Receipts, not testimonials

The same signal lit up weeks before these rounds.

Each of these showed the engineering-acceleration pattern in public before the round hit the press, recognizable, venture-scale, and auditable, not a name you take on faith. To count in the panel, the signal had to predate the event by at least 30 days.

Cursor · AI dev tools

Their engineers were shipping far more code, and more developers piled in, all in the open through 2024, ahead of the priced round.

→ $2.6B Series B · Thrive Capital

Supabase · Dev infrastructure

A steady climb in code shipped, plus a relentless week-after-week release rhythm, was the leading signal.

→ $80M Series C

Resend · Email infra

A public engineering buildout accelerated ahead of the Series A announcement.

→ $18M Series A · Sequoia

Plus ~70 more, Anthropic, Pinecone, Groq, Clerk, Linear, in the public panel behind the 219 startup-period observations across 55 startups. See the method and the full ledger →

The head start, visualized

Signal fires

Commit velocity surges. Contributors spike. Infra buildout begins, all public on GitHub.

21-47 days later

The round is announced. The press covers it. Your edge is gone.

The crowd arrives

Warm intros circulate. Allocation fills. The price has jumped. Everyone “knew it all along.”

The Sunday email lands you at the first marker: 3 to 7 weeks before the crowd even knows there's a round.

Built by The Data Nerd

I kept hearing about the great ones a week too late. So I stopped waiting for the intro.

I'm one person, people call me The Data Nerd. I'm an engineer who writes the occasional small angel cheque, not a fund, so I'm never racing you for a deal.

For ten years I wrote those cheques out of Athens, not San Francisco. No partner network, no demo-day badge, and honestly I'm useless in a room, I'd rather read a commit history than work a conference. So I heard about the good companies the same way you do: a week too late, after the round was full and the price had jumped. That part actually stung.

Then in 2024 I watched a small fintech team I almost emailed, three founders, one repo, no press, no warm intros circulating. Two weeks later their engineers were suddenly shipping far more: commit activity tripled, new contributors piled in, new infrastructure appeared out of nowhere. Three weeks after that, a $4M Series A led by a top-tier fund. Every clue had been sitting in the open on GitHub (the website where engineers keep their work) the whole time. I couldn't un-see it.

So I built a tool that reads that trail across 350+ startups every week and hands me the names quietly taking off, in plain words, no code. Now I send those names to you.

And yes, I'm just one nerd reading GitHub. That's the point: no committee, no spin, no agenda. The read is fully automated, it ships on a schedule, and the whole method is published on SSRN with an open dataset, so it never depends on me having a good week. The full origin story, the six parables, and the open methodology →

• What it watches: which company teams are suddenly building a lot more
• What you get: a name, what it does, and a simple reason it's taking off
• What you do: reach out early, while it's still quiet

Before you trust a stranger's email

Three flaws I have on purpose.

I didn't set out to start a movement. I noticed something true and felt I had to publish it. So here's the deal up front, the parts of me that'll annoy you, before you find them out the hard way.

I'm slow to reply.

Two reply batches a day, never inside the hour. No DMs. If you need a vendor on Slack at 11pm, I'm not him.

No calls until you've subscribed.

I'd rather write you a long, honest email than burn your hour on a discovery call you didn't need.

No face, no voice, no name.

You'll never see me on a podcast or a LinkedIn selfie. The handle is what lets me say true things about how deal-flow really works.

“Trust the math, not me.”

If this signal needed a charismatic founder to make it land, it wouldn't be a signal. That's why I stay anonymous: the methodology is the protagonist, and I'm just the one who writes it down. If I'm right, the data carries the argument, not my face.

Here's the deal between us: you don't read code, that's my job, not yours. You read people, markets, and timing. I read the commit history so you never have to borrow an engineer's afternoon to know who's real. You make the call and look early in front of your team; I stay behind the regression. If you'd rather run the analysis yourself, that's useful to know too, it probably means I'm the wrong nerd for your thesis, and I'd rather you find out now.

The one idea this all rests on

GitDealFlow isn't a better database. It's a different signal.

Databases and warm intros tell you a company is hot once it already is. Engineering activity tells you before. Believe that one thing, and every other way of sourcing is just waiting for the news to break.

Code is more honest than copy. The deck lags the code by 21 to 47 days, and that gap is your whole edge.

