Replace cold outreach with inbound project flow. Build your profile once, get matched to the right RFPs, and win work on quality.
Build Your Company Profile Once
Stop rebuilding your credentials from scratch for every prospect. Create one profile that showcases your team, domains, tools, and past work. Buyers find you before they even post an RFP.
- Highlight your domains, team size, languages, and tool certifications
- Add past project references and case studies that speak for themselves
- One profile that works across every buyer on the platform
Projects Come to You
When a buyer posts an RFP that fits your team, you get notified. No cold emails, no RFP databases, no chasing procurement contacts. The right projects find you based on what you actually do.
- Matched on your domains, tools, team capacity, and track record
- See scope, timeline, and budget before investing time in a proposal
- Filter by project type, size, and annotation platform
Compete on Quality, Not Just Price
Submit structured proposals that show your methodology, team composition, and relevant experience. Buyers evaluate you on fit and capability, not just who bids lowest.
- Proposals include your rate, timeline, approach, and team credentials
- Verified reviews from past projects build trust before the first call
- Stand out with real case studies, not just a pitch deck
