Ari’s ventures include two companies generating over $100 million in annual revenue, employing more than 1,000 people.\nhttps://www.sisu.site/\nThe Opportunity\nWe are seeking visionary and resourceful technologists to become CTO co-founders. If you are accepted into Sisu, you’ll collaborate with other exceptional founders, receive mentorship directly from Ari, and work toward building your own startup. This is a rare opportunity to start something meaningful with unparalleled guidance and resources.\nNote: This is not a traditional job-it’s an opportunity to be the technical co-founder of your own startup.\nAbout You (Technical Focus)\nWe are looking for top-tier engineers- i ndividuals who are prepared to go all in on building a disruptive venture from the ground up. You thrive in deeply technical environments that demand relentless ambition and unwavering determination. Sisu’s program is highly selective, admitting only 20 founders a year.\nDeep Technical Expertise: You excel in software architecture, systems design, product development, or related fields. Whether you’re a world-class engineer, a machine learning expert, or a cutting-edge product builder, your capabilities place you in a league of your own.\n\nEntrepreneurial Drive: You see opportunity where others see risk. You’re actively seeking the right partnership, network, and guidance to bring groundbreaking products to market.\n\nCollaborative Edge: While you’re fiercely self-driven, you understand the value of working alongside advisors, co-founders, and peers who challenge your thinking. You recognize the advantage of having direct access to a seasoned entrepreneur who’s scaled companies before.\n\nIf you see yourself in these qualities, we want to meet you. We’ll provide the tools, mentorship, and resources to build something truly extraordinary.\nApplication Process\nSisu admits founders on a rolling basis, selecting only 20 individuals per year across 10 startups.\nInitial Screening: A 30-minute phone/video interview with a talent principal.\n\nFounder Interview: A 30-minute phone/video interview with Ari Mir.\n\nWorking Sessions: Upon acceptance, you’ll join a 24 month program where you’ll work directly with Ari and the Sisu team.\n\nIf you’re ready to take the first step, we’d love to hear from you.","description_format":"text","description_chars":2810,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-09-19T01:54:06Z"}],"visa":[],"liveness":{"score":8,"band":"cold","label":"Long shot","p_open":1,"p_active":0.299,"p_room":0.28,"age_days":624,"expected_fill_days":30,"reasons":["conf:4","win:tail","crowd:"],"computed_at":"2026-11-12T10:38:37Z"},"pay":null,"html_url":"https://alion.io/job/sisu-cto-co-founder","json_url":"https://alion.io/job/sisu-cto-co-founder.json","meta":{"generated_at":"2026-11-12T20:37:23Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":43569,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-13T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":687255},"rest":"https://alion.io/mcp/rest/get_company?id=687255"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsisu-cto-co-founder"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fsisu-cto-co-founder"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fsisu-cto-co-founder"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/sisu-cto-co-founder\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsisu-cto-co-founder"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":1054905}},{"tool":"search_jobs","arguments":{"company":"sisu.site","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":1054905},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