The old way

• You wait for the warm intro, and so does everyone else.
• PitchBook and Crunchbase list the round after it's announced.
• By the time it's “obvious,” the price has jumped and the allocation is gone.

The new opportunity

• You see how hard they're building, the work that happens before any announcement.
• You see acceleration 21 to 47 days before the round or the press.
• You're early by default, not by luck.

It's not an upgrade to your database. It's the signal that sits underneath it.

The 3 false beliefs that keep you late

If you keep hearing about deals a week too late, it's one of three things.

Every investor who comes to me believed at least one of these. Here's the belief, and the epiphany that changes it.

1

The Vehicle

“My network just isn't good enough.”

× The False Belief

“I don't have the partner network or the demo-day badge. The best deals go to insiders, and I'll never be one.”

✓ The Epiphany

The signal is public. You don't need a network to read what engineers are building out in the open. Engineering acceleration shows up on GitHub before it shows up in a partner's inbox, and 219 startup-period observations across 55 startups prove the lead time is real.

2

Internal Belief

“I can't read code. I'm not technical enough.”

× The False Belief

“To spot engineering acceleration I'd need to understand repos, commits, contributor graphs. I'm an investor, not a developer.”

✓ The Epiphany

That's my job, not yours. Every Sunday issue arrives with the sector, stage, and a plain-English note on why it's hot. You read people, markets, and timing. I read the commit history so you never have to borrow an engineer's afternoon.

3

External Belief

“Even if I spot it early, the big fund will take the allocation.”

× The False Belief

“A brand-name fund will outbid me anyway. The head start doesn't matter if I can't win the round.”

✓ The Epiphany

The whole point of a 21-47 day head start is that you reach the founder before there's a round to fight over. While they're still heads-down shipping, you're the one investor who noticed. That's when a founder takes the call, remembers your name, and saves you room.

Week 0

The tool flags the signal. You reach out while the founder still has time to talk.

Weeks 1-4

You build the relationship while you're the only investor in the room. No competition, no noise.

Round opens

You're already in. Better price, real allocation, no scramble against ten other term sheets.

Kill all three, and only one question remains: which of this Sunday's five names is in your lane?

Proof, not promises

I'd rather hand you the receipts than a wall of testimonials.

This is early and privacy-first, so you won't find a logo parade or paid quotes here. You get the thing most tools never show: the actual track record, public and auditable.

Who it's for

Built for investors who want to be early, not analytical.

Solo angels, scouts, and seed funds who source in specific sectors and want to reach founders while the round is still quiet. You don't read code, and you don't want to. You read people, markets, and timing, and you'd rather hand the engineering read to the nerd who does it for a living. This is built for you.

You care about asymmetric upside, but you don't want to spend nights digging through raw GitHub activity or another bloated VC database. You want the read done for you, and a clean reason you can repeat to your partners.

You want a signal worth acting on, explained in plain English, before the deal becomes obvious.

There's a name for that investor: the First Mover: early on the signal, not on luck. If that's you, this is who I built it for.

Where it works, and where it doesn't

The signal reads public engineering activity, so it's sharpest in dev tools, AI/ML, infrastructure, data, and open-source-leaning startups. Deep-stealth or fully closed-source companies show up late, or not at all. If that's your whole thesis, this isn't your edge, and I'd rather tell you now than waste your Sundays.

Where this takes you

Your next six months as the investor who's early on purpose.

Not a promise of returns, I can't make those and I won't. This is the habit you build, and where it usually leaves you. The rhythm is the whole relationship.

After you confirm

Five names land in your inbox the same day. You read them in 90 seconds, flag the one in your lane, and close the laptop. Your first early read, done before coffee.

Month 1

You've sent three “saw your commits” emails while everyone else was still waiting for the intro. Maybe none reply yet. That's fine, the reps are the point.

Month 3

Two founders now know you as the one who reached out before the round existed. That reputation compounds, every early email makes the next warm intro land easier.

Month 6 Obtener la lectura de ingeniería antes que los demás es simplemente cómo haces sourcing ahora, sin código, nunca. También me has visto equivocarme en algunas llamadas en público, que es exactamente por lo que confías en las que acierto.

