Deep Dive
1 Overview
2 History
Stuart Lewtan is a serial entrepreneur with a track record of successful technology ventures. Before Zintro, he founded Lewtan Technologies, a 100+ person company serving 400+ institutional clients in the asset-backed securities industry, which was acquired by DMG Information in 2004 (later sold to Moody's in 2015). He also co-founded MicroE Systems (precision motion control, acquired by GSI Group) and Axsun Technologies (MEMS-based optical engines for telecom and medical imaging). Lewtan conceived Zintro around 2007 while serving as an executive-in-residence at a prominent Boston VC/PE firm, where he experienced firsthand the high costs and friction of traditional expert networks. He built Zintro as a fully self-service platform with no human intermediation. Over time, client demand led to the addition of full-service capabilities, creating the dual model that defines Zintro today.
3 Services in Detail
Self-Service Marketplace
Clients post project briefs to the platform; Zintro's algorithm anonymously matches them to relevant experts. Typically 5-12 experts respond within hours to a few days. Clients review profiles, select experts, and schedule calls independently. Complete price transparency with itemized expert fees and Zintro margins.
Full-Service Expert Calls
Traditional expert network service where Zintro's fulfillment team handles recruiting, screening, compliance, scheduling, transcription, and expert payment — comparable to GLG or AlphaSights but at 30-75% lower cost.
Surveys & Quantitative Research
Participant recruitment from the 1M+ expert database for quantitative studies and structured survey research.
AI-Moderated Interviews
Supporting clients using AI-driven interview moderation. Zintro reports that 82% of surveyed participants preferred AI-moderated over live interviews.
Custom Expert Recruiting
Tracking down niche experts outside the existing network for specialized requirements that the 1M+ database cannot fulfill.
Recruiting & Talent Placement
Facilitating full-time and part-time placements through the expert network, charging a 15% fee on first-year compensation.
4 AI & Platform
Zintro's proprietary matching algorithm understands semantic relationships between keywords — for example, a search for 'securitization specialists' automatically surfaces experts with 'MBS' or 'structured finance' in their profiles. Results are distilled into a single relevance coefficient for force-ranking experts. The algorithm can identify non-obvious expert matches that human recruiters might miss due to search habit bias, a capability Zintro calls 'alpha-generating discovery.' All initial client-expert interactions are anonymous until both parties agree to engage.
- ◆ Semantic matching algorithm understanding keyword relationships and synonyms
- ◆ Single-coefficient force-ranking of expert relevance
- ◆ Alpha-generating discovery surfacing non-obvious expert matches
- ◆ Anonymous client-expert communication until mutual agreement to engage
- ◆ AI-moderated interview support (82% participant preference over live interviews)
- ◆ Self-service project posting with automated expert notification
5 Compliance
Zintro provides standard compliance capabilities appropriate for its diverse client base spanning PE/VC, consulting, and corporate research. The self-service model places more compliance responsibility on the client, while the full-service option includes screening, NDA management, and conflict checks handled by Zintro's team.
- ● Standard MNPI guidelines with user-managed compliance for self-service
- ● Full compliance support (screening, NDAs, conflict checks) in full-service mode
- ● Platform-verified expert profiles with credential validation
- ● Anonymous interactions protect client identity until mutual engagement agreement
- ● Audit trail for all platform interactions
- ● NDA management and expert payment processing
Zintro's dual service model creates different compliance dynamics: self-service clients manage their own compliance workflows, while full-service clients receive traditional expert network compliance support. Clean regulatory record over 18+ years of operation.
6 Client Fit
Zintro is ideal for cost-conscious organizations that value price transparency and want control over their expert engagement process. The self-service model appeals to teams comfortable managing their own research, while the full-service option serves those who want traditional expert network support at lower cost. Premium institutional clients requiring the deepest compliance infrastructure may prefer established players.
- → Small and mid-size PE/VC firms conducting due diligence on a budget
- → Management consulting firms needing cost-effective expert access
- → Corporate strategy teams wanting self-service expert engagement
- → Market research firms recruiting survey participants and expert respondents
- → Startups and growth companies needing expert validation without premium pricing
