What we believe
The founder should own growth but there are only 24 hours in a day.
Early buyers buy the founder: the conviction, the story and the person who will pick up the phone when something breaks. That is why founder-led sales is right. The limit is the calendar. Every hour spent building lists, writing sequences and chasing replies is an hour away from the product, the team and the raise.
The Codax Accelerator keeps you as the voice, the sender and the closer, and puts a team behind you that does everything else. We accelerate the founder. We do not replace the founder.
Same founder hours, more of the right buyers
Your extended growth team
Three engines around one founder
For 90 days, a senior team works inside your go-to-market. You set the direction and take the calls. We drive the volume, the tests and the follow-through.
01
Outbound
Your voice, at volume
- Target lists built and enriched against your ICP
- Buying signals scored so you reach the accounts that are ready now
- LinkedIn and email sequences from your own accounts, in your words
- Copy tested with you every round, more volume behind what books calls
02
Design partners
From first call to paid pilot
- A tight ICP, with stretch accounts named
- A design partner offer, terms and the proof each buyer needs to see
- A waitlist that keeps warm brands close and creates urgency
- LOIs and paid pilots tracked account by account
03
Advisory
From founders and growth leaders who have scaled
- Positioning and pricing for the first paying customers
- Your profile and story, ready for buyers who look you up
- Your first GTM hire, and when to make it
- The pipeline story for the next raise
Accelerate, not replace
This is not hiring an agency
Founders are told to avoid hired guns, and they are right to. Buyers at this stage want the founder, not a stranger with a script. So we never step in front of you. We stand behind you, and make every hour you give to growth go further.

The 90 days
How we dive in with you
Two weeks to assess and fix. From day 15 we build, test and scale at the same time, because a startup does not have the luxury to wait.
Assess and fix
Days 1 to 14
Your thesis, the buyer and what a design partner needs to see. Your profile and positioning fixed, the account list agreed, sending set up.
Build
Day 15 onwards
Target lists, buying signals and sequences across LinkedIn and email go live from your accounts, and keep growing.
Test
Day 15 onwards
Copy written with you is tested from the first send, judged on replies and calls booked. What books calls stays, the rest is cut.
Scale
Day 15 onwards
Volume moves behind what works the moment it works. Design partners signed, and a pipeline story ready for the next round.
Build, test and scale run together from day 15. A pipeline review at day 30, day 60 and day 90, account by account, moves the volume.
What we drive
What the 90 days are for

FAQ
Questions from founders
Is this an agency?
No. An agency takes the work away from you and runs it under its own playbook. The Codax Accelerator runs from your accounts, in your voice, with you on every sales call. We build and run the machine around you so the hours you put in reach more of the right buyers.
Who is the Codax Accelerator for?
Founders backed by Y Combinator or another accelerator who are selling to businesses and want the 90 days of the batch, or the 90 days after it, to produce paying design partners and a pipeline the next investors trust.
What does it cost?
$1,500 a month for the 90-day programme. That covers the extended growth team across outbound, design partners and advisory.
How much of my time does it take?
About an hour a week on priorities and copy, plus the sales calls you take. Outreach goes out under your name, so you sign off the message and we run the volume.
What is the follow-on investment?
Codax considers a follow-on investment in the next round raised by companies in the programme. Because we review your pipeline with you every month, the decision rests on numbers we have seen build, not on a pitch.
Is Codax affiliated with Y Combinator?
No. Codax is independent. Y Combinator and other accelerators are referenced as the audience we work with, and Codax is not affiliated with or endorsed by any of them.
Codax is independent and is not affiliated with or endorsed by Y Combinator or any accelerator. A follow-on investment is subject to Codax's review of the company and the round.
