Spencer Potesta

Psychotherapist, Company Builder, Author | Founder of Potesta Holdings Corporation & Social Capital Foundation

My background is in clinical and organizational psychology, dedicating time to psychotherapy for patients with severe anxiety and trauma disorders, while building and partnering with organizations in organizational psychology. The tools I use in therapy mirror those that help executives and organizations excel.

In psychotherapy, I run a private practice as a double-board certified psychotherapist in Illinois, offering specialized, evidence-based care for severe anxiety (like OCD) and trauma disorders (including dissociation). I dedicate a select few days per week to this transformative, client-centered work.

As CEO of Midsommer.org, I address clinical pain points—like limited access, high costs, and fragmentation—leading a pioneering mental health organization. We build a clinician-led holistic care model, revolutionizing psychotherapy with self-managing teams, comprehensive services, and ethical, insurance-based practices for affordability across states and specialties. We empower ethical clinicians to own teams as directors and co-owners (typically 10-12 grouped by region/specialty), creating sustainable foundations, better business outcomes, higher clinician satisfaction through collaboration, and dedicated client care. Achieved via aligned incentives and lock-step partnerships—not franchising—this forms a constellation of high-powered, human-centered teams. This bridges my passions of organizational psychology & psychotherapy, empowering resilience and impact for clinicians and clients.

In organizational psychology, I operate Social Capital Holdings, consulting Fortune 500/1000 firms on efficiency and performance. Now, I focus on engaged partnerships in businesses like Midsommer and others, strengthening systems, leadership, and operations.

While devoting time to psychotherapy a few days weekly and advancing ventures, my deepest passion is Social Capital Foundation. As President of this 501(c)(3) healthcare endowment, I tackle generational health needs, leveraging my success to innovate solutions benefiting practitioners and clients. We streamline operations to keep 100% of donations intact, supporting healthcare individuals and organizations.

Proud of you Carly and very excited for the journey!

I’m excited to share a meaningful milestone in my work. ✨

After two and a half years of running my solo private practice, I’m expanding into a group practice (name still in processing) dedicated to delivering high-quality, evidence-based care for OCD & anxiety across the Capital Region and greater Upstate New York.

I’m profoundly grateful for the opportunity to support this community — to offer resources, education, and specialized treatment in an area that has long been under-resourced for OCD and anxiety care. 🌿 

This next chapter is about deepening that mission: expanding access, building a strong clinical community, and bringing even more hope and expertise to those who need it most.

And with that, we’re hiring! 
 If you’re passionate about evidence-based treatment, collaborative clinical culture, and helping individuals reclaim their lives from OCD and anxiety, I’d love to connect. 

All key details are in the graphic, please reach out with any questions or interest!

Gemini 3 was just released! There was a lot of hype and rumors but I was not expecting Google to 2x the previous best score on ARC-AGI 2 (historically one of the toughest benchmarks out there)

Here's a bit more context on why this is a big deal:

ARC-AGI-2 is designed to stress test the efficiency and capability of AI reasoning systems, and provide useful signal towards AGI.

Pure LLMs score 0%

AI reasoning systems score only single-digit percentages (until recently)

Google's Gemini 3 just scored 45%, more than doubling the previous best of ~18% (from OpenAI's Pro model)

For all the "LLMs are plateauing" "New models aren't getting better", feels like progress is only accelerating.

Wow Google is on FIRE this week. They just released a major update to NotebookLM and the new slide functionality is incredible!

Turn your sources into a detailed deck for reading OR a set of presentation-ready slides. These are fully customizable too so you can easily control the look, feel and content.

Check out this presentation it made from one of my sources. 

It took two minutes and for educational purposes I'm posting the version it created with zero edits.

What do you think? Does it look like slop or is AI finally getting good enough to handle building out decks?

Harnesses are the new application layer for AI.

Just recently Poetiq became the first team to surpass the 50% accuracy barrier on ARC‑AGI‑2 and they did it by building a Harness for Gemini 3. 

They used the exact same LLM, all they did was update the scaffolding and steps the model takes to solve the problem set. 

This refinement (which they open sourced) improved performance on ARC-AGI-2 from baseline 31%, $0.81/task up to 54%, $31/task.

That's a HUGE jump in performance and efficiency just from providing better scaffolding. 

I've been really excited about the opportunity to build scaffolding around existing models so it was cool to see a team execute on this opportunity so effectively. 

A harness I've been experimenting with for a while is one to help make AI writing sound more natural, check out the video below for a full overview and intro to harnesses and how you can make your own using tools like OpenRouter, Inc.

Starting to wonder what interviews will look like in 12 months.

Poetiq scored higher than Google on ARC-AGI II and they did it using Google's own model

Google solved these visual puzzles with Gemini 3's unmodified test-time reasoning (costing $77 per problem)

Poetiq beat them (54% vs 45% accuracy) by building a better harness around Gemini 3 that scored higher but was also cheaper at $30/task

They added intentional scaffolding for the LLM to write a Python script to solve the grid instead of predicting the answer textually. 

Since the output is code, it's verifiable. 

The system runs the generated script against training examples, catches bugs, and lets the model fix its own code locally before committing to a final answer.

The exciting part is that harnesses like these are generalizable. Methods that work to improve Gemini 3 performance on ARC AGI can be applied in other domains. 

This is the new frontier.

Poetiq's Approach

OpenAI just dropped a 20 page guide on "Building an AI-native
engineering team". 

It's worth reading the full thing, but I've also been really loving using the new Google image model to create visual summaries of articles to keep for future reference.

Here's an example output based on the full 20 page guide:
