Outbound for YC founders — from zero to first $100K ARR.
You are pre-PMF. The batch ends in weeks, not quarters. To validate an ICP hypothesis you need to be in front of 30-60 buyers a week — and the engineering hours that go into the infrastructure are hours you are not spending on the product or the close.
Time is the binding constraint. Everything below is sequenced for that constraint.
Most YC B2B founders lose two to four weeks of the batch to the same predictable failure mode — the founder sends cold outbound from founder@yourstartup.com, the corporate domain reputation craters, transactional mail stops landing, and the team spends a week debugging instead of selling. The chapters below are the version of this discipline that exists before that mistake. Read the reading path first if you are starting from zero; jump into the cluster references if you are debugging a specific layer.
What to read first.
- 01Curated reading pathThe pre-seed reading path — standing up outbound from zero
The full sequenced read for batch founders. Ten chapters in order, from ICP hypothesis to a sending estate that lands in primary in four weeks.
→ - 02ICPClosed-won deconstruction — finding the first hypothesis
Even with 3-5 friendly logos, the attribute extraction surfaces the first ICP hypothesis. You need this before you write a single email.
→ - 03Design partnersWhen the design partner motion fits
If you are pre-PMF and B2B SaaS, this is the highest-leverage GTM motion you can run inside the batch. The case for choosing it over cold outbound straight away.
→ - 04Design partnersThe 30-to-3 recruitment funnel
Recruitment math that selects for actual ICP fit, not the first three founders willing to take a meeting. Includes the YC-batch leverage pattern (Bookface, batch Slack) at 3-5x cold-outbound conversion.
→ - 05Email infrastructureCold email — the complete setup reference
Fourteen chapters of email infrastructure. Skim once, then deep-read SPF/DKIM/DMARC, subdomain architecture, and warmup. The week you skip this is the week your founder domain gets blocklisted.
→ - 06CopyWhat makes cold copy good — the four principles
Good vs bad examples annotated. The four principles you cannot deviate from. Read before you write the first sequence, not after the first batch underperforms.
→ - 07ConferencesICP velocity testing at conferences
If a relevant industry conference falls inside the next 60 days, this compresses eight weeks of cold-outbound ICP learning into three days. Highest-density signal you can buy.

What we do for YC founders.
An engineer in your Slack who runs the upstream.
Domains, DNS, authentication, warmup, sequencing, reply routing — all of it operated end-to-end. You stay on the sales motion (discovery calls, design partner conversations, close cycles). We stay on everything that gets the prospect to the call.
YC-batch pricing and timing.
We move at batch pace. A typical engagement starts producing booked meetings inside three weeks — the same window you need to validate or kill the ICP hypothesis before Demo Day. Discounted scope for batch founders. Ask.
Built around the design partner motion when it fits.
Pre-PMF B2B usually wants design partners, not cold outbound at volume. We structure the program (recruitment, agreements, conversion math) and run the upstream sourcing for it. Cold outbound only when the motion has stabilized.
Case in production.
32 design partners reached in 3 weeks. 6 paid pilots in 90 days.
Two-founder fintech company, mid-batch. Started with a working prototype and a 40-account ICP hypothesis from a previous role. No sending infrastructure, no copy, no list. We provisioned domains and inboxes during week one, ran a 24-inbox warmup runway for three weeks while building the prospect graph, and launched into the validated list as warmup closed. First booked meeting day 19; 32 design partner conversations across weeks 3-6; 6 of those advanced to paid pilots inside 90 days.
The founders spent the same period heads-down on product and discovery calls. Total engineering hours sunk into infrastructure by the founding team: under five.
We can be running by next week. You stay on the sales motion.
Book a free 30-minute audit and we will tell you what the cheapest path to 30-60 conversations a week looks like for your specific ICP. If it is design partners, we run the program. If it is cold outbound, we run the upstream. If it is conferences, we plan the conference. YC-batch pricing available — ask on the call.
