone takes in their desktop environment against a set of rules and protect people from mistakes. We are: - Small and well-funded. We’ve raised $4M from world-class investors like Gradient Ventures, Lightspeed, The Legaltech Fund, Y Combinator, and Pear VC. We are currently a team of 4 https://www.linkedin.com/search/results/people/?currentCompany=%5B%2298801508%22%5D&origin=COMPANY_PAGE_CANNED_SEARCH&sid=jYv. We are hiring thoughtfully, with ~3 people in the next 6 months. - Intensely trustful + high ownership. We optimize for impact per person by requiring high ownership from each member of our team. We hire experts, ambitious problem solvers, generally unstoppable people, and we place large amounts of trust in them. We prefer short (or no) meetings, full autonomy, and individualized schedules. ## YOUR MISSION Over the next 12-18 months, you will be one of our core product builders. This means you will talk to clients, scope and design features, and implement from scratch. ## OUTCOMES - 0 → 1 roadmap delivery: You’ll need to own a section of our roadmap and ship them from 0 → 1. This includes the full cycle, from idea/client discovery to rollout. Feature outcomes are measured via adoption and direct client feedback. - Reliable, secure, accurate, and fast engineering: With the stakes that we’re working with, we need to get things correct. We’re building always-on software (e.g, 99.5% crash-free and secure-by-default). Our agents must be accurate (e.g, one of our features has 0.9 F1) and can’t add significant latency (e.g, another feature has <0.3s p95 inference time requirements). ## COMPETENCIES - Taste and product building experience (must have): You have to love building ‘tasteful’ products that customers love using. This typically means 0 → 1 experience alongside strong frontend/design/UI/UX understanding. - React + backend + engineering hygiene (must have): Strong TypeScript/React; hands-on backend experience (Node, Go, or Python). Good engineering hygiene (CI/CD, tests, reviews). - Deeply empathetic (must be): Both our team and our customers require empathetic and low-ego people. Some of our users’ careers depend on our product being ‘right’, so trusting and listening to them is our most important skill. - Independent and process building (must be): We don’t have a lot of structure. You’ll build a lot of processes and make standards by yourself, and everybody we hire after you will follow these. - Endpoint/inference experience (nice to have): Experience with browser extensions/device endpoints, and very fast/scalable inference would be useful for this role. ## LOGISTICS - Salary: 120-250k - Equity: 0.3-1% - Location: In-person in SF, and (optionally) occasional travel either for clients or for offsite. - Perks: Meals, housing/relocation, equipment, and benefits provided. - Work authorization: We can’t sponsor visas at this time. ## About Truth Systems ## Company Overview - **One-liner**: Truth Systems provides a programmatic AI governance agent that monitors and blocks non-compliant AI usage in real time across all vendors, primarily serving regulated industries like law firms. - **Entity Type**: Private (Seed stage) - **Headquarters**: San Francisco, California, United States - **Founded**: 2023 - **Founders**: Anh (Alex) Mac (CEO) and Nam Nguyen (COO) ## Core Business - **Primary industry/industries**: AI Governance, Compliance, Legal Technology, Cybersecurity - **Target customers**: B2B, Enterprise — specifically law firms (AmLaw 50/100), banks, and other regulated industries - **Mission or purpose statement**: "We are establishing the new standard for AI governance, building a future where every professional can innovate safely and confidently."
