The company holds more than 40 patents and American Tower is evaluating its panels for its US tower sites.

How much funding has Swift Solar raised?

Does Joel Jean work with an executive coach?

The interview

From the conversation

Why did you start looking for a coach?

As we're moving from R&D into production, there's definitely a lot of personal changes that I've had to painfully make. To make Swift realize its full potential, I need to grow into a manufacturing CEO, not a technology development CEO.

What had stopped you before?

I started thinking about getting a coach many years ago. One of the things that held me back was the activation barrier of finding a coach, and Titan is reducing that to near zero.

What do you bring to the sessions?

We meet weekly and we just talk through a number of topics that are on my mind, fundraising, a pitch deck, a customer challenge, pricing strategy, a management challenge, a personnel issue, a hiring question. Anything is on the table.

What do you value most in him?

What I really appreciate about my coach is that he's able to be super hard-ass, really, and tell me the straight truth the way he sees it.

What has changed since?

Since starting coaching, I've been able to make decisions with more confidence behind them. It feels amazing to have a coach who really wants to see the company succeed and is emotionally invested in the company, and in me.

Full transcript

Joel Jean, Co-Founder and CEO of Swift Solar, in conversation with Titan. Lightly edited for clarity.

What Swift Solar is building

I'm Joel. I'm the co-founder and CEO of Swift Solar, and we're building the future of solar energy in the U.S. Solar is, bar none, the largest energy source we have in the solar system, and it's going to be the future of energy on Earth and beyond Earth.

How Swift reached a step change

In the very early days of Swift, we didn't know what the hell we were doing. We spent a lot of time wandering in the dark. In a way, it's very slow growth until you prove things out and it's ready, and then it's a step change. What's both exciting and scary right now is that we just made that step change. So as we're moving from R&D into production, there's definitely a lot of personal changes that I've had to painfully make.

How he learned to communicate vision

As a scientist, you want to talk about expectation value. You want to be, "OK, here's the median outcome of this company." And what I've had to learn is that by communicating my vision of what that 99 percentile outcome can be, I can shift the median of that curve to be at that 99 percentile outcome. And that's really powerful.

Why he chose a Titan coach

I started thinking about getting a coach many years ago. I think one of the things that held me back was the sort of activation barrier of finding a coach, and Titan is reducing that to near zero.

What I really appreciate about my coach is that he's able to be super hard-ass, really, and tell me the straight truth the way he sees it. We meet weekly and we just talk through a number of topics that are on my mind. So whether that's fundraising, a pitch deck, a customer challenge, pricing strategy, a management challenge, some personnel issue or a hiring question, anything is on the table.

Since starting coaching, I've been able to make decisions with more confidence behind them. It feels amazing to have a coach who really, really wants to see this succeed and is emotionally invested in the company and in me.

How coaching supports the next stage

Today, Swift is not just an R&D organization. We are now actually planning out our first U.S. factory, which will be producing proven bankable solar technology at gigawatt scale within two years.

There's no more important time to be building Swift Solar because we're in the middle of the U.S. separating from China. AI data centers driving unprecedented electricity demand growth and needing a ton of energy and space. All of these things point towards more energy made here in the U.S., and that is Swift Solar's mission.

To make Swift realize its full potential, I need to grow into a manufacturing CEO, not a technology development CEO. And that's something that my coach is going to be a critical part of helping me evolve into.

Titan FAQs

What is Titan?

Titan matches Series A to C founders with the best founder coaches in the world. Titan interviews each founder, then introduces them to coaches from a network of 48 who have either built an outlier company themselves or coached the founders who did. Titan is currently working with 250+ Series A to C founders of companies including Wispr, Pylon, Nooks, Attention, OpenRouter, ComfyUI, OpusClip, Unify, Mirage, Bretton and ZBiotics.

Who are Titan's coaches?

Titan has interviewed more than 1,600 coaches over 8 years and accepts fewer than 3%. Titan's coaches have all either (1) "done it themselves", meaning they built a VC-backed startup to $100M+ ARR or a $300M+ exit, or (2) "seen it done well", meaning they coached at least 6 founders from Series A to unicorn. Many Titan coaches meet both criteria. Success stories of Titan's coaches include the founders of Figma, Notion, Plaid, Rippling, Superhuman, Oura, Instagram, LinkedIn and Asana - all were coached between their Series A and Series C.

How does Titan match a founder with a coach?

  1. Titan starts with a one-hour discovery call.
  2. Titan then matches coaches/clients based on 3 main dimensions of fit:
    • (1) experience (Does the coach have outlier success in the founder's context (stage, industry, role)?)
    • (2) focus (Does the coach specialize in solving the founder's most pressing business needs?)
    • (3) personality (Does the coach's personality match the people in their life who have historically influenced them the most?)
  3. The founder receives three coach matches.
  4. The founder does trial sessions with two of them.
  5. The founder begins an engagement with one.

98% of the founders Titan places have stayed with their coach for 12 months or longer.

What does working with a Titan coach include?

All Titan coaches offer weekly or biweekly sessions plus unlimited support between sessions by text, call or email - all as part of a monthly retainer. Founders can switch coaches at any time, and the matching is a concierge service: Titan does the vetting and the introductions.

What do founders work on with a Titan coach?

Because our coaches have done it themselves, founders can work with their coach on anything. If a founder is going through it, chances are their coach (or the founders they have coached before) have also been through it in the past. That said, we have seen that founders tend to find the most leverage by working with their coach across 8 areas: (1) setting a clear strategy, (2) building a team of A players, (3) keeping everyone aligned (including co-founders, executive team, and the broader team), (4) setting clear expectations and having hard conversations, (5) creating a culture of accountability, (6) getting visibility and trust so the company runs without them, (7) protecting time and energy to avoid burnout, and (8) finding their own leadership style.

How is Titan different from other executive coaching?

What makes Titan different is:

  • The quality of coaches: nowhere else will you find coaches who have themselves built companies to over $100M+ ARR or coached 6 founders from Series A to unicorn.
  • The diversity of approaches: Titan is process agnostic and outcomes obsessed. We don't ask coaches to follow a particular program or protocol. We let their results speak for themselves. By simply gathering before-and-after financials of the companies they have built or coached, we can hold them to a standard of excellence without forcing them to dogmatically subscribe to a particular methodology. This allows Titan to support founders in many more ways than you will find anywhere else.

What happens when a company outgrows its coach?

Switching coaches at Titan is always free. Top founders change coaches every 12 to 24 months, because the problems a founder faces at Series A are different from the ones at Series C. Titan re-matches founders with the right coach as their company's stage changes.