Nada de eso te pide leer código, convertirte en un cuant, o confiar en mí por fe. Pide una sola cosa: confirma tu correo una vez, y los próximos cinco nombres son tuyos para leer antes de que los demás se despierten.

El movimiento, únete a los First Movers

"Creemos que la próxima generación de grandes inversiones se encontrará en los datos, no en las redes."

Nuestra misión: hacer visible el impulso de ingeniería para cada inversor, no solo para los que tienen las conexiones adecuadas. Un mundo donde el capital encuentra a los constructores más rápido es un mundo donde se construyen mejores productos.

Primero a la señal

Ves la curva de commits antes que el comunicado de prensa. Esa es toda la ventaja.

Independiente de la red

No se necesitan presentaciones. La señal es pública. Solo tienes que mirar.

Metodología honesta

Conjunto de datos abierto, documento abierto. Me equivoco en público. Ese es el punto.

"Los First Movers no esperan la introducción cálida. Leen el historial de commits. Estás a un domingo de ser uno de ellos."

La versión honesta de lo que está en juego

Dos futuros. Un correo de domingo. Tu elección.

Si no haces nada

Los próximos seis meses se parecen mucho a los últimos seis.

• ×Te enteras de las grandes rondas la semana después de que cierran: por la prensa, por Twitter, por las mismas personas que todos siguen.
• ×Los acuerdos donde podrías haber sido el primero van a alguien que contactó 21 días antes, mientras tú aún esperabas la introducción.
• ×Tu ritmo de sourcing es el mismo: bases de datos, introducciones cálidas, y esperar que alguien te avise antes de que la ronda se llene.
• ×Dentro de seis meses estás en la misma silla, leyendo los mismos boletines, a un domingo de cambiar eso: igual que hoy.

La única diferencia entre dentro de seis meses y hoy son 24 domingos en los que no recibiste los nombres.

Si te suscribes hoy

En seis meses, ser temprano es simplemente cómo haces sourcing.

• ✓El día que confirmas: cinco nombres llegan a tu bandeja de entrada. Los lees en 90 segundos, marcas uno en tu área, cierras el portátil.
• ✓Mes 1: Has enviado tres correos de "vi tus commits" mientras todos los demás esperaban la introducción.
• ✓Mes 3: Dos fundadores te conocen como el inversor que contactó antes de que la ronda existiera. Esa reputación se acumula.
• ✓Mes 6: Obtener la lectura de ingeniería antes que los demás es simplemente cómo haces sourcing ahora: sin código, sin bases de datos, sin esperas.

El costo de este futuro: una dirección de correo. El costo del otro: cada acuerdo del que te enteras tarde.

Esto no es un truco de página de ventas. No actuar también es una decisión: solo que resulta ser la que te mantiene donde estás. El correo de domingo es gratis. El único riesgo real es quedarte atrás.

La Señal gratuita de los domingos

Cinco startups acelerando silenciosamente en GitHub, en tu bandeja de entrada antes de la ronda.

Cada domingo te envío cinco nombres que la herramienta marcó esa semana, cada uno con una nota en lenguaje sencillo sobre por qué se está moviendo y el sector en el que está. Es la lectura temprana que de otro modo le pagarías a un analista para hacer a mano, o que armarías con herramientas de datos que cuestan miles al año.

Ejecutarlo cada semana me cuesta cómputo real, datos de GitHub, modelos, infraestructura. Yo cubro eso para que tú no lo hagas. Sin tarjeta ahora, sin tarjeta nunca.

Esto es exactamente lo que llega a tu bandeja de entrada, cada domingo

• 5 startups acelerando en GitHub esta semana, clasificadas, las que están despegando silenciosamente
• Una nota en lenguaje sencillo sobre por qué cada una se está moviendo: nunca lees una línea de código
• El sector y la etapa de cada una, para que solo dediques tiempo a tu área
• Una ventaja de 21 a 47 días: los nombres antes de la ronda o la prensa
• Léelo en 90 segundos, un clic para darte de baja, y conservas cada edición que recibiste

Un analista junior haciendo esta lectura a mano es una contratación de más de €60k. Las herramientas de datos que se acercan cuestan €5,000-€30,000 al año. Tú pagas nada: yo cubro el cómputo para que la lectura llegue a mil inversores que se lo cuentan a cinco amigos, en lugar de a cien que pueden justificar el gasto.
