Hey there, I'm Sascha Lang, founder of Tirvio.
After my Y Combinator startup, I ran a cold email agency. Here are some of the clients I worked with and what we delivered for them: 132 meetings for Secfix, 59 meetings in three months for Langdock (YC S23), 300+ product signups in a single month for Blosto. In total I've run outbound for more than 50 startups, including 11 YC-backed companies and several Sequoia and GV-funded teams, at over 100,000 sends per week on Smartlead.
Then I ran the same playbook on my 2nd startup. I co-founded a B2B SaaS business, used signal-based outbound as the only growth channel, and exited.
Tirvio is that engine, productized, for Seed to Series B B2B SaaS. The core idea: stop blasting templates. Combine AI research, deep scraping and timing signals to build value-first emails so every message is worth reading.
If you're a B2B SaaS team that wants pipeline without hiring SDRs or burning domains, let's talk.
