Customers pay for results (top 3 pre-vetted engineers delivered in 72 hours), not activity. ## Market Standing - **Valuation**: Not disclosed - **Key Metrics**: - Revenue: Not publicly available (likely pre-revenue or early traction) - Total Funding: Not publicly disclosed (company claims “no pitch decks”) - Team size: ~11 employees (LinkedIn) - Monthly web traffic: ~5,000 visits (thecohort.ai) - **Notable Investors/Partners**: None publicly mentioned - **Growth Signals**: - Launched publicly in late 2024 with a product built from first principles. - Recruiting for multiple senior remote roles across engineering, marketing, and data (indicates scaling). ## Competitive Advantages - **Speed**: Delivers top 3 candidates in under 72 hours vs. traditional 6-week processes. - **Full-stack AI agents**: Cover sourcing, prospecting, screening, and closing – fully automated. - **Outcome-based pricing**: Pay only for delivered, pre-vetted candidates; no subscription or per-activity fees. - **Built by operators**: Founders previously built and scaled hiring engines for high-growth tech companies (e.g., Egen), giving them firsthand insight into hiring pain points. - **Precision targeting**: AI scores candidates on skills, culture fit, and trajectory, learning from hiring team decisions. ## Strategic Focus - Continue expanding the SPEC agent platform and improving accuracy. - Scale the team to support increasing demand from startups. - Maintain a remote-first, global hiring approach (US, India, Australia, and remote-anywhere roles). ## Why Work Here - **Remote-first culture**: Most roles are fully remote (US or India), with flexible location options. - **AI-first engineering**: Opportunity to build production-grade AI systems and data pipelines from scratch. - **Tight-knit team**: Small (~11 people), flat structure, high ownership. - **Impact**: Shape a product that directly solves a critical pain point for startups. - **Values**: “No fluff. No pitch decks. Just results.” – fast-paced, execution-oriented environment. - **Tech stack**: Python, SQL, Google Cloud, AWS Lambda, Docker, PostgreSQL, Elasticsearch, GitHub Actions, microservices. ## Sources 1.
