Scope of Work
What your Grata team handles
Stealth Agents deploys Grata-fluent operators who build target lists to your thesis, research and verify companies, and enrich each record with the context originators need. A dedicated project manager owns sourcing quality and reports to your origination leadership, so your team runs more searches and outreach without adding local staff.
- Building Grata searches and target lists to a defined thesis
- Researching and verifying company size, ownership, and fit
- Enriching target records with contacts, notes, and context
- Screening candidates against your inclusion and exclusion criteria
- De-duplicating lists and standardizing company data
- Exporting sourced companies into your CRM cleanly
- Maintaining saved searches and refreshing lists on a cadence
- Preparing sourcing summaries and target-list reports
Why Teams Bring Us In
The bottlenecks inside Grata
Target-List Building
Translating an investment thesis into precise Grata searches and building clean target lists is time-consuming work that gates every sourcing campaign.
Company Research And Verification
Every candidate needs its size, ownership, and fit verified before outreach, and doing that research at volume pulls originators off the phones.
Data Enrichment Gaps
Raw target lists lack the contacts, notes, and context an originator needs, so someone has to enrich each record before it is usable.
Handoff To CRM
Getting sourced companies from Grata into your CRM cleanly, without duplicates or missing fields, is tedious and easy to get wrong.
The Managed Model
Output and oversight, without managing anyone
A dedicated project manager per client
One Stealth Agents project manager runs your team day to day, owning quality, coverage, and SLAs. Your operations leaders stay in control without managing individuals.
Scale the team, not the pricing model
Start with one Grata operator and scale to a team as your sourcing volume grows, a flat, per-operator model with no tiering. A dedicated Stealth Agents project manager runs the team, owns list-quality standards, and reports to your origination leadership.
Capabilities
What a managed team delivers
Thesis-Driven List Building
Build precise Grata searches and clean target lists to your investment thesis so every sourcing campaign starts from quality candidates.
Company Research And Verification
Verify size, ownership, and fit on each candidate so originators reach out to companies that actually match the mandate.
Data Enrichment
Enrich target records with contacts, notes, and context so each company is ready for outreach the moment it hits your list.
Criteria Screening
Screen candidates against your inclusion and exclusion rules so weak fits are filtered before they reach an originator.
Clean CRM Handoff
Export sourced companies into your CRM without duplicates or missing fields so origination flows straight into pipeline.
22-32 hrs
Reclaimed Per Week
List building and research returned to your origination team.
Dedicated PM
On Every Engagement
A Stealth Agents project manager owns list-quality standards, research SLAs, and coverage so you manage outcomes, not people.
Thesis-matched
Target Lists
Lists built and screened to your criteria so originators start from verified, outreach-ready candidates.
