I find SaaS founders who write checks, and get them on your calendar.
Operator-angels are the best money for a SaaS company and the hardest to reach. They do not sit in angel directories. They ignore generic pitch emails. They only respond to founder-to-founder outreach that speaks their language.
I was a founding partner at ULTRA.VC, an early-stage investor and venture studio. I sat on the investor side of this conversation and know what makes an operator-investor take the call. I also built the outbound engine that raised meeting booking rates 40%.

The target
Who I'd put in front of you
Operator-angels beat generic capital: they know SaaS metrics, they have felt churn, and they bring distribution and hiring help along with the check.
SaaS operator background
Built and exited or scaled a SaaS company as a founder or C-level operator. They evaluate your metrics with founder empathy and understand unit economics immediately.
Active check-writer
Has invested in software in the last 24 months. Confirmed on Crunchbase, AngelList, LinkedIn or in recent portfolio announcements.
Target check and stage
Check size and stage match your round. I pre-screen ticket sizes and stage preferences before initiating contact.
Thesis and domain fit
Thesis fit across your relevant vertical, business model or customer profile. They invest where they have real customer networks or unfair advantages to share.
Approach
How the pipeline gets built
Days 1 to 3
Align on your round, ideal investor profile, disqualifiers and the one-paragraph story. We distill your traction into a punchy message that an active founder can read in 20 seconds.
Sourcing
Build the list with Clay, Apollo, LinkedIn Sales Navigator and Crunchbase. Pull operators who have made angel investments, filter by SaaS background.
Vetting
Score each investor against the signals above. You only see names that pass.
Outreach
Personalized, founder-to-founder messages on LinkedIn and email. Warm intros through my own network where they exist. No blast campaigns.
Meetings
I handle the back-and-forth, schedule the call and send you a one-page brief on each investor before it.
Reporting
Weekly update with contacted, replied, qualified and booked, so you can see the funnel.
I'm comfortable owning the whole process, from first message to confirmed meeting. Your team only shows up to qualified calls.
